CentOS 7 安装Nginx-1.9.2

「个人记录，肯定有理解错误和理解不透的地方，小白总是有个成长的过程，希望大家多多指教。」

一、准备工作：

1、安装必备工具：

$ yum -y install gcc gcc-c++ autoconf automake

$ yum -y install zlib zlib-devel openssl openssl-devel pcre-devel

说明：

pcre: 用来作地址重写的功能。

zlib：nginx 的gzip模块,传输数据打包，省流量（但消耗资源）。

openssl：提供ssl加密协议。

2、新建一个系统级用户组和匿名用户，以及下面编译时使用

$ sudo groupadd -r nginx-group

$ sudo useradd -s /sbin/nologin -g nginx-group -r nginx-user

二、Nginx编译安装：

1、下载Nginx：http://nginx.org/en/download.html

2、解压编译：

$ tar -zxvf nginx-1.9.2.tar.gz

$ cd nginx-1.9.2/

$ ./configure --prefix=/usr --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --pid-path=/var/run/nginx/nginx.pid --lock-path=/var/lock/nginx.lock --user=nginx-user --group=nginx-group --with-http_ssl_module --with-http_flv_module --with-http_gzip_static_module --http-log-path=/var/log/nginx/http.log --http-client-body-temp-path=/var/tmp/nginx/client --http-proxy-temp-path=/var/tmp/nginx/proxy --http-fastcgi-temp-path=/var/tmp/nginx/fcgi --with-http_stub_status_module

上面的参数的作用可以通过--help来查看

$ ./configure --help

好像很成功。

3、安装:

$ make && make install

4、启动：

$ nginx

如果提示缺什么包，直接用yum安装

$ yum install xxxxx

如果提示：

nginx: [emerg] mkdir() "/var/tmp/nginx/client" failed (2: No such file or directory)

则用管理员去mkdir 文件夹后再启动。
