- 註冊登入騰訊雲，下載putty連線。
- jdk安裝
輸入
小貼士：yum可以理解為一個聯網的軟體管家，詳見yum search jdk
這樣就會顯示出所有包括jdk的檔案Loaded plugins: fastestmirror, security Loading mirror speeds from cached hostfile =============================== N/S Matched: jdk =============================== copy-jdk-configs.noarch : JDKs configuration files copier java-1.6.0-openjdk.x86_64 : OpenJDK Runtime Environment java-1.6.0-openjdk-demo.x86_64 : OpenJDK Demos java-1.6.0-openjdk-devel.x86_64 : OpenJDK Development Environment java-1.6.0-openjdk-javadoc.x86_64 : OpenJDK API Documentation java-1.6.0-openjdk-src.x86_64 : OpenJDK Source Bundle java-1.7.0-openjdk.x86_64 : OpenJDK Runtime Environment java-1.7.0-openjdk-demo.x86_64 : OpenJDK Demos java-1.7.0-openjdk-devel.x86_64 : OpenJDK Development Environment java-1.7.0-openjdk-javadoc.noarch : OpenJDK API Documentation java-1.7.0-openjdk-src.x86_64 : OpenJDK Source Bundle java-1.8.0-openjdk-debug.x86_64 : OpenJDK Runtime Environment with full debug on java-1.8.0-openjdk-demo.x86_64 : OpenJDK Demos java-1.8.0-openjdk-demo-debug.x86_64 : OpenJDK Demos with full debug on java-1.8.0-openjdk-devel.x86_64 : OpenJDK Development Environment java-1.8.0-openjdk-devel-debug.x86_64 : OpenJDK Development Environment with : full debug on java-1.8.0-openjdk-headless.x86_64 : OpenJDK Runtime Environment java-1.8.0-openjdk-headless-debug.x86_64 : OpenJDK Runtime Environment with full : debug on java-1.8.0-openjdk-javadoc.noarch : OpenJDK API Documentation java-1.8.0-openjdk-javadoc-debug.noarch : OpenJDK API Documentation for packages : with debug on java-1.8.0-openjdk-src.x86_64 : OpenJDK Source Bundle java-1.8.0-openjdk-src-debug.x86_64 : OpenJDK Source Bundle for packages with : debug on ldapjdk-javadoc.x86_64 : Javadoc for ldapjdk icedtea-web.x86_64 : Additional Java components for OpenJDK - Java browser : plug-in and Web Start implementation ldapjdk.x86_64 : The Mozilla LDAP Java SDK Name and summary matches only, use "search all" for everything.
輸入
小貼士：-y意思是所有都選擇yesyum install-y java-1.8.0-openjdk*
這樣就會安裝所有jdk1.8相關的應用。
安裝完成之後
檢視jdk版本javac -version- 安裝mysql
大霧~~~之前的方法安裝的mysql是5.1的。。。。。現在說一下5.7的安裝方法
先去下載rpm檔案，傳到伺服器上，然後https://repo.mysql.com//mysql57-community-release-el6-11.noarch.rpmrpm -Uvh mysql57-community-release-el6-11.noarch.rpm
完成之後,啟動mysqlyum install -y mysql-community-server
首次登陸密碼在service mysqld start
搜一下password/var/log/mysqld.logA temporary password is generated for [email protected]: A<0Igo=wc8kkA<0Igo=wc8kk就是密碼
登陸mysql
再輸入密碼就能登陸mysql了，然後需要修改密碼，mysql -u root -p如果密碼設定太簡單出現以下的提示
如何解決
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements呢？ 這裡直接提供解決方案文末有詳細的說明必須修改兩個全域性引數：
首先，修改validate_password_policy引數的值mysql> set global validate_password_policy=0;再修改密碼的長度
set global validate_password_length=1;執行修改密碼就可以了
ALTER USER 'root'@'localhost' IDENTIFIED BY 'root123';（ALTER等可以寫成小寫）授權其他機器登陸
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'yourpassword' WITH GRANT OPTION;
附解除安裝mysql
同樣使用yum
mysql-devel 開發用到的庫以及包含檔案yum -y install mysql mysql-deve mysql-server
mysql mysql 客戶端
mysql-server 資料庫伺服器
安裝完成之後，啟動mysql
然後設定密碼service mysqld start
最後一步，允許別的計算機登陸mysql/usr/bin/mysqladmin -u root password'111111'
這樣你在本地就能用Navicat登陸mysql了GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'yourpassword' WITH GRANT OPTION;
