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、安装mysql
1、解压
# 将mysql-5.7.18-1.el6.x86_64.rpm-bundle.tar压缩包解压到/usr/wangzf/mysqlrpm/下 [[email protected] downloads]# tar -xvf mysql-5.7.18-1.el6.x86_64.rpm-bundle.tar -C ../mysqlrpm/ mysql-community-libs-compat-5.7.18-1.el6.x86_64.rpm mysql-community-test-5.7.18-1.el6.x86_64.rpm mysql-community-libs-5.7.18-1.el6.x86_64.rpm mysql-community-common-5.7.18-1.el6.x86_64.rpm mysql-community-embedded-5.7.18-1.el6.x86_64.rpm mysql-community-embedded-devel-5.7.18-1.el6.x86_64.rpm mysql-community-client-5.7.18-1.el6.x86_64.rpm mysql-community-devel-5.7.18-1.el6.x86_64.rpm mysql-community-server-5.7.18-1.el6.x86_64.rpm # 查看解压后的rpm软件包 [[email protected] downloads]# cd ../mysqlrpm/ [[email protected] mysqlrpm]# ll total 459488 -rw-r--r--. 1 7155 31415 23618836 Mar 20 05:40 mysql-community-client-5.7.18-1.el6.x86_64.rpm -rw-r--r--. 1 7155 31415 335496 Mar 20 05:40 mysql-community-common-5.7.18-1.el6.x86_64.rpm -rw-r--r--. 1 7155 31415 3747352 Mar 20 05:40 mysql-community-devel-5.7.18-1.el6.x86_64.rpm -rw-r--r--. 1 7155 31415 39086508 Mar 20 05:40 mysql-community-embedded-5.7.18-1.el6.x86_64.rpm -rw-r--r--. 1 7155 31415 135869292 Mar 20 05:40 mysql-community-embedded-devel-5.7.18-1.el6.x86_64.rpm -rw-r--r--. 1 7155 31415 2177064 Mar 20 05:40 mysql-community-libs-5.7.18-1.el6.x86_64.rpm -rw-r--r--. 1 7155 31415 1723180 Mar 20 05:40 mysql-community-libs-compat-5.7.18-1.el6.x86_64.rpm -rw-r--r--. 1 7155 31415 159060212 Mar 20 05:41 mysql-community-server-5.7.18-1.el6.x86_64.rpm -rw-r--r--. 1 7155 31415 104881084 Mar 20 05:41 mysql-community-test-5.7.18-1.el6.x86_64.rpm
2、安装mysql
# 想要安装mysqlclient和mysqlserver，需要先安装common和libs [[email protected] mysqlrpm]# rpm -ivh mysql-community-common-5.7.18-1.el6.x86_64.rpm Preparing... ########################################### [100%] 1:mysql-community-common ########################################### [100%] [[email protected] mysqlrpm]# rpm -ivh mysql-community-libs-5.7.18-1.el6.x86_64.rpm Preparing... ########################################### [100%] 1:mysql-community-libs ########################################### [100%] [[email protected] mysqlrpm]# rpm -ivh mysql-community-client-5.7.18-1.el6.x86_64.rpm Preparing... ########################################### [100%] 1:mysql-community-client ########################################### [100%] [[email protected] mysqlrpm]# rpm -ivh mysql-community-server-5.7.18-1.el6.x86_64.rpm Preparing... ########################################### [100%] 1:mysql-community-server ########################################### [100%] # 查看已安装的与mysql相关的软件 [[email protected] mysqlrpm]# rpm -qa|grep -i mysql mysql-community-common-5.7.18-1.el6.x86_64 mysql-community-client-5.7.18-1.el6.x86_64 mysql-community-libs-5.7.18-1.el6.x86_64 mysql-community-server-5.7.18-1.el6.x86_64
3、启动mysql
# 查看mysql服务的状态
[[email protected] 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）
[[email protected] mysqlrpm]# service mysqld start
Initializing MySQL database: [ OK ]
Installing validate password plugin: [ OK ]
Starting mysqld: [ OK ]
# 停止mysql服务
[[email protected] mysqlrpm]# service mysqld stop
Stopping mysqld: [ OK ]
# 启动mysql服务
[[email protected] mysqlrpm]# service mysqld start
Starting mysqld: [ OK ]
# 重启mysql服务
[[email protected] mysqlrpm]# service mysqld restart
Stopping mysqld: [ OK ]
Starting mysqld: [ OK ]
三、修改root密码
# 关闭mysql服务 [[email protected] ~]# service mysqld stop Stopping mysqld: [ OK ] # 安全模式下启动mysql，并且跳过权限表的验证 [[email protected]192 ~]# mysqld_safe --skip-grant-tables & [1] 1678 [[email protected]192 ~]# 2017-05-06T23:30:01.604144Z mysqld_safe Logging to ‘/var/log/mysqld.log‘. 2017-05-06T23:30:01.674987Z 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 Enter password: Welcome to the MySQL monitor.

