vm12下Centos6安装mysql5.7

一、下载mysql的rpm tar文件

文件名称：mysql-5.7.18-1.el6.x86_64.rpm-bundle.tar
官方地址：https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.18-1.el6.x86_64.rpm-bundle.tar

二、卸载原有的mysql

请查看tony~tian的博客：https://yq.aliyun.com/articles/58287

三、安装mysql

1、解压

# 将mysql-5.7.-.el6.x86_64.rpm-bundle.tar压缩包解压到/usr/wangzf/mysqlrpm/下
[root@localhost downloads]# tar -xvf mysql-5.7.-.el6.x86_64.rpm-bundle.tar -C ../mysqlrpm/
mysql-community-libs-compat-5.7.-.el6.x86_64.rpm
mysql-community-test-5.7.-.el6.x86_64.rpm
mysql-community-libs-5.7.-.el6.x86_64.rpm
mysql-community-common-5.7.-.el6.x86_64.rpm
mysql-community-embedded-5.7.-.el6.x86_64.rpm
mysql-community-embedded-devel-5.7.-.el6.x86_64.rpm
mysql-community-client-5.7.-.el6.x86_64.rpm
mysql-community-devel-5.7.-.el6.x86_64.rpm
mysql-community-server-5.7.-.el6.x86_64.rpm

# 查看解压后的rpm软件包
[root@localhost downloads]# cd ../mysqlrpm/
[root@localhost mysqlrpm]# ll
total

-rw-r--r--.       Mar  : mysql-community-libs-compat-5.7.-.el6.x86_64.rpm
-rw-r--r--.     Mar  : mysql-community-server-5.7.-.el6.x86_64.rpm
-rw-r--r--.     Mar  : mysql-community-test-5.7.-.el6.x86_64.rpm

2、安装mysql

# 想要安装mysqlclient和mysqlserver，需要先安装common和libs
[root@localhost mysqlrpm]# rpm -ivh mysql-community-common-5.7.-.el6.x86_64.rpm
Preparing...                ########################################### [%]
   :mysql-community-common ########################################### [%]
[root@localhost mysqlrpm]# rpm -ivh mysql-community-libs-5.7.-.el6.x86_64.rpm
Preparing...                ########################################### [%]
   :mysql-community-libs   ########################################### [%]
[root@localhost mysqlrpm]# rpm -ivh mysql-community-client-5.7.-.el6.x86_64.rpm
Preparing...                ########################################### [%]
   :mysql-community-client ########################################### [%]
[root@localhost mysqlrpm]# rpm -ivh mysql-community-server-5.7.-.el6.x86_64.rpm
Preparing...                ########################################### [%]
   :mysql-community-server ########################################### [%]

# 查看已安装的与mysql相关的软件
[root@localhost mysqlrpm]# rpm -qa|grep -i  mysql
mysql-community-common-5.7.-.el6.x86_64
mysql-community-client-5.7.-.el6.x86_64
mysql-community-libs-5.7.-.el6.x86_64
mysql-community-server-5.7.-.el6.x86_64

安装异常处理：

# 如果出现以下错误，请先安装perl、libnuma
[root@slave01 mysqlrpm]# rpm -ivh mysql-community-server-5.7.-.el6.x86_64.rpm
warning: mysql-community-server-5.7.-.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

 [root@slave01 mysqlrpm]# yum install perl
 [root@slave01 mysqlrpm]# yum install libnuma*

3、启动mysql

# 查看mysql服务的状态
[root@localhost mysqlrpm]# service mysqld status
mysqld is stopped

# mysql尚未启动，使用service mysqld start启动（这里是第一次启动，会初始化一些参数）
[root@localhost mysqlrpm]# service mysqld start
Initializing MySQL database:                               [  OK  ]
Installing validate password plugin:                       [  OK  ]
Starting mysqld:                                           [  OK  ]

# 停止mysql服务
[root@localhost mysqlrpm]# service mysqld stop
Stopping mysqld:                                           [  OK  ]

# 启动mysql服务
[root@localhost mysqlrpm]# service mysqld start
Starting mysqld:                                           [  OK  ]

# 重启mysql服务
[root@localhost mysqlrpm]# service mysqld restart
Stopping mysqld:                                           [  OK  ]
Starting mysqld:                                           [  OK  ]

四、修改root密码

# 关闭mysql服务
[root@localhost ~]# service mysqld stop
Stopping mysqld:                                           [  OK  ]

# 安全模式下启动mysql，并且跳过权限表的验证
[root@ ~]# mysqld_safe --skip-grant-tables &
[]
[root@ ~]# --06T23::.604144Z mysqld_safe Logging to '/var/log/mysqld.log'.
--06T23::.674987Z mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql

