1、安装依赖组件
yum install -y gcc gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel

2、 下载安装包
wget https://nginx.org/download/nginx-1.16.0.tar.gz

3、编译安装
tar zxvf nginx-1.16.0.tar.gz
cd nginx-1.16.0
./configure --prefix=/usr/local/nginx
make && make install

4、启动nginx服务
cd /usr/local/nginx/sbin
./nginx

5、验证服务是否启动成功
[root@localhost sbin]# netstat -ntlp | grep nginx
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      130245/nginx: master

6、添加nginx服务
vi /lib/systemd/system/nginx.service

文件内容：
[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*

7、使用systemd管理
pkill nginx
systemctl start nginx
systemctl status nginx
