一、安装 vjudge
手动执行以下shell命令：
#!/bin/bash
apt-get update
apt-get -y install tomcat8 mysql-server
wget https://github.com/zhblue/vjudge/raw/master/vjudge.war
cp vjudge.war /var/lib/tomcat8/webapps/
## 等待tomcat自动解压缩得到vjudge目录
echo "waiting for tomcat8 deploying vjudge.war ... 8s count down"
sleep 8
## 缓存各种数据
DBUSER=`cat /etc/mysql/debian.cnf | grep user|awk ‘{print $3}‘|head -1`
DBPASS=`cat /etc/mysql/debian.cnf | grep password|awk ‘{print $3}‘|head -1`
SQL=`find /var/lib/tomcat8/webapps/vjudge -name "*.sql"`
cat $SQL | mysql -u$DBUSER -p$DBPASS #导入数据库
cd /var/lib/tomcat8/webapps/vjudge/WEB-INF/classes
## 将缓存的数据写入配置文件
sed -i "s/jdbc.username=root/jdbc.username=$DBUSER/g" config.properties
sed -i "s/jdbc.password=root/jdbc.password=$DBPASS/g" config.properties
sed -i "s:remote_accounts.json:/var/lib/tomcat8/webapps/vjudge/WEB-INF/classes/remote_accounts.json:g" config.properties
sed -i "s:http_client.json:/var/lib/tomcat8/webapps/vjudge/WEB-INF/classes/http_client.json:g" config.properties
sed -i "s:../logs/log4j.log:/var/lib/tomcat8/logs/log4j.log:g" log4j.properties #通过log监控平台状态
service tomcat8 restart
二、配置 vjudge
安装后几个重要配置文件的位置如下：
/var/lib/tomcat8/webapps/vjudge/WEB-INF/classes/config.properties
/var/lib/tomcat8/webapps/vjudge/WEB-INF/classes/remote_accounts.json #设置各OJ网站的账号和密码。
三、修改 tomcat 默认根目录
编辑Tomcat配置文件var/lib/tomcat8/conf/server.xml，在host标签之间加入如下标签：
<Context path="" docBase="vjudge" debug="0" reloadable="true" />
