MySQL客户端安装

# MySQL客户端安装 #

背景:服务器容器中部署了MySQL数据库或者使用阿里云的RDS数据库，由于本地服务器没有安装客户端无法连接数据库做备份/还原，本文只是安装MySQL的客户端，不包括数据库。

## 下载rpm包 ##

https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-community-libs-5.7.25-1.el7.x86_64.rpm
    https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-community-common-5.7.25-1.el7.x86_64.rpm
    https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-community-client-5.7.25-1.el7.x86_64.rpm

也可自行去MySQL官网下载:[官网地址][Link 1]  
MySQL官网有很多不同的版本，我选择的是\*\*MySQL Community Server \*\*(社区服务器版本)  
选择的MySQL是5.7版本，当前最新版本是8.0  
以下为下载说明

## 安装rpm包 ##

三者的版本必须一致，不能一个5.7，其他的8.0。  
三者直接是有依赖顺序的，必须按顺序安装，如遇报错，请参考下面的

[root@d69 test]# rpm -ivh mysql-community-common-5.7.25-1.el7.x86_64.rpm
    [root@d69 test]# rpm -ivh mysql-community-libs-5.7.25-1.el7.x86_64.rpm  
    [root@d69 test]# rpm -ivh  mysql-community-client-5.7.25-1.el7.x86_64.rpm

## 测试MySQL客户端是否安装 ##

[root@d69 test]# mysql --help
    mysql  Ver 14.14 Distrib 5.7.25, for Linux (x86_64) using  EditLine wrapper

## 踩坑之旅 ##

## rpm -ivh mysql-community-libs-5.7.25-1.el7.x86\_64.rpm 安装时报错 ##

以下为报错信息

[root@d69 test]# rpm -ivh mysql-community-client-8.0.15-1.el7.x86_64.rpm
    warning: mysql-community-client-8.0.15-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
    error: Failed dependencies:
            mysql-community-libs(x86-64) >= 8.0.0 is needed by mysql-community-client-8.0.15-1.el7.x86_64

原因和解决:  
如上的报错，由于centos 7默认是mariadb数据库，再去安装mysql之前要先下载mariadb

[root@d69 test]#  rpm -qa | grep mariadb
    mariadb-devel-5.5.60-1.el7_5.x86_64
    mariadb-libs-5.5.60-1.el7_5.x86_64
    [root@d69 test]# rpm -e mariadb-libs-5.5.60-1.el7_5.x86_64
    error: Failed dependencies:
            libmysqlclient.so.18()(64bit) is needed by (installed) mariadb-devel-1:5.5.60-1.el7_5.x86_64
            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

    # 由于存在依赖关系，强制卸载
    [root@d69 test]# rpm -e --nodeps mariadb-libs-5.5.60-1.el7_5.x86_64
