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-5.7.18-1.el6.x86_64.rpm-bundle.tar压缩包解压到/usr/wangzf/mysqlrpm/下 [root@localhost 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 [root@localhost downloads]# cd ../mysqlrpm/ [root@localhost 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 [root@localhost mysqlrpm]# rpm -ivh mysql-community-common-5.7.18-1.el6.x86_64.rpm Preparing... ########################################### [100%] 1:mysql-community-common ########################################### [100%] [root@localhost mysqlrpm]# rpm -ivh mysql-community-libs-5.7.18-1.el6.x86_64.rpm Preparing... ########################################### [100%] 1:mysql-community-libs ########################################### [100%] [root@localhost mysqlrpm]# rpm -ivh mysql-community-client-5.7.18-1.el6.x86_64.rpm Preparing... ########################################### [100%] 1:mysql-community-client ########################################### [100%] [root@localhost 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 [root@localhost 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
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-5.7.18-1.el6.x86_64.rpm warning: mysql-community-server-5.7.18-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY error: Failed dependencies: /usr/bin/perl is needed by mysql-community-server-5.7.18-1.el6.x86_64 libnuma.so.1()(64bit) is needed by mysql-community-server-5.7.18-1.el6.x86_64 libnuma.so.1(libnuma_1.1)(64bit) is needed by mysql-community-server-5.7.18-1.el6.x86_64 libnuma.so.1(libnuma_1.2)(64bit) is needed by mysql-community-server-5.7.18-1.el6.x86_64 perl(File::Path) is needed by mysql-community-server-5.7.18-1.el6.x86_64 perl(Getopt::Long) is needed by mysql-community-server-5.7.18-1.el6.x86_64 perl(POSIX) is needed by mysql-community-server-5.7.18-1.el6.x86_64 perl(strict) is needed by mysql-community-server-5.7.18-1.el6.x86_64 [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@192 ~]# mysqld_safe --skip-grant-tables & [1] 1678 [root@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.

五、远程访问mysql
1、centos开启防火墙端口3306
# 开放3306端口 [root@192 ~]# /sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT # 保存 [root@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 [root@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 [root@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...） [root@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 [root@192 ~]# mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or g.

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
