5、安装时遇见的问题
安装过程中遇见了几个问题，网上搜索答案解决，谢谢大家的分享。在此再次总结一下
问题1：系统已安装包的冲突
解决
[root@mysql soft]# rpm -qa |grep mysql //查找冲突的包 mysql-libs-5.1.71-1.el6.x86_64 [root@mysql soft]# yum -y remove mysql-libs-5.1.71-1.el6.x86_64 //卸载该包 再次安装
问题2：安装完成后MySQL未启动
安装完成后，未启动就开始连接MySQL，报错如下：
[root@mysql soft]# mysql
ERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock‘ (2)
解决：启动MySQL即可
问题3：ERROR 1045 (28000): Access denied for user ‘root‘@‘localhost‘ (using password: NO)
解决：
[root@mysql bin]# /etc/init.d/mysql stop //强行停止MySQL [root@mysql bin]# /usr/bin/mysqld_safe --skip-grant-tables --skip-networking & // [root@mysql bin]# mysql -u root mysql mysql> update user set Password=PASSWORD(‘password‘) where user=‘root‘; Query OK, 4 rows affected (0.00 sec) Rows matched: 4 Changed: 4 Warnings: 0 mysql> FLUSH PRIVILEGES; Query OK, 0 rows affected (0.01 sec) mysql> quit [root@mysql bin]# /etc/init.d/mysql restart //重启两遍 [root@mysql bin]# mysql -u root mysql mysql> SET PASSWORD=PASSWORD(‘passw0rd‘); //需执行此命令才能继续执行其他命令
