Mysql5.7主從復(fù)制如何配置文檔

下面一起來(lái)了解下Mysql5.7主從復(fù)制如何配置文檔，相信大家看完肯定會(huì)受益匪淺，文字在精不在多，希望Mysql5.7主從復(fù)制如何配置文檔這篇短內(nèi)容是你想要的。

安裝的數(shù)據(jù)是mysql5.7社區(qū)版本yum安裝,官網(wǎng)有下載地址

wget https://repo.mysql.com//mysql57-community-release-el7-10.noarch.rpm

注意事項(xiàng): 防火墻,命令引號(hào).

主云服務(wù)器 

[root@localhost opt]# egrep -v "^$|#" /etc/my.cnf 紅色部分為添加

[mysqld]

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

symbolic-links=0

log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

server-id=1                      

log-bin=mysql-bin

登陸數(shù)據(jù)庫(kù)

systemctl start mysqld.service

grep 'temporary password' /var/log/mysqld.log #查看臨時(shí)密碼

mysql -uroot -p

修改root密碼

set global validate_password_policy=0;   #取消復(fù)雜密碼設(shè)置

alter user 'root'@'localhost' identified by '123';

開(kāi)始創(chuàng)建用戶

GRANT REPLICATION SLAVE ON *.* TO 'repl'@'192.168.1.%' IDENTIFIED BY 'admin123456';  

查看master日志

mysql>quit

mysql>SHOW MASTER STATUS;

+------------------+----------+--------------+------------------+-------------------+

| File         | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |

+------------------+----------+--------------+------------------+-------------------+

| mysql-bin.000001 |    154 |         |             |             |

+------------------+----------+--------------+------------------+-------------------+

1 row in set (0.00 sec)

從配置

[root@localhost ~]# egrep -v "^$|#" /etc/my.cnf

[mysqld]

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

symbolic-links=0

log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

server-id=2

登陸數(shù)據(jù)庫(kù)5.7版本

CHANGE MASTER TO  

MASTER_HOST='192.168.1.200',
MASTER_PORT=3306,

MASTER_USER='repl',  

MASTER_PASSWORD='admin123456',  

MASTER_LOG_FILE='mysql-bin.000001',  主配置日志

MASTER_LOG_POS=154;   主配置日志

啟動(dòng)

start slave;

stop slave;

查看是否連接成功. 紅色部分一定要為yes.

mysql> show slave status \G
