一、实验环境：
系统：CentOS7.6，关闭了防火墙与SELINUX
数据库版本：mariadb-10.2.25(二进制安装与源码安装)
二、安装方法：
1、yum源安装
(1) 配置yum源，官方yum源下载太慢，用国内的镜像源吧
[[email protected] ~]# cat /etc/yum.repos.d/mariadb.repo # MariaDB 10.2 CentOS repository list - created 2019-11-29 02:18 UTC # http://downloads.mariadb.org/mariadb/repositories/ [mariadb] name = MariaDB baseurl = https://mirrors.tuna.tsinghua.edu.cn/mariadb/yum/10.2/centos7-amd64/ gpgcheck=0
(2) 开始安装
[[email protected] ~]# yum install -y MariaDB-server MariaDB-client
(3) 启动服务
[[email protected] ~]# systemctl start mariadb [[email protected] ~]# ss -nlt State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 *:111 *:* LISTEN 0 128 *:6000 *:* LISTEN 0 5 192.168.122.1:53 *:* LISTEN 0 128 *:22 *:* LISTEN 0 128 127.0.0.1:631 *:* LISTEN 0 100 127.0.0.1:25 *:* LISTEN 0 80 :::3306 :::* LISTEN 0 128 :::111 :::* LISTEN 0 128 :::6000 :::* LISTEN 0 128 :::22 :::* LISTEN 0 128 ::1:631 :::* LISTEN 0 100 ::1:25 :::* [[email protected] ~]# mysql Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 8 Server version: 10.2.29-MariaDB MariaDB Server Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement. MariaDB [(none)]>
(4) 设置mysql密码，可以用/usr/bin/mysqladmin -u root password ‘new-password‘ 设置，或使用安全脚本设置，以下为用脚本设置
[[email protected] ~]# /usr/bin/mysql_secure_installation
#使用脚本交互式设置
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we‘ll need the current
password for the root user. If you‘ve just installed MariaDB, and
you haven‘t set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from ‘localhost‘. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] y
... Success!
By default, MariaDB comes with a database named ‘test‘ that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... Success!
Cleaning up...
All done! If you‘ve completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
2、源码安装
(1) 先下载文件到服务器

(5) 安装完成后，配置环境变量
[[email protected] mariadb-10.2.25]# echo ‘PATH=/app/mysql/bin:$PATH‘ > /etc/profile.d/mysql.sh [[email protected] mariadb-10.2.25]# . /etc/profile.d/mysql.sh [[email protected] mariadb-10.2.25]# echo $PATH /app/mysql/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
(6) 初始化数据库，生成数据库文件
[[email protected] bin]# cd /app/mysql/ [[email protected] mysql]# scripts/mysql_install_db --datadir=/data/mysql --user=mysql Installing MariaDB/MySQL system tables in ‘/data/mysql‘ ... OK To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER ! To do so, start the server, then issue the following commands: ‘./bin/mysqladmin‘ -u root password ‘new-password‘ ‘./bin/mysqladmin‘ -u root -h centos7.localdomain password ‘new-password‘ Alternatively you can run: ‘./bin/mysql_secure_installation‘ which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers. See the MariaDB Knowledgebase at http://mariadb.com/kb or the MySQL manual for more instructions. You can start the MariaDB daemon with: cd ‘.‘ ; ./bin/mysqld_safe --datadir=‘/data/mysql‘ You can test the MariaDB daemon with mysql-test-run.pl cd ‘./mysql-test‘ ; perl mysql-test-run.pl Please report any problems at http://mariadb.org/jira The latest information about MariaDB is available at http://mariadb.org/. You can find additional information about the MySQL part at: http://dev.mysql.com Consider joining MariaDB‘s strong and vibrant community: https://mariadb.org/get-involved/
(7) 准备配置文件与启动脚本
[[email protected] mysql]# cp /app/mysql/support-files/my-huge.cnf /etc/my.cnf [[email protected] mysql]# cp /app/mysql/support-files/mysql.server /etc/init.d/mysqld

