初始化mysql

/usr/local/mysql/bin/mysqld –initialize-insecure –user=mysql –basedir=/usr/local/mysql –datadir=/data/mysql

添加MySQL环境变量

echo “export PATH=/usr/local/mysql/bin:$PATH” >> /etc/profile
source /etc/profile

导出头文件

ln -sv /usr/local/mysql/include /usr/include/mysqld

导出库文件

echo “/usr/local/mysql/lib” > /etc/ld.so.conf.d/mysql.conf
ldconfig

添加启动脚本

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig –add mysqld

启动服务,启动服务之后可以直接无码密码登录,如果无法登录继续下面两步

/etc/init.d/mysqld start

找到mysql5.7的初始密码

grep “temporary password” /data/mysql/mysql-error.log
