Centos6.7普通用户二进制安装mariadb10

   1.root登陆建立普通用户
        groupadd -g 150 mariadb
        uaeradd -u 150 mariadb -g -c 'MySQL Server' mariadb //-c 添加描述
        password mariadb
        su mariadb
        mkdir src usr
 

 
   2.下载二进制mariadb包
        wget http://mirrors.opencas.cn/mariadb//mariadb-10.0.22/bintar-linux-x86_64/mariadb-10.0.22-linux-x86_64.tar.gz
        tar -zxvf mariadb-10.0.22-linux-x86_64.tar.gz
        mv mariadb-10.22-linux-x86_64    3306 //可以创建多实例
        cd 3306
   3.进入3306目录建立如下目录
        data数据目录已经存在
        logs存放bin-log文件
        tmp存放

   4.进入scipts目录下根据自己服务器拷贝（拷贝3306当前目录下命名my.cnf如下是实例）
[client]
port            = 3306
socket          = /home/mariadb/usr/3306/tmp/mysql.sock //sock存放问题
default-character-set=utf8  //设置字符集的时候mysql5.1中client和mysqld添加是同样参数default-character-set=utf8到5.5就变了

[mysqld]
port            = 3306
socket          = /home/mariadb/usr/3306/tmp/mysql.sock

 5.初始化数据库
    在初始化数据库之前要需要在var/log/mysqld.log touch这个文件
    su -
    touch /var/log/mysqld.log && chown -R mariadb:mariadb mysqld.log
    exit
    ./scripts/mysql_install_db --user=mariadb --datadir=/home/mariadb/usr/3306/data/ --defaults-file=/home/mariadb/usr/3306/my.cnf
 6.启动数据库
   bin/mysqld_safe --pid-file=/home/mariadb/usr/3306/data/mysql.pid --user=mariadb --datadir=/home/mariadb/usr/3306/data/  &
 7.关闭数据库
   bin/mysqladmin -uroot -p -S /home/mariadb/usr/3306/tmp/mysql.sock shutdown
 8.建立启动，关闭，root，普通用户脚本（启动关闭为例）
 vi srv3306.mysql
#!/bin/bash
