上次说到MySQL可靠性方案分析与比较,这回简单介绍下 mysql-master-master的安装,希望有使用过的兄弟多多讨论 ...

    作用: 高可用性 mysql 集群,也称不上集群,主要体现在高可用性上吧!
    原理: 在 master-master (互为 master-slave) 基础上,用 perl 写的脚本,提供虚拟IP,并实现HA

                                       cpan Time::HiRes
                                       cpan DBI
                                       cpan DBD::mysql
                                       cpan Algorithm::Diff    

         安装 DBD::mysql 可能会遇到的问题: (1).mysql_config 提示为找到. ---  加入 /usr/local/mysql/bin 到 path 里即可
                                       (2).mysql.so,类似找不到 mysql 客户端库文件,请执行:
                                                                cp /usr/local/mysql/lib/mysql/*  /usr/lib/
                                                                cp /usr/local/mysql/include/mysql/*  /usr/include/
                                                          (3). make test 时候提示拒绝访问错误:
                                                                 perl -MCPAN -e shell
                                                                 force install DBD::mysql  强制安装,跳过 make test
