mysql MHA安装搭建问题实验总结

问题一：
[root@mvxl0784 apps]# perl -MCPAN -e "install Config::Tiny"
CPAN: Storable loaded ok (v2.20)

Please check the validity of the index file by comparing it to more

happen.

解决方法：
[root@mvxl0784 ~]# perl -MCPAN -e shell
Terminal does not support AddHistory.

cpan> o conf urllist unshift http://www.perl.com/CPAN/
cpan> o conf commit

cpan>reload index

cpan shell -- CPAN exploration and modules installation (v1.9402)
Enter 'h' for help.

cpan[1]> reload index

  [Currently running version is v1.9402]
  You might want to try
    install CPAN
    reload cpan
  to both upgrade CPAN.pm and run the new version without leaving
  the current session.

设置完后，再查看/usr/share/perl5/CPAN/Config.pm文件中的url是否正确。

解决方法：
将以下加入/etc/profile
export PERL5LIB=/apps/lib/mha/mha_node
执行source /etc/profilemanager
重新再安装manager。

问题三：
[apps@mvxl0784 ~]$ /apps/sh/mha/mha_manager/bin/masterha_check_ssh \

解决方法：
$HOME/.bashrc加入：
export PERL5LIB=/apps/lib/mha/mha_node:/apps/lib/mha/mha_manager

问题四：

MySQL Replication Health is NOT OK

解决方法：
在配置文件上加入port=3307:
[server1]
hostname=10.16.24.107
port=3307
master_binlog_dir=/apps/dbdat/mariadb101_data3307/log
candidate_master=1

解决方法：
在/usr/local中建立一个link:
ln -s /apps/svr/mariadb101 mysql
再将/usr/local/mysql/bin增加到$HOME/.bashrc的$PATH中
