本文主要向大家介绍了MySQL数据库之关于MySQL-MMM架构的一些报错及解决方法 ，通过具体的内容向大家展现，希望对大家学习MySQL数据库有所帮助。

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
