masterha_check_repl报错汇总

[[email protected] ~]#masterha_check_repl --conf=/etc/masterha/app1.cnf

导致如下报错的原因主要有两类：

1.mysql的安装时用源码安装，导致mysql的目录与MHA默认的目录不一致。解决办法用ln -s做相关软连接。注：我的mysql数据库是用mysql用户安装的，MHA是用root用户安装的，如果在同一个用户下安装不知是否可以避免此类问题

2.candidate_master对应的用户权限不足导致。

解决办法：在192.168.52.130上面，vim /etc/my.cnf，在里面添加

relay-log=/home/data/mysql/binlog/mysql-relay-bin
然后重启mysql，再去重新设置slave连接。
STOP SLAVE;
RESET SLAVE;
CHANGE MASTER TOMASTER_HOST=‘192.168.52.129‘,MASTER_USER=‘repl‘,MASTER_PASSWORD=‘repl_1234‘,MASTER_LOG_FILE=‘mysql-bin.000178‘,MASTER_LOG_POS=459;
START SLAVE;
Ok，搞定了。

MySQL Replication Health is NOT OK!

[[email protected] perl]#

解决方法：

/etc/masterha/app1.cnf文件里面的参数配置，user和repl_user都是mysql账号，需要创建好，这里是只创建了repl_user而没有创建好user账号：
user=manager
password=manager_1234
repl_user=repl
repl_password=repl_1234

在mysql节点上，建立允许manager 访问数据库的“ manager manager ”账户，主要用于SHOW SLAVESTATUS,RESET SLAVE; 所以需要执行如下命令：
GRANT SUPER,RELOAD,REPLICATIONCLIENT,SELECT ON *.* TO [email protected]‘192.168.52.%‘ IDENTIFIED BY ‘manager_1234‘;

SQL Server报错汇总

1)SQL Server服务突然无法启动 问题描述:之前一直没有问题,突然某天无法启动了 解决办法:查看控制面板->管理工具->事件查看器,发现是因为登录失败而无法启动. 找到原因,就简单了,从服务中找到SQL Server的服务,右键属性,然后打开"登录"tab页,选上本地系统,就OK了. 该问题多半是因为更改了操作系统的登录密码造成了.所以要更新sqlserver的账户登录密码.当然,最好的方式就是就是上面的觪决办法了. 这样以后就会自动更新. 2)17051错误 代码
