cd../
附：以下为附加步骤，如果你想在这台服务器上运行MySQL数据库，则执行以下几步。如果你只是希望让PHP支持MySQL扩展库，能够连接其他服务器上的MySQL数据库，那么，以下两步无需执行。

①、创建MySQL数据库存放目录

?
1
2
3
4
mkdir-p /var/mysql/data/
mkdir-p /var/mysql/binlog/
mkdir-p /var/mysql/relaylog/
chown-R mysql:mysql /var/mysql/

②、以mysql用户帐号的身份建立数据表：

?
1
2
/usr/local/mysql/bin/mysql_install_db--basedir=/usr/local/mysql--datadir=/var/mysql/data--user=mysql
/usr/local/mysql/bin/mysql_install_db--basedir=/usr/local/mysql--datadir=/var/mysql/data--user=mysql

③、创建my.cnf配置文件：

?
1
vi/var/mysql/my.cnf
启动MySQL：
?
1
/usr/local/mysql/bin/mysqld_safe--user=root
输入以下SQL语句，创建一个具有root权限的用户（admin）和密码（12345678）：
?
1
2
3
GRANT ALL PRIVILEGES ON *.* TO ‘admin‘@‘localhost‘IDENTIFIED BY ‘12345678‘;
GRANT ALL PRIVILEGES ON *.* TO ‘admin‘@‘127.0.0.1‘IDENTIFIED BY ‘12345678‘;
GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘IDENTIFIED BY ‘root‘;

tarzxvf PDO_MYSQL-1.0.2.tgz
cdPDO_MYSQL-1.0.2/

cdimagick-2.3.0/
/usr/local/php/bin/phpize
./configure--with-php-config=/usr/local/php/bin/php-config
make
makeinstall
cd../

5）修改php.ini文件

手工修改：查找/usr/local/php/etc/php.ini中的extension_dir = "./" 　 
修改为extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/" 
并在此行后增加以下几行，然后保存：
?
1
2
3
extension = "memcache.so"
extension = "pdo_mysql.so"
extension = "imagick.so"
再查找output_buffering = Off 修改为output_buffering = On 　　 
再查找; cgi.fix_pathinfo=0 　　修改为cgi.fix_pathinfo=0， 
防止Nginx文件类型错误解析漏洞。 
注：若嫌手工修改麻烦，可执行以下shell命令，自动完成对php.ini文件的修改： 
?
1
2
3
4
sed-i ‘s#extension_dir = "./"#extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\nextension = "imagick.so"\n#‘/usr/local/php/etc/php.ini
sed-i ‘s#output_buffering = Off#output_buffering = On#‘/usr/local/php/etc/php.ini
sed-i "s#; always_populate_raw_post_data = http://www.mamicode.com/On#always_populate_raw_post_data = On#g"/usr/local/php/etc/php.ini
sed-i "s#; cgi.fix_pathinfo=0#cgi.fix_pathinfo=0#g"/usr/local/php/etc/php.ini

7）创建www用户和组，以及供book.zhiyin.com和www.zhiyin.com两个虚拟主机使用的目录：

?

2
3

5
6
7
8
9
10
/usr/sbin/groupaddwww
/usr/sbin/useradd-g www www
mkdir-p /var/webroot/log
chmod+w /var/webroot/log
chown-R www:www /var/webroot/log
mkdir-p /var/webroot/web
chmod+w /var/webroot/web
chown-R www:www /var/webroot/web
 
chown-R admin:ftpgroup /var/webroot/web

8） 创建Nginx日志目录

?
1
2
3
mkdir-p /var/log/nginx
chmod+w /var/log/nginx
chown-R www:www /var/log/nginx

4） 创建Nginx配置文件

①在/usr/local/nginx/conf/目录中创建nginx.conf文件：
?
1
2
rm-f /usr/local/nginx/conf/nginx.conf
vi/usr/local/nginx/conf/nginx.conf
输入以下内容：

4 配置开机自动启动Nginx + PHP

?

vi/etc/rc.local
在末尾增加以下内容：

ulimit-SHn 65535
/usr/local/php/sbin/php-fpmstart
/usr/local/nginx/sbin/nginx
/var/mysql/mysqlstart

5 在不停止Nginx服务的情况下平滑变更Nginx配置

1）修改

/usr/local/nginx/conf/nginx.conf配置文件后，请执行以下命令检查配置文件是否正确：
?
1
/usr/local/nginx/sbin/nginx-t
如果屏幕显示以下两行信息，说明配置文件正确：

the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully

2） 平滑重启：

①、对于Nginx 0.8.x版本，现在平滑重启Nginx配置非常简单，执行以下命令即可：
?
1
/usr/local/nginx/sbin/nginx-s reload
②、对于Nginx 0.8.x之前的版本，平滑重启稍微麻烦一些，按照以下步骤进行即可。输入以下命令查看Nginx主进程号：
?
1
ps-ef | grep"nginx: master process"| grep-v"grep"| awk-F ‘ ‘‘{print $2}‘
屏幕显示的即为Nginx主进程号，例如： 　　6302 这时，执行以下命令即可使修改过的Nginx配置文件生效：
?
1
kill-HUP 6302
或者无需这么麻烦，找到Nginx的Pid文件：
?
1
kill-HUP `cat/usr/local/nginx/nginx.pid`

6 优化Linux内核参数 (此处内容不推荐使用)

?
1
vi/etc/sysctl.conf

使配置立即生效：

/sbin/sysctl-p

引用来自“mark35”的答案

之所以YUM安装的PHP会有那么多 --disable参数，那是为了你以后单独安装部件考虑的。你可以通过 YUM install php-??? 来安装需要部件，比如

?
1
yum installphp-mysql php-gd

相当于只安装了PHP核心，扩展包按需安装

 

可是我执行了
?
1
yum installphp-mysql

 

Centos下配置php环境
