尝试解决：
安装 https 相关包
1. sudo apt install apt-transport-https2. sudo apt install ca-certificates3. sudo apt-get update
2. ubuntu jenkins 修改默认启动端口（8080 => 9090）
有很多博客记录修改方式是：
1. 修改 sudo vim /etc/init.d/jenkins
# Verify that the jenkins port is not already in use, winstone does not exit
# even for BindExceptioncheck_tcp_port "http" "${HTTP_PORT}" "8080" "${HTTP_HOST}" "0.0.0.0" || return 22. 修改 sudo vim /etc/default/jenkins
# port for HTTP connector (default 8080; disable with -1)
HTTP_PORT=8080
比较尴尬，并没有生效。

一样的朋友可以试下下面的方式：
1. ps -def | grep java (查看 java 相关进程信息 )heze@heze:/etc/default$ ps -def | grep java
jenkins 91470 1 99 09:54 ? 00:00:31 /usr/bin/java -Djava.awt.headless=true -jar /usr/share/java/jenkins.war --webroot=/var/cache/jenkins/war --httpPort=8080
heze 91625 88963 0 09:54 pts/1 00:00:00 grep --color=auto java2. systemctl status jenkins （查看 jenkins 状态）heze@heze:/etc/default$ systemctl status jenkins

3. 安装tomcat
1. 下载 tomcat 包文件 wget http://dlcdn.apache.org/tomcat/tomcat-9/v9.0.64/src/apache-tomcat-9.0.64-src.tar.gz2. 解压文件 tar -zxvf apache-tomcat-9.0.64-src.tar.gz3. 文件夹重命名mv ./apache-tomcat-9.0.64-src ./tomcat9.0cd tomcat9.04. 编辑 ./bin 目录下 (shutdown.sh、startup.sh) 文件中最后分别加入：#tomcatexport TOMCAT=/tomcat/apache-tomcat-8.5.75export JAVA_HOME=/jdk/jdk1.8.0_291export JRE_HOME=${JAVA_HOME}/jreexport CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/libexport PATH=${JAVA_HOME}/bin:$PATH5. 启动：./startup.sh6. 关闭：./shutdown.sh7. 默认端口 8080，可以通过浏览器访问 http://127.0.0.1:80808. 修改默认端口 port="8080" 修改成你自定义端口即可vim ./tomcat9.0/conf/server.xml9. 重启后使用新端口访问4. 安装phpstorm
1. 下载工具包文件wget https://download.jetbrains.com.cn/webide/PhpStorm-2022.1.3.tar.gz2. 解压文件tar -zxvf PhpStorm-2022.1.3.tar3. move 文件夹到合适的位置mv ./PhpStorm-2022.1.3 /opt/phpstorm20224. 创建软连接ln -s /opt/phpstorm2022/bin/phpstorm.sh /usr/local/bin/phpstorm6. 激活 phpstorm激活码获取：传送门(http://idea.lanyus.com)
5. phpstorm 添加桌面快捷方式
1. 查找 phpstorm.sh 的位置whereis phpstorm|grep ".sh"2. 创建快捷方式vim /usr/share/applications/phpstorm.desktop文件内容：
* 注意文件路径是否需要替换[Desktop Entry]Type=ApplicationName=PhpstormGenericName=PhpstormComment=PhpstormExec="/opt/phpstorm/bin/phpstorm.sh" %fIcon=/opt/phpstorm/bin/phpstorm.pngTerminal=phpstormCategories=phpstorm
