CentOS 7 mysql 5.7社区版下载 安装 配置_0neBean_NOTE

• 创建mysql清华镜像源:
  baseurl 决定了可以安装mysql 的版本,可以替换成需要安装的版本,具体的连接参考 清华yum源
  这里安装了centos7适用的5.7版本

cat > /etc/yum.repos.d/mysql-community.repo <

• 编译源

sudo yum makecache fast

• 安装mysql

yum -y install mysql-community-server

• 运行mysql

#启动
systemctl start mysqld
#查询
systemctl status mysqld
#停止
systemctl stop mysqld
#重启
systemctl restart mysqld
#自启动
systemctl enable mysqld
#关闭自启动
systemctl disable mysqld

mysql5.7 默认不支持很弱的密码 ,以下为了举例,将密码设置为'root',请不要这样做

• 获取mysql默认安装密码

awk '/temporary password/{print $NF}' /var/log/mysqld.log

• 重置root用户密码

ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';
flush privileges;

• 开启远程访问

grant all privileges on *.* to 'root'@'%' identified by 'root' with grant option;
flush privileges;

编辑配置文件:

vim /etc/my.cnf

添加如下参数:

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
character-set-server=utf8

重启:

systemctl restart mysqld
