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 -y groupinstall "Development tools"
yum -y install ncurses ncurses-devel openssl-devel bison gcc gcc-c++ make

解压mysql二进制安装包:

tar -zxvf mysql-5.7.19.tar.gz -C /usr/local/mysql

编辑my3306.cnf

vim /etc/my3306.cnf

创建mysql用户

useradd mysql

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 -R mysql:mysql /home/mysql3306
chown -R mysql: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

export PATH=$PATH:/usr/local/mysql/bin

进入mysql

mysql -S /tmp/mysql3306.sock

修改mysql用户密码

mysql>UPDATE user SET authentication_string=password('root123') WHERE User='root' AND Host='localhost';
