1、上传nginx文档；解压到/data目录下，并安装依赖包
tar xf nginx-1.20.1.tar.gz -C /data/
cd /data/nginx-1.20.1/ && ll
依赖关系安装，执行如下：
yum -y install zlib pcre pcre-devel openssl openssl-devel

2、自定义安装nginx

./configure --prefix=/data/nginx-1.20.1 --conf-path=/data/nginx-1.20.1/nginx.conf --error-log-path=/data/nginx-1.20.1/logs/error.log --http-log-path=/data/nginx-1.20.1/logs/access.log --with-http_stub_status_module --pid-path=/data/nginx-1.20.1/nginx.pid --without-http_rewrite_module

make && make install

3、启动nginx
（1）常规方式：

cd /usr/local/nginx
/sbin/nginx -c conf/nginx.conf

（2）编辑脚本方式：
源码编译安装nginx是没有nginx服务的，对于这种情况的解决方案有：
编辑脚本，如下示例：

vi /root/nginx_lxc
#!/bin/bashif [ "$1" = "start" ]
then
if [ -f /data/nginx-1.20.1/nginx.pid -a -s /data/nginx-1.20.1/nginx.pid ]
then
:
else
/data/nginx-1.20.1/sbin/nginx -c /data/nginx-1.20.1/nginx.conf
echo "nginx is running..."
fi
elif [ "$1" = "stop" ]
then
if [ -f /data/nginx-1.20.1/nginx.pid -a -s /data/nginx-1.20.1/nginx.pid ]
then
kill `cat /data/nginx-1.20.1/nginx.pid`
echo "nginx is killed!"
else
echo "Failed to stop nginx Unit nginx not loaded."
exit 1
fi
elif [ "$1" = "restart" ]
then
/data/nginx-1.20.1/sbin/nginx -s reload
echo "nginx is reload"
else
echo "Usage: sh $0 {start|stop|restart}"
fi

保存退出后，授执行权限：
chmod +x /root/nginx_lxc

（3）设置开机启动项方式1：
在linux6.X或centos6.X系统下设置开机启动项，在/etc/init.d目录下添加nginx的自动启动脚本，如下示例：（说明：在linux7.x或centos7.x系统下也可这样设置）

#!/bin/bash
#
# chkconfig: 2345 85 95
# description: Nginx is a World Wide Web server.
# processname: nginx
if [ "$1" = "start" ]
then
if [ -f /data/nginx-1.20.1/nginx.pid -a -s /data/nginx-1.20.1/nginx.pid ]
then
:
else
/data/nginx-1.20.1/sbin/nginx -c /data/nginx-1.20.1/nginx.conf
echo "nginx is running..."
fi
# /data/nginx-1.20.1/sbin/nginx -c /data/nginx-1.20.1/nginx.conf
# echo "nginx is running..."
elif [ "$1" = "stop" ]
then
if [ -f /data/nginx-1.20.1/nginx.pid -a -s /data/nginx-1.20.1/nginx.pid ]
then
kill `cat /data/nginx-1.20.1/nginx.pid`
echo "nginx is killed!"
else
echo "Failed to stop nginx Unit nginx not loaded."
exit 1
fi
elif [ "$1" = "restart" ]
then
/data/nginx-1.20.1/sbin/nginx -s reload
echo "nginx is reload"
else
echo "Usage: sh $0 {start|stop|restart}"
fi脚本编辑好后，添加执行权限
chmod 775 nginx

命令执行：

启动Nginx
service nginx start

停止Nginx
service nginx stop

重启Nginx
service nginx restart

最后设置开机自启动，执行：

chkconfig --add nginx

chkconfig nginx on

查询是否设置开启自启动成功，执行：
chkconfig --list nginx

（4）设置开机启动项方式2：
在linux7.x或centos7.x系统使用systemctl管理nginx服务。
说明：由于linux7系统没有抛弃chkconfig方式管理服务，这里延续上面示例中设置的启动、停止和重启路径，如未完成之前设置，可改为nginx程序路径下的启动路径。
在/usr/lib/systemd/system目录下，创建nginx.service脚本，如下示例：

[Unit]
Description=Nginx service
After=network.target[Service]
Type=forking
PIDFile=/data/nginx-1.20.1/nginx.pid
ExecStart=/etc/init.d/nginx start
ExecReload=/etc/init.d/nginx restart
ExecStop=/etc/init.d/nginx stop
PrivateTmp=true[Install]
WantedBy=multi-user.target

保存退出
设置开机启动：
systemctl enable nginx.service

其他操作
systemctl start nginx
systemctl stop nginx
systemctl status nginx.service
systemctl disable nginx
查看是否已添加开机自启动服务
systemctl list-unit-files |grep nginx

4、nginx服务及端口查看
ss -antlup |grep nginx
ps -ef |grep nginx
lsof -i :80
