Jenkins+Tomcat服務(wù)器配置過程中，修改了tomcat配置文件；然后再訪問服務(wù)器的tomcat頁面發(fā)現(xiàn)根本加載不出來

企圖重啟tomcat

/opt/tomcat/bin/shutdown.sh

出現(xiàn)如下報錯

[root@izbp1fmfc2pdjiw9u143xfz conf]# /opt/tomcat/bin/shutdown.sh Using CATALINA_BASE: /opt/tomcat Using CATALINA_HOME: /opt/tomcat Using CATALINA_TMPDIR: /opt/tomcat/temp Using JRE_HOME: /usr/lib/jvm/java-1.8.0-openjdk Using CLASSPATH: /opt/tomcat/bin/bootstrap.jar:/opt/tomcat/bin/tomcat-juli.jar 二月 20, 2020 1:37:22 下午 org.apache.catalina.startup.Catalina stopServer 嚴重: Could not contact [localhost:8005].

經(jīng)查證，出現(xiàn)這種報錯的原因是Tomcat尚未啟動完成；

接下來嘗試了強制關(guān)閉tomcat

ps -ef | grep tomcat 查看tomcat進程號
kill -9 + 進程號 殺死進程

重新啟動tomcat

/opt/tomcat/bin/startup.sh

tomcat頁面依舊無法加載

打印tomcat運行日志

發(fā)現(xiàn)運行日志卡在最后一行：localhost-startStop-1，無法向下繼續(xù)進行

解決方案：

將$ JAVA_HOME / jre / lib / security / java.security文件中的securerandom.source參數(shù)修改為文件：/ dev /./ urandom

[root@izbp1fmfc2pdjiw9u143xfz logs]# cd $JAVA_HOME/jre/lib/security
[root@izbp1fmfc2pdjiw9u143xfz security]# ls
blacklisted.certs cacerts java.policy java.security nss.cfg policy
[root@izbp1fmfc2pdjiw9u143xfz security]# vi java.security

順帶一提，在vi中快速搜索的方法：

命令模式下輸入“/字符串”，例如“/Section 3”。如果查找下一個，按“n”即可。
