vmware12下的centos7 linux 安装 mysql5.17数据库

1、root 登录linux

2、上传cd /opt   mysql-5.7.16-1.el7.x86_64.rpm-bundle.tar

3、进入cd /opt 并创建文件夹 mkdir work、mkdir program

4、进入cd /opt解压文件夹，tar xvf mysql-5.7.16-1.el7.x86_64.rpm-bundle.tar -C /opt/work/program

mysql-community-client-5.7.16-1.el7.x86_64.rpm

mysql-community-common-5.7.16-1.el7.x86_64.rpm

mysql-community-devel-5.7.16-1.el7.x86_64.rpm

mysql-community-embedded-5.7.16-1.el7.x86_64.rpm

mysql-community-embedded-compat-5.7.16-1.el7.x86_64.rpm

mysql-community-embedded-devel-5.7.16-1.el7.x86_64.rpm

mysql-community-libs-5.7.16-1.el7.x86_64.rpm

mysql-community-libs-compat-5.7.16-1.el7.x86_64.rpm

mysql-community-minimal-debuginfo-5.7.16-1.el7.x86_64.rpm

mysql-community-server-5.7.16-1.el7.x86_64.rpm

mysql-community-server-minimal-5.7.16-1.el7.x86_64.rpm

mysql-community-test-5.7.16-1.el7.x86_64.rpm

5、进入cd /opt/work/program

6、创建mysql用户

      #groupadd mysql

      #useradd -r -g mysql mysql

      #passwd mysql 

      #usermod -d /opt/work/program mysql

7、执行 rpm -ivh mysql-community-common-5.7.16-1.el7.x86_64.rpm

报错：arning: mysql-community-common-5.7.16-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

解决方法：#yum remove mysql mysql-server mysql-libs compat-mysql51

8、执行#rpm --import /etc/pki/rpm-gpg/RPM*

9、#rpm -ivh mysql-community-common-5.7.16-1.el7.x86_64.rpm  --nosignature

10、#rpm -ivh mysql-community-libs-5.7.16-1.el7.x86_64.rpm  --nosignature

11、#rpm -ivh mysql-community-client-5.7.16-1.el7.x86_64.rpm  --nosignature

12、#rpm -ivh mysql-community-server-5.7.16-1.el7.x86_64.rpm  --nosignature

13、在 Liunx 系统中，为了保证数据库目录为与文件的所有者为 mysql 登陆用户，如果你是以 root 身份运行 mysql 服务，需要执行下面的命令初始化

        # mysqld --initialize --user=mysql

14查看是否安装

#rpm -qa| grep -i mysql

rpm方式彻底卸载mysql

a）查看系统中是否以rpm包安装的mysql：

[root@localhost opt]# rpm -qa | grep -i mysql

MySQL-server-5.6.17-1.el6.i686

MySQL-client-5.6.17-1.el6.i686
b)卸载mysql

[root@localhost
local]# rpm -e MySQL-server-5.6.17-1.el6.i686

[root@localhost local]# rpm -e MySQL-client-5.6.17-1.el6.i686

c)删除mysql服务

[root@localhost
local]# chkconfig --list | grep -i mysql

[root@localhost local]# chkconfig --del mysql

d)删除分散mysql文件夹

[root@localhost local]# whereis mysql 或者 find
/ -name mysql

mysql:
/usr/share/mysql

清空相关mysql的所有目录以及文件
rm -rf /usr/share/mysql
