LNAMP源码安装整合加论坛及动静分离

fdsfdfe 发表于 2015-8-14 08:45:42

LNAMP(Linux+Nginx+Apache+Mysql+PHP)架构受到很多IT企业的青睐,取代了原来认为很好的LNMP(Linux+Nginx+Mysql+PHP)架构,那我们说LNAMP到底有什么优点呢,还得从Nginx和apache的优缺点说起。Nginx处理静态文件能力很强,Apache处理动态文件很强而且很稳定,把二者综合在一块,性能提升很多倍。可能很多Linux SA在从事LNMP运维中，会发现PHP（FastCGI）模式会出现一些502错误的现象，这是因为Nginx+PHP（FastCGI）组合不稳定的原因造成的。

然后在论坛页面输入账号信息一路下一步就安装成功了。。。。。。。。。。

自此LAMP环境整合并搭建成功，那如何使用Nginx来整合LAMP呢？

[*]源码安装Nginx+LAMP整合
先修改apache访问端口为8080，Nginx端口默认为80然后修改nginx配置文件: vi/usr/local/nginx/conf/nginx.conf，server配置段内容如下：(定义upstream均衡模块，配置动静分离，动态转发至apache，静态文件直接本地响应),这里配置的有动静分离，，动态走app_lamp;模块静态走本地目录，，由于一台机器上实现，有点局限性，理解：

server {
   listen    80;
   server_namelocalhost;

   location / {
         root /usr/local/apache/htdocs;
         index index.php index.html index.htm;

      proxy_set_header X-Forwarded-For$proxy_add_x_forwarded_for;
      proxy_pass http://app_lamp;
}
   location ~.*\.(html|htm|gif|jpg|jpeg|bmp|png|ico|txt|js|css)$
   {
   root /usr/local/apache/htdocs;
   expires    3d;
   }
}

在客户端输入http://192.168.77.189可以直接访问，，动态图片图片程序走app_lamp模块里面的主机，当然可以是另外的机器，静态网页走的是本地

自此，LNAMP源码全部整合完毕
