linux上安装MySQL
一、下载mysql服务软件包
地址：https://dev.mysql.com/downloads/mysql/
rpm package:是某个特定的包，比如server,client,devle等
rpm bundle：是该版本所有包的集合
Compressed TAR Archive，是源码，必须用源码方式安装
Compatibility Libraries：兼容库
Shared Libraries：共享库
Development Libraries：开发库
Test Suite：测试套件
Client Utilities：客户端工具
下载时注意选则好对应的版本
二、安装(contos7.2)
（1）rpm -ivh mysql-community-libs-8.0.18-1.el7.x86_64
报错信息：
error: Failed dependencies:
mariadb-libs is obsoleted by mysql-community-libs-8.0.18-1.el7.x86_64
原因：mariadb-libs和 mysql-community-libs冲突
解决办法：卸载mariadb-libs
a.查询mariadb-libs的包名
[root@izm5e8nyz28va3a786y465z src]# rpm -qa |grep mariadb
mariadb-libs-5.5.64-1.el7.x86_64
b.卸载该包
[root@izm5e8nyz28va3a786y465z src]# rpm -ev mariadb-libs-5.5.64-1.el7.x86_64
error: Failed dependencies:
libmysqlclient.so.18()(64bit) is needed by (installed) postfix-2:2.10.1-7.el7.x86_64
libmysqlclient.so.18(libmysqlclient_18)(64bit) is needed by (installed) postfix-2:2.10.1-7.el7.x86_64
报错原因：postfix是mariadb 的依赖包，要先卸载它
[root@izm5e8nyz28va3a786y465z src]# rpm -qa |grep postfix
postfix-2.10.1-7.el7.x86_64
[root@izm5e8nyz28va3a786y465z src]# rpm -ev postfix-2.10.1-7.el7.x86_64
error: Failed dependencies:
/usr/sbin/sendmail is needed by (installed) redhat-lsb-core-4.1-27.el7.centos.1.x86_64
[root@izm5e8nyz28va3a786y465z src]# rpm -qa |grep redhat-lsb

redhat-lsb-submod-security-4.1-27.el7.centos.1.x86_64
[root@izm5e8nyz28va3a786y465z src]# rpm -ev redhat-lsb-core-4.1-27.el7.centos.1.x86_64

Preparing packages...
postfix-2:2.10.1-7.el7.x86_64
上述步骤成功卸载掉mariadb-libs的依赖
[root@izm5e8nyz28va3a786y465z src]# rpm -ev mariadb-libs-5.5.64-1.el7.x86_64
Preparing packages...
mariadb-libs-1:5.5.64-1.el7.x86_64
继续安装：
[root@izm5e8nyz28va3a786y465z src]# rpm -ivh mysql-community-libs-8.0.18-1.el7.x86_64.rpm

查询到4个相关的依赖包，只需安装libaio.x86_64 libaio-devel.x86_64
yum -y install libaio.x86_64 libaio-devel.x86_64

至此Mysql安装成功
小结：1. 卸载掉冲突组件 mariadb
rpm -ev redhat-lsb-core-4.1-27.el7.centos.1.x86_64 postfix-2.10.1-7.el7.x86_64 mariadb-libs-5.5.64-1.el7.x86_64
2.安装相关依赖：
yum -y install openssl openssl-devel libaio libaio-devel
