centos 6.9安装mysql的详细教程

1、确认mysql/' target='_blank'>mysql是否已安装，有下面的代码可知

[root@cdh1 zjl]# yum list installed MySQL*Loaded plugins: fastestmirror, refresh-packagekit, securityLoading mirror speeds from cached hostfile * base: mirrors.zju.edu.cn * extras: mirrors.aliyun.com * updates: mirrors.aliyun.comInstalled PackagesMySQL-python/' target='_blank'>python.x86_64 1.2.3-0.3.c1.1.el6 @base      mysql-libs.x86_64 5.1.73-8.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

[root@cdh1 zjl]# yum remove MySQL-Python.x86_64 mysql-libs.x86_64Loaded plugins: fastestmirror, refresh-packagekit, securitySetting up Remove ProcessResolving Dependencies--> Running transaction check---> Package MySQL-python.x86_64 0:1.2.3-0.3.c1.1.el6 will be erased--> Processing Dependency: MySQL-python for package: cloudera-manager-agent-5.11.1-1.cm5111.p0.9.el6.x86_64---> Package mysql-libs.x86_64 0:5.1.73-8.el6_8 will be erased--> Processing Dependency: libmysqlclient.so.16()(64bit) for package: 2:postfix-2.6.6-8.el6.x86_64--> Processing Dependency: libmysqlclient.so.16(libmysqlclient_16)(64bit) for package: 2:postfix-2.6.6-8.el6.x86_64--> Processing Dependency: mysql-libs for package: 2:postfix-2.6.6-8.el6.x86_64--> Running transaction check---> Package cloudera-manager-agent.x86_64 0:5.11.1-1.cm5111.p0.9.el6 will be erased---> Package postfix.x86_64 2:2.6.6-8.el6 will be erased--> Processing Dependency: /usr/sbin/sendmail for package: redhat-lsb-core-4.0-7.el6.centos.x86_64--> Processing Dependency: /usr/sbin/sendmail for package: cronie-1.4.4-16.el6_8.2.x86_64--> Running transaction check---> Package cronie.x86_64 0:1.4.4-16.el6_8.2 will be erased--> Processing Dependency: cronie = 1.4.4-16.el6_8.2 for package: cronie-anacron-1.4.4-16.el6_8.2.x86_64---> Package redhat-lsb-core.x86_64 0:4.0-7.el6.centos will be erased--> Processing Dependency: redhat-lsb-core(x86-64) = 4.0 for package: redhat-lsb-printing-4.0-7.el6.centos.x86_64--> Processing Dependency: redhat-lsb-core(x86-64) = 4.0-7.el6.centos for package: redhat-lsb-4.0-7.el6.centos.x86_64--> Processing Dependency: redhat-lsb-core(x86-64) = 4.0 for package: redhat-lsb-graphics-4.0-7.el6.centos.x86_64--> Running transaction check---> Package cronie-anacron.x86_64 0:1.4.4-16.el6_8.2 will be erased---> Package redhat-lsb.x86_64 0:4.0-7.el6.centos will be erased--> Processing Dependency: redhat-lsb(x86-64) = 4.0-7.el6.centos for package: redhat-lsb-compat-4.0-7.el6.centos.x86_64---> Package redhat-lsb-graphics.x86_64 0:4.0-7.el6.centos will be erased---> Package redhat-lsb-printing.x86_64 0:4.0-7.el6.centos will be erased--> Running transaction check---> Package redhat-lsb-compat.x86_64 0:4.0-7.el6.centos will be erased--> Processing Dependency: /etc/cron.d for package: crontabs-1.10-33.el6.noarch--> Processing Dependency: /etc/cron.d for package: sysstat-9.0.4-33.el6.x86_64--> Restarting Dependency Resolution with new changes.--> Running transaction check---> Package crontabs.noarch 0:1.10-33.el6 will be erased---> Package sysstat.x86_64 0:9.0.4-33.el6 will be erased--> Finished Dependency ResolutionDependencies Resolved==================================================================== Package    Arch Version     Repository                Size====================================================================Removing: MySQL-python   x86_64 1.2.3-0.3.c1.1.el6  @base 246 k mysql-libs    x86_64 5.1.73-8.el6_8   @anaconda-CentOS-201703281317.x86_64/6.9                4.0 MRemoving for dependencies: cloudera-manager-agent x86_64 5.11.1-1.cm5111.p0.9.el6 @/cloudera-manager-agent-5.11.1-1.cm5111.p0.9.el6.x86_64                71 M cronie     x86_64 1.4.4-16.el6_8.2   @anaconda-CentOS-201703281317.x86_64/6.9                174 k cronie-anacron   x86_64 1.4.4-16.el6_8.2   @anaconda-CentOS-201703281317.x86_64/6.9                43 k crontabs    noarch 1.10-33.el6    @anaconda-CentOS-201703281317.x86_64/6.9                2.4 k postfix    x86_64 2:2.6.6-8.el6   @anaconda-CentOS-201703281317.x86_64/6.9                9.7 M redhat-lsb    x86_64 4.0-7.el6.centos   @anaconda-CentOS-201703281317.x86_64/6.9                0.0  redhat-lsb-compat  x86_64 4.0-7.el6.centos   @anaconda-CentOS-201703281317.x86_64/6.9                0.0  redhat-lsb-core  x86_64 4.0-7.el6.centos   @anaconda-CentOS-201703281317.x86_64/6.9                22 k redhat-lsb-graphics x86_64 4.0-7.el6.centos   @anaconda-CentOS-201703281317.x86_64/6.9                0.0  redhat-lsb-printing x86_64 4.0-7.el6.centos   @anaconda-CentOS-201703281317.x86_64/6.9                0.0  sysstat    x86_64 9.0.4-33.el6    @anaconda-CentOS-201703281317.x86_64/6.9                826 kTransaction Summary====================================================================Remove  13 Package(s)Installed size: 86 MIs this ok [y/N]: yDownloading Packages:Running rpm_check_debugRunning Transaction TestTransaction Test SucceededRunning TransactionWarning: RPMDB altered outside of yum.

