简介：
是一个异步框架的Web服务器，也可以用作反向代理。现在常用在web服务器中，本文章介绍如何安装nginx.
- 安装gcc和g++
apt-get install build-essential- 1
apt-get install libtool- 1
- 安装pcre依赖库
apt-get install libpcre3 libpcre3-dev- 1
- 安装zlib依赖库
apt-get install zlib1g-dev- 1
- 安装openssl依赖库
apt-get install openssl
apt-get install libssl-dev // 未安装该库会报 SSL modules require the OpenSSL library.- 1
- 2
- 安装nginx
nginx的依赖库顺利安装完成后就可以正式开始安装nginx了，先去官网下载最新版本的源码包。下载地址为：nginx下载地址
下载完成后将包上传到服务器某个目录下。然后解压安装。
1、配置nginx
tar -zxvf nginx-1.14.0.tar.gz- 1
解压后可以进入目录并看目录文件：
cd nginx-1.14.0/- 1
可以看到有一个特别颜色的configure文件。该文件的功能主要是配置nginx。
在该目录下执行配置文件的命令：
./configure --prefix=/usr/local/nginx --with-http_ssl_module // 安装在local/nginx路径下 --with-http_ssl_module主要是配置https时用到，不加上这个参数的话到时启动https会找不到ssl模块- 1
–with-http_ssl_module主要是配置https时用到，不加上这个参数的话到时启动https会找不到ssl模块
2、编译nginx
make- 1
3、安装nginx
make install- 1
安装完成后，可以在我们之前配置的usr/local文件夹下看到有nginx的文件夹。
进入usr/local/nginx/conf目录下可以看到配置文件nginx.conf，往后对nginx的配置修改主要就是修改这个文件。
至此，nginx就算安装完成了。如果没进一步的需求到这里就可以结束了。
下面是对使用nginx的一些便利配置：
- 配置软连接
配置软连接后，以后启动nginx直接输入nginx即可。配置方法是直接输入命令行：
ln -s /usr/local/nginx/sbin/nginx /usr/bin/nginx - 1
配置完成后，可以试试：
可以看到10450 10451是nginx的进程。
- 配置开机启动服务
进入/etc/init.d目录下创建nginx文件。
vim nginx- 1
切换vim插入模式后粘贴如下脚本：
#!/bin/sh

粘贴完成后输入:wq保存。
单是这样配置文件还不足以开机启动，还得让文件具备运行权限。刚才创建未获得权限的文件会有颜色标注，如下图：
在创建文件的目录下输入权限命令：
chmod +x nginx- 1
然后文件就获取了运行的权限。
获得权限后还需要注册nginx的服务。
update-rc.d nginx defaults- 1
完成后就可以使用service nginx start/stop来控制nginx的启动及停止了。
附上常用命令：
service nginx start|stop|restart|reload|force-reload|status|configtest|rotate|upgrade
