怎么部署java项目（从搭建环境说起）

Posted 2020-08-15 秋寻草

1、服务器需要安装对应开发版本的jdk

在官网下载jdk对应的jdk版本，解压到某个目录下如:

[email protected]:/home/guchen/usr/java# ls
jdk1.8.0_111  jdk-8u111-linux-x64.tar.gz

 

解压命令 tar -xzvf jdk-8u111-linux-x64.tar.gz

2.进入 vi /etc/profile 中添加环境变量如下：

1 #jdk1.8.0._111
2 JAVA_HOME=/home/guchen/usr/java/jdk1.8.0_111
3 JRE_HOME=/home/guchen/usr/java/jdk1.8.0_111/jre
4 MAVEN_HOME=/home/guchen/usr/local/apache-maven-3.3.9
5 PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin:$MAVEN_HOME/bin
6 CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
7 export JAVA_HOME JRE_HOME MAVEN_HOME PATH CLASSPATH

保存退出后使环境变量生效，执行：source /etc/profile

3、安装tomcat

下载tomcat，并解压到某个目录下如：

[email protected]:/home/guchen/usr/local# ls
apache-maven-3.3.9  apache-maven-3.3.9-bin.tar.gz  apache-tomcat-7.0.72  apache-tomcat-7.0.72.tar.gz

4、把war包放进webapps下面重启tomcat就ok啦

[email protected]:/home/guchen/usr/local/apache-tomcat-7.0.72/webapps# ls
docs  examples  host-manager  jenkins  jenkins.war  manager  operation-centre  operation-centre.war  ROOT

进入到bin目录下重启tomcat，执行命令 ./startup.sh

[email protected]:/home/guchen/usr/local/apache-tomcat-7.0.72/bin# ./startup.sh 
Using CATALINA_BASE:   /home/guchen/usr/local/apache-tomcat-7.0.72
Using CATALINA_HOME:   /home/guchen/usr/local/apache-tomcat-7.0.72
Using CATALINA_TMPDIR: /home/guchen/usr/local/apache-tomcat-7.0.72/temp
Using JRE_HOME:        /home/guchen/usr/java/jdk1.8.0_111/jre
Using CLASSPATH:       /home/guchen/usr/local/apache-tomcat-7.0.72/bin/bootstrap.jar:/home/guchen/usr/local/apache-tomcat-7.0.72/bin/tomcat-juli.jar
Tomcat started.
[email protected]-ubuntu16-04lts:/home/guchen/usr/local/apache-tomcat-7.0.72/bin#

网址输入IP:8080

如果出现tomcat首页则说明安装ok
