Question

Magento显示＆＃34;处理您的请求时出现错误＆＃34;

当试图命令＆＃34; sudo service mysqld restart＆＃34;但未能开始

然后看日志显示我＆＃34; SQLSTATE [HY000] [2002]没有这样的文件或目录＆＃34;

我在Google，stackoverflow，magento stackoverflow网站上搜索很少，最后得到的东西可能是

命令后＃34; mysqld -u root -p status＆＃34;

显示＆＃39; mysqladmin：在＆＃39; localhost＆＃39;连接到服务器失败错误：＆＃39;无法通过socket＆＃39; /var/lib/mysql/mysql.sock'连接到本地MySQL服务器; （2）＆＃39; 检查mysqld是否正在运行以及socket：＆＃39; /var/lib/mysql/mysql.sock'存在！

我发现我在/ var / lib / mysql /中没有mysql.sock现在应该怎么做。我不是新手专家。不幸的是，我给了ec2实例中所有目录的777权限，在这个问题的一段时间后，我看到了我的网站＆＃34;处理您的请求时出错。出于ec2安全原因，我无法使用ftp或ssh访问实例。所以我不得不创建新实例将此EBS提供给新实例，在更改权限后我可以访问我的实例

请查看我的my.cnf文件。我看到有些东西可以提供帮助

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mysqld according to the
# instructions in http://fedoraproject.org/wiki/Systemd

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

这是mysqld.log

/usr/libexec/mysql55/mysqld: Can't create/write to file '/tmp/ibmCz4dv'     (Errcode: 13)
160212 18:29:37  InnoDB: Error: unable to create temporary file; errno: 13

160212 18:29:37 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended

775到/ tmp和现在的mysqld.log

775到/ tmp和mysqld.log

/usr/libexec/mysql55/mysqld: Can't create/write to file '/tmp/ibLzshr1' (Errcode: 13)

160213 09:08:59 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended

请帮我把它整理出来

Answer 1

mysql用户显然无权根据

在/ tmp中创建文件

/usr/libexec/mysql55/mysqld: Can't create/write to file '/tmp/ibmCz4dv'     (Errcode: 13)

检查/ tmp上的访问权限，应为777。 BTW sys“errno 13”是“Permission denied”

根据这一点，服务器停止并且不创建任何套接字，然后导致连接错误。

Answer 2

我要感谢@ Axel Amthor。最后我给了/ tmp文件777并重新启动了mysqld ..和Boom

网站重新开始行动。对不起，我不能给Upvote，因为我没有声誉15 :(

无法通过socket＆＃39; /var/lib/mysql/mysql.sock&#39连接到本地MySQL服务器; （2）。 / var / lib / mysql /中不存在mysql.sock