(3) 准备二进制程序
[[email protected] ~]# tar -zxvf mariadb-10.2.25-linux-x86_64.tar.gz -C /usr/local [[email protected] ~]# cd /usr/local/ [[email protected] local]# ln -sv mariadb-10.2.25-linux-x86_64 mysql ‘mysql’ -> ‘mariadb-10.2.25-linux-x86_64’ [[email protected] local]# chown -R root:mysql /usr/local/mysql/
(4) 准备配置文件
[[email protected] mysql]# mkdir /etc/mysql [[email protected] mysql]# cp support-files/my-large.cnf /etc/mysql/my.cnf [[email protected] mysql]# vim /etc/mysql/my.cnf #在[mysqld]中添加下面三个选项： datadir = /data/mysql innodb_file_per_table = on skip_name_resolve = on #禁止主机名解析，建议使用
(5) 初始化数据库，生成数据库文件
[[email protected] ~]# cd /usr/local/mysql [[email protected] mysql]# ./scripts/mysql_install_db --datadir=/data/mysql --user=mysql Installing MariaDB/MySQL system tables in ‘/data/mysql‘ ... 2019-11-29 13:53:32 140116365457216 [Warning] ‘THREAD_CONCURRENCY‘ is deprecated and will be removed in a future release. 2019-11-29 13:53:33 140116364871424 [Warning] Failed to load slave replication state from table mysql.gtid_slave_pos: 1146: Table ‘mysql.gtid_slave_pos‘ doesn‘t exist OK To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER ! To do so, start the server, then issue the following commands: ‘./bin/mysqladmin‘ -u root password ‘new-password‘ ‘./bin/mysqladmin‘ -u root -h centos7.localdomain password ‘new-password‘ Alternatively you can run: ‘./bin/mysql_secure_installation‘ which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers. See the MariaDB Knowledgebase at http://mariadb.com/kb or the MySQL manual for more instructions. You can start the MariaDB daemon with: cd ‘.‘ ; ./bin/mysqld_safe --datadir=‘/data/mysql‘ You can test the MariaDB daemon with mysql-test-run.pl cd ‘./mysql-test‘ ; perl mysql-test-run.pl Please report any problems at http://mariadb.org/jira The latest information about MariaDB is available at http://mariadb.org/. You can find additional information about the MySQL part at: http://dev.mysql.com Consider joining MariaDB‘s strong and vibrant community: https://mariadb.org/get-involved/
(6) 准备服务脚本，并启动服务

(5) 准备启动服务脚本
[[email protected] mysql]# cd /mysql/3306/bin/
[[email protected] bin]# vim mysqld
[[email protected] bin]# cat mysqld
#!/bin/bash
port=3306 #端口号记得要改
mysql_user="root" #数据库用户名
mysql_pwd="" #数据库密码，因初始化时是没有密码的，此外先为空，后续记得改
cmd_path="/usr/local/mysql/bin" #命令路径
mysql_basedir="/mysql"
mysql_sock="${mysql_basedir}/${port}/socket/mysql.sock"
function_start_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "Starting MySQL...\n"
${cmd_path}/mysqld_safe --defaults-file=${mysql_basedir}/${port}/etc/my.cnf &> /dev/null &
else
printf "MySQL is running...\n"
exit
fi
}
function_stop_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "MySQL is stopped...\n"
exit
else
printf "Stoping MySQL...\n"
${cmd_path}/mysqladmin -u ${mysql_user} -p${mysql_pwd} -S ${mysql_sock} shutdown
fi
}
function_restart_mysql()
{
printf "Restarting MySQL...\n"
function_stop_mysql
sleep 2
function_start_mysql
}
case $1 in
start)
function_start_mysql
;;
stop)
function_stop_mysql
;;
restart)
function_restart_mysql
;;
*)
printf "Usage: ${mysql_basedir}/${port}/bin/mysqld {start|stop|restart}\n"
esac
[[email protected] bin]# cp mysqld /mysql/3307/bin/
[[email protected] bin]# cp mysqld /mysql/3308/bin/
[[email protected] bin]# sed -i ‘s/3306/3307/g‘ /mysql/3307/bin/mysqld

[[email protected] bin]# ss -nlt | grep 330*
LISTEN 0 80 :::3306 :::*
LISTEN 0 80 :::3307 :::*
LISTEN 0 80 :::3308 :::*
(6) 配置PATH变量，使用mysql客户端测试
[[email protected] bin]# cd /usr/local/mysql/ [[email protected] mysql]# echo ‘PATH=/usr/local/mysql/bin:$PATH‘ > /etc/profile.d/mysql.sh [[email protected] mysql]# . /etc/profile.d/mysql.sh #使用不同端口socket文件连接不同的实例 [[email protected] mysql]# mysql -S /mysql/3306/socket/mysql.sock Welcome to the MariaDB monitor.
