linux 开机自启脚本配置

项目中配置一些开机自启的软件，方便我们后期的维护。

脚本一般我这里名称起的就是  redis     nginx   rabbitmq   不加后缀了。

我们的这个脚本文件放到 /etc/init.d/ 下就可以了，

 这里上传到这里后可能还是一个普通文件，我们需要给他们添加执行权限，让他们可以被执行

chmod +x redis

chmod +x nginx 

chmod +x rabbitmq

好了权限赋予完成，我们就可以执行命令了。

接下来我们就是添加服务和启动了

chkconfig --add  redis

chkconfig --add nginx 

chkconfig --add rabbitmq

服务已经添加了我们可以来看一下

chkconfig --list

 这里有的已经开启了，所以显示的是开。123456全部关，就是没有开启了。

开启服务命令

  chkconfig redis on

好了，然后启动redis,之后看看是不是启动了

ps -ef|grep redis  查看redis进程

然后我们重启虚拟机，看看启动后是不是可以启动。

# 1.将(脚本)启动文件移动到 /etc/init.d/或者/etc/rc.d/init.d/目录下。（前者是后者的软连接）
mv test.sh /etc/rc.d/init.d
 
# 2.启动文件前面务必添加如下三行代码，否侧会提示chkconfig不支持。
#!/bin/sh             告诉系统使用的shell,所以的shell脚本都是这样
#chkconfig: 35 20 80        分别代表运行级别，启动优先权，关闭优先权，此行代码必须
#description: http server     自己随便发挥！！！，此行代码必须
/bin/echo $(/bin/date +%F_%T) >> /tmp/test.log
 
# 3.增加脚本的可执行权限
chmod +x /etc/rc.d/init.d/test.sh
 
# 4.添加脚本到开机自动启动项目中。添加到chkconfig，开机自启动。
[root@localhost ~]# cd /etc/rc.d/init.d
[root@localhost ~]# chkconfig --add test.sh
[root@localhost ~]# chkconfig test.sh on
 
# 5.关闭开机启动 
[root@localhost ~]# chkconfig test.sh off
 
# 6.从chkconfig管理中删除test.sh
[root@localhost ~]# chkconfig --del test.sh
 
# 7.查看chkconfig管理
[root@localhost ~]# chkconfig --list test.sh

粗体三条路径需要自己配置：

  1，配置文件路径

  2，服务器启动文件路径

  3，客户端启动程序的路径

这个配置文件是重宝塔安装的文件中拷贝出来的，改了该，注释的部分就是改动的，所以很好的利用上了。

2，nginx

粗体文字的四个地方：

  1，启动文件位置

  2，配置文件位置

3，rabbitmq

这里的脚本只可以使用启动停止，但是自启动，我试过还是不行，不知道哪里设置错误。网上好多的都是这个问题，可以手动使用，但是自启动就是不行，使用rpm安装后的也就是自动生成的也是这个文件，哪个拿过来

就不可以开机自启动，不知道为什么。哪位懂得可以告诉一下。上边两个我都试过了，可以使用的。

只需要改动粗体部分就可以。然后使用命令  赋权， 执行就可以

2，以服务的方式【

添加服务nginx.server

文件保存在目录下：以754的权限。目录路径：/usr/lib/systemd/system。如上面的supervisord.service文件放在这个目录下面。

[root@localhost ~]# cat /usr/lib/systemd/system/nginx.service

[root@localhost ~]# cat /usr/lib/systemd/system/supervisord.service


设置开机自启动
[root@localhost ~]# systemctl enable nginx.service    
[root@localhost ~]# systemctl enable supervisord
 
停止开机自启动
[root@localhost ~]# systemctl disable nginx.service
[root@localhost ~]# systemctl disable supervisord
 
验证一下是否为开机启动
[root@localhost ~]# systemctl is-enabled nginx
[root@localhost ~]# systemctl is-enabled supervisord
