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

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';
