centos下安裝JAVA開發工具(3)------Mysql

安裝MySQL

1. 上傳MySQL-server-5.5.48-1.linux2.6.x8664.rpm到Linux上

2. 解壓ta包 獲得一大堆rpm文件
   tar -xvf MySQL-5.6.25-1.el6.x86_64.rpm-bundle.tar

   MySQL-client-5.6.25-1.el6.x86_64.rpm
     MySQL-devel-5.6.25-1.el6.x86_64.rpm
     MySQL-embedded-5.6.25-1.el6.x86_64.rpm
     MySQL-server-5.6.25-1.el6.x86_64.rpm
     MySQL-shared-5.6.25-1.el6.x86_64.rpm
     MySQL-shared-compat-5.6.25-1.el6.x86_64.rpm
     MySQL-test-5.6.25-1.el6.x86_64.rpm

3. rpm安裝mysql-server
   rpm -ivh MySQL-server-5.6.25-1.el6.x86_64.rpm

4. 出現錯誤
   file /usr/share/mysql/charsets/cp1256.xml from install of MySQL-server-5.6.25-1.el6.x86_64 conflicts with file from package mariadb-libs-1:5.5.56-2.el7.x86_64

5. 卸載 mariadb-libs-1:5.5.56-2.el7.x86_64 解決依賴
   rpm -e --nodeps mariadb-libs-1:5.5.56-2.el7.x86_64
6. 再次執行第三步 安裝server
7. 安裝客戶端
   rpm -ivhMySQL-client-5.6.25-1.el6.x86_64.rpm
8. 啓動mysql
   service mysql start
9. 初始化mysql
   /usr/bin/mysql_secure_installation
10. 測試mysql
    mysql -u root -p

注意事項

初始化mysql時可能出現問題

• 先關閉mysql
  service mysql stop
• 跳過檢查
  service mysql start --skip-grant-tables

• 進入mysql 設置密碼

  mysql> update mysql.user set password=PASSWORD('newpassword') where User='root'; 
  mysql> flush privileges; 
  mysql> quit

• 重啓mysql
  service mysql start
• 鏈接
  mysql -u root -p

備註

• 修改mysql密碼
  set password for root@localhost = password('123');
