MariaDB与MySQL在一台服务器同时运行

[root@HE3 ~]#groupadd mariadb -g 513

[root@HE3 ~]#useradd-u 513 -gmariadb -s /sbin/nologin -d /home/mariadbmariadb

从MariaDB官网下载二进制安装包至/root目录,本文采用的是目前最新稳定版mariadb-10.1.16

[root@HE3 ~]# tarxvf mariadb-10.1.16-linux-x86_64.tar.gz

[root@HE3 ~]# mv/root/mariadb-10.1.16-linux-x86_64 /usr/local/mariadb

初始化数据库

[root@HE3 ~]#/usr/local/mariadb/scripts/mysql_install_db--basedir=/usr/local/mariadb --datadir=/data/mariadb--defaults-file=/usr/local/mariadb/my.cnf --user=mariadb

拷贝启停模板至/etc/init.d/下

[root@HE3 ~]#cp -rp /usr/local/mariadb/support-files/mysql.server /etc/init.d/mariadb

编辑该启停脚本变更第46、47、58行为mariadb相关目录,本文示例如下

[root@HE3 ~]#vi /etc/init.d/mariadb
     46 basedir=/usr/local/mariadb
     47 datadir=/data/mariadb
     48 
     49 # Default value, in seconds, afterwhich the script should timeout waiting
     50 # for server start.
     51 # Value here is overriden by value in my.cnf.
     52 # 0 means don't wait at all
     53 # Negative numbers mean to wait indefinitely
     54 service_startup_timeout=900
     55 
     56 # Lock directory for RedHat / SuSE.
     57 lockdir='/var/lock/subsys'
     58 lock_file_path="$lockdir/mariadb"
第311行添加唯一参数路径,本文为--defaults-file=/usr/local/mariadb/my.cnf
$bindir/mysqld_safe --defaults-file=/usr/local/mariadb/my.cnf --datadir="$datadir" --pid-file="$mysqld_pid_file_path" "$@" >/dev/null 2>&1 &

也可以手动启停

启动命令

[root@HE3~]# /usr/local/mariadb/bin/mysqld_safe --defaults-file=/etc/mariadb.cnf--ledir=/usr/local/mariadb/bin --datadir=/data/mariadb&

 停止命令

[root@HE3 ~]#/usr/local/mariadb/bin/mysqladmin --defaults-file=/usr/local/mariadb/my.cnf-hlocalhost -P3307 shutdown
