1.在兩臺充當數據庫服務器上安裝mysql並建立主從，添加授權賬戶
1）yum安裝mysql數據庫
[root@localhost ~]# yum install mariadb mariadb-server -y2)修改master數據庫配置文件
[root@localhost ~]# vim /etc/my.cnf
[mysqld]
server_id=1 #主id號
log_bin=/data/binlog/bin #開啓二進制日誌記錄並指定保存路徑
innodb_file_per_table #每個表保存在單個文件
datadir=/var/lib/mysql #數據可路徑
socket=/var/lib/mysql/mysql.sock #套接字路徑
……3）開啓主服務數據庫並添加授權用戶
[root@localhost ~]# systemctl start mariadb
[root@localhost ~]# mysql -uroot -h127.0.0.1
添加從服務授權用戶：
MariaDB [(none)]> grant replication slave on *.* to user1@'192.168.1.106' identified by '123456';
創建wordpress專用數據庫:
MariaDB [(none)]> create database boss;
添加wordpress授權用戶:
MariaDB [(none)]> grant all on boss.* to boss@'192.168.1.%' identified by '123456';4)修改從服務數據庫配置文件
[mysqld]
server_id=2 #從服務的id號
read_only #只讀模式不允許修改數據內容
innodb_file_per_table
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
…..5）開啓從mysql數據庫並添加主從關係
[root@localhost ~]# systemctl start mariadb
[root@localhost ~]# msyql
MariaDB [(none)]> change master to
master_host='192.168.1.9',
master_user='user1',
master_password='123456',
master_log_file='bin.000005',
master_log_pos=245;
MariaDB [(none)]> start slave；#開啓從服務
MariaDB [(none)]>show slave status\G; #查看主從建立狀態
lave_IO_State: Waiting for master to send event
Master_Host: 192.168.1.9
Master_User: user1
Master_Port: 3306
Connect_Retry: 60
Master_Log_File: bin.000007
Read_Master_Log_Pos: 245
