在这里今天给大家推荐一个博文地址：http://sumongodb.blog.51cto.com/

好了！废话少说，干活走起来！！！！！！！！

CentOs6.5下MysqL5.7.19二进制安装是我自己编译的官方源码包

首先我们把一些依赖包安装上：

yum-ygroupinstall"Developmenttools"
yum-yinstallncursesncurses-developenssl-develbisongccgcc-c++make

解压MysqL二进制安装包：

tar-zxvfMysqL-5.7.19.tar.gz-C/usr/local/MysqL

编辑my3306.cnf

vim/etc/my3306.cnf

创建MysqL用户

useraddMysqL

创建MysqL相关数据目录

mkdir-p/home/MysqL3306/msyql3306
mkdit-p/home/MysqL3306/logs

给MysqL相关目录进行授权

chown-RMysqL:MysqL/home/MysqL3306
chown-RMysqL:MysqL/usr/local/MysqL

初始化MysqL

/usr/local/MysqL/bin/MysqLd--defaults-file=/etc/my3306.cnf--initialize-insecure--explicit_defaults_for_timestamp--basedir=/usr/local/MysqL--datadir=/home/MysqL3306/MysqL3306/--user=MysqL

启动MysqL

/usr/local/MysqL/bin/MysqLd_safe--defaults-file=/etc/my3306.cnf--datadir=/home/MysqL3306/MysqL3306/--user=MysqL&

配置环境变量

vim/etc/profile

exportPATH=$PATH:/usr/local/MysqL/bin

进入MysqL

MysqL-S/tmp/MysqL3306.sock

修改MysqL用户密码

MysqL>UPDATEuserSETauthentication_string=password('root123')WHEREUser='root'ANDHost='localhost';
