我看你什么脚本都试了，你是自己打包的吗？另外看上去操作系统是linux的，请对o2server目录赋权比如：chmod 755 -R o2server，如果是centeros启动执行运行：./start_linux.sh，如果是Ubuntu前面加sudo

上个问题是文件格式不是unix的，我解决了。但是脚本运行的时候

/root/O2OA/target/o2server/jvm/linux_java11/bin/java: error while loading shared libraries: libjli.so: cannot open shared object file: No such file or directory


这个我检查一下脚本是unix的，不是格式问题，权限也是没问题的
