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。

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:
upstreamapp_lamp { server 127.0.0.1:8080 weight=1 max_fails=2 fail_timeout=30s; } server { listen 80; server_name localhost; location / { root /usr/local/apache/htdocs; index index.php index.html index.htm; } location ~ .*\.(php|jsp|cgi)?$ { proxy_set_header Host $host; proxy_set_header X-Real-IP$remote_addr; 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
软件包太大无法上传。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。
