centos 6.9安装mysql的详细教程
1、确认mysql是否已安装，有下面的代码可知
[root@cdh1zjl]#yumlistinstalledmysql* Loadedplugins:fastestmirror,refresh-packagekit,security Loadingmirrorspeedsfromcachedhostfile *base:mirrors.zju.edu.cn *extras:mirrors.aliyun.com *updates:mirrors.aliyun.com InstalledPackages MySQL-python.x86_641.2.3-0.3.c1.1.el6@base mysql-libs.x86_645.1.73-8.el6_8@anaconda-CentOS-201703281317.x86_64/6.9
2、卸载已安装的mysql，建议使用yum命令，因为yum命令可以自动删除与mysql相关的依赖；如果使用rpm命令，则还需要手动去删除和mysql相关的文件，比较麻烦

3、用whereis命令查找mysql相关的文件，因为步骤2用yum来卸载，所以mysql被清理得很干净；如果使用rpm将会很麻烦，有很多的文件需要手动清除
[root@cdh1zjl]#whereismysql mysql:
4、查看系统中的mysql安装包
[root@cdh1zjl]#yumlistmysql* Loadedplugins:fastestmirror,refresh-packagekit,security Loadingmirrorspeedsfromcachedhostfile *base:mirrors.zju.edu.cn *extras:mirrors.aliyun.com *updates:mirrors.aliyun.com AvailablePackages MySQL-python.x86_641.2.3-0.3.c1.1.el6base mysql.x86_645.1.73-8.el6_8base mysql-bench.x86_645.1.73-8.el6_8base mysql-connector-java.noarch1:5.1.17-6.el6base mysql-connector-odbc.x86_645.1.5r1144-7.el6base mysql-devel.i6865.1.73-8.el6_8base mysql-devel.x86_645.1.73-8.el6_8base mysql-embedded.i6865.1.73-8.el6_8base mysql-embedded.x86_645.1.73-8.el6_8base mysql-embedded-devel.i6865.1.73-8.el6_8base mysql-embedded-devel.x86_645.1.73-8.el6_8base mysql-libs.i6865.1.73-8.el6_8base mysql-libs.x86_645.1.73-8.el6_8base mysql-server.x86_645.1.73-8.el6_8base mysql-test.x86_645.1.73-8.el6_8base
5、选择mysql-server来安装
[root@cdh1zjl]#yuminstallmysql-server Loadedplugins:fastestmirror,refresh-packagekit,security SettingupInstallProcess Loadingmirrorspeedsfromcachedhostfile *base:mirrors.zju.edu.cn *extras:mirrors.aliyun.com *updates:mirrors.aliyun.com ResolvingDependencies -->Runningtransactioncheck --->Packagemysql-server.x86_640:5.1.73-8.el6_8willbeinstalled -->ProcessingDependency:mysql=5.1.73-8.el6_8forpackage:mysql-server-5.1.73-8.el6_8.x86_64 -->ProcessingDependency:perl-DBIforpackage:mysql-server-5.1.73-8.el6_8.x86_64 -->ProcessingDependency:perl-DBD-MySQLforpackage:mysql-server-5.1.73-8.el6_8.x86_64 -->ProcessingDependency:perl(DBI)forpackage:mysql-server-5.1.73-8.el6_8.x86_64 -->ProcessingDependency:libmysqlclient_r.so.16(libmysqlclient_16)(64bit)forpackage:mysql-server-5.1.73-8.el6_8.x86_64 -->ProcessingDependency:libmysqlclient.so.16(libmysqlclient_16)(64bit)forpackage:mysql-server-5.1.73-8.el6_8.x86_64 -->ProcessingDependency:libmysqlclient_r.so.16()(64bit)forpackage:mysql-server-5.1.73-8.el6_8.x86_64 -->ProcessingDependency:libmysqlclient.so.16()(64bit)forpackage:mysql-server-5.1.73-8.el6_8.x86_64 -->Runningtransactioncheck --->Packagemysql.x86_640:5.1.73-8.el6_8willbeinstalled --->Packagemysql-libs.x86_640:5.1.73-8.el6_8willbeinstalled --->Packageperl-DBD-MySQL.x86_640:4.013-3.el6willbeinstalled --->Packageperl-DBI.x86_640:1.609-4.el6willbeinstalled -->FinishedDependencyResolution DependenciesResolved ================================================================================================================================================================================================================= PackageArchVersionRepositorySize ================================================================================================================================================================================================================= Installing: mysql-serverx86_645.1.73-8.el6_8base8.6M Installingfordependencies: mysqlx86_645.1.73-8.el6_8base895k mysql-libsx86_645.1.73-8.el6_8base1.2M perl-DBD-MySQLx86_644.013-3.el6base134k perl-DBIx86_641.609-4.el6base705k TransactionSummary ================================================================================================================================================================================================================= Install5Package(s) Totaldownloadsize:12M Installedsize:33M Isthisok[y/N]: 6、选择y继续安装 Isthisok[y/N]:y DownloadingPackages: (1/5):mysql-5.1.73-8.el6_8.x86_64.rpm|895kB00:00 (2/5):mysql-libs-5.1.73-8.el6_8.x86_64.rpm|1.2MB00:00 (3/5):mysql-server-5.1.73-8.el6_8.x86_64.rpm|8.6MB00:02 (4/5):perl-DBD-MySQL-4.013-3.el6.x86_64.rpm|134kB00:00 (5/5):perl-DBI-1.609-4.el6.x86_64.rpm|705kB00:00 ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Total2.2MB/s|12MB00:05 Runningrpm_check_debug RunningTransactionTest TransactionTestSucceeded RunningTransaction Installing:mysql-libs-5.1.73-8.el6_8.x86_641/5 Installing:perl-DBI-1.609-4.el6.x86_642/5 Installing:perl-DBD-MySQL-4.013-3.el6.x86_643/5 Installing:mysql-5.1.73-8.el6_8.x86_644/5 Installing:mysql-server-5.1.73-8.el6_8.x86_645/5 Verifying:perl-DBD-MySQL-4.013-3.el6.x86_641/5 Verifying:mysql-libs-5.1.73-8.el6_8.x86_642/5 Verifying:mysql-server-5.1.73-8.el6_8.x86_643/5 Verifying:mysql-5.1.73-8.el6_8.x86_644/5 Verifying:perl-DBI-1.609-4.el6.x86_645/5 Installed: mysql-server.x86_640:5.1.73-8.el6_8 DependencyInstalled: mysql.x86_640:5.1.73-8.el6_8mysql-libs.x86_640:5.1.73-8.el6_8perl-DBD-MySQL.x86_640:4.013-3.el6perl-DBI.x86_640:1.609-4.el6 Complete!
7、启动mysql服务

8、连接一下试一下，直接mysql然后\q关闭连接

9、设置mysql开机启动
[root@cdh1zjl]#chkconfigmysqldon
10、开启3306端口，并保存
[root@cdh1zjl]#/sbin/iptables-IINPUT-ptcp--dport3306-jACCEPT [root@cdh1zjl]#/etc/rc.d/init.d/iptablessave
11、连接mysql设置密码
