nginx做反向代理+apache
先上个规划图,自己随便画的,大家也随便看看
192.168.1.119为nginx做反向代理并处理静态页面,apache处理动态页面,nfs共享网站家目录,svn代码管理。
192.168.101为apache处理动态页面,挂载192.168.1.119的共享目录。
192.168.1.96为mysql数据库,允许两台web服务的连接权限。
系统使用centos6.5
一,配置192.168.1.119
1.首先在192.168.1.119上安装nginx+apache+php+nfs+svn
yum install -y nginx httpd php php-mysql nfs-utils portmap subversion
2.修改nginx配置文件
vim /etc/nginx/nginx.conf user www www; worker_processes auto; error_log /home/wwwlogs/nginx_error.log crit; pid /usr/local/nginx/logs/nginx.pid; #Specifies the value for maximum file descriptors that can be opened by this process. worker_rlimit_nofile 51200; events { use epoll; worker_connections 51200; multi_accept on; } http { include mime.types; default_type application/octet-stream; server_names_hash_bucket_size 128; client_header_buffer_size 32k; large_client_header_buffers 4 32k; client_max_body_size 50m; sendfile on; tcp_nopush on; keepalive_timeout 60; tcp_nodelay on; fastcgi_connect_timeout 300; fastcgi_send_timeout 300; fastcgi_read_timeout 300; fastcgi_buffer_size 64k; fastcgi_buffers 4 64k; fastcgi_busy_buffers_size 128k; fastcgi_temp_file_write_size 256k; gzip on; gzip_min_length 1k; gzip_buffers 4 16k; gzip_http_version 1.0; gzip_comp_level 2; gzip_types text/plain application/x-javascript text/css application/xml; gzip_vary on; gzip_proxied expired no-cache no-store private auth; gzip_disable "MSIE [1-6]\."; #limit_conn_zone $binary_remote_addr zone=perip:10m; ##If enable limit_conn_zone,add "limit_conn perip 10;" to server section. #log format log_format access ‘$remote_addr - $remote_user [$time_local] "$request" ‘ ‘$status $body_bytes_sent "$http_referer" ‘ ‘"$http_user_agent" $http_x_forwarded_for‘; upstream backend_http { server 192.168.1.101:80; server 127.0.0.1:88; } server { listen 80 default; #listen [::]:80 default ipv6only=on; server_name 192.168.1.119; index index.html index.htm index.php; root /home/wwwroot/repo; access_log logs/access.log combined; #location / { # try_files $uri @apache; # } #location @apache { # internal; # proxy_pass http://127.0.0.1:88; # include proxy.conf; # } location ~ [^/]\.php(/|$) { proxy_pass http://backend_http; include proxy.conf; } location /nginx_status { stub_status on; access_log off; } location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ { expires 30d; } location ~ .*\.(js|css)?$ { expires 12h; } access_log /home/wwwlogs/access.log access; } include vhost/*.conf; } 检查配置文件 nginx -t 启动服务 nginx 重新加载配置 nginx -s reload
3.修改apache配置文件
vim /etc/httpd/conf/httpd.conf <VirtualHost *:80> ServerAdmin charlie.cen@tappal.com DocumentRoot /home/wwwroot/repo ServerName 192.168.1.119 </VirtualHost> 启动服务 service httpd start chkconfig httpd on
4.创建svn仓库
mkdir /opt/svn && svnadmin create /opt/svn/repo 使用密码认证 vim /opt/svn/repo/conf/svnerve.conf password = 取消这行的注释 添加用户和密码 echo "charlie = charlie" >> /opt/svn/repo/conf/passwd 启动服务 svnserve -d -r /opt/svn 取出svn仓库 cd /home/wwwroot svn co svn://localhost/repo 修改svn更新后直接到网站家目录 cd /opt/svn/repo/hooks cp post-commit.tmpl post-commit vim post-commit export LANG=en_CN.UTF-8 svn update /home/wwwroot/repo --username charlie --password charlie --no-auth-cache #mailer.py commit "$REPOS" "$REV" /path/to/mailer.conf (此行注释) 添加执行权限 chmod +x post-commit
5.配置共享目录
vim /etc/exports /home/wwwroot/repo 192.168.1.0/24(sync,rw,no_root_squash) 启动服务 /etc/init.d/rpcbind start /etc/init.d/nfs start 查看共享目录 exportfs -v 加载共享目录使生效 exportfs -r
二,配置192.168.1.101
6.安装httpd
yum install -y httpd php php-mysql
7.配置apache
vim /etc/httpd/conf/httpd.conf <VirtualHost *:80> ServerAdmin charlie.cen@tappal.com DocumentRoot /home/wwwroot/repo ServerName 192.168.1.101 </VirtualHost>
8.挂载共享目录
mkdir /home/wwwroot/repo -pv mount -t nfs 192.168.1.119:/home/wwwroot/repo /home/wwwroot/repo
9.启动服务
service httpd start chkconfig httpd on
三,安装mysql
10.安装mysql
yum install -y mysql mysql-server
11.启动服务
service mysqld start chkconfig mysqld on
12.mysql创建密码
mysqladmin -uroot -password charlie
13.授权用户
mysql -uroot -pcharlie grant all on *.* to charlie@‘192.168.1.%‘ identified by ‘charlie‘; flush privileges;
四,测试网站
14.svn导出到本地
新建个测试页面
然后访问测试
刷新后版本不同,证明客户端请求php页面会轮询给后端的apache服务器。
如果客户端请求的页面不能保持会话,会经常切换页面导致用户账户登录等问题,所以需要更改nginx配置
添加ip_hash保持会话连接,然后重启nginx -s reload
再次刷新页面不会切换
测试连接数据库,下面页面是测试页
添加并确认
到两台网站服务器上查看是否存在该文件,并检查内容是否一致!
然后访问,证明成功连接后端数据库
