安装：

二进制安装包

mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz

卸载默认安装的数据库

# rpm -aq | grep mysql

# rpm -e mysql-libs-5.1.73-7.el6.x86_64

# tar xf mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz -C /opt

# cd /opt

# ln -s mysql-5.7.20-linux-glibc2.12-x86_64/ mysql

设置环境变量

echo "export PATH=/opt/mysql/bin/:\$PATH" >> /etc/profile

echo "export MYSQL_HOME=/opt/mysql" >>/etc/profile

 

# groupadd mysql

# useradd mysql -g mysql

# mkdir /data/mysql_3306/{logs,data,tmp,binlogs} -p

# chown -R mysql.mysql /data/mysql_3306/

# yum -y install numactl.x86_64

# mysqld --initialize --user=mysql --basedir=/opt/mysql --datadir=/data/mysql_3306/data/

# mysqld_safe --defaults-file=/etc/my.cnf &

注：mysql5.7的初始密码可至/data/mysql_3306/logs/error.log寻找（找寻关键字password）
