無法在Google計算引擎上啟用bin-log

Question

我正在嘗試在Google的LAMP堆棧上設置bin-log。 除了log-bin配置以外，其他一切都正常。 每當我將log-bin = /var/log/mysql/mysql-bin到/etc/mysql/mysql.conf.d/mysqld.cnf文件並重新啟動mysql時，它將引發錯誤

    # 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的內容

[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可能具有必需的權限，因為mysql可以在/var/log/mysql/error.log上記錄錯誤。 但是無論如何我也嘗試過這些

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

我已經嘗試了這些帖子中提供的解決方案，但對我沒有任何幫助

詳細的錯誤日志error-log

這可能很容易成為您在其上運行的服務器（AppArmor或SELinux）上的安全設置的問題。 請注意，二進制日志實際上不是與通常放置在/ var / log中的常規文本文件相同的意義上的“日志”，並且您可能始終不想將該文件放置在/ var / log中。 可能是在您運行的設置中，AppArmor或SELinux規則阻止mysql將任意文件寫入/ var / log（這些規則超出了常規文件權限的限制，沒有chmod / chown可以避免它們）。 您可能要考慮選擇另一個目錄來將bin-log保存到其中。

也許數據庫根目錄是一個更好的選擇（ /var/lib/mysql ，或者配置為用來存儲數據庫文件的任何mysql）。
