解决configure: error: Popt libraries is required
这个错误是因为没有安装popt的开发包导致的，解决方法也很简单，只要yum install popt-devel,就可以安装好popt的开发包了。重新./configure.
Grant replication slave,file on *.* to ‘slave’@’%’identified by ‘slave’;
Master-master 配置
Master1:192.168.2.54
nano /etc/my.cnf
| log-bin=mysql-bin server-id=1 binlog-do-db=test binlog-ignore-db=mysql replicate-do-db=test replicate-ignore-db=mysql log-slave-updates slave-skip-errors=all sync_binlog=1 auto_increment_increment=2 auto_increment_offset=1 |
master2:192.168.2.60
| log-bin=mysql-bin server-id=2 binlog-do-db=test binlog-ignore-db=mysql replicate-do-db=test replicate-ignore-db=mysql log-slave-updates slave-skip-errors=all sync_binlog=1 auto_increment_increment=2 auto_increment_offset=1 |
操作master1 ,同时作为master2的slave
change master to master_host='192.168.2.60',master_user=’slave’,master_password='slave',master_log_file='mysql-bin.000001', master_log_pos=98;
对master2 进行操作
change master to master_host='192.168.2.54',master_user=’slave’,master_password='slave',master_log_file='mysql-bin.000001', master_log_pos=98;
查看master状态 show master status\G
查看slave状态 show slave status\G
Slave stop,slave start
show processlist 查看执行状态
安装keepalived
wget http://www.keepalived.org/software/keepalived-1.2.1.tar.gz
./configure
Make&&make install
