CentOS上的Monit导致无法创建httpd.pid

解决方案是替换这一行:

check process apache with pidfile /var/run/httpd.pid

有了这条线:

check process httpd with pidfile /var/run/httpd/httpd.pid

我还删除了'组apache'.

原帖:

在CentOS上安装Monit并为Apache(httpd)服务设置警报后,该服务不再创建/var/run/httpd.pid文件.

httpd服务IS正常运行.

最重要的是,好像这还不够,Monit将服务状态报告为:执行失败

当然,重启这种服务的唯一方法就是杀死它,因为'restart'脚本看不到任何正在运行的进程.

这些是/etc/monit.d/monitrc文件的内容:

set daemon  10
set logfile syslog facility log_daemon
set mailserver localhost
set mail-format { from: me@server.com }
set alert bugs@server.com
set httpd port 2812 and
#     SSL ENABLE
#     PEMFILE  /var/certs/monit.pem
allow user:password

check process apache with pidfile /var/run/httpd.pid
group apache
start program = "/etc/init.d/httpd start"
stop program  = "/etc/init.d/httpd stop"
if cpu is greater than 180% for 1 cycles then alert
if totalmem > 1200 MB for 2 cycles then restart
if children > 250 then restart

check process sshd with pidfile /var/run/sshd.pid
start program "/etc/init.d/sshd start"
stop program "/etc/init.d/sshd stop"
if failed port 22 protocol ssh for 5 cycles then restart
if 5 restarts within 25 cycles then timeout

输出"service httpd restart":

Stopping httpd:                                            [FAILED]
Starting httpd: (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80

Unable to open logs
                                                       [FAILED]

任何帮助将不胜感激.

尝试用/usr/sbin/httpd -k stop.替换停止程序.它对我有用.
