一、查看当前Nginx启动状态

[root@node1 sbin]# ps -ef |grep nginx
root      39424      1  0 14:01 ?        00:00:00 nginx: master process ./nginx
nobody    39425  39424  0 14:01 ?        00:00:00 nginx: worker process
root      40313   1884  0 15:41 pts/0    00:00:00 grep --color=auto nginx

二、而配置Nginx相关服务文件

vim /usr/lib/systemd/system/nginx.service

[Unit]
Description=nginx
After=network.target
   
[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s stop
PrivateTmp=true
   
[Install]
WantedBy=multi-user.target

三 、设置nginx命令

[root@node1 sbin]# cat  ~/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
	. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin:/usr/local/nginx/sbin


export PATH
[root@node1 sbin]# source ~/.bash_profile 
[root@node1 sbin]# nginx -v
nginx version: nginx/1.18.0
[root@node1 sbin]# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

四、设置开机启动

root@node1 ~]# systemctl enable --now  nginx.service
[root@node1 ~]# ps -ef |grep nginx
root        879      1  0 16:17 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
nobody      881    879  0 16:17 ?        00:00:00 nginx: worker process
root       1738   1645  0 16:20 pts/0    00:00:00 grep --color=auto nginx
[root@node1 ~]# 

五、测试开机启动

[root@node1 ~]# systemctl status nginx
● nginx.service - nginx
   Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled; vendor preset: disabled)
   Active: active (running) since Sat 2021-05-08 16:17:54 CST; 45s ago
