在centos7中使用yum安装mysql数据库并使用navic

1、安装

1.查看yum列表，发现没有mysql

[root@server-mysql src]# yum list mysql
    已加载插件：fastestmirror
    Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast
    Loading mirror speeds from cached hostfile
     * base: centos.ustc.edu.cn
     * extras: centos.ustc.edu.cn
     * updates: centos.ustc.edu.cn
    错误：没有匹配的软件包可以列出

2.使用wget下载一个mysql的repo源

[root@server-mysql src]# wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
    -bash: wget: 未找到命令

3.发现wget也没有，那就安装一个wget

[root@server-mysql src]# yum list wget
    已加载插件：fastestmirror
    Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast
    Loading mirror speeds from cached hostfile
     * base: centos.ustc.edu.cn
     * extras: centos.ustc.edu.cn
     * updates: centos.ustc.edu.cn
    可安装的软件包
    wget.x86_64       1.14-15.el7_4.1     base

[root@server-mysql src]# yum -y install wget.x86_64

......

    已安装:
      wget.x86_64 0:1.14-15.el7_4.1

    完毕！

4.在次下载mysql的repo源

[root@server-mysql src]# wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
    --2018-09-08 14:45:20--  http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
    正在解析主机 repo.mysql.com (repo.mysql.com)... 104.124.241.153
    正在连接 repo.mysql.com (repo.mysql.com)|104.124.241.153|:80... 已连接。
    已发出 HTTP 请求，正在等待回应... 200 OK
    长度：6140 (6.0K) [application/x-redhat-package-manager]
    正在保存至: “mysql-community-release-el7-5.noarch.rpm”

    100%[========================================================>] 6,140       --.-K/s 用时 0.001s

    2018-09-08 14:45:20 (8.39 MB/s) - 已保存 “mysql-community-release-el7-5.noarch.rpm” [6140/6140])

5.用命令查看当前目录，已经下载好了

[root@server-mysql src]# ll | grep mysql
    -rw-r--r--. 1 root root 6140 11月 12 2015 mysql-community-release-el7-5.noarch.rpm

6.安装一下

[root@server-mysql src]# rpm -ivh mysql-community-release-el7-5.noarch.rpm
    准备中...                          ################################# [100%]
    正在升级/安装...
       1:mysql-community-release-el7-5    ################################# [100%]

7.再次查看yum列表，发现已经有mysql的包了

[root@server-mysql src]# yum list mysql
    已加载插件：fastestmirror
    mysql-connectors-community                               | 2.5 kB  00:00:00
    mysql-tools-community                                    | 2.5 kB  00:00:00
    mysql56-community                                        | 2.5 kB  00:00:00
    (1/3): mysql-connectors-community/x86_64/primary_db      |  26 kB  00:00:00
    (2/3): mysql-tools-community/x86_64/primary_db           |  45 kB  00:00:00

8.执行安装(会替换自带的mariadb库)

[root@server-mysql src]# yum -y install mysql-server
    已加载插件：fastestmirror
.......

    已安装:
      mysql-community-libs.x86_64 0:5.6.41-2.el7                                        mysql-community-server.x86_64 0:5.6.41-2.el7

    作为依赖被安装:
      mysql-community-client.x86_64 0:5.6.41-2.el7           mysql-community-common.x86_64 0:5.6.41-2.el7           net-tools.x86_64 0:2.0-0.22.20131004git.el7
      perl-Compress-Raw-Bzip2.x86_64 0:2.061-3.el7           perl-Compress-Raw-Zlib.x86_64 1:2.061-4.el7            perl-DBI.x86_64 0:1.627-4.el7
      perl-Data-Dumper.x86_64 0:2.145-3.el7                  perl-IO-Compress.noarch 0:2.061-2.el7                  perl-Net-Daemon.noarch 0:0.48-5.el7
      perl-PlRPC.noarch 0:0.2020-14.el7

    替代:
      mariadb-libs.x86_64 1:5.5.56-2.el7

    完毕！
