我使用此教程使用此教程:在Ubuntu 16.04
in intern next nextcloud 9中,使用Ubuntu 16.04,nginx,php7.0,Mariadb,NextCloud和外部Dyndn设置了我的第一台Ubuntu服务器。一切正常,但是由于第二天我重新启动了服务器,因此NextCloud向我展示了一个空白页。在单击NGINX,MariadB和NextCloud的所有日志之后,我发现MySQL服务不会启动。因此,运行service mysql start
,一切都可以正常工作(从服务器和其他工作站调用NextCloud)。我只是想知道终端没有"关闭"线路。就像它仍在处理命令一样。大约5分钟后,将"关闭"行并出现以下消息:
" Mariadb.Service的工作失败了,因为超出了超时。请参阅 有关详细信息
然后,客户再次在NextCloud中获取空白页。当我运行命令并立即关闭终端时,客户也将获得访问权限,但在5分钟后仍然丢失。
我尝试备份NextCloud,SQL并运行apt-get purge --auto-remove mariadb-server
。然后,通过导入备份SQL,而不是创建新的,然后再运行MariadB安装步入教程。没有改变一切。
下一个尝试是update-rc.d mysql defaults
和update-rc.d mysql enable
。但是,在再次重新启动空白页之后。仅通过启动服务手册才能访问5分钟。
我还尝试了Bum -bootupmanager,但该服务似乎已启用。我看到您也可以手动启动服务。因此,用mysql和惊喜尝试了一下:NextCloud可用5分钟,而Bum挂断了。
我也发现了mariadb.com/kb/en/mariadb/starting-and-stopping-mariadb-autopical//-2.1,但没有尝试过,因为似乎还有其他问题。

不幸的是,Google无法帮助我。我试图尽可能多地解释我可以帮助您帮助我。非常感谢!
如果您被此错误咬伤,则该解决方案是在错误报告中作为建议(所有这些都必须是作为root完成,因此用sudo -i
作为Zeroth命令或使用sudo
前缀):
-
echo "/usr/sbin/mysqld { }" > /etc/apparmor.d/usr.sbin.mysqld
(sudo的第二部分是... | sudo tee /etc/apparmor.d/usr.sbin.mysqld
,谢谢@dvlcube) -
apparmor_parser -v -R /etc/apparmor.d/usr.sbin.mysqld
-
systemctl restart mariadb
背景
如果您以前安装了MySQL,它激活了与Mariadb不相容的Apparmor配置文件。apt-get remove --purge
仅删除配置文件,但不会停用/卸载它。只有手动卸载它才能让Mariadb不受Apparmor的限制。
这个最后一个选项对我有用(来自Quazgar)。我的Ubuntu 18.10安装了Mariadb 10.3.13:
$ echo "/usr/sbin/mysqld { }" > /etc/apparmor.d/usr.sbin.mysqld
$ apparmor_parser -v -R /etc/apparmor.d/usr.sbin.mysqld
$ systemctl restart mariadb
我不得不使用" sudo su"才能工作。
将mysqld移至"抱怨"组是不够的(Mariadb 10.1.21在Ubuntu 16.04上运行)。我必须完全禁用mysqld:
sudo ln -s /etc/apparmor.d/usr.sbin.mysqld /etc/apparmor.d/disable/
sudo service apparmor reload
sudo service mysql restart
现在一切正常。
漫长的问题一无所有...从来没有听说过Apparmor,但这是重新确定的。这里的答案修复了。不在乎Apparmor的错误不存在。
sudo aa-status
向您展示Apparmor在做什么;实际上有一个 强制政策,而不是刚刚抱怨的事情。
sudo apt-get install apparmor-utils
添加了一些命令 Apparmor配置文件易于处理,例如...
sudo aa-complain /usr/sbin/mysqld
将配置文件从"执行"转换为 抱怨。(aa-enforce将其倒退。)完成后,
sudo service apparmor reload
重新启动Apparmor,然后 瞧...sudo /etc/init.d/mysql start
有效,服务器静置。
fyi:
在我的情况下,Vincent或LW BI的解决方案既不工作,我需要进一步的动作。
通过在/etc/apparmor.d/disable/
中放置链接禁用配置文件根本不起作用,我不知道为什么。
另一方面,将mysql设置为投诉模式也不立即工作。
:~$ sudo aa-complain /usr/sbin/mysqld
将/usr/sbin/mysqld
设置为投诉模式。
ERROR: /etc/apparmor.d/usr.sbin.mysqld contains no profile
我需要添加行:
/usr/sbin/mysqld {
}
到/etc/apparmor.d/usr.sbin.mysqld
,然后我可以将其设置为成功投诉模式。
请注意,由于10.1.10,Mariadb使用Systemd来启动服务。如果您尝试过MySQLD_STARTUP_TIMEOUT,但它尚未使用,则可能正在使用此版本或以后的版本。/etc/init.d/mysql脚本不再使用,因此mysqld_startup_timeout无效。
您需要查找您的MariaDB.Service文件。在我们的情况下,它不包含超时,因此使用了MariadB默认值。只需添加:
timeoutstartsec = 0
在[服务]部分中,它永远不会超时。
创建包含此的配置文件是一个好主意,以免后来重新安装。
在Ubuntu 18.04上,您将在
中罚款此文件/lib/systemd/system/mariadb.service
将您自己的文件放入
中/etc/systemd/system/mariadb.service.d
记住在将超时添加到某个地方之后运行SystemCtl守护程序 - 重加载(也许可以检查/var/log/syslog以查看重新加载是否成功),否则您的时间将被忽略。
运行以下命令:
sudo dpkg --configure -a
sudo service mysql start
我也面临同一问题。您需要在MariaDB服务的SystemD配置中设置适当的超时。下面对我解决了同样的问题。对于前。当系统需要SST时
如果您使用的是SystemD 228或以上,则可以执行以下操作以设置无限超时。
sudo tee /etc/systemd/system/mariadb.service.d/timeoutsec.conf <<EOF
[Service]
TimeoutStartSec=0
TimeoutStopSec=0
EOF
sudo systemctl daemon-reload
有关其他选项,请参阅https://mariadb.com/kb/en/systemd/pp>
i我拥有相同的ISSU。这是一个丢失的证书文件,链接到/etc/mysql/mariadb.conf.d/50-server.cnf这是缺少的:/etc/mysql/ssl/server-key.pem
必须将其从CTRL C的另一个节点复制到Nano中。在使用SCP复制时获得了权限错误。
校正对我不起作用。
$ sudo aa-complain/usr/sbin/mysqld设置/usr/sbin/mysqld to 投诉模式。
错误:/etc/apparmor.d/usr.sbin.mysqld不包含个人资料,所以我 禁用配置文件(使用AA-DISABLE似乎等同于 Plutocrat的解决方案)
$ sudo aa-disable/usr/sbin/mysqld禁用/usr/sbin/mysqld。我 残疾Mysqld-Akonadi和MySQLD-Digikam。
Apparmor重新加载还不够,所以我不得不重新启动和Mariadb 开始得很好。
来源:https://askubuntu.com/a/964928/106100
我的解决方案是运行以下内容:
sudo killall mysqld
如果您仍在遇到此问题,请运行命令ps -aux | grep 'mysql'
。如果有什么出现的话,也要杀死它。
最终运行:
sudo systemctl restart mysql.service