# 准备登陆
mysql -u root -p

# 这里随便输入密码，都可以进入mysql

五、远程访问mysql

1、centos开启防火墙端口3306

# 开放3306端口
[root@ ~]# /sbin/iptables -I INPUT -p tcp --dport  -j ACCEPT

# 保存
[root@ ~]# /etc/rc.d/init.d/iptables save
iptables: Saving firewall rules to /etc/sysconfig/iptables:[  OK  ]

# 查看防火墙的状态
[root@ ~]# /etc/init.d/iptables status
Table: filter
Chain INPUT (policy ACCEPT)
num  target     prot opt source               destination
    ACCEPT     tcp  --  0.0.0.0/            0.0.0.0/           tcp dpt:

    ACCEPT     icmp --  0.0.0.0/            0.0.0.0/
    ACCEPT     all  --  0.0.0.0/            0.0.0.0/
    ACCEPT     tcp  --  0.0.0.0/            0.0.0.0/           state NEW tcp dpt:
    REJECT     all  --  0.0.0.0/            0.0.0.0/           reject-with icmp-host-prohibited 

Chain FORWARD (policy ACCEPT)
num  target     prot opt source               destination
    REJECT     all  --  0.0.0.0/            0.0.0.0/           reject-with icmp-host-prohibited 

Chain OUTPUT (policy ACCEPT)
num  target     prot opt source               destination         

# 删除刚刚添加的端口
# 这里我原先已经开放了3306端口，再次添加又增加了一个3306，所以显示2个3306，这里我将num为2的那个3306删除
[root@ ~]# iptables -D INPUT 

# 查看防火墙的状态（奇怪的是我原本也开放的有80端口，莫名其妙没了...）
[root@ ~]# iptables -L -n --line-number
Chain INPUT (policy ACCEPT)
num  target     prot opt source               destination
    ACCEPT     tcp  --  0.0.0.0/            0.0.0.0/           tcp dpt:
    ACCEPT     tcp  --  0.0.0.0/            0.0.0.0/           tcp dpt:
    ACCEPT     all  --  0.0.0.0/            0.0.0.0/           state RELATED,ESTABLISHED
    ACCEPT     icmp --  0.0.0.0/            0.0.0.0/
    ACCEPT     all  --  0.0.0.0/            0.0.0.0/
    ACCEPT     tcp  --  0.0.0.0/            0.0.0.0/           state NEW tcp dpt:
    REJECT     all  --  0.0.0.0/            0.0.0.0/           reject-with icmp-host-prohibited 

Chain FORWARD (policy ACCEPT)
num  target     prot opt source               destination
    REJECT     all  --  0.0.0.0/            0.0.0.0/           reject-with icmp-host-prohibited 

Chain OUTPUT (policy ACCEPT)
num  target     prot opt source               destination         

2、修改mysql表，允许远程访问

# 登陆
[root@ ~]# mysql -uroot -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is
Server version: 5.7.

Copyright (c) , , Oracle and/or its affiliates. All rights reserved.

Oracle is a registered trademark of Oracle Corporation and/or its

owners.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '' WITH GRANT OPTION;
ERROR  (HY000): You must reset your password using ALTER USER statement before executing this statement.

# 在设置远程登录原先是提示错误。百度一番，需要设置root密码，好吧，我原先是1234，现在还设置为1234
mysql> SET PASSWORD = PASSWORD('');
ERROR  (HY000): Your password does not satisfy the current policy requirements

# 发现是密码太脆弱，究其根本是由于mysql有密码验证的策略，那么这里设置一下
# 设置密码强度检查等级为0，/LOW、/MEDIUM、/STRONG。
mysql> set global validate_password_policy=;
Query OK,  rows affected (0.00 sec)

# 设置密码长度:-->
mysql> select @@validate_password_length;
+----------------------------+
| @@validate_password_length |
+----------------------------+
|                           |
+----------------------------+
 row in set (0.00 sec)

mysql> set global validate_password_length=;
Query OK,  rows affected (0.00 sec)

mysql> select @@validate_password_length;
+----------------------------+
| @@validate_password_length |
+----------------------------+
|                           |
+----------------------------+
 row in set (0.00 sec)

# 设置密码为1234
mysql> SET PASSWORD = PASSWORD('');
Query OK,  rows affected,  warning (0.00 sec)

# 设置允许远程访问
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '' WITH GRANT OPTION;
Query OK,  rows affected,  warning (0.00 sec)

# 刷新权限
mysql> flush privileges;
Query OK,  rows affected (0.00 sec)
# 退出
mysql> exit;
Bye

3、windows下远程连接vm12下centos6.9的mysql

Microsoft Windows [版本 6.1.]

C:\Users\Administrator>mysql -h 192.168.22.130 -u root -p

最后就问下：惊不惊喜？意不意外？
