基于Centos 6.5 配置分离式LAMP平台环境的一次扩展实现多PHP Apache和自建DNS来提升LAMP的负载
要达到的目的
双Apache+PHP能正常的被DNS轮询解析到
Apache 1 2 服务器能正常访问NFS上的静态资源
PHP 1 2 服务器能正常访问NFS上的PHP资源
Apache 1 2 和PHP 1 2服务器都能和MariaDB数据库服务器通信
最终实现低价格提高网站负载的方案
由于这里使用了7台服务器所以下文区别服务器的方法请看命令行的[root@LookBack163 ~]这个字段
| 服务器编号 | 服务器IP | 服务器安装的服务 | 服务器系统 |
| LookBack163 | 172.16.41.163 | Apache 1 | Centos 6.5 x86_64 |
| LookBack164 | 172.16.41.164 | PHP 1 | Centos 6.5 x86_64 |
| LookBack165 | 172.16.41.165 | MariaDB | Centos 6.5 x86_64 |
| LookBack166 | 172.16.41.166 | Apache 1 | Centos 6.5 x86_64 |
| LookBack167 | 172.16.41.167 | PHP 1 | Centos 6.5 x86_64 |
| LookBack168 | 172.16.41.168 | DNS | Centos 6.5 x86_64 |
| LookBack169 | 172.16.41.169 | NFS | Centos 6.5 x86_64 |
这里采取了7个VMware的虚拟机一台VMware的Windows虚拟机做测试
下面是基础的原理图
一、配置两台Apache2.4.x服务器在172.16.41.163和172.16.41.166服务器上
1.1编译安装Apache 2.4.x

配置172.16.41.163的虚拟主机
[root@LookBack163 ~]# mkdir -p /web/hosta [root@LookBack163 ~]# grep ‘^[^#]‘ /etc/httpd2410/extra/httpd-vhosts.conf | grep -vE ‘^[[:space:]]+#‘ServerAdmin admin@05hd.com ServerName www1.05hd.com DocumentRoot "/home/wwwroot/www.05hd.com/"Require all grantedSetHandler server-status Require all grantedProxyRequests Off ProxyPassMatch ^/(.*.php)$ fcgi://172.16.41.164:9000/home/wwwroot/www.05hd.com/$1 ErrorLog "logs/www1.05hd.com-error_log" CustomLog "logs/www1.05hd.com-access_log" common
配置好Apache和虚拟主机下面来启动httpd服务
[root@LookBack163 ~]# service httpd2410 start Starting httpd: [ OK ] [root@LookBack163 ~]# service httpd2410 status httpd (pid 13827) is running... [root@LookBack163 ~]#
配置172.16.41.166的虚拟主机
[root@LookBack166 ~]# mkdir -p /web/hosta [root@LookBack166 ~]# grep ‘^[^#]‘ /etc/httpd2410/extra/httpd-vhosts.conf | grep -vE ‘^[[:space:]]+#‘ServerAdmin admin@05hd.com ServerName www1.05hd.com DocumentRoot "/home/wwwroot/www.05hd.com/"Require all grantedSetHandler server-status Require all grantedProxyRequests Off ProxyPassMatch ^/(.*.php)$ fcgi://172.16.41.167:9000/home/wwwroot/www.05hd.com/$1 ErrorLog "logs/www1.05hd.com-error_log" CustomLog "logs/www1.05hd.com-access_log" common

