（ mariadb配置都和mysql一模一样，完全兼容mysql）
Master：192.168.77.73 Slave：192.168.77.74
注：全程命令尽量手动敲，复制黏贴，可能出现标点符号不匹配而报错
1、安装 yum install mariadb mariadb-server -y 启动：systemctl start mariadb 端口：3306
2、配置master，配置文件如下
vim /etc/my.cnf 新增三段命令（加粗）
[code]
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd
server-id=1 #masterid为1，slaveid为2
log-bin=mysql-bin #开启binlog日志，该日志很重要
[/code]
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
replicate-do-db = discuz #确认同步的数据库名称
#
# include all files from the config directory
#
!includedir /etc/my.cnf.d
3、配置slave，配置文件如下
vim /etc/my.cnf 新增一段（加粗）
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd
server-id=2 #masterid为1，slaveid为2
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
#
# include all files from the config directory
#
!includedir /etc/my.cnf.d
4、在Master数据库服务器上设置权限并创建discuz数据库
mysql #进入数据库进行操作
create database discuz; #创建一个做主从的discuz库
grant all on *.* to root@’%’ identified by ‘123456’ ; #给一个能全能的账户备用
grant replication slave on *.* to discuz@’%’ identified by ‘123456’ ; # 授权discuz用户可以有 replication slave权限
show master status; #查看master状态，开启了binlog日志之后这个才会有下面的显示↓
+——————+———-+————–+——————+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+——————+———-+————–+——————+
| mysql-bin.000001| 474 | | |
+——————+———-+————–+——————+
5、在slave服务器指定master IP和同步的pos点等信息，创建discuz数据库，并把master上面的库导入进来
mysqldump -h192.168.77.73 -uroot -p123456 discuz > 1.sql #备份master上面的discuz库
mysql discuz < 1.sql #将备份好的库，导入到slave上面
mysql #进入数据库进行操作
change master to master_host=’192.168.77.73′,master_user=’discuz’,master_password=’123456′,master_log_file=’mysql-bin.000001′,master_log_pos=474; #指定master 信息
slave start； #开启slave
show slave status\G； #查看slave的状态，显示如下则成功↓
#Slave_IO_Running: Yes
#Slave_SQL_Running: Yes
主从配置完成！
