rpm安装mysql

rpm安装mysql
需要下载mysql的四个rpm包：
   mysql-community-client-5.7.18-1.el6.x86_64.rpm
   mysql-community-common-5.7.18-1.el6.x86_64.rpm
   mysql-community-libs-5.7.18-1.el6.x86_64.rpm
   mysql-community-server-5.7.18-1.el6.x86_64.rpm

1、rpm -qa | grep -i mysql
2、将上一步找到的mysql相关的包都删除
   rpm -e --nodeps mysql-libs* //*号指代实际包名，请实际情况输入完整包名
   rpm -e mysql-server*（如果有）
   rpm -e mysql-client*（如果有）
3、检查并删除老版本mysql的开发头文件和库
   命令：
   rm -fr /usr/lib/mysql
rm -fr /usr/include/mysql
注意：卸载后/var/lib/mysql中的数据及/etc/my.cnf不会删除，如果确定没用后就手工删除
rm -f /etc/my.cnf
rm -fr /var/lib/mysql
rm -fr /usr/share/mysql
4、安装perl
   yum install perl -y
5、下载numactl-2.0.9-2.el6.x86_64.rpm并安装
   rpm -ivh numactl-2.0.9-2.el6.x86_64.rpm
6、安装mysql（有顺序要求）
   rpm -ivh mysql-community-common-5.7.18-1.el6.x86_64.rpm
   rpm -ivh mysql-community-libs-5.7.19-1.el6.x86_64.rpm
   rpm -ivh mysql-community-client-5.7.19-1.el6.x86_64.rpm
   rpm -ivh mysql-community-server-5.7.19-1.el6.x86_64.rpm
7、#修改配置文件位置
[root@localhost rpm]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf(如果/etc/my.cnf已经存在，则无需操作)

   如果需要更改默认的data文件夹，请提前更改my.cnf中datadir目录，
   socket和pid-file建议还是使用默认的目录/var/lib/mysql
8、修改/etc/my.cnf文件，设置数据库的编码方式：
   [client]
   default-character-set=utf8
   [mysql]
   default-character-set=utf8
   [mysqld]
   character_set_server=utf8
9、如果出现错误，请查看/etc/my.cnf文件中指定的错误log日志的文件
10、service mysqld start
11、找到随机密码：
   在/var/log/mysqld.log中有一行：
       A temporary password is generated for root@localhost，后面就是随机密码
   # mysql -uroot -p"yAe7QGVJ;HlR"使用随机密码登录系统
12、修改默认密码：
   set global validate_password_policy=0;
   set global validate_password_length=6;
   set password for 'root'@'localhost'=password('123456');
   搞定
13、设置密码以及查看编码方式
   mysql> set global validate_password_policy=0;
   Query OK, 0 rows affected (0.00 sec)

mysql> set global validate_password_length=6;
Query OK, 0 rows affected (0.00 sec)

mysql> set password for 'root'@'localhost'=password('123456');
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql>
14、给root设置远程登录权限
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
15、chkconfig mysqld on 设置开机启动
至此，mysql-5.7安装完毕！
