[iyunv@HE3 ~]#groupadd mariadb -g 513

[iyunv@HE3 ~]#useradd-u 513 -g mariadb -s /sbin/nologin -d /home/mariadb mariadb

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

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

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

[iyunv@HE3 ~]#mkdir -p/data/mariadb

[iyunv@HE3 ~]#chown -Rmariadb. /data/mariadb

[iyunv@HE3 ~]#mkdir -p/log/mariadb

[iyunv@HE3 ~]#chown -Rmariadb. /log/mariadb

初始化数据库

[iyunv@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

[iyunv@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

1 2 3 4 5 6 7 8 9 10 11 12 13 14

[iyunv@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

1	311       $bindir/mysqld_safe --defaults-file=/usr/local/mariadb/my.cnf --datadir="$datadir" --pid-file="$mysqld_pid_file_path" "$@" >/dev/null 2>&1 &
