MySQL不會在Linux上啓動

我有一個新的MySQL服務器安裝（通過yum安裝）將無法啓動MySQL不會在Linux上啓動

bash-4.1# /sbin/service mysqld start 
MySQL Daemon failed to start. 
Starting mysqld:           [FAILED]

的/etc/my.cnf中已被設置爲默認值：

# For advice on how to change settings please see 
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html 

[mysqld] 
# 
# Remove leading # and set to the amount of RAM for the most important data 
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. 
# innodb_buffer_pool_size = 128M 
# 
# Remove leading # to turn on a very important data integrity option: logging 
# changes to the binary log between backups. 
# log_bin 
# 
# Remove leading # to set options mainly useful for reporting servers. 
# The server defaults are faster for transactions and fast SELECTs. 
# Adjust sizes as needed, experiment to find the optimal values. 
# join_buffer_size = 128M 
# sort_buffer_size = 2M 
# read_rnd_buffer_size = 2M 
datadir=/var/lib/mysql 
socket=/var/lib/mysql/mysql.sock 

# Disabling symbolic-links is recommended to prevent assorted security risks 
symbolic-links=0 

log-error=/var/log/mysqld.log 
pid-file=/var/run/mysqld/mysqld.pid

我收到的錯誤是：

然而，由於mysqld的不運行我不能運行mysql_upgrade。其他網站聲明數據文件的文件權限可能是一個問題，但它們全都屬於mysql（即我認爲正確）。我也嘗試過運行mysqld_safe，但沒有成功。

有人可以建議我做了什麼錯嗎？

都只有不到由'mysql'用戶擁有的'在/ var/lib中/ mysql'的文件嗎？你的文件系統是否已滿？ –

似乎是MySQL的安裝不正確。你可以嘗試卸載並重新安裝或嘗試運行mysql_install_db --user = mysql --basedir =/usr/--ldata =/var/lib/mysql /作爲根 – mark

是的，/ var/lib/mysql下的所有東西都有所有權mysql：mysql，並且文件系統的每個分區上都有空格 –

謝謝馬克。 mysql_install_db不起作用（已棄用，然後建議初始化失敗）。但是，徹底清理並重新安裝可解決問題。作爲參考，我執行的具體步驟爲：

yum remove mysql 
rm -fr /usr/bin/mysql 
rm -fr /var/lib/mysql 
rm -fr /etc/my* 
(reboot) 
yum install mysql-community-{server,client,common,libs}-* 
/sbin/service mysqld start
