解决1:
出现以上安装错误列表的原因是:系统已经安装了其他版本的mysql-libs包和mysql数据库文件导致不兼容。
[plain] view plaincopy
- [root@localhost install-files]# yum remove mysql-libs
执行之后,还要详细检查卸载MySQL安装的所有文件,否则在后续安装发生各种错误:CentOS下MySQL的彻底卸载
问题2:
[root@Tony_ts_tian developer]# rpm -ivh MySQL-server-5.5.46-1.el6.x86_64.rpm
warning: MySQL-server-5.5.46-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

解决2:
从 rpm版本 4.1 开始,在安装或升级软件包时会检查软件包的签名。如果签名校验失败,你就会看到类似以上的错误消息:
注:新的、只针对文件头的签名:错误消息:error: Header V3 DSA signature: BAD, key ID 0352860f
注:没有安装合适的钥匙来校验签名,消息中就会包含 NOKEY:错误消息:warning: V3 DSA signature: NOKEY, key ID 0352860f
由于yum安装了旧版本的GPG keys造成的,解决办法就是(设置后无效):
[plain] view plaincopy
- rpm --import /etc/pki/rpm-gpg/RPM*
此签名是检验安装包的有效性和安装性的。我直接跳过(安装时不校验,加--nosignature参数)检验安装:
[plain] view plaincopy
- [root@localhost install-files]# rpm -ivh MySQL-server-5.6.27-1.el6.x86_64.rpm --nosignature
问题3:
mysqld: unrecognized service
[plain] view plaincopy
- [root@Tony_ts_tian init.d]# service mysqld start
- mysqld: unrecognized service
解决3:
启动脚本文件mysql的目录
[plain] view plaincopy
- [root@localhost install-files]# cd /etc/rc.d/init.d/
- [root@localhost init.d]# ls
- functions mysql netconsole network README
并没有mysqld:
CentOS7下安装MySQL数据库常见问题 1. ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (2) 1. 检查M
[plain] view plaincopy
- [root@Tony_ts_tian init.d]# service mysql start
启动成功:
也可以:
[plain] view plaincopy
- [root@Tony_ts_tian init.d]# mv mysql mysqld
- [root@Tony_ts_tian init.d]# service mysqld start

查看路径:mysql-bin.index多余文件,auto.cnf和performance_schema等不存在(文件不全)。(以上为成功后的mysql数据库目录)
解决5:
因为以前存在的MySQL卸载不干净导致。
删除和卸载(以下是的解决),然后重新安装:CentOS下MySQL的彻底卸载
