Monit Apache2 重启和 Apache 状态

Monit Apache2 重启和 Apache 状态

我正在练习使用 linux/Ubuntu。

我已经在我的云服务器 (Lightsail) 上安装了 apache2。我还安装了 Monit 来监控 Apache2。监控工作正常，并且 Monit 在 Apache2 关闭时会重新启动它（我执行了 sudo /etc/init.d/apache2 stop 来测试它）。IP（在浏览器中）不可用，然后又恢复在线。

我面临的问题是，当 Monit 重新启动 apache 时，sudo /etc/init.d/apache2 状态显示服务已关闭，但 apache 正在运行（在浏览器上检查 IP）。

ubuntu@webserver:~$ sudo /etc/init.d/apache2 status

这是 sudo vim /etc/monit/monitrc 的内容：

check process apache2 with pidfile /run/apache2/apache2.pid
    start program = "/etc/init.d/apache2 restart" with timeout 15 seconds
    stop program  = "/etc/init.d/apache2 stop"

如何确保 Apache2 正确重启，以便 sudo /etc/init.d/apache2 status 显示正确的状态？

编辑1： 我的 /etc/monit/monitrc 如下所示：

  set daemon 60
  set logfile /var/log/monit.log
  set idfile /var/lib/monit/id
  set statefile /var/lib/monit/state
set mailserver localhost
  set eventqueue
      basedir /var/lib/monit/events
      slots 100

set alert [email protected]
set alert [email protected]

set httpd port 2812 and
    use address localhost
    allow localhost
    allow admin:monit

check process apache2 with pidfile /run/apache2/apache2.pid
    start program = "/etc/init.d/apache2 start" with timeout 60 seconds
    stop program  = "/etc/init.d/apache2 stop"

check process mysqld with pidfile /var/run/mysqld/mysqld.pid
    start program = "/etc/init.d/mysql start" with timeout 60 seconds
    stop program = "/etc/init.d/mysql stop"

将监控代码更改为以下内容可修复该问题：

check process apache2 with pidfile /run/apache2/apache2.pid
    start program = "/bin/systemctl start apache2.service" with timeout 15 seconds
    stop program  = "/bin/systemctl stop apache2.service"
    restart program = "/bin/systemctl restart apache2.service"
