今天启动MySQL 遇见了这个问题,网上搜索,结果各种改文件,删除文件纯属坑爹;在上边的网站上发现了问题的解决方案~老外总结的真不错!拿过来自己学习一下

bubuko.com,布布扣This step-by-step guide is mainly for FreeBSD, however the idea is the same for Linux. Every once a while, when I update my FreeBSD box, the system likes to shutdown my MySQL server. Therefore, I need to start it again after the update is done. Unfortunately, the upgrade process is not smooth every time. Sometimes it will throw me some error.

1,启动MySQL
/usr/local/etc/rc.d/mysql.server start 
2,发现了下述错误
  
  Starting MySQL..... ERROR! The server quit without updating PID file.

3,错误信息很明确的定位你出现的问题
 Starting MySQL..... ERROR! The server quit without updating PID file (/var/db/mysql/www.icesquare.com.pid).
三种解决方案如下:

Solution 1: Reboot The Computer 重启你的电脑

 Although it sounds simple, but it really works. During the system upgrade, the OS may disable some of your daemons. Instead of troubleshooting each one by one, the easiest way is to start everything over. For example, I experienced this problem today after upgrading the Apache and Ruby (Yes, MySQL is not part of the update), and I got this error message afterward. After rebooting the computer, the error message is gone.
 这个是由于更新引起的,你重启电脑即可解决。

Solution 2: Remove Your MySQL Config File 删除你的配置文件

If you have modified your MySQL configuration file, MySQL may not like it few versions after (MySQL is not backward compatibility friendly). It can be the problem of using an unsupported variable, or something similar. The easiest way is to remove your configuration file, and try to start the MySQL server again:

Backup your MySQL configuration first.

mv /etc/my.cnf /etc/my.cnf.backup

And restart the MySQL server again:

/usr/local/share/mysql/mysql.server start

Hopefully you will see the following message:

Starting MySQL. SUCCESS!

Solution 3: Upgrade Your Database File 更新你的数据库文件

Sometimes, the newer MySQL doesn’t like the database created in earlier version. I discovered this when I upgrade to MySQL 5.5.7:

Starting MySQL..... ERROR! The server quit without updating PID file (/var/db/mysql/www.icesquare.com.pid).


Since MySQL tells me which PID file causes the problem, I open the file and take a look what’s going on:

sudo tail /var/db/mysql/www.icesquare.com.err

And I saw something interesting: tables: Table ‘mysql.proxies_priv’ doesn’t exist:
101112 10:49:16  InnoDB: Initializing buffer pool, size = 128.0M
101112 10:49:16  InnoDB: Completed initialization of buffer pool
101112 10:49:16  InnoDB: highest supported file format is Barracuda.
101112 10:49:17  InnoDB: 1.1.3 started; log sequence number 1589404
101112 10:49:17 [ERROR] Fatal error: Can‘t open and lock privilege tables: Table ‘mysql.proxies_priv‘ doesn‘t exist
101112 10:49:17 mysqld_safe mysqld from pid file /var/db/mysql/www.icesquare.com.pid ended

The reason is very simple. MySQL could not open a table created in the earlier version (< 5.7.7) because it is not compatible with the current version. So, we can try to start the MySQL in safe mode through rc.d. First, you can edit the /etc/rc.conf and put the following into the file:

mysql_enable="YES"
mysql_args="--skip-grant-tables --skip-networking"

Restart MySQL through rc.d:
If you did it right, you should see something like the following:
Starting MySQL.. SUCCESS!

Now, MySQL is already running the safe-mode. We want to perform a MySQL upgrade on all tables:

sudo mysql_upgrade

You should see something like this:

Looking for ‘mysql‘ as: mysql
Looking for ‘mysqlcheck‘ as: mysqlcheck
Running ‘mysqlcheck‘ with connection arguments: ‘--port=3306‘ ‘--socket=/tmp/mysql.sock‘
Running ‘mysqlcheck‘ with connection arguments: ‘--port=3306‘ ‘--socket=/tmp/mysql.sock‘
mysql.columns_priv                                 OK
mysql.db                                           OK
mysql.event                                        OK
mysql.func                                         OK
mysql.general_log                                  OK
mysql.help_category                                OK
mysql.help_keyword                                 OK
mysql.help_relation                                OK
mysql.help_topic                                   OK
mysql.host                                         OK
mysql.ndb_binlog_index                             OK
mysql.plugin                                       OK
mysql.proc                                         OK
mysql.procs_priv                                   OK
mysql.servers                                      OK
mysql.slow_log                                     OK
mysql.tables_priv                                  OK
mysql.time_zone                                    OK
mysql.time_zone_leap_second                        OK
mysql.time_zone_name                               OK
mysql.time_zone_transition                         OK
mysql.time_zone_transition_type                    OK
mysql.user                                         OK
Running ‘mysql_fix_privilege_tables‘...
OK

Now, we want to switch the MySQL back to normal mode by commenting the extra options in /etc/rc.conf:

mysql_enable="YES"
#mysql_args="--skip-grant-tables --skip-networking"

And restart MySQL through /etc/rc.d:

/usr/local/etc/rc.d/mysql-server restart

Now the MySQL is up and running again!

Happy MySQLing.
