3. 报错解决

#---报错1如下：mysql自动报错

# 解决方式1
mkdir /var/run/mysqld/
cd /var/run/
chown -R mysql.mysql mysqld
mysqld_safe --user=mysql & 
#解决问题
#----------------------------------------------------

#---报错2如下
#----------------------------------------------------
/etc/init.d/mysqld status
ERROR! MySQL is running but PID file could not be found
# 解决方式1
# 重启
kill -9 <>
/etc/init.d/mysqld start 
#解决问题
#----------------------------------------------------

#---报错3如下：初始登陆报错
#----------------------------------------------------
# mysql -uroot -p 
Enter password: 
ERROR 2002 (HY000): Cant connect to local MySQL server through socket '/tmp/mysql.sock' (2)
# 解决方式1
#将配置文件/etc/my.cnf 做如下变更：
socket=/var/lib/mysql/mysql.sock --> socket=/tmp/mysql.sock
#未解决问题

# 解决方式2
在解决方式1的基础上：
停止mysql： kill -9 <>
运行mysqld_safe --skip-grant-tables & 
如果此时不想被远程连接：mysqld_safe --skip-grant-tables --skip-networking &
使用mysql连接server：mysql -uroot -p 
更改密码： update mysql.user set authentication_string=password('123qwe') where user='root' and Host = 'localhost';
*特别提醒注意的一点是，新版的mysql数据库下的user表中已经没有Password字段了

而是将加密后的用户密码存储于authentication_string字段
mysql> flush privileges;
mysql> quit;
修改完毕。重启
killall -TERM mysqld。 
mysqld_safe &
#解决问题
