MySQL: Starting MySQL….. ERROR! The server quit without updating PID file解决办法

1 问题

[root@localhost mysql]# /etc/rc.d/init.d/mysql status
MySQL is not running, but lock file (/var/lock/subsys/mysql[FAILED]
[root@localhost mysql]# /etc/rc.d/init.d/mysql start
Starting MySQL...The server quit without updating PID file (/usr/local/mysql/data/localhost.localdomain.pid).                              [FAILED]

 

2 原因

没有初始化权限表

 

3 解决办法

#cd /usr/local/mysql(进入mysql安装目录)
#chown -R mysql.mysql .
#su - mysql
$cd server
$scripts/mysql_install_db

 

4 本人解决过程

[root@localhost ~]# cd /usr/local/mysql

[root@localhost mysql]# chown -R mysql.mysql .
[root@localhost mysql]# su - mysql
[mysql@localhost ~]$ cd /usr/local/mysql
[mysql@localhost mysql]$ scripts/mysql_install_db
Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h localhost.localdomain password 'new-password'

Alternatively you can run:
./bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd . ; ./bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd ./mysql-test ; perl mysql-test-run.pl

Please report any problems with the ./bin/mysqlbug script!

[mysql@localhost mysql]$ /usr/local/mysql/bin/mysqld_safe --user=mysql &

MySQL: <wbr>Starting <wbr>MySQL….. <wbr>ERROR! <wbr>The <wbr>server <wbr>quit <wbr>without <wbr>updating <wbr>PID <wbr>file解决办法



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.

/usr/local/etc/rc.d/mysql.server start

Oh well, I got the following error messages:

Starting MySQL..... ERROR! The server quit without updating PID file.

Sometimes, the message will tell you the exact location of which PID file:

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

There are several solutions to troubleshoot these problems. I will go over each one by one.

Solution 1: Reboot The Computer

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.

Solution 2: Remove Your MySQL Config File

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

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:

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

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.

### 解决MySQL服务器启动时出现错误,未更新PID文件 当遇到 `ERROR! MySQL server PID file could not be found` 或者 `The server quit without updating PID file` 错误时,这通常意味着MySQL服务未能正常初始化并创建进程ID (PID) 文件。以下是几种可能的原因以及相应的解决方案。 #### 检查配置文件路径设置 确保my.cnf或my.ini中的datadir参数指向的是实际存在的目录,并且该位置有足够的写权限给运行mysqld的服务账户[^1]。 #### 清理残留的PID文件 有时旧有的、不再有效的`.pid`文件会阻止新的实例启动。应当手动移除位于指定的数据存储区域内的此类文件后再尝试重启服务[^2]。 #### 初始化数据目录 如果怀疑是由于数据损坏引起的问题,则可以在备份现有数据之后,在MySQL安装下的bin文件夹内通过命令提示符窗口输入如下指令来重新初始化数据目录: ```bash mysqld --initialize --console ``` 此操作将会生成一个新的root用户的临时密码,请妥善保管以便后续登录验证使用[^3]。 #### 数据库文件恢复或替换 对于因意外关闭或其他原因造成数据库内部结构受损的情况,可以考虑利用之前备份好的完好无损的一套表空间文件(如ibdata1, ib_logfile0等),将其复制到当前环境相应的位置上以实现快速修复。 #### 日志分析排查其他潜在问题 查看error log获取更多详细的报错信息有助于进一步诊断具体是什么阻碍了MySQL的成功启动。日志文件一般存放在与数据相同的文件夹里或者是按照自定义配置放置于其它地方。 ---
