大家好，感谢邀请，今天来为大家分享一下centos安装mysql详细步骤的问题，以及和centos7安装配置的一些困惑，大家要是还不太明白的话，也没有关系，因为接下来将为大家分享，希望可以帮助到大家，解决大家的问题，下面就开始吧！
一、centos安装mysql数据库的方法
1、首先下载MySQL的安装文件，我这里安装的是MySQL5.1.7版本的，
进入安装包所在文件夹，执行命令 rpm-ivh MySQL-server-5.1.7-0.i386.rpm安装MySQL服务器。
如果报了与原先版本冲突的话，就执行rpm-qa|grep-i mysql命令，会显示已安装的Mysql版本,我的显示mysql-libs-5.1.61-4.el6.i686
这时如果有的话就强制删除：rpm-e--nodeps mysql-libs-5.1.61-4.el6.i686（因为有包依赖，所以要强制删除）

这时候再执行rpm-ivh MySQL-server-5.1.7-0.i386.rpm安装即可安装成功。
我这里安装成功了，但是mysql服务无法启动，总是启动失败，后来百度了一下，是因为selinux的原因，只要将selinux关闭就OK了。
关闭selinux：vi/etc/selinux/config将SELINUX=enforcing改成SELINUX=disabled然后重启
关闭selinux之后还是无法启动mysql服务，因为安装的mysql所有者是root，在安装mysql的时候会创建一个用户mysql，只要将/var/lib/mysql
的所有者改为mysql就OK了，执行命令chown-R mysql:mysql/var/lib/mysql
现在执行service mysql start终于可以启动mysql服务了。
执行命令rpm-ivh MySQL-client-5.1.7-0.i386.rpm进行安装。
成功安装MySQL后将sql文件导入到数据库，步骤如下：
1、先创建数据库：create database test注：test是创建数据库的名称
2、再切换到当前数据库：use test
3、再输入：/./root/test.sql或 souce/root/test.sql
按照以上步骤就可以将备份的sql脚本导入到linux中的数据库中去。
二、centos7怎么安装mysql
1、Centos 7默认不支持mysql（都是因为钱），所以centos 7默认支持的是mariadb
MariaDB数据库管理系统是MySQL的一个分支，主要由开源社区在维护，采用GPL授权许可 MariaDB的目的是完全兼容MySQL，包括API和命令行，使之能轻松成为MySQL的代替品。在存储引擎方面，使用XtraDB来代替MySQL的InnoDB。 MariaDB由MySQL的创始人Michael Widenius主导开发，他早前曾以10亿美元的价格，将自己创建的公司MySQL AB卖给了SUN，此后，随着SUN被甲骨文收购，MySQL的所有权也落入Oracle的手中。MariaDB名称来自Michael Widenius的女儿Maria的名字。
说到这，我个人强烈推荐大家开始学习MariaDB,当然由于我们一些项目还是要用mysql的，所以不能放弃。真不难学。
接下来我讲一下centos 7对mysql的安装过程
1、如果一定要在centos 7上安装mysql，需要卸载MariaDB，否则会冲突。
2、执行这个命令：rpm-qa| grep mariadb
3、这时会出现一些列表，都是mariadb的包，接下来我们要干掉
4、执行如下命令rpm-e–nodeps mariadb-libs-XXXXX.x86_64（注意我这里的xxxx,要根据第三步出现的列表，挨个干)
5、干完后，就可以安装mysql了。
6、去度娘搜索mysql的rpm包，一大把。我用的是5.6.22.(找不到的，问我要)
这里需要安装至少2个，1个是mysql-server-xxxx.rpm（这个就是服务端),还有一个是mysql-client-xxxx.rpm(这个是客户端，不想装？不装的话你没法初始化root密码，求懂)
7、执行 rpm-ivh“上面两个文件名”
9、然后执行:service mysql start(如果OK，说明装好了)
10、再然后执行：service mysql stop(不要问为什么，因为默认root没有密码，你进不去,所以接下来我们要绕过密码登录)
11、执行这个命令:mysqld_safe–user=mysql–skip-grant-tables–skip-networking& mysql-u root mysql(也就是，老子不用密码直接登录，这时mysql服务必须关闭状态)
12、然后执行这个命令：UPDATE user SET Password=PASSWORD(‘XXXXX’) where USER=’root’;这里就是对root账号初始化密码，xxx自行改，不要忘了。忘掉的话就要用第11步初始化（谁说没有密码就不能进mysql?）
13、然后执行 flush privileges;（注意不要忘记最后的分号，必须有，不要问为什么)
14、然后输入quit;退出mysql客户端。
15、重新启动mysql,命令：service mysql start
16、然后用root账号登录命令:mysql-u root-p(接下来会提示你输入密码，此时屏幕不可见，不要以为死机了)
17、这时随便执行一个sql,譬如 show databases;
18、这时会报错，大约是You must SET PASSWORD before executing this statement.其实就是我们常见的：第一次登录需要改密码,
19、那我们就改一改吧，反正不会怀孕
20、执行 SET PASSWORD= PASSWORD(‘xxxx’);注意分号，也可以把密码跟上面搞得一样。
21、然后再去执行一些sql，看看对不对。对的话quit;
22、最后，我们最好吧mysql重启一下. service mysql restart
23、然后配置远程可以连接（注意刚才我们都是在本机操作的哦~~~~）
24、依然mysql-u root-p输入密码后登入
25、执行：GRANT ALL PRIVILEGES ON*.* TO‘root’@’%’ IDENTIFIED BY‘这里填你的密码’ WITH GRANT OPTION;(这里root@后面的百分号代表全宇宙都可以连接你的mysql,只要知道密码),如果是仅仅允许某个IP连接，那么把这个百分号换成某个ip即可
好吧，OK了。接下来大家可以用navicate去连接啦
三、centos mysql 安装及配置
Mysql具有简单易学、体积小等优点，深受编程开发初学者的喜爱
Centos 6.6下安装Mysql很简单， yum list mysql-server
当只有一个时候就可以直接 yum install mysql-server进行安装
过程中选择Y继续安装，最后安装成功
先启动Mysql服务 service mysqld start
连接一下试一下，直接 mysql然后\q关闭连接
设置Mysql开机启动 chkconfig mysqld on
开启3306端口并保存/sbin/iptables-I INPUT-p tcp--dport 3306-j ACCEPT/etc/rc.d/init.d/iptables save
连接mysql数据库设置密码 use mysql; update user set password=password('密码') where user='root'; flush privileges;
设置Mysql远程访问 grant all privileges on*.* to'root'@'%' identified by'123456' with grant option;
找一个配置文件，复制到/etc/目录，命名为my.cnf（有时候没有my.cnf） cp/usr/share/doc/mysql-server-5.1.73/my-medium.cnf/etc/my.cnf
vim my.cnf在[client]和[mysqld]下面都添加上 default-character-set=utf8
最后重新启动服务就可以了 service mysqld restart
