1. 環境html
操做系統:CentOS-7mysql
MySQL:mysql-5.6sql
一臺虛擬機又克隆了兩臺數據庫
192.168.102.31 masteride
192.168.102.56 slavespa
192.168.102.36 slave操作系統
啓動/中止rest
service mysqld start|stop|restart systemctl start|stop|restart mysqld
本機的話,直接mysql就能夠進去了
2. 主數據庫配置code
第1步:編輯/etc/my.cnf文件,在[mysqld]下增長以下兩行設置:server
[mysqld]
log-bin=mysql-bin # 非必需
server-id=1 # 必需
第2步:建立用於數據同步的帳戶
CREATE USER 'repl'@'192.168.102.%' IDENTIFIED BY '123456'; GRANT REPLICATION SLAVE ON *.* TO 'repl'@'192.168.102.%'; FLUSH PRIVILEGES;
第3步:查看master狀態
show master status;
3. 從數據庫配置
第1步:編輯/etc/my.cnf文件,設置server-id
[mysqld]
server-id=2
第2步:執行同步語句,並啓動slave
change master to master_host='192.168.102.31', master_user='repl', master_password='123456', master_log_file='mysql-bin.000001', master_log_pos=514;
第3步:查看slave狀態
show slave status\G;
另一臺從數據庫也是這樣設置
4. 驗證是否同步成功
在主數據上操做,從數據庫中查看
5. 設置只讀帳戶
mysql> create user 'pig'@'%' identified by '123456'; mysql> grant select on test.* to 'pig'@'%'; mysql> flush privileges;