二、配置MariaDB 5.5.x 在172.16.41.165服务器上
2.1为了使数据库的数据安全这里还是采取在MariaDB服务器先做LVM
[root@LookBack165 ~]# fdisk /dev/sda &> /dev/null > /etc/fstab [root@LookBack165 ~]# mount -a [root@LookBack165 ~]# mount /dev/mapper/vg0-root on / type ext4 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw) /dev/sda1 on /boot type ext4 (rw) /dev/mapper/vg0-usr on /usr type ext4 (rw) /dev/mapper/vg0-var on /var type ext4 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) /dev/mapper/MYDATA-MYDATAlv on /MYSQLDATA type ext4 (rw) [root@LookBack165 ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg0-root 20G 924M 18G 5% / tmpfs 935M 0 935M 0% /dev/shm /dev/sda1 194M 35M 150M 19% /boot /dev/mapper/vg0-usr 9.9G 2.4G 7.1G 26% /usr /dev/mapper/vg0-var 20G 433M 19G 3% /var /dev/mapper/MYDATA-MYDATAlv 20G 172M 19G 1% /MYSQLDATA
2.2配置MariaDB
[root@LookBack165 ~]# groupadd -r mysql [root@LookBack165 ~]# mkdir /MYSQLDATA/data [root@LookBack165 ~]# useradd -g mysql -r -s /sbin/nologin -M -d /MYSQLDATA/data mysql [root@LookBack165 ~]# chown -R mysql:mysql /MYSQLDATA/data/ [root@LookBack165 ~]# wget http://mirrors.hustunique.com/mariadb/mariadb-galera-5.5.38/bintar-centos5-amd64/mariadb-galera-5.5.38-linux-x86_64.tar.gz [root@LookBack165 ~]# tar xf mariadb-galera-5.5.38-linux-x86_64.tar.gz -C /usr/local [root@LookBack165 ~]# cd /usr/local/ [root@LookBack165 local]# ls bin etc games glibc-2.19 include lib lib64 libexec mariadb-galera-5.5.38-linux-x86_64 sbin share src [root@LookBack165 local]# ln -sv mariadb-galera-5.5.38-linux-x86_64/ mariadb `mariadb‘ -> `mariadb-galera-5.5.38-linux-x86_64/‘ ###` [root@LookBack165 local]# cd mariadb [root@LookBack165 mariadb]# chown -R mysql:mysql .
2.3初始化MariaDB
[root@LookBack165 mariadb]# pwd /usr/local/mariadb [root@LookBack165 mariadb]# scripts/mysql_install_db --user=mysql --datadir=/MYSQLDATA/data/ WARNING: The host ‘LookBack165.05hd.com‘ could not be looked up with resolveip. This probably means that your libc libraries are not 100 % compatible with this binary MariaDB version. The MariaDB daemon, mysqld, should work normally with the exception that host name resolving will not work. This means that you should use IP addresses instead of hostnames when specifying MariaDB privileges !

To do so, start the server, then issue the following commands: ‘./bin/mysqladmin‘ -u root password ‘new-password‘ ‘./bin/mysqladmin‘ -u root -h LookBack165.05hd.com password ‘new-password‘ Alternatively you can run: ‘./bin/mysql_secure_installation‘ which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers. See the MariaDB Knowledgebase at http://mariadb.com/kb or the MySQL manual for more instructions. You can start the MariaDB daemon with: cd ‘.‘ ; ./bin/mysqld_safe --datadir=‘/MYSQLDATA/data/‘ You can test the MariaDB daemon with mysql-test-run.pl cd ‘./mysql-test‘ ; perl mysql-test-run.pl Please report any problems at http://mariadb.org/jira The latest information about MariaDB is available at http://mariadb.org/. You can find additional information about the MySQL part at: http://dev.mysql.com Support MariaDB development by buying support/new features from SkySQL Ab. You can contact us about this at sales@skysql.com. Alternatively consider joining our community based development effort: http://mariadb.com/kb/en/contributing-to-the-mariadb-project/ [root@LookBack165 mariadb]# chown -R root .

