希望你能帮忙。我的Mariadb/MySQL数据库一直失败，日志中有此消息：

===============
Service Error
(XID fseu38) The “mysql” service failed to start.
Startup Log
Starting MariaDB.230914 21:53:41 mysqld_safe Logging to '/var/lib/mysql/gla.glassheadz.com.err'.
230914 21:53:41 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
.........../etc/init.d/mysql: line 264: kill: (31815) - No such process
 ERROR!
=================

第64行是这段代码的一部分：

wait_for_ready () {
  i=0
  while test $i -ne $service_startup_timeout ; do
    if $bindir/mysqladmin ping >/dev/null 2>&1; then
      log_success_msg
      return 0
    elif kill -0 $! ; then
      :  # mysqld_safe is still running
    else
      # mysqld_safe is no longer running, abort the wait loop
      break
    fi
    echo $echo_n ".$echo_c"
    i=`expr $i + 1`
    sleep 1
  done

如果你尝试加载一个网站，如goodinthehead.com，你会看到Error establishing database connection问题解决后，重新启动，但错误再次发生后，一两天，所以它可能会或可能不会工作，当你尝试它。
我还没有熟练到可以试着破译错误...
