?????

1. 1.查看系统是否已有Mariadb包
   
2. [root@localhost ~]# rpm -qa | grep mariadb
   
3. mariadb-server-5.5.52-1.el7.x86_64
   mariadb-libs-5.5.52-1.el7.x86_64
   2.删除已有安装包
   rpm -e--nodeps mariadb-server-5.5.52-1.el7.x86_64
   rpm -e--nodeps mariadb-libs-5.5.52-1.el7.x86_64
   (使用yum remove mysql mysql-server mysql-libs compat-mysql51全部删除；)
   

3.查找下载地址
http://mirrors.aliyun.com/mariadb/yum/10.1/centos/7.3/x86_64/
4.建立安装脚本
编辑内容如下
vim /etc/yum.repos.d/MariaDB.repo


[mariadb]
name = MariaDB
baseurl = http://mirrors.aliyun.com/mariadb/yum/10.1/centos/7.3/x86_64/
gpgkey =http://mirrors.aliyun.com/mariadb/yum/RPM-GPG-KEY-MariaDB
gpgcheck = 1


:wq
5.开始yum安装
yum -y install MariaDB-server MariaDB-client
6.安装完成启动Mariadb


systemctl start mariadb

7.设置开机启动

systemctl enable mariadb

8.配置Mariadb

mysql_secure_installation

根据提示设置密码
以下仅作参考
Enter current password for root (enter for none):<–初次运行直接回车
设置密码
Set root password? [Y/n] <– 是否设置root用户密码，输入y并回车或直接回车
New password: <– 设置root用户的密码
Re-enter new password: <– 再输入一次你设置的密码
其他配置
Remove anonymous users? [Y/n] <– 是否删除匿名用户，回车
Disallow root login remotely? [Y/n] <–是否禁止root远程登录,回车,
Remove test database and access to it? [Y/n] <– 是否删除test数据库，回车
Reload privilege tables now? [Y/n] <– 是否重新加载权限表，回车
初始化MariaDB完成，接下来测试登录

mysql -uroot -ppassword

9.修改配置文件
vim /etc/my.cnf

92. # To configure this host as a replication slave, you can choose between
    
93. # two methods :
    
94. #
    
95. # 1) Use the CHANGE MASTER TO command (fully described in our manual) -
    
96. # the syntax is:
    
97. #
    
98. # CHANGE MASTER TO MASTER_HOST=, MASTER_PORT=,
    
99. # MASTER_USER=, MASTER_PASSWORD= ;
    
100. #
     
101. # where you replace , , by quoted strings and
     
102. # by the master's port number (3306 by default).
     
103. #
     
104. # Example:
     
105. #
     
106. # CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
     
107. # MASTER_USER='joe', MASTER_PASSWORD='secret';
     
108. #
     
109. # OR
     
110. #
     
111. # 2) Set the variables below. However, in case you choose this method, then
     
112. # start replication for the first time (even unsuccessfully, for example
     
113. # if you mistyped the password in master-password and the slave fails to
     
114. # connect), the slave will create a master.info file, and any later
     
115. # change in this file to the variables' values below will be ignored and
     
116. # overridden by the content of the master.info file, unless you shutdown
     
117. # the slave server, delete master.info and restart the slaver server.
     
118. # For that reason, you may want to leave the lines below untouched
     
119. # (commented) and instead use CHANGE MASTER TO (see above)
     
120. #
     
121. # required unique id between 2 and 2^32 - 1
     
122. # (and different from the master)
     
123. # defaults to 2 if master-host is set
     
124. # but will not function as a slave if omitted
     
125. #server-id = 2
     
126. #
     
127. # The replication master for this slave - required
     
128. #master-host =
     
129. #
     
130. # The username the slave will use for authentication when connecting
     
131. # to the master - required
