服务器退出而不更新PID文件-Ubuntu12.04服务器

Question

我按照这个链接来升级mysql，https://rtcamp.com/tutorials/mysql/mysql-5-6-ubuntu-12-04/。

本文ubuntu是x64，但我的ubuntu是x32，所以我将下载链接更改为http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.16-debian6.0-i686.deb。

当我完成安装时，输入以下命令启动mysql：$ service mysql.server start

它提醒我：

Starting MySQL
. * The server quit without updating PID file (/var/run/mysqld/mysqld.pid).

当我尝试键入service mysql-server restart时，它会提醒我一些不同之处：

 * MySQL server PID file could not be found!
Starting MySQL
. * The server quit without updating PID file (/var/run/mysqld/mysqld.pid).

也许有什么能帮到你的：

• my.cnf位于/etc/mysql/my.cnf
• 当再次键入ps aux | grep mysql时，ps aux | grep mysql将显示不同的PID。

my.cnf文件有以下行

# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...
# Remember to edit /etc/mysql/debian.cnf when changing the socket location.
[client]
port        = 3306
socket      = /var/run/mysqld/mysqld.sock

# Here is entries for some specific programs
# The following values assume you have at least 32M ram

# This was formally known as [safe_mysqld]. Both versions are currently parsed.
[mysqld_safe]
socket      = /var/run/mysqld/mysqld.sock
nice        = 0

Answer 1

在文件夹"/var/run/mysqld/“中创建一个名为"mysqld.pid”的新文件，然后编辑该文件，例如将第1行设置为: 1329，然后再次启动服务器

Answer 2

通过命令rm -f 'filename.pid‘删除所有现有的pid文件

然后启动服务器..。

谢谢
