• 配置java

  • yum -y list java* //列出所有的java源
  • yum -y install java-1.8.0-openjdk* //安装Java 1.8，稍等片刻安装即可安成。
  • 默认安装的JDK目录为： /usr/lib/jvm/java-1.8.0-openjdk
  • 如需配置环境变量,以root身份编辑etc/profile,具体如下：
  • vim etc/profile
  • export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.111-2.b15.el7_3.x86_64
  • export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
  • export PATH=$PATH:$JAVA_HOME/bin
  • source /etc/profile #立即生效果
  • echo $JAVA_HOME #查看效果

• 配置tomcat

  • 下载tomcat
  • cd /java/
  • wget http://mirrors.hust.edu.cn/apache/tomcat/tomcat-8/v8.0.44/bin/apache-tomcat-8.0.44-deployer.tar.gz 
    //下载tomcat
  • tar -zxv -f apache-tomcat-8.0.44-deployer.tar.gz //解压
  • mv apache-tomcat-8.0.44 tomcat //重命名
  • 配置路径：CATALINA_HOME=/java/tomcat/
  • 设置自启动：转自http://blog.youkuaiyun.com/guoxingege/article/details/48968797 
    
    • 修改Tomcat目录下面的/bin/startup.sh文件； 
      
export JAVA_HOME=/usr/local/JDK7 
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:. 
export PATH=$PATH:$JAVA_HOME/bin 
export CATALINA_HOME=/usr/local/tomcat7_1 

    • 然后运行： /usr/local/tomcat7_1/bin/catalina.sh start
    • 在/etc/rc.d/rc.local中加入: /usr/local/tomcat7_1/bin/startup.sh
• 配置mysql 
  
  • wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm //下载mysql5.6
  • rpm -ivh mysql-community-release-el7-5.noarch.rpm
  • yum install mysql-community-server //用yum安装
  • service mysqld start //开启mysql
  • mysql -uroot //最后修改密码 
    
    • mysql> set password for 'root'@'localhost' = password('mypasswd');
    • mysql> exit

如需允许远程连接，执行：GRANT ALL PRIVILEGES ON . TO ‘root’@’%’ IDENTIFIED BY ‘youpassword’ WITH GRANT OPTION;
