sql mysql pass 查看 連接 var 客戶 l數據庫 sql skip
1、先查看是否有安裝mysql,有的話通過yum remove mysql先卸載掉,卸載完成後執行
yum install -y mysql-server mysql mysql-deve
2、啟動mysql服務
service mysqld start //也可以通過/etc/init.d/mysqld start啟動
3、設置為開機自啟動
chkconfig mysqld on
4、設置root賬號的密碼
mysqladmin -u root password ‘newpass‘
如果上面這種設置密碼的方式失敗還可以嘗試通過如下方式設置
mysql -u root
mysql> use mysql;
mysql> UPDATE user SET Password = PASSWORD(‘newpass‘) WHERE user = ‘root‘;
mysql> FLUSH PRIVILEGES;
5、為遠程客戶端連接授權
mysql -u root –p //會提示輸入密碼,輸入上面設置的root新密碼
GRANT ALL PRIVILEGES ON *.* TO [email protected]%‘ IDENTIFIED BY ‘newpass‘ WITH GRANT OPTION //*.*表示不對連接的ip做限制
6、對my.cnf中的配置進行設置(文件一般在/etc/my.cnf)
[mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock security risks symbolic-links=0 max_connections = 1000 default-character-set=utf8 max_allowed_packet = 16M skip-name-resolve event_scheduler = on
7、重啟mysql服務
/etc/init.d/mysqld restart
