安装完成之后 安装 nginx
./configure --with-http_stub_status_module –prefix=/usr/local/nginx
make
make install
就这样nginx 安装完成 启动nginx 命令如下 ./nginx & 如果通过http://localhost 能够访问的话 表示安装成功 /如图:
安装成功后 /usr/local/nginx 目录下有四个子目录分别是:conf、html、logs、sbin 。其中 Nginx 的配置文件存放于 conf/nginx.conf,Nginx 只有一个程序文件位于 sbin 目录下的 nginx 文件。
打开nginx.conf配置文件 修改后内容如下: #user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {

}

动态页面请求处理:
Nginx 本身并不支持现在流行的 JSP、ASP、PHP、PERL 等动态页面,但是它可以通过反向代理将请求发送到后端的服务器,例如 Tomcat、Apache、IIS 等来完成动态页面的请求处理。前面的配置示例中,我们首先定义了由 Nginx 直接处理的一些静态文件请求后,其他所有的请求通过 proxy_pass 指令传送给后端的服务器(在上述例子中是 Tomcat)。最简单的 proxy_pass 用法如下:
location / {
proxy_pass http://localhost:8080;
proxy_set_header X-Real-IP $remote_addr;
}
在本例中我们配置的是2台机器的负载均衡 所以我们的配置是 :
location /they{
proxy_pass http://mao;# 反向代理
#include proxy.conf;
}
其中 mao 是我们用upstream 来定义的 例如:
upstream mao{
server 192.168.0.208:8080 weight=2;
server 192.168.0.235 weight=3;
}
在 Nginx 的集群配置中,Nginx 使用最简单的平均分配规则给集群中的每个节点分配请求。一旦某个节点失效时,或者重新起效时,Nginx 都会非常及时的处理状态的变化,以保证不会影响到用户的访问。
