报错情况

社区开发版安装过程中报错，报错详情显示“systemctl start transwarp-aquila-server.service”失败，没有更多信息了，手动执行systemctl restart transwarp-aquila-server@aquila.service还是无法启动。

排查步骤

查看/var/log/aquila/server/aquila-server.log日志，日志显示报错信息：“...Failed to instantiate [org.springframework.validation.Validator]: Factory method 'getValidator' threw exception; nested exception is javax.validation.ValidationException: HV000183: Unable to initialize 'javax.el.ExpressionFactory'. Check that you have the EL dependencies on the classpath, or use ParameterMessageInterpolator instead...”

失败原因

该报错有可能是跟宿主机的操作系统加载顺序有关

解决方法

修改文件：/usr/lib/aquila/aquila-server/bin/boot.sh

修改成：

#CLASSPATH=${AQUILA_SERVER_HOME}/lib/*:${AQUILA_SERVER_HOME}/web:${JAVA_HOME}/lib/tools.jar

for jar in `find ${AQUILA_SERVER_HOME}/lib/ -name "*.jar" | sort`
do
   CLASSPATH="$CLASSPATH:$jar"
done
CLASSPATH=${CLASSPATH}:${AQUILA_SERVER_HOME}/web:${JAVA_HOME}/lib/tools.jar
