linux簡單配置mysql數據庫

下載命令

複製到命令行下載

wget http://mirrors.ustc.edu.cn/mysql-ftp/Downloads/MySQL-5.7/mysql-community-server-5.7.25-1.el7.x86_64.rpm
wget http://mirrors.ustc.edu.cn/mysql-ftp/Downloads/MySQL-5.7/mysql-community-client-5.7.25-1.el7.x86_64.rpm
wget http://mirrors.ustc.edu.cn/mysql-ftp/Downloads/MySQL-5.7/mysql-community-common-5.7.25-1.el7.x86_64.rpm
wget http://mirrors.ustc.edu.cn/mysql-ftp/Downloads/MySQL-5.7/mysql-community-libs-5.7.25-1.el7.x86_64.rpm

安裝相關軟件

yum  install  -y   net-tools.x86_64  libaio.x86_64   perl.x86_64

---

安裝mysql服務器

如果有mariadb，請卸載避免衝突

yum remove -y mariadb-libs.x86_64

沒有mariadb，就直接安裝

yum install -y mysql-community*

---

啓動服務器

systemctl start mysqld    //啓動
systemctl enable mysqld   //設置開機自啓
systemctl status mysqld   //查詢mysql狀態

---

查詢mysql初始密碼

cat /var/log/mysqld.log  | grep 'password'

冒號後除空格外，全是密碼。

---

登錄mysql

密碼直接複製

mysql -uroot -p'edkfT4U=7d#;'

登錄成功

---

修改密碼

mysqladmin -uroot  -p'es,W;ya(K1Th'  password  '你想修改的密碼'
