给6.30与6.32搭建主主配置的步骤如下：
IP:10.200.6.30
IP:10.200.6.32
主主配置步骤：
IP:10.200.6.30
[root@localhost ~]# vi /etc/my.cnf
log-bin=mysql-bin
server-id =1
replicate-ignore-db=mysql
replicate-ignore-db=test
replicate-ignore-db=information_schema
replicate-ignore-db=performance_schema
slave-skip-errors=all
sync_binlog=1
auto_increment_increment=2
auto_increment_offset=1
IP:10.200.6.32
log-bin=mysql-bin
server-id =2
#binlog-ignore-db=test
replicate-ignore-db=mysql
replicate-ignore-db=test
replicate-ignore-db=information_schema
replicate-ignore-db=performance_schema
log-slave-updates
slave-skip-errors=all
sync_binlog=1
auto_increment_increment=2
auto_increment_offset=2
然后分别重启两个mysqld的服务。
2. 授权用户
