nginx安装及简单优化

一、安装

1.编译安装nginx

检查依赖：

rpm -qa pcre pcre-devel

rpm -qa openssl-devel openssl

下载:wgethttp://nginx.org/download/nginx-1.9.9.tar.gz

新建用户:useradd nginx -s /sbin/nologin -M

编译安装:

./configure --user=nginx --group=nginx --prefix=/home/nginx/nginx-1.9.9/ --with-http_stub_status_module --with-http_ssl_module

make && make install

2.启动：

/sbin/nginx 

二、优化

1.使用incloud方法简化规范配置文件

2.隐藏nginx版本号：

3.优化nginx进程数：

4 一般是服务器cpu内核数

4.优化绑定不同进程到不同cpu上面：

 0001 0010 0100 1000 分别代表0 1 2 3这四个cpu

nginx -t 验证配置文件是否正确

nginxnginx -s reload 重新加载配置文件
