这个脚本可以实现用户自己选择想要安装的Nginx版本

比如我想装一个nginx-1.16.1版本,可以这样做:

sh install_nginx.sh install 16 1
Copy after login

当然,如果你开始并不知道使用方法,直接执行了脚本,没关系,有提示:

[root@localhost ~]# sh install_nginx.sh
使用方法
install_nginx.sh start|stop|restart|reload
安装方法
install_nginx.sh install <版本号> <小版本号>  例如:install_nginx.sh install 19 3 下载的就是1.19.3版本
Copy after login

瞧,不光告诉了你怎么使用它安装服务,还可以直接运行脚本进行管理当你刚安装完成的时候默认是启动的,你可以使用脚本进行关闭或重启:

[root@localhost ~]# sh install_nginx.sh stop
Nginx Stop successfully.
[root@localhost ~]# sh install_nginx.sh reload
Copy after login

然后你可以修改配置后进行开启:

[root@localhost ~]# sh install_nginx.sh start
root       4236      1  0 14:23 ?        00:00:00 nginx: master process /app/nginx/sbin/nginx
Nginx Start successfully.
Copy after login

查看它的状态,看它是否在运行:

[root@localhost ~]# ss -utpln | grep nginx
tcp    LISTEN     0      128       *:80                    *:*                   users:(("nginx",pid=4238,fd=6),("nginx",pid=4236,fd=6))
Copy after login