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@cdh1 zjl]# whereis mysqlmysql:

4、查看系统中的mysql安装包

[root@cdh1 zjl]# yum list mysql*Loaded plugins: fastestmirror, refresh-packagekit, securityLoading mirror speeds from cached hostfile * base: mirrors.zju.edu.cn * extras: mirrors.aliyun.com * updates: mirrors.aliyun.comAvailable PackagesMySQL-python.x86_64                      1.2.3-0.3.c1.1.el6                    basemysql.x86_64                        5.1.73-8.el6_8                     basemysql-bench.x86_64                       5.1.73-8.el6_8                     basemysql-connector-java.noarch                    1:5.1.17-6.el6                     basemysql-connector-odbc.x86_64                    5.1.5r1144-7.el6                     basemysql-devel.i686                       5.1.73-8.el6_8                     basemysql-devel.x86_64                       5.1.73-8.el6_8                     basemysql-embedded.i686                      5.1.73-8.el6_8                     basemysql-embedded.x86_64                      5.1.73-8.el6_8                     basemysql-embedded-devel.i686                     5.1.73-8.el6_8                     basemysql-embedded-devel.x86_64                    5.1.73-8.el6_8                     basemysql-libs.i686                       5.1.73-8.el6_8                     basemysql-libs.x86_64                       5.1.73-8.el6_8                     basemysql-server.x86_64                      5.1.73-8.el6_8                     basemysql-test.x86_64                       5.1.73-8.el6_8                     base

5、选择mysql-server来安装

7、启动mysql服务

[root@cdh1 zjl]# service mysqld startInitializing MySQL database: Installing MySQL system tables...OKFilling help tables...OKTo start mysqld at boot time you have to copysupport-files/mysql.server to the right place for your systemPLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !To do so, start the server, then issue the following commands:/usr/bin/mysqladmin -u root password 'new-password'/usr/bin/mysqladmin -u root -h cdh1.zjl.com password 'new-password'Alternatively you can run:/usr/bin/mysql_secure_installationwhich will also give you the option of removing the testdatabases and anonymous user created by default. This isstrongly recommended for production servers.See the manual for more instructions.You can start the MySQL daemon with:cd /usr ; /usr/bin/mysqld_safe &You can test the MySQL daemon with mysql-test-run.plcd /usr/mysql-test ; perl mysql-test-run.plPlease report any problems with the /usr/bin/mysqlbug script!               [ OK ]Starting mysqld:           [ OK ]

8、连接一下试一下，直接mysql然后\q关闭连接

[root@cdh1 zjl]# mysqlWelcome to the MySQL monitor. Commands end with ; or \g.Your MySQL connection id is 2Server version: 5.1.73 Source distributionCopyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved.Oracle is a registered trademark of Oracle Corporation and/or itsaffiliates. Other names may be trademarks of their respectiveowners.Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.mysql> \qBye

9、设置mysql开机启动

[root@cdh1 zjl]# chkconfig mysqld on

10、开启3306端口，并保存

[root@cdh1 zjl]# /sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT[root@cdh1 zjl]# /etc/rc.d/init.d/iptables save

11、连接mysql设置密码
