# 设置自启动服务(方式一)

注：本方式适合Centos6、7、8版本

# 第一步：编写启动脚本

vi /etc/init.d/nginx
1
点击查看启动文件样例 
#!/bin/bash
# chkconfig: 2345 58 74
# description: nginx web server
# processname: nginx
# config: /data/nginx/conf/nginx.conf
# pidfile: /data/nginx/log/nginx.pid
case $1 in
        start)
                rm -rf /dev/shm/proxy_cache_path
                /data/nginx/sbin/nginx
                ;;
        stop)
                /data/nginx/sbin/nginx -s stop
                ;;
        restart)

# 第二步 设置 nginx 为自启动服务

chmod +x /etc/init.d/nginx
chkconfig --add nginx
chkconfig nginx on
systemctl enable nginx

# 设置自启动服务(方式2)

注：本方式适合Centos8、9版本

# 第一步：创建启动服务脚本

在nginx目录(例如：/data/nginx/) 创建启动服务的脚本start.sh

vi /data/nginx/start.sh
1
点击查看start.sh内容

#!/bin/bash

/data/nginx/sbin/nginx

exit 0

# 第二步：创建停止服务脚本

在nginx目录(例如：/data/nginx/) 创建停止服务的脚本stop.sh

vi /data/nginx/stop.sh
1
点击查看stop.sh内容

#!/bin/bash

/data/nginx/sbin/nginx -s stop

# 第三步：赋予权限

分别赋予start.sh 和 stop.sh 执行权限

chmod +x /data/nginx/start.sh
chmod +x /data/nginx/stop.sh
1

# 第四步：创建service脚本

vi /lib/systemd/system/nginx.service
1
点击查看nginx.service内容 
[Unit]
Description=nginx  
After=network.target
[Service]
Type = forking
ExecStart = /data/nginx/start.sh
ExecStop = /data/nginx/stop.sh
[Install]
WantedBy = multi-user.target

# 设置权限

chmod 754 /lib/systemd/system/nginx.service


### 第五步：启动或停止服务
```shell script
# 启动服务 
systemctl start nginx.service
# 关闭服务   
systemctl stop nginx.service

如果发现启动错误，修改启动脚本后需重新加载

systemctl daemon-reload

# 第六步：设置为自启动服务

systemctl enable nginx.service
