一、agent进程
[root@master2 mysql-mmm-2.2.1]# /etc/init.d/mysql-mmm-agent start
Daemon bin: '/usr/sbin/mmm_agentd'
Daemon pid: '/var/run/mmm_agentd.pid'
Starting MMM Agent daemon... Can't locate Proc/Daemon.pm in @INC (@INC contains: /root/perl5/lib/perl5/5.16.3/x86_64-linux-thread-multi /root/perl5/lib/perl5/5.16.3 /root/perl5/lib/perl5/x86_64-linux-thread-multi /root/perl5/lib/perl5 /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/sbin/mmm_agentd line 7.
BEGIN failed--compilation aborted at /usr/sbin/mmm_agentd line 7.
failed
出现以上报错信息，可能是由于缺少环境变量导致服务启动失败。
解决方法
[root@master2 mysql-mmm-2.2.1]# cpan Proc::Daemon
[root@master2 mysql-mmm-2.2.1]# cpan Log::Log4perl
再次启动
[root@master2 mysql-mmm-2.2.1]# /etc/init.d/mysql-mmm-agent start
Daemon bin: '/usr/sbin/mmm_agentd'
Daemon pid: '/var/run/mmm_agentd.pid'
Starting MMM Agent daemon... Ok
二、监控进程
[root@monitor ~]# /etc/init.d/mysql-mmm-monitor start
Daemon bin: '/usr/sbin/mmm_mond'
Daemon pid: '/var/run/mmm_mond.pid'
Starting MMM Monitor daemon: Can't locate Proc/Daemon.pm in @INC (@INC contains: /root/perl5/lib/perl5/5.16.3/x86_64-linux-thread-multi /root/perl5/lib/perl5/5.16.3 /root/perl5/lib/perl5/x86_64-linux-thread-multi /root/perl5/lib/perl5 /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/sbin/mmm_mond line 11.
BEGIN failed--compilation aborted at /usr/sbin/mmm_mond line 11.
failed
解决方法：安装下列perl的库
[root@monitor ~]# cpan Proc::Daemon
[root@monitor ~]# cpan Log::Log4perl
再次启动
[root@monitor ~]# /etc/init.d/mysql-mmm-monitor start
Daemon bin: '/usr/sbin/mmm_mond'
Daemon pid: '/var/run/mmm_mond.pid'
Starting MMM Monitor daemon: Ok
