[root@hlt1 app]# /etc/init.d/kkmail_app start authenticator: started rulefilter: started receiver: started dispatcher: started sizequerier: started proxy_monitor: start failure exit_code= 1
查看进程监控服务，发现有几个进程启动不起来。
[root@hlt1 app]# /usr/local/kkmail/app/engine/bin/supervisorctl -c /usr/local/kkmail/app/conf/supervisord.ini authenticator STOPPED Not started dispatcher STOPPED Not started ldap_monitor FATAL Exited too quickly (process log may have details) operation RUNNING pid 26746, uptime 0:00:12 proxy_monitor STOPPED Not started receiver STOPPED Not started rulefilter STOPPED Not started search_manager BACKOFF Exited too quickly (process log may have details) service_listener FATAL Exited too quickly (process log may have details) sizequerier STOPPED Not started smtp_monitor FATAL Exited too quickly (process log may have details) task_monitor FATAL Exited too quickly (process log may have details) kkmail_clamd STARTING kkmail> restart all kkmail_clamd: stopped operation: stopped sizequerier: started authenticator: started rulefilter: started receiver: started dispatcher: started ldap_monitor: ERROR (abnormal termination) proxy_monitor: ERROR (abnormal termination) service_listener: ERROR (abnormal termination) operation: started smtp_monitor: ERROR (abnormal termination) task_monitor: ERROR (abnormal termination) search_manager: ERROR (abnormal termination) kkmail_clamd: started kkmail> exit
备注：
我刚开始好像打不开，报错如下：
Error: Another program is already listening on a port that one of our HTTP servers is configured to use. Shut this program down first before starting supervisord.
For help, use /usr/local/kkmail/app/engine/bin/supervisord -h
然后我ps -ef |grep supervisord，然后kill -9 id后，运行这个命令好了/usr/local/kkmail/app/engine/bin/supervisord -c /usr/local/kkmail/app/conf/supervisord.ini
3、想知道为什么启动不了，先开启下日志看看：
[root@hlt1 store]# cat /usr/local/kkmail/app/conf/supervisord.conf.d/proxy_monitor.ini ; proxy_monitor ; [program:proxy_monitor] command=/usr/local/kkmail/app/exec/proxy_monitor autostart=false autorestart=true startsecs=0 user=kkmail stdout_logfile=NONE stdout_logfile=/usr/local/kkmail/app/log/proxy_monitor.log #把这行开启 ;stdout_logfile_maxbytes=50MB ;stdout_logfile_backups=5 stderr_logfile=NONE stderr_logfile=/usr/local/kkmail/app/log/proxy_monitor.err #把这行开启 ;stderr_logfile_maxbytes=50MB ;stderr_logfile_backups=5
[root@hlt1 store]# cat /usr/local/kkmail/app/log/proxy_monitor.log

4、看上面报错好像是redis没启动成功造成的，然后依次把mysql、app重启下，重启后再到supervisor重启所有进程。

5、虽然解决了这些问题，但是重启服务器发现redis服务依然不能开机启动，还有apache服务。redis启动不起来就造成app启动不了，app启动不起来就造成挂载失败。
后来我把/etc/ha.d/haresources文件只留kkmail_nginx服务后，重启服务器就可以挂载了。然后手动启动app和mysqld。
6、两台服务器都升级到最新版本，并且停止ha服务来回测试OK。
redis服务开机启动过异常，造成haresources里面的服务挂载失败（非法关机造成的）
