CentOS6.x安装mysql5.6

theoforce

1、系统及安装说明
    系统：CentOS6.x_x64
    mysql:社区版5.6.21,开源数据库用的最多的mysql，编译安装比较繁琐，yum安装版本比较低且默认安装的位置是/var/下，本次采用官方下载的rpm包，通过脚本自动化安装并定制数据目录到独立分区中(本次为/data目录)


2、准备安装包
  1>官方下载
    #https://dev.mysql.com/downloads/mysql/5.6.html#downloads 选择对应的版本和平台软件包：
    MySQL-shared-compat-5.6.x-1.el6.x86_64.rpm     #x就是你下的版本号以下类同
    MySQL-devel-5.6.x-1.el6.x86_64.rpm
    MySQL-shared-5.6.x-1.el6.x86_64.rpm
    MySQL-client-5.6.x-1.el6.x86_64.rpm
    MySQL-test-5.6.x-1.el6.x86_64.rpm
    MySQL-server-5.6.x-1.el6.x86_64.rpm
  2>本实验用到的包
  https://pan.baidu.com/s/1kVraS8R 密码: iybx


    包含了以下软件包：
    MySQL-shared-compat-5.6.21-1.el6.x86_64.rpm
    MySQL-devel-5.6.21-1.el6.x86_64.rpm
    MySQL-shared-5.6.21-1.el6.x86_64.rpm
    MySQL-client-5.6.21-1.el6.x86_64.rpm
    MySQL-test-5.6.21-1.el6.x86_64.rpm
    MySQL-server-5.6.21-1.el6.x86_64.rpm


3、安装
  1>如果是官方下载的请直接执行下面操作
#rpm -ivh MySQL-shared-compat-5.6.x-1.el6.x86_64.rpm       #提供基础依赖组件，需要第一个安装
#yum remove mysql-libs -y              #御载默认自带的mysql-lib
#yum install libaio -y                         #安装libiao
#rpm -ivh MySQL-devel-5.6.x-1.el6.x86_64.rpm
#rpm -ivh MySQL-shared-5.6.x-1.el6.x86_64.rpm
#rpm -ivh MySQL-client-5.6.x-1.el6.x86_64.rpm
#rpm -ivh MySQL-test-5.6.x-1.el6.x86_64.rpm
#rpm -ivh MySQL-server-5.6.x-1.el6.x86_64.rpm　　2>脚本执行

#!/bin/bash src_dir=$(pwd) cd $src_dir tar xvf mysql5.6.21.x86_64.rpms.tar.gz tar xvf mysql5.6.21.x86_64.rpms.tar cd mysql5.6.21 rpm -ivh MySQL-shared-compat-5.6.21-1.el6.x86_64.rpm yum remove mysql-libs -y yum install libaio -y rpm -ivh MySQL-devel-5.6.21-1.el6.x86_64.rpm rpm -ivh MySQL-shared-5.6.21-1.el6.x86_64.rpm rpm -ivh MySQL-client-5.6.21-1.el6.x86_64.rpm rpm -ivh MySQL-test-5.6.21-1.el6.x86_64.rpm rpm -ivh MySQL-server-5.6.21-1.el6.x86_64.rpm #service mysql start && echo "mysql5.6.21 has installes sucess!" #mysql_root_pwd=`gawk -F : '{ print $4 }' /root/.mysql_secret` #echo "A random root password has been set. You will find it in '/root/.mysql_secret'." #echo "The random root password was:'${mysql_root_pwd// }'" service mysql stop [ -d /data/mysqldb/data ] || mkdir -p /data/mysqldb/data [ -d /data/mysqldb/log ] || mkdir -p /data/mysqldb/log chown mysql.mysql /data1/mysqldb -R cd /usr/bin ./mysql_install_db --user=mysql --basedir=/usr --datadir=/data/mysqldb/data   #迁移数据目录到/data1/mysqldb/data下可自行定制 cd $src_dircp ${src_dir}/my.cnf /etc cd /var/lib mv mysql /tmp mkdir mysql chown mysql.mysql mysql service mysql start && echo "Mysql root password was empty.Please change when you login mysql." ln -s /data/mysqldb/data/mysql.sock   /var/lib/mysql/mysql.sock       #由于一些mysql工具默认到这里找mysql.sock所以做个软链[size=1em][size=1em] [size=1em][size=1em] [size=1em][size=1em]4、注意事项 [size=1em][size=1em]1>mysql服务的root密码为空，请自行修改root密码 [size=1em]或在脚本中添加以下行 在mysql迁移好目录启动后自动修改mysql root密码

    mysqladmin -u root password "123456"