2.4修改MariaDB配置文件
[root@LookBack165 mariadb]# cd /usr/local/mariadb [root@LookBack165 mariadb]# cp support-files/my-large.cnf /etc/my.cnf ###并修改此文件中thread_concurrency的值为你的CPU个数乘以2，比如这里使用如下行： thread_concurrency = 2 ###[root@LookBack165 mariadb]# sed -i "@^thread_concurrency.*@thread_concurrency = 2@" /etc/my.cnf###也可以用这个命令直接修改 [root@LookBack165 mariadb]# sed -i "/^thread_concurrency.*/i \datadir = \/MYSQLDATA\/data" /etc/my.cnf
2.5制作配置MariaDB启动脚本等
[root@LookBack165 mariadb]# cp /usr/local/mariadb/support-files/mysql.server /etc/rc.d/init.d/mysql
[root@LookBack165 mariadb]# chmod +x /etc/rc.d/init.d/mysql
[root@LookBack165 mariadb]# chkconfig --add mysql
[root@LookBack165 mariadb]# chkconfig --list mysql
mariadb 0:off 1:off 2:on 3:on 4:on 5:on 6:off
[root@LookBack165 mariadb]# sed -i ‘s@/usr/local/mysql@/usr/local/mariadb@‘ /etc/rc.d/init.d/mysql
[root@LookBack165 mariadb]# service mysql start
Starting MySQL..... [ OK ]
[root@LookBack165 mariadb]# service mysql stop
Shutting down MySQL. [ OK ]
[root@LookBack165 mariadb]# sed -i "$(cat /etc/man.config | grep -nE ‘^MANPATH[[:space:]]+‘ | tail -1 | awk -F: ‘{print$1}‘)a MANPATH\t/usr/local/mariadb/man" /etc/man.config
[root@LookBack165 mariadb]# ln -sv /usr/local/mariadb/include /usr/include/mysql
[root@LookBack165 mariadb]# echo ‘/usr/local/mariadb/lib/‘ > /etc/ld.so.conf.d/mysql.conf
[root@LookBack165 mariadb]# ldconfig
[root@LookBack165 mariadb]# echo "export PATH=/usr/local/mariadb/bin:$PATH" > /etc/profile.d/mariadb5538.sh2.6修改MariaDB root帐户的空密码和建立两个用于PHP1 PHP2服务器的远程帐号并有权限
###1.这里将MariaDB root的密码修改成了YTJmZjQ5NThiMGNl,
###2.新建了一个05hdtest的帐号和同名的数据库
###3.设置05hdtest这个帐号允许在172.16.41.164和172.16.41.167服务器上连接使用
###4.设置05hdtest帐号的权限是同名数据库的全部权限
###5.设置05hdtest帐号登录的密码是Fa7A29f67eJ3RRHu

四、在服务器172.16.41.168上编译安装BIND 做DNS服务器
让访问域名www1.05hd.com的时候DNS轮询到172.16.41.163和172.16.41.166服务器上
4.1编译安装BIND 9.9.x
[root@LookBack168 ~]# groupadd -g 153 -r named [root@LookBack168 ~]# useradd -g named -r -u 153 named [root@LookBack168 ~]# yum groupinstall "Development tools" "Server Platform Development" -y [root@LookBack168 ~]# wget -4c http://www.05hd.com/wp-content/uploads/2014/08/bind-9.9.5.tar.gz [root@LookBack168 ~]# tar xf bind-9.9.5.tar.gz [root@LookBack168 ~]# cd bind-9.9.5 [root@LookBack168 bind-9.9.5]# ./configure --prefix=/usr/local/bind995 --sysconfdir=/etc/named --disable-chroot --enable-threads --enable-ipv6 [root@localhost bind-9.9.5]# make -j4 && make install
4.2修改环境变量和添加named的man
(注意：修改了环境变量需要重启服务器或者重新载入环境变量)
[root@LookBack168 ~]# /usr/local/bind995/bin/dig -v
[root@localhost ~]# echo "export PATH=/usr/local/bind995/bin:/usr/local/bind995/sbin:\$PATH" > /etc/profile.d/bind995.sh
[root@LookBack168 ~]# echo $PATH
/usr/lib64/qt-3.3/bin:/usr/local/bind995/bin:/usr/local/bind995/sbin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
[root@LookBack168 ~]# sed -i "$(cat /etc/man.config | grep -nE ‘^MANPATH[[:space:]]+‘ | tail -1 | awk -F: ‘{print$1}‘)a \MANPATH\t/usr/local/bind995/share/man" /etc/man.config4.3 配置BIND
[root@LookBack168 ~]# cat > /etc/named/named.conf << EOF
options {
directory "/var/named";
//定义工作目录
recursion yes;
//允许递归
};
zone "." IN {
type hint;
file "named.ca";
};
zone "localhost" IN {
type master;
//定义为主DNS master
file "localhost.zone";
allow-update { none; };
//不允许任何人更新
};
zone "0.0.127.in-addr.arpa" IN {
//把127.0.0反向解析
type master;
file "127.0.0.zone";
allow-update { none; };
};
zone "05hd.com" IN {
type master;
file "05hd.com.zone";
};
EOF
[root@LookBack168 ~]# chown root:named /etc/named/named.conf
[root@LookBack168 ~]# chmod 640 /etc/named/named.conf
[root@LookBack168 ~]# mkdir -p /var/named/slaves
[root@LookBack168 ~]# chown root:named /var/named/
[root@LookBack168 ~]# chown named:named /var/named/slaves/
[root@LookBack168 ~]# chmod 750 /var/named/
[root@LookBack168 ~]# chmod 770 /var/named/slaves/
[root@LookBack168 ~]# for i in $(grep ‘file‘ /etc/named/named.conf | awk -F‘"‘ ‘{print$2}‘); do touch /var/named/$i;chgrp named /var/named/$i;chmod 640 /var/named/$i;done
4.4配置05hd.com.zone 127.0.0.zone localhost.zone named.ca这4个文件
[root@LookBack168 bind-9.9.5]# dig -t NS . @a.root-servers.net. > /var/named/named.ca [root@LookBack168 bind-9.9.5]# cat !$ cat /var/named/named.ca ; > DiG 9.8.2rc1-RedHat-9.8.2-0.17.rc1.el6_4.6 > -t NS . @a.root-servers.net. ;; global options: +cmd ;; Got answer: ;; ->>HEADER: QUERY, status: NOERROR, id: 2346 ;; flags: qr rd ra; QUERY: 1, ANSWER: 13, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;.

