初始化环境

目录初始化

## 可省略直接--add-to-start
java -jar $JETTY_HOME/start.jar --create-startd
java -jar $JETTY_HOME/start.jar --add-to-start=jvm,deploy,server,jsp,jstl,gzip,ext,http,servlets,session-store-mongo,slf4j-log4j2

在jetty.sh中设置

JETTY_BASE=$(cd $(dirname $0);pwd)
NAME=$(basename $JETTY_BASE)
JETTY_PID=${JETTY_BASE}/${NAME}.pid
JETTY_STATE=${JETTY_BASE}/${NAME}.state

更新日志配置

mkdir $JETTY_BASE/resources -p
touch $JETTY_BASE/resources/log4j2.xml
cat > ./resources/log4j2.xml <<END
