本文是搭建的mariadb-10.0.17版本的下载地址：https://downloads.mariadb.org/interstitial/mariadb-10.0.17/source/mariadb-10.0.17.tar.gz/from/http%3A//ftp.hosteurope.de/mirror/archive.mariadb.org/?serve
master：192.168.1.166
slave：192.168.1.165
1.创建mysql普通账号，设置数据库存储数据的目录，设置权限
[root@zsxyweb3 ~]# groupadd -r mysql
[root@zsxyweb3~]# useradd -r -g mysql -s /sbin/nologin mysql
[root@zsxyweb3~]# mkdir -p /data/mydata
[root@zsxyweb3~]# chown -R mysql:mysql /data
2.安装数据库依赖软件包
[root@zsxyweb3~]# yum install -y gcc gcc-c++ make cmake ncurses ncurses libxml2 libxml2-developenssl-devel bison bison-devel ncurses-devel
3.上传mariadb包，解压，编译安装。
[root@zsxyweb3 ~]# tar zxvf mariadb-10.0.17.tar.gz
[root@zsxyweb3 mariadb-10.0.17]# cmake-DCMAKE_INSTALL_PREFIX=/app/mysql -DMYSQL_DATADIR=/data/mydata-DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STPRAGE_ENGINE=1-DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWIYH_READLINE=1 -DWIYH_SSL=system -DVITH_ZLIB=system-DWITH_LOBWRAP=0 -DMYSQL_UNIX_ADDR=/tmp/mysql.sock -DDEFAULT_CHARSET=utf8-DDEFAULT_COLLATION=utf8_general_ci
[root@zsxyweb3 mariadb-10.0.17]# make&& make install
4.复制数据库启动脚本到/etc/init.d/mysqld目录下，修改/etc/my.cnf配置文件。
[root@zsxyweb3mariadb-10.0.17]# cd /app/mysql/
[root@zsxyweb3mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysqld
[root@zsxyweb3mysql]# chmod +x /etc/rc.d/init.d/mysqld
[root@zsxyweb3mysql]# cp support-files/my-large.cnf /etc/my.cnf
5.初始化数据库，启动数据库
[root@zsxyweb3mysql]# scripts/mysql_install_db --user=mysql --datadir=/app/mysql/data
[root@zsxyweb3mysql]#mkdir log
[root@zsxyweb3mysql]#service mysqld start
6.数据库的系统变量
[root@zsxyweb3 mysql]# vim/etc/profile.d/mysqld.sh
export PATH=$PATH:/usr/local/mysql/bin
[root@zsxyweb3 mysql]# source/etc/profile.d/mysqld.sh
[root@zsxyweb3 mysql]# mysql

9.在master数据库上授权 mysql
mysql> GRANT ALL PRIVILEGES ON *.* TO'root'@'192.168.1.% IDENTIFIED BY 'passwd' WITH GRANT OPTION;
mysql>flush privileges;
mysql> show master status;
+------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB |Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000008 | 2890 | | |
+------------------+----------+--------------+------------------+
1 row in set (0.00 sec)
10.在从slave mysql
mysql>stop slave;
mysql> change master tomaster_host='192.168.1.166',master_user='root',master_password='passwd',master_log_file='mysql-bin.000008',master_log_pos=2890,master_connect_retry=5,master_heartbeat_period=2,Master_Port=3306;
mysql>flush privileges;
mysql>start slave;
mysql>show slave status\G