4.5配置制作BIND的启动脚本并启动DNS服务
[root@LookBack168 ~]# wget -c4 http://www.05hd.com/named.sh -O /etc/rc.d/init.d/named [root@LookBack168 ~]# sed -ri "s@^# chkconfig.*@# chkconfig: 2345 25 80\n# Default-Start: 2 3 4 5\n# Default-Stop: 0 1 6@" /etc/rc.d/init.d/named [root@LookBack168 ~]# chmod +x /etc/rc.d/init.d/named [root@LookBack168 ~]# chkconfig --add named [root@LookBack168 ~]# chkconfig --list named named 0:off 1:off 2:on 3:on 4:on 5:on 6:off [root@LookBack168 ~]# service named start Starting named: [ OK ] [root@LookBack168 ~]# service named stop Stopping named: [ OK ] [root@LookBack168 ~]# service named start Starting named: [ OK ] [root@LookBack168 ~]# service named restart Stopping named: [ OK ] Starting named: [ OK ] [root@LookBack168 ~]# service named status named is running...

4.6测试DNS轮询 Apache1 Apache2 PHP1 PHP2服务器运行是否正常
五、配置NFS服务器
5.1启动NFS服务
由于NFS是直接在内核中的一种服务，所以我们需要再安装，免去了编译安装或者RPM包安装了(心里很高兴。。。。。。)
[root@LookBack169 ~]# service nfs start Starting NFS services: [ OK ] Starting NFS quotas: [ OK ] Starting NFS mountd: [ OK ] Starting NFS daemon: [ OK ] Starting RPC idmapd: [ OK ]
5.2配置NFS共享文件
[root@LookBack169 ~]# sed -ri "s@^# chkconfig.*@# chkconfig: 2345 30 60\n# Default-Start: 2 3 4 5\n# Default-Stop: 0 1 6@" /etc/rc.d/init.d/nfs
[root@LookBack169 ~]# chkconfig --level 2345 rpcbind on
[root@LookBack169 ~]# chkconfig --level 2345 nfs on
[root@LookBack169 ~]# chkconfig --list nfs
nfs 0:off 1:off 2:off 3:off 4:off 5:off 6:off
[root@LookBack169 ~]# chkconfig --list rpcbind
rpcbind 0:off 1:off 2:on 3:on 4:on 5:on 6:off
[root@LookBack169 ~]# mkdir -pv /home/wwwroot/www.05hd.com
mkdir: created directory `/home/wwwroot`
mkdir: created directory `/home/wwwroot/www.05hd.com`
[root@LookBack169 ~]# useradd -u 600 www
[root@LookBack169 ~]# setfacl -m u:www:rwx /home/wwwroot/www.05hd.com/
###上面的命令需要目录的所在分区在挂载时有acl选项挂载，否则是写入不了facl权限的
[root@LookBack169 ~]# wwwUID=$(id www | awk -F‘[= (]‘ ‘{print$2}‘)
[root@LookBack169 ~]# wwwGID=$(id www | awk -F‘[= (]‘ ‘{print$5}‘)
[root@LookBack169 ~]# NFSInfo="anonuid=${wwwUID},anongid=${wwwGID},rw,sync"
[root@LookBack169 ~]# echo "/home/wwwroot/www.05hd.com 172.16.41.163(${NFSInfo}) 172.16.41.164(${NFSInfo}) 172.16.41.166(${NFSInfo}) 172.16.41.167(${NFSInfo})" > /etc/exports
[root@LookBack169 ~]# exportfs -arv
exporting 172.16.41.163:/home/wwwroot/www.05hd.com
exporting 172.16.41.164:/home/wwwroot/www.05hd.com
exporting 172.16.41.166:/home/wwwroot/www.05hd.com
exporting 172.16.41.167:/home/wwwroot/www.05hd.com
###exportfs -arv 用于重新导出nfs文件系统表
###exportfs -auv 用于关闭导出所有的文件系统表
###exportfs -Uv FS 用于关闭指定的文件系统表
[root@LookBack169 ~]# showmount -e 172.16.41.169
Export list for 172.16.41.169:

