AWS實例上的Mysql啓動失敗

我無法在aws.ec2.instance上啓動mysqld，colude幫我嗎？

我不知道爲什麼？

$ sudo yum install -y mysql mysql-server 
$ sudo mysql_install_db 
$ sudo service mysqld start 
MySQL Daemon failed to start. 
Starting mysqld:           [FAILED]

打擊是一些文件，以顯示我的ENV ..

的/etc/my.cnf

[mysqld] 
# Settings user and group are ignored when systemd is used. 
# If you need to run mysqld under different user or group, 
# customize your systemd unit file for mysqld according to the 
# instructions in http://fedoraproject.org/wiki/Systemd 
datadir=/var/lib/mysql 
socket=/var/lib/mysql/mysql.sock 
# Disabling symbolic-links is recommended to prevent assorted security risks 
symbolic-links=0 

[mysqld_safe] 
log-error=/var/log/mysqld.log 
pid-file=/var/run/mysqld/mysqld.pid

只屬於ServerFault。您的MySQL數據文件夾已被刪除，MySQL表不再存在。需要從頭開始清理和重新配置。 –

嘗試查找文件host.frm並檢查組和它屬於的用戶。「錯誤號：13」是指：

~$ perror 13 
OS error code 13: Permission denied

所以它可能是。如果你沒有這樣的文件（也就是在mysql中的表），您必須用再生他們：

~$ mysql_install_db

乾杯，

我在多個AWS服務器上多次看到過這個問題，在我的案例中主要的根本原因是缺乏空間。

所以，只是釋放服務器上的一些空間，並重新啓動你的mysqld，它應該開始工作正常。
