我在 AWS EC2 微型实例上安装了 MySQL 服务器。服务器可以正常启动/停止，sudo 服务 mysql 启动/停止，但是由于我对配置文件做了一些小改动（更改了端口值并注释掉了绑定地址行），它就停止工作了。
现在当我这样做sudo 服务 mysql 启动它说启动：作业启动失败。
我也尝试过执行 sudo mysqld --port xx 但仍然不起作用。
我对这个领域还很陌生，所以任何帮助都将非常有帮助。
编辑：这是配置
[client]
port = xx
socket = /var/run/mysqld/mysqld.sock
[mysqld_safe]
socket = /var/run/mysqld/mysqld.sock
nice = 0
[mysqld]
#
# * Basic Settings
#
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = xx
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address = (local ip address)
#
# * Fine Tuning
#
key_buffer = 16M
max_allowed_packet = 16M
thread_stack = 192K
thread_cache_size = 8
# This replaces the startup script and checks MyISAM tables if needed
# the first time they are touched
myisam-recover = BACKUP
#max_connections = 100
#table_cache = 64
#thread_concurrency = 10
#
# * Query Cache Configuration
#
query_cache_limit = 1M
query_cache_size = 16M
#
# * Logging and Replication
#
# Both location gets rotated by the cronjob.
# Be aware that this log type is a performance killer.
# As of 5.1 you can enable the log at runtime!
#general_log_file = /var/log/mysql/mysql.log
#general_log = 1
#
# Error log - should be very few entries.
#
log_error = /var/log/mysql/error.log
由于这只是默认设置，因此我不会发布更多配置

关于绑定地址：我不确定应该将绑定地址设置为什么。将其设置为 0.0.0.0 对 mongodb 有效，但从我在这里看到的情况来看，我不应该这样做？这仅用于性能测试，因此我不需要担心安全性。
更多编辑：当我更改配置文件上的端口值时，它再次起作用，但遗憾的是我被迫使用特定的端口。
最终编辑：
我花了大约 7 个小时尝试修复此问题，但最终还是失败了。我要求老板开放端口 3306，然后改用该端口。
