1：检查是否安装MySQL：
方法1：
[root@localhost ~]# yum list installed mysql* Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.btte.net * extras: mirrors.btte.net * updates: mirrors.opencas.cn Error: No matching Packages to list
方法2：
[root@localhost ~]# rpm -qa | grep -i mysql [root@localhost ~]#
2：查看yum服务器可下载mysql的版本信息:
[root@localhost ~]# yum list | grep mysql
3：看着yum服务器有没有合适的安装包：
[root@localhost ~]# yum list mysql*
安装前：注：之前安装过MySQL或者有残留，请查看:CentOS下MySQL的彻底卸载
注：遇到问题请查看：CentOS7安装MySQL冲突和问题解决小结
4：yum安装MySQL：
#安装MySQL客户端 [root@localhost ~]# yum install mysql #安装MySQL服务端 [root@localhost ~]# yum install mysql-server #安装MySQL的库和头文件 [root@localhost ~]# yum install mysql-devel
5：rpm安装MySQL：
1:下载mysql安装包（全）:
http://mysql.mirrors.pair.com/Downloads/
http://ftp.kaist.ac.kr/mysql/Downloads/ （推荐）
2:已准备安装rpm文件:
[root@localhost install-files]# pwd /home/install-files [root@localhost install-files]# ll 总用量 241452 -rw-r--r--. 1 root root 9106353 10月 8 23:15 apache-tomcat-8.0.24.tar.gz -rw-r--r--. 1 root root 160084320 10月 8 23:17 jdk-8u60-linux-x64.rpm -rw-r--r--. 1 root root 18596528 10月 11 13:24 MySQL-client-5.6.27-1.el6.x86_64.rpm -rw-r--r--. 1 root root 3392620 10月 11 13:24 MySQL-devel-5.6.27-1.el6.x86_64.rpm -rw-r--r--. 1 root root 55950588 10月 11 13:25 MySQL-server-5.6.27-1.el6.x86_64.rpm -rw-r--r--. 1 root root 98362 10月 8 23:45 sshpass-1.05.tar.gz3
3：安装MySQL服务端:
[root@localhost install-files]# rpm -ivh MySQL-server-5.6.27-1.el6.x86_64.rpm --nosignature Preparing... ################################# [100%] Updating / installing... 1:MySQL-server-5.6.27-1.el6 ################################# [100%] …………………… 省略log，文章后备注附件。
检查: [root@localhost bin]# mysql --version mysql Ver 14.14 Distrib 5.6.27, for Linux (x86_64) using EditLine wrapper
安装服务器遇到错误和警告：CentOS7安装MySQL冲突和问题解决小结
问题1：file /usr/share/mysql/charsets/README from install of MySQL-server-5.6.27-1.el6.x86_64 conflicts with file from package mariadb-libs-1:5.5.41-2.el7_0.x86_64………
问题2：warning: MySQL-server-5.5.46-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
问题3：mysqld: unrecognized service
问题4：FATAL ERROR: please install the following Perl modules before executing /usr/bin/mysql_install_db: Data::Dumper
问题5：Starting MySQL... ERROR! The server quit without updating PID file (/var/lib/mysql/localhost.localdomain.pid).
4：安装MySQL的库和头文件:
[root@localhost install-files]# rpm -ivh MySQL-devel-5.6.27-1.el6.x86_64.rpm --nosignature Preparing... ################################# [100%] Updating / installing... 1:MySQL-devel-5.6.27-1.el6 ################################# [100%]
5：安装MySQL客户端：
[root@localhost install-files]# rpm -ivh MySQL-client-5.6.27-1.el6.x86_64.rpm --nosignature Preparing... ################################# [100%] Updating / installing... 1:MySQL-client-5.6.27-1.el6 ################################# [100%]
检验: [root@localhost bin]# find /usr/bin -name mysqladmin /usr/bin/mysqladmin [root@localhost bin]# find /usr/bin -name mysqldump /usr/bin/mysqldump
注:以下操作rpm和yum安装完成之后操作为一致。
以上安装为默认路径安装,如果要设置路径rpm参数(--relocate,--badreloc):
mysql安装目录：
1.数据库目录 /var/lib/mysql/ 2.配置文件 /usr/share/mysql(mysql.server命令及配置文件) 3.启动脚本 /etc/rc.d/init.d/(启动脚本文件mysql的目录) 4.相关命令 /usr/bin(mysqladmin mysqldump等命令)
注:1~3安装server安装后存在,4mysqladmin mysqldump在client安装后存在
6:启动和关闭mysql:
[root@localhost init.d]# pwd /etc/rc.d/init.d [root@localhost init.d]# ls functions jexec mysql netconsole network README
[root@localhost install-files]# service mysql start Starting MySQL.. SUCCESS! [root@localhost install-files]# service mysql stop Shutting down MySQL.. SUCCESS!
这个版本安装的mysql的启动脚本为mysql而非mysqld。
问题:
问题3：mysqld: unrecognized service
问题5：Starting MySQL... ERROR! The server quit without updating PID file (/var/lib/mysql/localhost.localdomain.pid).

See the manual for the semantics of the 'password expired' flag. Also, the account for the anonymous user has been removed. In addition, you can run: /usr/bin/mysql_secure_installation which will also give you the option of removing the test database. This is strongly recommended for production servers. See the manual for more instructions.
