# 3.将下载的安装包放到上传到/usr/local/mysql文件夹下（自己新建准备），解压缩

[root@vm-xiluhua][/usr/local/mysql]$ tar -xvf mysql-5.7.15-1.el7.x86_64.rpm-bundle.tar

# 3.1.目录结构如下，实际用到的安装包仅为红色部分

# 4.安装（需要使用root账户操作，不然没有权限）
    　4.1.注意事项：必须依次安装，因为他们之间存在依赖链
    　4.2.注意事项：尝试使用rpm工具的--prefix或--relocate指定安装目录，系统反馈不允许

# 5.经过以上步骤，安装基本完成，但还需要配置mysql的初始化文件/etc/my.cnf

[root@vm-xiluhua][/usr/local/mysql]$ cd /etc/
    [root@vm-xiluhua][/etc]$ less my.cnf

# 6.在my.cnf的[mysqld]代码下方添加skip-grant-tables

[root@vm-xiluhua][/etc]$ vi my.cnf
    　# For advice on how to change settings please see
    　# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
    
    　[mysqld]
    　skip-grant-tables

# 7.启动mysql

[root@vm-xiluhua][/etc]$ service mysqld start
    Redirecting to /bin/systemctl start  mysqld.service

# 8.验证mysql是否启动

[root@vm-xiluhua][/etc]$ netstat -apln | grep mysql
    tcp6       0      0 :::3306                 :::*                    LISTEN      3625/mysqld         
    unix  2      [ ACC ]     STREAM     LISTENING     92437    3625/mysqld          /var/lib/mysql/mysql.sock

# 9.首次登录（第6步[mysqld]代码下方添加skip-grant-tables，目的是为了首次登录时不用输入密码）

![复制代码][copycode.gif]

[root@vm-xiluhua][/etc]$ mysql

# 10.显示以上，恭喜！安装完成

这时，在windows下使用Navicat以root账户连接mysql可以密码为空。
    如telnet 3306端口不通，连接不上mysql，请关闭linux服务器防火墙。

# 11.安装后续工作，设置root密码

![复制代码][copycode.gif]

mysql> update user set authentication_string = password('111111'),host='%' where user = 'root';
    Query OK, 1 row affected, 1 warning (0.00 sec)
    Rows matched: 1  Changed: 1  Warnings: 1

    Redirecting to /bin/systemctl restart  mysqld.service
    
    [root@vm-xiluhua][/usr/local/mysql]$ mysql -u root -p

    mysql> 
    这时，在windows下使用Navicat以root账户连接mysql需要使用密码“111111”。

至此，完成rpm包安装mysql

卸载
    # 1.关闭MySQL服务

[root@vm-xiluhua][/etc]$ service mysqld stop
    Redirecting to /bin/systemctl stop  mysqld.service

# 2.卸载MySQL软件包

![复制代码][copycode.gif]

# 2.1.查询系统下的所有mysql软件包
    [root@vm-xiluhua][/etc]$ rpm -aq | grep mysql

    mysql-community-client-5.7.15-1.el7.x86_64
    
    # 2.2.卸载系统下的所有mysql软件包
    [root@vm-xiluhua][/etc]$ rpm -ev mysql-community-server-5.7.15-1.el7.x86_64

# 3.删除MySQL安装文件夹

![复制代码][copycode.gif]

# 再次查看剩下有哪些文件夹
    [root@vm-xiluhua][/etc]$ find / -name "mysql"
    /var/lib/mysql
    /var/lib/mysql/mysql

    # 删除
    [root@vm-xiluhua][/etc]$ rm -rf /var/lib/mysql
    # 删除
    [root@vm-xiluhua][/etc]$ rm -rf /usr/share/mysql;
    
    # 再次查看还剩下有哪些
    [root@vm-xiluhua][/etc]$ find / -name "mysql"
    /usr/lib/python2.7/site-packages/clufter/filters/cluster/rm/mysql　　# 非直属包下的，就留着
    /usr/lib/ocf/resource.d/heartbeat/mysql　　　　　　 # 非直属包下的，就留着
    /usr/lib64/perl5/vendor_perl/auto/DBD/mysql　　　　# 非直属包下的，就留着
