Ubuntu16.04安装jdk，下载linux中的64版本
需要下载jdk，tomcat安装包 tar.gz版本的

安装JDK:
hongdada@ubuntu:~$ sudo mkdir /java [sudo] hongdada 的密码： hongdada@ubuntu:~$ cd /Downloads bash: cd: /Downloads: 没有那个文件或目录 hongdada@ubuntu:~$ cd Downloads/ hongdada@ubuntu:~/Downloads$ sudo mv jdk-8u121-linux-x64.tar.gz /java hongdada@ubuntu:~/Downloads$ sudo tar -zxvf jdk-8u121-linux-x64.tar.gz tar (child): jdk-8u121-linux-x64.tar.gz：无法 open: 没有那个文件或目录 tar (child): Error is not recoverable: exiting now tar: Child returned status 2 tar: Error is not recoverable: exiting now hongdada@ubuntu:~/Downloads$ cd java/ bash: cd: java/: 没有那个文件或目录 hongdada@ubuntu:~/Downloads$ cd ~ hongdada@ubuntu:~$ cd java/ bash: cd: java/: 没有那个文件或目录 hongdada@ubuntu:~$ cd /java hongdada@ubuntu:/java$ sudo tar -zxvf jdk-8u121-linux-x64.tar.gz jdk1.8.0_121/ jdk1.8.0_121/THIRDPARTYLICENSEREADME-JAVAFX.txt jdk1.8.0_121/THIRDPARTYLICENSEREADME.txt ............... jdk1.8.0_121/man/ja_JP.UTF-8/man1/jstat.1 hongdada@ubuntu:/java$ sudo gedit /etc/environment //修改/etc/environment中的内容 hongdada@ubuntu:~$ sudo gedit /etc/environment [sudo] hongdada 的密码： (gedit:3856): IBUS-WARNING **: The owner of /home/hongdada/.config/ibus/bus is not root!

/etc/environment中文件修改为
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:$JAVA_HOME/bin" export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib export JAVA_HOME=/java/jdk1.8.0_121
修改environment是修改系统的环境变量，还要修改登陆用户的环境变量，即修改/etc/profile的文件
hongdada@ubuntu:~$ sudo gedit /etc/profile
/etc/profile修改为：
# /etc/profile: system-wide .profile file for the Bourne shell (sh(1)) # and Bourne compatible shells (bash(1), ksh(1), ash(1), ...). if [ "$PS1" ]; then if [ "$BASH" ] && [ "$BASH" != "/bin/sh" ]; then # The file bash.bashrc already sets the default PS1. # PS1='h:w$ ' if [ -f /etc/bash.bashrc ]; then . /etc/bash.bashrc fi else if [ "`id -u`" -eq 0 ]; then PS1='# ' else PS1='$ ' fi fi fi if [ -d /etc/profile.d ]; then for i in /etc/profile.d/*.sh; do if [ -r $i ]; then . $i fi done unset i fi #set java environment export JAVA_HOME=/java/jdk1.8.0_121 export JRE_HOME=$JAVA_HOME/jre export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
使用命令使环境变量立即生效
source /etc/profile
重启电脑，能正常进入系统，且java -version命令有效
安装Tomcat9:
在java文件夹下面创建文件夹tomcat,迁移Downloads中的apache-tomcat-9.0.0.M17.tar.gz文件到tomcat文件夹中，解压
修改/java/tomcat/apache-tomcat-9.0.0.M17/bin/startup.sh文件
在文件底部添加
#set java environment export JAVA_HOME=/java/jdk1.8.0_121 export JRE_HOME=$JAVA_HOME/jre export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH #tomcat export TOMCAT_HOME=/java/tomcat/apache-tomcat-9.0.0.M17
添加之后的startup.sh文件

启动Tomcat
hongdada@ubuntu:~$ cd /java hongdada@ubuntu:/java$ cd tomcat hongdada@ubuntu:/java/tomcat$ cd apache-tomcat-9.0.0.M17 hongdada@ubuntu:/java/tomcat/apache-tomcat-9.0.0.M17$ cd bin bash: cd: bin: 权限不够 hongdada@ubuntu:/java/tomcat/apache-tomcat-9.0.0.M17$ sudo cd bin sudo: cd：找不到命令 hongdada@ubuntu:/java/tomcat/apache-tomcat-9.0.0.M17$ sudo bin sudo: bin：找不到命令 hongdada@ubuntu:/java/tomcat/apache-tomcat-9.0.0.M17$ sudo ./bin/startup.sh Using CATALINA_BASE: /java/tomcat/apache-tomcat-9.0.0.M17 Using CATALINA_HOME: /java/tomcat/apache-tomcat-9.0.0.M17 Using CATALINA_TMPDIR: /java/tomcat/apache-tomcat-9.0.0.M17/temp Using JRE_HOME: /java/jdk1.8.0_121 Using CLASSPATH: /java/tomcat/apache-tomcat-9.0.0.M17/bin/bootstrap.jar:/java/tomcat/apache-tomcat-9.0.0.M17/bin/tomcat-juli.jar Tomcat started.
虚拟机的ip地址为192.168.1.202
查看tomcat
关闭tomcat,直接执行bin下面的shutdown.sh文件
hongdada@ubuntu:~$ cd /java hongdada@ubuntu:/java$ cd tomcat hongdada@ubuntu:/java/tomcat$ cd apache-tomcat-9.0.0.M17 hongdada@ubuntu:/java/tomcat/apache-tomcat-9.0.0.M17$ sudo ./bin/shutdown.sh [sudo] hongdada 的密码： Using CATALINA_BASE: /java/tomcat/apache-tomcat-9.0.0.M17 Using CATALINA_HOME: /java/tomcat/apache-tomcat-9.0.0.M17 Using CATALINA_TMPDIR: /java/tomcat/apache-tomcat-9.0.0.M17/temp Using JRE_HOME: /java/jdk1.8.0_121 Using CLASSPATH: /java/tomcat/apache-tomcat-9.0.0.M17/bin/bootstrap.jar:/java/tomcat/apache-tomcat-9.0.0.M17/bin/tomcat-juli.jar hongdada@ubuntu:/java/tomcat/apache-tomcat-9.0.0.M17$
为了每次能够在开机的时候自动启动tomcat
修改/etc/rc.local文件
#!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. #set java environment export JAVA_HOME=/java/jdk1.8.0_121 export JRE_HOME=$JAVA_HOME/jre export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH #tomcat export TOMCAT_HOME=/java/tomcat/apache-tomcat-9.0.0.M17 #configuration /java/tomcat/apache-tomcat-9.0.0.M17/bin/startup.sh
特别是#configuration下面的，用于自启动。
重启以后发现tomcat并没有自动启动，网上查看发现原来我的/etc/rc.local没有执行权限
hongdada@ubuntu:~$ ls -al /etc/rc.local -rw-rw-r-- 1 root root 628 3月 2 23:15 /etc/rc.local hongdada@ubuntu:~$ chmod +x /etc/rc.local chmod: 更改'/etc/rc.local' 的权限: 不允许的操作 hongdada@ubuntu:~$ sudo chmod +x /etc/rc.local hongdada@ubuntu:~$ ls -al /etc/rc.local -rwxrwxr-x 1 root root 628 3月 2 23:15 /etc/rc.local hongdada@ubuntu:~$
修改/etc/rc.local的执行权限，重启发现tomcat已经ok了。
