Linux 编译安装 Nginx

Nginx的安装依赖于以下三个包，意思就是在安装Nginx之前首先必须安装一下的三个包，安装顺序为以下的顺序：

1、SSL功能需要openssl库，下载地址：http://www.openssl.org/

2、gzip模块需要zlib库，下载地址：http://www.zlib.net/

3、rewrite模块需要pcre库，下载地址：http://www.pcre.org/

4、Nginx的安装包：下载地址为：http://nginx.org/en/download.html

CentOS系统 安装编译工具及库文件：

# yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel

命令下载：

wget http://www.zlib.net/zlib-1.2.11.tar.gz

wget https://www.openssl.org/source/openssl-1.0.2l.tar.gz

wget https://ftp.pcre.org/pub/pcre/pcre-8.40.tar.gz

wget http://nginx.org/download/nginx-1.12.1.tar.gz

程序一般安装在 /usr/local/ 目录下

安装pcre：

1、解压pcre：

# tar -zxvf pcre-8.40.tar.gz

2、进入安装包目录：

# cd pcre-8.40

3、配置、编译、安装：

# ./configure

# make

# make install

安装Nginx：

1、解压安装包：

tar -zxvf nginx-1.12.1.tar.gz

2、进入安装包目录：

# cd nginx-1.12.1

3、配置、编译、安装：

# ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/pcre-8.40
# make
# make install

注意：--with-pcre=DIR 是pcre源码目录，而不是编译安装后的目录。

4、查看Nginx版本：

# /usr/local/nginx/sbin/nginx -v

创建 Nginx 运行使用的用户 www：

# /usr/sbin/groupadd www
# /usr/sbin/useradd -g www www

配置 nginx.conf ：

参考以下：

user www;   #设置权限用户
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 {
    worker_connections  1024;
}

}

检查conf配置是否正确：

# /usr/local/nginx/sbin/nginx -t

启动Nginx：

# /usr/local/nginx/sbin/nginx

重新载入Nginx配置（平滑重启）：

# /usr/local/nginx/sbin/nginx -s reload

重启Nginx：

# /usr/local/nginx/sbin/nginx

快速关闭Nginx：

# /usr/local/nginx/sbin/nginx -s stop

正常关闭Nginx：

# /usr/local/nginx/sbin/nginx -s quit

重新打开日志文件：

# /usr/local/nginx/sbin/nginx -s reopen

加入环境变量

# vi /etc/profile.d/nginx.sh  
    
写入：export PATH=$PATH:/usr/local/nginx/sbin/  

# source /etc/profile.d/nginx.sh

---

启动：nginx  
重载：nginx -s reload  
快速停止：nginx -s stop  
有序退出：nginx -s quit
