1.linux系统 mysql安装
1.1.使用yum list | grep mysql 来查找yum源中是否有mysql
[root@VM_47_56_centos ~]# yum list | grep mysql
akonadi-mysql.x 86_64 1.9 .2 -4. el7 base
apr-util-mysql.x 86_64 1.5 .2 -6. el7 base
mysql-proxy.x 86_64 0.8 .5 -2. el7 epel
mysql-proxy-devel.x 86_64 0.8 .5 -2. el7 epel
mysql-router.x 86_64 2.0 .2 -1. el7 mysql-tools-community
mysql-router-debuginfo.x 86_64 2.0 .2 -1. el7 mysql-tools-community
mysql-utilities.noarch 1.5 .6 -1. el7 mysql-tools-community
mysql-utilities-extra.noarch 1.5 .6 -1. el7 mysql-tools
mysqlreport.noarch 3.5 -11. el7 epel
mysqltuner.noarch 1.2 .0 -7. el7 epel
省略部分内容。。。。
[root@VM_47_56_centos ~]# 1.2.下载mysql的repo源
$ wget http:$ sudo rpm -ivh mysql-community-release-el7-5. noarch.rpm
安装这个包后，会获得两个mysql的yum repo源：
/etc/yum.repos.d/mysql-community.repo和
/etc/yum.repos.d/mysql-community-source.repo。1.4.安装mysql
$ sudo yum install mysql-server[root@izwz 91h49n3mj8r232gqwez opt]# sudo yum install mysql-server

下边的安装和其他安装一样，
根据步骤安装就可以了，不过安装完成后，没有密码，需要重置密码。1.5.重置密码
1.5.1.登录
$ mysql -u root
登录时有可能报这样的错：
ERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock‘ (2 )，
原因是/var/lib/mysql的访问权限问题。下面的命令把/var/lib/mysql的拥有者改为当前用户：
$ sudo chown -R mysql:mysql /var/lib/mysql #这里的mysql是用户名（需要设置用户组合用户）
然后重启
$ service mysqld restart1.5.2.接下来登录重置密码：
$ mysql -u root
mysql > use mysql;
mysql > update user set password=password('xu827928' ) where user='root' ;
mysql > exit;1.6.开放3306端口(可以不用设置)
sudo systemctl stop firewalld.service
iptables -I INPUT -p tcp --dport 3306 -j ACCEPT
这样从其它客户机也可以连接上mysql服务了。1.7.修改权限可以使其他机器登录：
[root@izwz 91h49n3mj8r232gqwez ~]# mysql -h localhost -u root
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root' @'%' WITH GRANT OPTION
mysql>FLUSH PRIVILEGES
mysql>EXIT
