mysql的配置文件： /etc/my.cnf
mysql的日志文件： /var/log/mysql.log
140 为master
140 为master
1. 创建一个用户’repl’,并且允许其他服务器可以通过该用户远程访问master，通过该用户去读取二进制数据，实现数据同步
Create user repl identified by ‘repl； repl用户必须具有REPLICATION SLAVE权限，除此之外其他权限都不需要
GRANT REPLICATION SLAVE ON *.* TO ‘repl’@’%’ IDENTIFIED BY ‘repl’ ;
create user repl identified by ‘repl； repl用户必须具有replication slave权限，除此之外其他权限都不需要
grant replication slave on *.* to ‘repl’@’%’ identified BY ‘repl’ ;
2. 修改140 my.cnf配置文件，在[mysqld] 下添加如下配置
log-bin=mysql-bin //启用二进制日志文件
server-id=130 服务器唯一ID
3. 重启数据库 systemctl restart mysqld
3. 重启数据库 systemctl restart mysqld sudo /etc/init.d/mysql start
4. 登录到数据库，通过show master status 查看master的状态信息
142 为slave
1. 修改142 my.cnf配置文件， 在[mysqld]下增加如下配置

2. 重启数据库： systemctl restart mysqld
3. 连接到数据库客户端，通过如下命令建立同步连接
change master to master_host=’192.168.11.140’, master_port=3306,master_user=’repl’,master_password=’repl’,master_log_file=’mysql-bin.000001’,master_log_pos=0;
change master to master_log_file='mysql-bin 隆.000002',master_log_pos=154;
error:
ERROR 1794 (HY000): Slave is not configured or failed to initialize properly. You must at least set --server-id to enable either a master or a slave. Additional error messages can be found in the MySQL error log.
最后通过如下的操作解决的问题，具体原因还尚未清楚
CHANGE MASTER TO
MASTER_HOST='39.107.245.253',
MASTER_USER='repl',
MASTER_PASSWORD='repl',
MASTER_LOG_FILE='mysql-bin 隆.000001',
MASTER_LOG_POS= 154;
(1)登录数据库后，删除5张表，并重新导入脚本
use mysql
drop table slave_master_info;
drop table slave_relay_log_info;
drop table slave_worker_info;
drop table innodb_index_stats;
drop table innodb_table_stats;
---------------------
2.重启数据库
change master to master_host='39.107.245.253', master_port=3306,master_user='repl',master_password='repl',master_log_file='mysql-bin 隆.000001',master_log_pos=154;
红色部分从master的show master status可以找到对应的值，不能随便写。
4. 执行 start slave
5. show slave status\G;查看slave服务器状态，当如下两个线程状态为yes，表示主从复制配置成功
