mysl 基于 GTID主從復制

注意：如果主mysql已經跑了一段時間，需要用備份軟件把數據備份恢復到從服務器上去，確保主從服務器數據一致，否則可能報錯，而且mysql 只有5.6 以后才支持gtid，安裝時確保你的軟件支持gpid
1.安裝mysql
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm #下載mysql的yum源
yum install mysql57-community-release-el7-10.noarch.rpm -y # 安裝yum源
yum -y install mysql-community-server -y #yum 安裝mysql
2.編輯主配置文件

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
basedir=/usr/local/mysql
user=mysql
port=3306
server-id=1
gtid-mode=ON
enforce-gtid-consistency=ON
binlog_format=row
log-bin=log-bin
symbolic-links=0
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
我都是用的rpm默認路徑，實際安裝自己需求該路徑

3.編輯從文件

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
basedir=/usr/local/mysql
user=mysql
port=3306
server-id=2
gtid-mode=ON
enforce-gtid-consistency=ON
binlog_format=ROW
log-bin=log-bin
log_slave_updates=ON
skip-slave-start=1
symbolic-links=0
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

4.創建具有復制權限的賬號，在主的上面創建
grant replication slave on *.* to 'rep'@'192.168.%.%' identified by '123456';
5.從服務器配置連接
進入mysql配置
change master to master_host='192.168.1.32', master_user='rep',master_password='123456',master_port=3306,master_auto_position=1;
6.啟動同步，查看
start slave；#啟動
show slave status;

這里兩個yes 說明同步成功了
