Linux安装Mysql

1：获取mysql YUM源进入mysql官网获取RPM包下载地址https://dev.mysql.com/downloads/repo/yum/(根据自身的Linux操作系统版本来下载对应的mysql版本)
右击 复制链接地址 https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
得到这个 这个就是Yum仓库的rpm包 其实就是一个下载地址
2：下载和安装mysql源先下载 mysql源安装包[root@localhost ~]# wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm-bash: wget: 未找到命令我们先安装下wget yum -y install wget然后执行 wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
安装mysql源yum -y localinstall mysql57-community-release-el7-11.noarch.rpm
3：在线安装Mysql
yum -y install mysql-community-server下载的东西比较多 要稍微等会；
4：启动Mysql服务systemctl start mysqld
5：设置开机启动
[root@localhost ~]# systemctl enable mysqld[root@localhost ~]# systemctl daemon-reload
6：修改root本地登录密码mysql安装完成之后，在/var/log/mysqld.log文件中给root生成了一个临时的默认密码。[root@localhost ~]# vi /var/log/mysqld.log


这里的临时密码 eMV.R#mWe3ha

[root@localhost ~]# mysql -u root -pEnter password: 输入临时密码 进入mysql命令行；mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Caofeng2012@';Query OK, 0 rows affected (0.00 sec)修改密码为 Caofeng2012@ (备注 mysql5.7默认密码策略要求密码必须是大小写字母数字特殊字母的组合，至少8位)
7：设置允许远程登录
Mysql默认不允许远程登录，我们需要设置下，并且防火墙开放3306端口；mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'Caofeng2012@' WITH GRANT OPTION;Query OK, 0 rows affected, 1 warning (0.01 sec)mysql> exit;Bye退出下；[root@localhost ~]# firewall-cmd --zone=public --add-port=3306/tcp --permanentsuccess[root@localhost ~]# firewall-cmd --reloadsuccess[root@localhost ~]# 开放3306端口
8：配置默认编码为utf8修改/etc/my.cnf配置文件，在[mysqld]下添加编码配置，如下所示：[mysqld]character_set_server=utf8init_connect='SET NAMES utf8'
[root@localhost ~]# vi /etc/my.cnf

编辑保存完 重启mysql服务；[root@localhost ~]# systemctl restart mysqld[root@localhost ~]# 查看下编码：mysql> show variables like '%character%';+--------------------------+----------------------------+| Variable_name | Value |+--------------------------+----------------------------+| character_set_client | utf8 || character_set_connection | utf8 || character_set_database | utf8 || character_set_filesystem | binary || character_set_results | utf8 || character_set_server | utf8 || character_set_system | utf8 || character_sets_dir | /usr/share/mysql/charsets/ |+--------------------------+----------------------------+8 rows in set (0.00 sec)
9：测试我们用本机的sqlyog远程连接下虚拟机里的mysql
