mysql 无法自动启动

我希望 mysql 在启动时启动，但是它没有启动，因为当我不想让它自动启动时，我之前删除了 rc.something（不记得它是什么）。

现在为了运行它我需要运行：

sudo service mysql start

每次我打开电脑时，这很烦人。

如何解决这个问题？

您正在寻找的命令可能是

sudo update-rc.d mysql defaults

/etc/init.d/mysql

默认脚本：

#!/bin/sh -e
# upstart-job
#
# Symlink target for initscripts that have been converted to Upstart.

set -e

INITSCRIPT="$(basename "$0")"
JOB="${INITSCRIPT%.sh}"

if [ "$JOB" = "upstart-job" ]; then
    if [ -z "$1" ]; then
        echo "Usage: upstart-job JOB COMMAND" 1>&2
        exit 1
    fi

    JOB="$1"
    INITSCRIPT="$1"
    shift
else
    if [ -z "$1" ]; then
        echo "Usage: $0 COMMAND" 1>&2
        exit 1
    fi
fi

COMMAND="$1"
shift


if [ -z "$DPKG_MAINTSCRIPT_PACKAGE" ]; then
        ECHO=echo
else
        ECHO=:

$ECHO "Rather than invoking init scripts through /etc/init.d, use the service(8)"
$ECHO "utility, e.g. service $INITSCRIPT $COMMAND"

# Only check if jobs are disabled if the currently _running_ version of
# Upstart (which may be older than the latest _installed_ version)
# supports such a query.

# This check is necessary to handle the scenario when upgrading from a
# release without the 'show-config' command (introduced in
# Upstart for Ubuntu version 0.9.7) since without this check, all
# installed packages with associated Upstart jobs would be considered
# disabled.
#
# Once Upstart can maintain state on re-exec, this change can be
# dropped (since the currently running version of Upstart will always
