我想在谷歌的灯堆上设置bin log。一切正常，除了日志箱配置。每当我加上 log-bin = /var/log/mysql/mysql-bin 至 /etc/mysql/mysql.conf.d/mysqld.cnf 文件，然后重新启动mysql。它抛出一个错误
# 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=0mysql:root might 具有必需的权限，因为mysql可以登录错误 /var/log/mysql/error.log . 但不管怎样我也试过了
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，但都不适合我

这很容易成为您运行的服务器（apparmor或selinux）上的安全设置的问题。请注意，二进制日志实际上并不是一个与通常放在/var/log中的常规文本文件相同意义上的“日志”，无论如何，您可能不想将该文件放在/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作用，chmod/chown无法避免它们）。您可能需要考虑选择另一个目录来保存bin日志。
也许数据库根目录是一个更好的选择(
/var/lib/mysql，或任何mysql配置为用作存储其数据库文件的位置）。
