测试环境

192.168.2.201　　master slave

192.168.2.202　　master slave

配置流程：安装MySQL->优化系统->优化配置my.cnf->初始化mysqld->添加同步用户->开始同步->查看同步状态。

1.先关闭master

2.配置 /etc/my.cnf

[mysql]
default-character-set=utf8

[mysqld]
default-storage-engine=INNODB
character_set_server=utf8
basedir=/opt/mysql
datadir=/data/mysql/data
socket=/data/mysql/mysql.sock
skip_ssl

server-id = 1                    #backup这台设置2
binlog-ignore-db = mysql,information_schema,sys      #忽略写入binlog日志的库
binlog-ignore-db = mysql
replicate-do-db = test
replicate-do-db = test2

relay_log = mysql-relay-bin
gtid-mode=on
enforce_gtid_consistency = 1
log_slave_updates =1

auto_increment_offset=1         #自增ID起始值
auto_increment_increment=2      #每次自增数字
log-bin=mysql-bin               #开启二进制功能，主服务器必须打开
max_binlog_size=1024M           #binlog单文件最大值

slave_skip_errors=1396
slave_skip_errors=all
symbolic-links=0

[mysqld_safe]
log-error=/data/mysql/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

3. 启动master

4. 创建复制账户

create user repl@'%' identified by '123456';  
grant replication slave on *.* to repl@'%' ;
flush privileges;

5.  启动slave

6.启动复制　

　　change master to master_host='192.168.2.201', master_user='repl',master_password='123456',master_auto_position=1;

　　start slave;

7. 查看状态

　　show slave status;
