Linux(CentOS6.5)中安装mysql
1.上传相关包(*.tar.gz等)
使用相关软件上传或用Xshell连接后下载命令:yum install lrzsz
2.安装mysql5.7
1)查看本地是否安装了mysql:rpm -qa | grep mysql
2)卸载本地自带的mysql:yum remove mysql包
3)官网yum repository 下载安装包:wget http://dev.mysql.com/get/mysql80-community-release-el6-3.noarch.rpm
或手动下载并上传至linux
然后选择
我这里用的是CentOS6.5,所有下载这个
4)安装下载下来的rpm包
yum localinstall mysql80-community-release-el6-3.noarch.rpm
5)查看可用的安装包
yum repolist enabled|grep mysql
6)接下来需要更改mysql版本了
vim /etc/yum.repos.d/mysql-community.repo
比如要安装5.7版本,将80源的enabled=1改成enabled=0。然后再将5.7源的enabled=0改成enabled=1即可。
7)安装mysql
yum install mysql-community-server -y
8)启动mysql并更改相关配置
1>启动mysql:service mysqld start
2>查看mysql是否自启动,并且设置开启自启动
chkconfig --list | grep mysqld
chkconfig mysqld on
3>查看初始密码:grep "password" /var/log/mysqld.log
4>登录mysql:mysql -u root -p
5>修改密码:SET PASSWORD FOR 'root'@'localhost' = PASSWORD('123456');
修改的密码过于简单可能会报错:
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
执行以下语句:
set global validate_password_policy=0;
set global validate_password_length=4;
再执行修改密码语句
6>开放root账户远程访问
grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;
7>刷新权限表
FLUSH PRIVILEGES;
8>修改字符集为UTF-8
linux中:vim /etc/my.cnf
在[mysqld]部分添加:
port=3306
character-set-server=utf8
在文件末尾新增[client]段,并在[client]段添加:
port=3306
socket=/var/lib/mysql/mysql.sock
default-character-set=utf8
在[mysql]部分添加:
no-auto-rehash
default-character-set=utf8
修改好之后重启mysqld服务:
service mysqld restart
(导入sql脚本,先use 数据库,再source /home/sql/test.sql)
9>用软件测试远程连接mysql
