server-id=6
log-bin=mysql-bin

2 重启mysql 登陆并授权

mysql -uroot -p123456

grant replication slave, replication client on *.* to 'repl'@'10.211.55.7' identified by '123456';

ip地址为slave服务器的ip地址

3 查看日志状态

show master status;

Master2 配置

1 开启binlog日志功能

vim /etc/my.cnf

server-id=8
log-bin=mysql-bin

2 重启mysql 登陆并授权

mysql -uroot -p123456

grant replication slave, replication client on *.* to 'repl'@'10.211.55.7' identified by '123456';

ip地址为slave服务器的ip地址

3 查看日志状态

show master status;

Slave 配置

1 修改配置文件 (注意 slave的默认数据库启动的端口必须关闭 service mysql stop)

vim /etc/my.cnf

[mysqld]
 binlog-ignore-db=mysql
 binlog_format=mixed
 expire_logs_days=7
 slave_skip_errors=1062
 relay_log=mysql-relay-bin
 log_slave_updates=1

[mysqld_muliti]
 mysqld=/usr/bin/mysqld_safe
 mysqladmin=/usr/bin/mysqladmin
 user=root
 password=123456
[mysqld6]
 port=3306
 datadir=/home/mysql/data6
 pid-file=/home/mysql/data6/mysql.pid
 socket=/home/mysql/data6/mysql.sock
 user=mysql
 server-id=7
[mysqld8]
 port=3307
 datadir=/home/mysql/data8
 pid-file=/home/mysql/data8/mysql.pid
 socket=/home/mysql/data8/mysql.sock
 user=mysql
 server-id=7

2 初始化生成目录

/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/home/mysql/data6 &
/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/home/mysql/data8 &

3 修改目录权限

chown -R mysql /home/mysql/data6

chown -R mysql /home/mysql/data8

4 启动服务

mysqld_multi --defaults-file=/etc/my.cnf start 6

mysqld_multi --defaults-file=/etc/my.cnf start 8

5 登录测试（并分别做授权）

mysql -P 3306 -S /home/mysql/data6/mysql.sock

mysql> change master to master_host='10.211.55.6', master_user='repl', master_password='123456', master_port=3306, master_log_file='mysql-bin.000001', master_log_pos=120;
mysql> start slave;

mysql -P 3307 -S /home/mysql/data8/mysql.sock

mysql> change master to master_host='10.211.55.8', master_user='repl', master_password='123456', master_port=3306, master_log_file='mysql-bin.000001', master_log_pos=120;
mysql> start slave;

ok 就这样 完成了
