1、确认mysql是否已安装，有下面的代码可知
[[email protected] zjl]# yum list installed mysql* Loaded plugins: fastestmirror, refresh-packagekit, security Loading mirror speeds from cached hostfile * base: mirrors.zju.edu.cn * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com Installed Packages MySQL-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
[[email protected] zjl]# yum remove MySQL-python.x86_64 mysql-libs.x86_64 Loaded plugins: fastestmirror, refresh-packagekit, security Setting up Remove Process Resolving 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 Resolution Dependencies 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 M Removing 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 k Transaction Summary ==================================================================== Remove 13 Package(s) Installed size: 86 M Is this ok [y/N]: y Downloading Packages: Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Warning: 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
[[email protected] zjl]# whereis mysql mysql:
4、查看系统中的mysql安装包
[[email protected] zjl]# yum list mysql* Loaded plugins: fastestmirror, refresh-packagekit, security Loading mirror speeds from cached hostfile * base: mirrors.zju.edu.cn * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com Available Packages MySQL-python.x86_64 1.2.3-0.3.c1.1.el6 base mysql.x86_64 5.1.73-8.el6_8 base mysql-bench.x86_64 5.1.73-8.el6_8 base mysql-connector-java.noarch 1:5.1.17-6.el6 base mysql-connector-odbc.x86_64 5.1.5r1144-7.el6 base mysql-devel.i686 5.1.73-8.el6_8 base mysql-devel.x86_64 5.1.73-8.el6_8 base mysql-embedded.i686 5.1.73-8.el6_8 base mysql-embedded.x86_64 5.1.73-8.el6_8 base mysql-embedded-devel.i686 5.1.73-8.el6_8 base mysql-embedded-devel.x86_64 5.1.73-8.el6_8 base mysql-libs.i686 5.1.73-8.el6_8 base mysql-libs.x86_64 5.1.73-8.el6_8 base mysql-server.x86_64 5.1.73-8.el6_8 base mysql-test.x86_64 5.1.73-8.el6_8 base
5、选择mysql-server来安装
[[email protected] zjl]# yum install mysql-server Loaded plugins: fastestmirror, refresh-packagekit, security Setting up Install Process Loading mirror speeds from cached hostfile * base: mirrors.zju.edu.cn * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com Resolving Dependencies --> Running transaction check ---> Package mysql-server.x86_64 0:5.1.73-8.el6_8 will be installed --> Processing Dependency: mysql = 5.1.73-8.el6_8 for package: mysql-server-5.1.73-8.el6_8.x86_64 --> Processing Dependency: perl-DBI for package: mysql-server-5.1.73-8.el6_8.x86_64 --> Processing Dependency: perl-DBD-MySQL for package: mysql-server-5.1.73-8.el6_8.x86_64 --> Processing Dependency: perl(DBI) for package: mysql-server-5.1.73-8.el6_8.x86_64 --> Processing Dependency: libmysqlclient_r.so.16(libmysqlclient_16)(64bit) for package: mysql-server-5.1.73-8.el6_8.x86_64 --> Processing Dependency: libmysqlclient.so.16(libmysqlclient_16)(64bit) for package: mysql-server-5.1.73-8.el6_8.x86_64 --> Processing Dependency: libmysqlclient_r.so.16()(64bit) for package: mysql-server-5.1.73-8.el6_8.x86_64 --> Processing Dependency: libmysqlclient.so.16()(64bit) for package: mysql-server-5.1.73-8.el6_8.x86_64 --> Running transaction check ---> Package mysql.x86_64 0:5.1.73-8.el6_8 will be installed ---> Package mysql-libs.x86_64 0:5.1.73-8.el6_8 will be installed ---> Package perl-DBD-MySQL.x86_64 0:4.013-3.el6 will be installed ---> Package perl-DBI.x86_64 0:1.609-4.el6 will be installed --> Finished Dependency Resolution Dependencies Resolved ================================================================================================================================================================================================================= Package Arch Version Repository Size ================================================================================================================================================================================================================= Installing: mysql-server x86_64 5.1.73-8.el6_8 base 8.6 M Installing for dependencies: mysql x86_64 5.1.73-8.el6_8 base 895 k mysql-libs x86_64 5.1.73-8.el6_8 base 1.2 M perl-DBD-MySQL x86_64 4.013-3.el6 base 134 k perl-DBI x86_64 1.609-4.el6 base 705 k Transaction Summary ================================================================================================================================================================================================================= Install 5 Package(s) Total download size: 12 M Installed size: 33 M Is this ok [y/N]:
6、选择y继续安装

7、启动mysql服务
[[email protected] zjl]# service mysqld start Initializing MySQL database: Installing MySQL system tables... OK Filling help tables... OK To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system PLEASE 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_installation which will also give you the option of removing the test databases and anonymous user created by default. This is strongly 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.pl cd /usr/mysql-test ; perl mysql-test-run.pl Please 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
[[email protected] zjl]# mysql Welcome to the MySQL monitor. Commands end with ; or \g.

Type ‘\c‘ to clear the current input statement. mysql> \q Bye
9、设置mysql开机启动
[[email protected] zjl]# chkconfig mysqld on
10、开启3306端口，并保存
[[email protected] zjl]# /sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT [[email protected] zjl]# /etc/rc.d/init.d/iptables save
11、连接mysql设置密码
[[email protected] zjl]# mysql Welcome to the MySQL monitor. Commands end with ; or \g.
