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-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.

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.]
