本文为大家介绍了CentOS 7 64位 安装 MySQL5.7 的详细步骤
1、配置YUM源
在[MySQL]官网中下载YUM源rpm安装包:http://dev.mysql.com/downloads/repo/yum/
# 下载mysql源安装包
shell> wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
#安装mysql源
shell> yum localinstall mysql57-community-release-el7-8.noarch.rpm
检查mysql源是否安装成功
shell> yum repolist enabled | grep "mysql.*-community.*"
2、安装MySQL
shell> yum install mysql-community-server
3、配置默认编码为utf8 并且设置不区分大小写
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=utf8
init_connect='SET NAMES utf8'
lower_case_table_names=1
4、启动MySQL服务
shell> systemctl start mysqld
5、开机启动
shell> systemctl enable mysqld
shell> systemctl daemon-reload
6、修改root默认密码
mysql安装完成之后,在/var/log/mysqld.log文件中给root生成了一个默认密码。通过下面的方式找到root默认密码,然后登录mysql进行修改:
shell> grep 'temporary password' /var/log/mysqld.log
查看到密码后用root登录修改密码
shell> mysql -uroot -p
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';
或者
mysql> set password for 'root'@'localhost'=password('MyNewPass4!');
注意:mysql5.7默认安装了密码安全检查插件(validate_password),默认密码检查策略要求密码必须包含:大小写字母、数字和特殊符号,并且长度不能少于8位。否则会提示ERROR 1819 (HY000): Your password does not satisfy the current policy requirements错误
7、创建数据库并添加远程登录用户
默认只允许root帐户在本地登录,如果要在其它机器上连接mysql,必须修改root允许远程连接,或者添加一个允许远程连接的帐户,为了安全起见,我添加一个新的帐户:
mysql> create database yamidb CHARACTER SET utf8 COLLATE utf8_general_ci;
mysql> GRANT ALL PRIVILEGES ON yamidb.* TO 'yami'@'%' IDENTIFIED BY 'Yami@2019';