下面是一些NFS共享的常用参数： ro 只读访问 rw 读写访问 sync 所有数据在请求时写入共享 async NFS在写入数据前可以相应请求 secure NFS通过1024以下的安全TCP/IP端口发送 insecure NFS通过1024以上的端口发送 wdelay 如果多个用户要写入NFS目录，则归组写入（默认） no_wdelay 如果多个用户要写入NFS目录，则立即写入，当使用async时，无需此设置。 hide 在NFS共享目录中不共享其子目录 no_hide 共享NFS目录的子目录 subtree_check 如果共享/usr/bin之类的子目录时，强制NFS检查父目录的权限（默认） no_subtree_check 和上面相对，不检查父目录权限 all_squash 共享文件的UID和GID映射匿名用户anonymous，适合公用目录。 no_all_squash 保留共享文件的UID和GID（默认） root_squash root用户的所有请求映射成如anonymous用户一样的权限（默认） no_root_squas root用户具有根目录的完全管理访问权限 anonuid=xxx 指定NFS服务器/etc/passwd文件中匿名用户的UID anongid=xxx 指定NFS服务器/etc/passwd文件中匿名用户的GID

六、在这个分离式的LAMP上架设一个站点来各种测试下
6.1下载一个Discuz的BBS程序
[root@LookBack169 wwwroot]# pwd /home/wwwroot [root@LookBack169 wwwroot]# wget http://download.comsenz.com/DiscuzX/3.2/Discuz_X3.2_SC_UTF8.zip [root@LookBack169 wwwroot]# ls Discuz_X3.2_SC_UTF8.zip [root@LookBack169 wwwroot]# unzip Discuz_X3.2_SC_UTF8.zip [root@LookBack169 wwwroot]# mv upload/* www.05hd.com/ [root@LookBack169 wwwroot]# ls www.05hd.com/ admin.php api.php config cp.php data forum.php home.php install misc.php portal.php search.php static uc_client userapp.php api archiver connect.php crossdomain.xml favicon.ico group.php index.php member.php plugin.php robots.txt source template uc_server
下面我们去测试安装这个BBS程序
首先清除测试使用的Windows系统上的DNS缓存
下面打开www1.05hd.com的地址
由于这里是测试所以下面在改变权限的时候 直接做777的权限 在正式使用的时候不建议这样做
[root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/config/config_global.php [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/config/config_ucenter.php [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/config [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/data [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/data/cache [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/data/avatar [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/data/plugindata [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/data/download [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/data/addonmd5 [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/data/template [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/data/threadcache [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/data/attachment [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/data/attachment/album [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/data/attachment/forum [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/data/attachment/group [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/data/log [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/uc_client/data/cache [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/uc_server/data/ [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/uc_server/data/cache [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/uc_server/data/avatar [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/uc_server/data/backup [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/uc_server/data/logs [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/uc_server/data/tmp [root@LookBack169 wwwroot]# chmod -R 777 /home/wwwroot/www.05hd.com/uc_server/data/view
上面的权限修改好之后 就能过BBS程序的文件权限检测了
安装好了我们来测试
至此我们的分离式LAMP环境就做好了。
双Apache+PHP能正常的被DNS轮询解析到
Apache 1 2 服务器能正常访问NFS上的静态资源
PHP 1 2 服务器能正常访问NFS上的PHP资源
Apache 1 2 和PHP 1 2服务器都能和MariaDB数据库服务器通信
