nginx反向代理配置实例(前nginx+后apache)
Nginx ("engine x") 是一个高性能的 HTTP 和反向代理服务器,也是一个 IMAP/POP3/SMTP 代理服务器。 Nginx 是由 Igor Sysoev 为俄罗斯访问量第二的 Rambler.ru 站点开发的,它已经在该站点运行超过三年了。Igor 将源代码以类BSD许可证的形式发布。Nginx 超越 Apache 的高性能和稳定性,使得国内使用 Nginx 作为 Web 服务器的网站也越来越多,大部分门户网站都把它作为首选WEB前端。
nginx与apache相比,处理静态页面很强大,对于动态页面,它不及apache
用nginx 前台处理静态http请求,用apache后台处理php动态页面。
主机用相同的根目录,但访问的端口不一样。nginx 用80,apache用88。当访问http://10.0.0.99的时候,你访问的是(nginx),它会在根目录下面查找静态文件(css ,gif,html ·······),如果找到它会把信息直接返回给浏览器,如果找不到(像.php的文件),它会通过( proxy_pass: http://10.0.0.99:88/;)转向apache相对应的路径请求。
一、安装nginx
nginx安装需要 pcre 源码的支持
建立用户及组
[root@localhost /]# /usr/sbin/groupadd www [root@localhost /]# /usr/sbin/useradd -g www www [root@localhost ~]# cd /home/admin/ [root@localhost admin]# tar zvxf nginx-1.5.6.tar.gz [root@localhost admin]# cd nginx-1.5.6 [root@localhost nginx-1.5.6]# mkdir /usr/local/nginx [root@localhost nginx-1.5.6]# ./configure --user=www --group=www \ --prefix=/usr/local/nginx \ --with-http_stub_status_module \ --with-openssl=/usr \ --with-pcre=/home/admin/pcre-8.33 \#pcre源码包路径 --with-cc-opt='-O2'\ --with-cpu-opt=你的cpu型号
注意:--with-pcre=/home/admin/pcre-8.33指向的是源码包解压的路径,而不是安装的路径,否则会报错
[root@localhost nginx-1.5.6]# make && make install
#注意上文中的--with-cc-opt='-O2' --with-cpu-opt=opteron 这是编译器优化,目前最常用的是-02 而不是3.后面对应CPU的型号
#启动nginx
[root@localhost nginx-1.5.6]# /usr/local/nginx/sbin/nginx
Nginx开启命令:/usr/local/nginx/sbin/nginx
Nginx停止命令: /usr/local/nginx/sbin/nginx -s stop
Nginx的热启动:#usr/local/nginx/sbin/nginx -s reload
#修改配置文件
[root@localhost nginx-1.5.6]# cd /usr/local/nginx/conf/ [root@localhost conf]# cp nginx.conf nginx.conf.back #备份
nginx 处理下图片,html等静态的东西.其它动态由apache处理.因此apache也需要做一些参数调整.
设置图片等过期时间.缓解请求.
[root@localhost conf]# vi nginx.conf

---------------
修改apache配置文件
Listen 80 #修改成你的端口 <VirtualHost *:80> #依据你的环境修改 ServerName 10.0.0.99 DocumentRoot "/home/wwwroot" </VirtualHost>
