1.新建mysql用戶
groupadd -g 701 mysql
useradd -M -g mysql mysql
2.在mysql安裝路徑下建data，log目錄，並賦予用戶權限
chown -R mysql:mysql ./data
chown -R mysql:mysql ./log
3.初始化數據庫
./bin/mysqld --initialize --user=mysql --basedir=/data/mysql-5.7.20-linux-glibc2.12-x86_64 --datadir=/data/mysql-5.7.20-linux-glibc2.12-x86_64/data
其中有一行告訴你密碼: temporary password is generated for root@localhost: eqzlq3dy6l%D
4.開啓mysql,登錄數據庫
cp /data/mysql-5.7.20-linux-glibc2.12-x86_64/support-files/mysql.server /etc/init.d/mysqld
service mysqld start
./bin/mysql -uroot -p eqzlq3dy6l%D
5.修改密碼
alter user 'root'@'localhost' identified by 'iec61850';
6.開放遠程登錄
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'iec61850' WITH GRANT OPTION;
FLUSH PRIVILEGES;
