一、环境准备
1）CentOS Linux release 7.4.1708 (Core)
2）YUM安装 Mariadb
3）两台虚拟机，master：192.168.231.132 slave：192.168.231.135
二、安装部署
1）Master 主机配置：
首先，登录到主服务器：
[root@master ~]# rpm -qa |grep mariadb
mariadb-server-5.5.56-2.el7.x86_64
mariadb-5.5.56-2.el7.x86_64
mariadb-devel-5.5.56-2.el7.x86_64
mariadb-libs-5.5.56-2.el7.x86_64
[root@master ~]# mysql -uroot -p
Enter password:
---------------------------------------
MariaDB [(none)]> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| release_system |
+--------------------+
4 rows in set (0.00 sec) #此时看到主服务器里有一个release_system库，现在退出mariadb
[root@master ~]# vim /etc/my.cnf #增加以下红色字段
[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
log-bin=mysql-bin #将mysql二进制日志取名为mysql-bin
binlog_format=mixed #二进制日志的格式，有三种：statement/row/mixed,具体分别不多做解释，这里使用mixed
server-id=1 #为服务器设置一个独一无二的id便于区分
[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
重启 mariadb 服务:
[root@master ~]# systemctl restart mariadb
进到 mariadb 界面：
MariaDB [(none)]> GRANT replication slave ON *.* TO 'biezz'@'%' IDENTIFIED BY 'biezz';
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> show master status; #查看主服务器BIN日志的信息
+------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000001 | 462 | | |
+------------------+----------+--------------+------------------+
1 row in set (0.00 sec)
2）slave 主机配置
登录到从服务器：
[root@slave ~]# rpm -qa |grep mariadb
mariadb-libs-5.5.56-2.el7.x86_64
此时，我们发现从服务器上面没有按照 mariadb，下面我们YUM安装过一遍
[root@slave ~]# yum install -y mariadb-server mariadb
