yum安装mysql:
1. 查看有没有安装过 ? ? yum list installed MySQL* （有存在要卸载yum remove MySQL*） ? ? rpm -qa | grep mysql* ? ? 查看有没有安装包： ? ? yum list mysql* ? 2. 安装mysql客户端 ? ? yum -y install mysql ? ? 安装mysql 服务器端 ? ? yum?-y?install mysql-server ?mysql-devel ? 3. 启动&&停止 数据库字符集设置 ? ? mysql配置文件/etc/my.cnf中加入default-character-set=utf8 ? ? 启动mysql服务： service mysqld start或者/etc/init.d/mysqld start ? ? 开机启动： ? ? ? ? 添加开机启动：chkconfig --add mysqld; ? ? ? ? 开机启动：chkconfig mysqld on; ? ? ? ? 查看开机启动设置是否成功chkconfig --list | grep mysql* mysqld 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭停止：?? ? ? 停止 ? ? ? ? service mysqld stop ? ?如果需要外网可以访问需要再做如下设置
? ? ? ? 授权用户可以从远程登陆 ? ? ? ? grant all PRIVILEGES on *.* to root@'%' ?identified by '123456'; ? ? ? ? flush privileges ; ? ? 5. 远程访问 开放防火墙的端口号mysql ? ? 增加权限：mysql库中的user表新增一条记录Host为“%”，User为“root”。 ? ? 一般开发测试直接把防火墙关闭| 1 2 3 4 5 6 |
su root
service?iptables?stop?#关闭防火墙
service?iptables?status?#验证是否关闭
chkconfig?iptables?off?#关闭防火墙的开机自动运行
chkconfig?–list?|?grep iptables?#验证防火墙的开机自动运行
vim?/etc/sysconfig/selinux #?禁用selinux，将SELINUX=disabled

yum安装MySQL指定版本
? 默认yum只能安装mysql 5.1，我们可以自己配置通过yum安装5.6或者其他版本。 ? 1. 查看系统里面有没有mysql 的repo（可以参考上面第一步卸载） yum repolist all | grep mysql ? 2. 如果没有发现，则需要配置repo 只能有一个是 enabled=1的，其他的都得enabled=0。 vim /etc/yum.repos.d/mysql-community.repo 输入如下内容[mysql-connectors-community]3. 再看看是否存在mysql的repo yum repolist enabled | grep mysql 可以看到已经有了 ? 4. 签名 vim /etc/pki/rpm-gpg/RPM-GPG-KEY-mysql 写入如下内容
name=MySQL Connectors Community
baseurl=http://repo.mysql.com/yum/mysql-connectors-community/el/6/$basearch/
