安装好xwiki，启动正常，但是重启xwiki，居然报错（本地虚拟机里面装的Linux系统）
我本地安装环境和xwiki对应的版本如下

centerOS: 7.9
xwiki: 13.10.6
jdk: 1.8.0_333
tomcat: 8.5.81
MySQL：5.7.24
jdbc driver: 5.1.48

上面日志是Tomcat的Catalina.out打印出来的，从错误中我们可以看到
在这里插入图片描述
好像某个文件被锁了，它也给说出了两个最可能的问题所在，一个是被另外一个程序占用着，无法删除；另一个是因为lockType设置为native，我进入/var/local/xwiki/data/store/solr/search/conf/，查看solr的配置配文件solrconfig.xml看到如下内容，这个从Solr3.6版本后就默认为native了，况且从Solr给的说明上也可以看出，对于我们这次的需求，这里使用native是合理的，那只有另外一个可能了，被占用了，看到这里我突然想到，之前遇到Tomcat关闭失败的问题。
在这里插入图片描述
先尝试临时解决方案，最后给出最终解决方案：
我进入这个目录后把.lock文件删除后，重启成功！
但是不能每次都进入这个目录删除，我执行shutdown.sh 停止Tomcat后，我查了下Java线程，如下图

在这里插入图片描述
于是我把这几个线程关闭掉，然后再重启，启动成功。
那这个原因是什么呢？总不能我们每次都要进行手动关闭吧？！具体的原因可以参考一个大佬的博文：Tomcat 启动后无法关闭的问题
解决办法有三个：（任选其一）
方法一：在catalina.sh中加入-Djava.security.egd=file:/dev/./urandom
方法二：打开$JAVA_PATH/jre/lib/security/java.security这个文件
securerandom.source=file:/dev/urandom
替换成
securerandom.source=file:/dev/./urandom

方法三：在Tomcat的bin目录下的catalina.sh中加入强制杀进程参考文章

我使用了第三种，前两种我的虚拟机没生效，第三种方式关闭重启，成功！
