一、准备工作：
1、安装必备工具：
[root@localhost ~]# yum -y install gcc gcc-c++ autoconf automake
[root@localhost ~]# yum -y install zlib zlib-devel openssl openssl-devel pcre-devel
2、安装之前，最好检查一下是否已经安装有nginx
[root@localhost ~]# find -name nginx
[root@localhost ~]# yum remove nginx #如果安装了，先卸载
二、Nginx编译安装：
[root@localhost ~]# cd /tmp
[root@localhost tmp]# wget http://nginx.org/download/nginx-1.14.0.tar.gz
2.解压编译
[root@localhost nginx-1.14.0]# useradd nginx
[root@localhost nginx-1.14.0]# passwd nginx
[root@localhost tmp]# tar -zxvf nginx-1.14.0.tar.gz
[root@localhost tmp]# cd nginx-1.14.0
[root@localhost nginx-1.14.0]# ./configure --prefix=/usr/local/nginx
3.安装
[root@localhost nginx-1.14.0]# make && make install
4.启动、重启、关闭
[root@localhost ～]/usr/local/nginx/sbin/nginx //启动
[root@localhost ～]/usr/local/nginx/sbin -s reload //重启
[root@localhost ～]/usr/local/nginx/sbin -s stop //关闭
5.实现systemd管理nginx
[root@localhost nginx]# vim /usr/lib/systemd/system/nginx.service
[unit]
Description=nginx
After=network.target
[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s quit
PrivateTmp=true
[Install]
WantedBy=multi-user.target
三、启动nginx服务
[root@localhost nginx]# systemctl daemon-reload
[root@localhost nginx]# systemctl start nginx
[root@localhost nginx]# systemctl status nginx
● nginx.service