Type ‘\c‘ to clear the current input statement. # 更改密码(这里设置的密码是1234) mysql> update mysql.user set authentication_string=password(‘1234‘) where user=‘root‘ and Host = ‘localhost‘; Query OK, 1 row affected, 1 warning (0.04 sec) Rows matched: 1 Changed: 1 Warnings: 1 # 刷新权限 mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) # 退出mysql mysql> quit Bye # 重启mysql [[email protected] ~]# service mysqld restart 2017-05-06T23:17:47.067045Z mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended Stopping mysqld: [ OK ] Starting mysqld: [ OK ] [2]- Done mysqld_safe --skip-grant-tables # 以root身份登陆 [[email protected] ~]# mysql -uroot -p # 输入刚才设置的密码1234，正常使用mysql Enter password: Welcome to the MySQL monitor.

Type ‘\c‘ to clear the current input statement. mysql>
四、远程访问mysql
1、centos开启防火墙端口3306
# 开放3306端口 [[email protected]192 ~]# /sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT # 保存 [[email protected]192 ~]# /etc/rc.d/init.d/iptables save iptables: Saving firewall rules to /etc/sysconfig/iptables:[ OK ] # 查看防火墙的状态 [[email protected]192 ~]# /etc/init.d/iptables status Table: filter Chain INPUT (policy ACCEPT) num target prot opt source destination 1 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:3306 2 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:3306 3 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:8080 4 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED 5 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 6 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 7 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22 8 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited Chain FORWARD (policy ACCEPT) num target prot opt source destination 1 REJECT all -- 0.0.0.0/0 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 [[email protected]192 ~]# iptables -D INPUT 2 # 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...） [[email protected]192 ~]# iptables -L -n --line-number Chain INPUT (policy ACCEPT) num target prot opt source destination 1 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:3306 2 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:8080 3 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED 4 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 5 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 6 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22 7 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited Chain FORWARD (policy ACCEPT) num target prot opt source destination 1 REJECT all -- 0.0.0.0/0 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 [[email protected]192 ~]# mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 8 Server version: 5.7.18 Copyright (c) 2000, 2017, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement. mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘1234‘ WITH GRANT OPTION; ERROR 1820 (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(‘1234‘); ERROR 1819 (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0，0/LOW、1/MEDIUM、2/STRONG。 mysql> set global validate_password_policy=0; Query OK, 0 rows affected (0.00 sec) # 设置密码长度:8-->4 mysql> select @@validate_password_length; +----------------------------+ | @@validate_password_length | +----------------------------+ | 8 | +----------------------------+ 1 row in set (0.00 sec) mysql> set global validate_password_length=4; Query OK, 0 rows affected (0.00 sec) mysql> select @@validate_password_length; +----------------------------+ | @@validate_password_length | +----------------------------+ | 4 | +----------------------------+ 1 row in set (0.00 sec) # 设置密码为1234 mysql> SET PASSWORD = PASSWORD(‘1234‘); Query OK, 0 rows affected, 1 warning (0.00 sec) # 设置允许远程访问 mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘1234‘ WITH GRANT OPTION; Query OK, 0 rows affected, 1 warning (0.00 sec) # 刷新权限 mysql> flush privileges; Query OK, 0 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 6.1.7601] 版权所有 (c) 2009 Microsoft Corporation。保留所有权利。 C:\Users\Administrator>mysql -h 192.168.22.130 -u root -p Enter password: **** Welcome to the MySQL monitor.
