以下是MariaDB官方文档说明，MariaDB如何安装在已经存在MySQL实例的主机上：

https://mariadb.com/kb/en/library/installing-mariadb-alongside-mysql/

但是如果是先安装了MariaDB，然后再安装MySQL，比如：

MariaDB的二进制程序在/opt/mysql/mariadb-10.2.8-linux-x86_64/

在/usr/local/做了一个软链接，即

ln -s /opt/mysql/mariadb-10.2.8-linux-x86_64/ mysql

具体见《MariaDB安装》的配置是一样的。

安装时注意

新的MySQL实例的配置文件，比如/etc/my3308.cnf，数据等文件设置在/data/mysql/mysql3308/{data,log,tmp}下。

做的软链接是：

ln -s /opt/mysql/mysql-5.7.19-linux-glibc2.12-x86_64/    mysql5.7

初始化MySQL时，一定要指定配置文件！！

cd /usr/local/mysql5.7

./bin/mysqld --defaults-file=/etc/my3308.cnf --initialize

初始化没有报错，但查看日志却发现有error和多个warning，见最后。

其中有一个错误：

[ERROR] Can't read from messagefile '/opt/mysql/mariadb-10.2.8-linux-x86_64/share/english/errmsg.sys'

在配置文件，加一个参数即可

[mysqld]

language = /usr/local/mysql5.7/share/english

启动

直接使用绝对路径的mysqld来启动

/usr/local/mysql5.7/bin/mysqld --defaults-file=/etc/my3308.cnf &

关闭

直接使用绝对路径的mysqladmin来关闭

/usr/local/mysql5.7/bin/mysqladmin -S /data/mysql/mysql3308/tmp/mysql3308.sock -uroot -p shutdown

扩展

可以把启动/关闭/登录数据库做成shell文件

启动

echo '/usr/local/mysql5.7/bin/mysqld --defaults-file=/etc/my3308.cnf &' > start.sh

chmod +x start.sh

关闭

echo '/usr/local/mysql5.7/bin/mysqladmin -S /data/mysql/mysql3308/tmp/mysql3308.sock -uroot -p1234567 shutdown' > stop.sh

chmod +x stop.sh

登录

echo '/usr/local/mysql5.7/bin/mysql -S /data/mysql/mysql3308/tmp/mysql3308.sock -uroot -p1234567' > login.sh

chmod +x login.sh

这样就实现了MariaDB和MySQL同一个主机上并存。

不过初始化后，错误日志记录有一些警告的信息：
