Question

我无法启动mysql和mysqld。

sudo service mysql start命令的输出为mysql : Unrecognized service

同样的方式sudo service mysqld start的输出是什么

当我尝试sudo service mysqld status时，它会显示stopped

注意：我正在使用rhel 6.5 MySQL版本是mysqld Ver 5.6.21-ndb-7.3.7-cluster-gpl for linux-glibc2.5 on x86_64（MySQL Cluster Community Server（GPL））

我经历了/var/log/mysql.log发现此错误：

2015-10-20 08:00:54 23694 [Note] InnoDB: 128 rollback segment(s) are active.

我在网上看了一下，并试图修复说是权限的问题，所以我创建了修复/var/run/mysqld mysql.pid chown和mysql:mysql目录的错误到/var/lib/mysql

但问题仍然存在。任何人都可以帮我解决这个问题！

Answer 1

执行命令

sudo mv /usr/local/mysql /usr/local/old.mysql
sudo yum install mysql-server mysql
sudo mysql_install_db
sudo mysql_secure_installation
sudo chkconfig mysqld on
sudo service mysqld start

MySQL启动错误（无法启动服务器：无法创建PID文件：没有这样的fie或目录）
