Question

我试图在Google的LAMP堆栈上设置bin-log。除了log-bin配置外，一切正常。每当我将log-bin = /var/log/mysql/mysql-bin添加到/etc/mysql/mysql.conf.d/mysqld.cnf文件并重新启动mysql时，它都会抛出错误

    # sudo /etc/init.d/mysql restart
[....] Restarting mysql (via systemctl): mysql.serviceJob for mysql.service failed because the control process exited with error code.
See "systemctl status mysql.service" and "journalctl -xe" for details.
 failed!

/etc/mysql/mysql.conf.d/mysqld.cnf的内容

[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
log-error       = /var/log/mysql/error.log
bind-address    = localhost
log-bin         = /var/log/mysql/mysql-bin
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

mysql：root可能具有必需的权限，因为mysql可以在/var/log/mysql/error.log上记录错误。但无论如何我也试过这些

chown -R mysql:mysql /var/log/mysql/
chmod 770 /var/log/mysql/
# and
chown -R mysql:root /var/log/mysql/

我已经尝试过这些帖子中给出的解决方案，但没有任何方法可以帮助我

这可能很容易成为您在其上运行的服务器（AppArmor或SELinux）上的安全设置的问题。请注意，二进制日志实际上不是与通常放置在/ var / log中的常规文本文件相同的意义上的“日志”，并且您可能始终不想将该文件放置在/ var / log中。可能是在您运行的设置中，AppArmor或SELinux规则阻止mysql将任意文件写入/ var / log（这些规则超出了常规文件权限的限制，没有chmod / chown可以避免它们）。您可能要考虑选择另一个目录来将bin-log保存到该目录中。

也许数据库根目录是一个更好的选择（/var/lib/mysql，或者任何配置为用作存储数据库文件的mysql）。
