tomcat+java环境linux安装

最近要加一个环境测试,自力更生,丰衣足食,记下来下次安装环境速度快点

java jdk-1.80_131 64位  

这个jdk 对于初次下载的人要注意,oracel现在不登录不让下载,而注册用户时页面无反应,应该是关闭了接口.可以在百度上搜个别人共享的账号使用.

输入：javac –version 查看服务器上，当前默认的jdk 版本

[root@sxora01 ~]# java -version
java version "1.7.0_45"
OpenJDK Runtime Environment (rhel-2.4.3.3.el6-x86_64 u45-b15)
OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)

　 再输入：rpm -qa|grep java       卸载

[root@sxora01 ~]# rpm -qa|grep java
java-1.6.0-openjdk-devel-1.6.0.0-1.66.1.13.0.el6.x86_64
java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64
tzdata-java-2013g-1.el6.noarch
java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.x86_64
libvirt-java-devel-0.4.9-1.el6.noarch
java-1.7.0-openjdk-devel-1.7.0.45-2.4.3.3.el6.x86_64
libvirt-java-0.4.9-1.el6.noarch

　这个时候，我们可以看到linux 默认java 版本，但是现在我们想使用jdk 1.8 那么我们就要去卸载默认的版本

2 安装jdk
在usr下面新建一个Java目录 然后在Java下面新建一个jdk文件夹和tomcat文件夹

[root@iZj1fkye8uu7o0Z ~]# cd /usr
[root@iZj1fkye8uu7o0Z usr]# ls
bin etc games include java lib lib64 libexec local sbin share src tmp
[root@iZj1fkye8uu7o0Z usr]# cd java
[root@iZj1fkye8uu7o0Z java]# ls
jdk tomcat
创建目录的命令mkdir java 和mkdir tomcat 分别用于解压jdk 和tomcat
[root@localhost ~]# cd /usr/
[root@localhost usr]# mkdir java
[root@localhost usr]# cd java/
[root@localhost java]# mkdir jdk
[root@localhost java]# cd jdk
然后将刚刚下载的jdk解压到dk目录下面

执行解压命令（如果不是此版，不要忘记根据文件名更改）注意这里的-C为大写

[root@iZj1fkye8uu7o0Z ~]# tar -xvf jdk-8u131-linux-x64.tar.gz -C /usr/java/jdk
解压完后 进入到/usr/java/jdk下面可以查看到 刚刚解压的文件

[root@iZj1fkye8uu7o0Z ~]# cd /usr/java/jdk
[root@iZj1fkye8uu7o0Z jdk]# ls
jdk1.8.0_131
[root@iZj1fkye8uu7o0Z jdk]#
配置环境变量
在etc 的profile里面配置环境变量

[root@iZj1fkye8uu7o0Z ~]# vi /etc/profile
#set java enviroment
export JAVA_HOME=/usr/java/jdk/jdk1.8.0_131
export JRE_HOME=/usr/java/jdk/jdk1.8.0_131/jre
export CLASSPATH=.:$JAVA_HOME/lib$:JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin/$JAVA_HOME:$PATH

注意：这里的jdk名称和自己下载的jdk名称版本一致 我是用的是jdk1.8.0_131

保存退出。

到目前为止安装jdk的工作都已经完成，那么就来测试一下是否安装成功了吧

[root@iZj1fkye8uu7o0Z ~]# java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)
[root@iZj1fkye8uu7o0Z ~]#

现在，我们再来安装tomcat

cd /usr 进入 usr 目录

mkdir tomcat 创建tomcat 文件夹

mv apache-tomcat-8.0.39.tar.gz  /usr/tomcat 将tomcat 包移动到tomcat里面

tar -xvzf apache-tomcat-8.0.39.tar.gz 进行解压

[root@sxweb tomcat]# mv apache-tomcat-8.0.39/* /usr/tomcat
[root@sxweb tomcat]# ll
total 9204
drwxr-xr-x 2 root root 4096 Jan 5 10:24 apache-tomcat-8.0.39
-rw-r--r-- 1 root root 9304967 Dec 27 17:16 apache-tomcat-8.0.39.tar.gz
drwxr-xr-x 2 root root 4096 Jan 5 10:24 bin
drwxr-xr-x 2 root root 4096 Nov 9 16:53 conf
drwxr-xr-x 2 root root 4096 Jan 5 10:24 lib
-rw-r--r-- 1 root root 57011 Nov 9 16:53 LICENSE
drwxr-xr-x 2 root root 4096 Nov 9 16:48 logs
-rw-r--r-- 1 root root 1444 Nov 9 16:53 NOTICE
-rw-r--r-- 1 root root 6741 Nov 9 16:53 RELEASE-NOTES
-rw-r--r-- 1 root root 16195 Nov 9 16:53 RUNNING.txt
drwxr-xr-x 2 root root 4096 Jan 5 10:24 temp
drwxr-xr-x 7 root root 4096 Nov 9 16:50 webapps
drwxr-xr-x 2 root root 4096 Nov 9 16:48 work
[root@sxweb tomcat]# cd apache-tomcat-8.0.39
[root@sxweb apache-tomcat-8.0.39]# ll
total 0
 

执行后，在将解压文件夹内容移出到tomcat 目录下

删除空文件夹

[root@sxweb tomcat]# rm -rf apache-tomcat-8.0.39
 cp /usr/tomcat/bin/catalina.sh /etc/init.d/tomcat

 将catalina.sh 复制成/etc/init.d/tomcat

在对该文件进行编辑

[root@sxweb ~]# cd /etc/init.d
[root@sxweb init.d]# vim tomcat
 在文件中加入，我下段全部内容

# chkconfig: 2345 63 37
# description: tomcat server init script
# Source Function Library
. /etc/init.d/functions
JAVA_HOME=/usr/java/jdk1.8.0_111
CATALINA_HOME=/usr/tomcat
 

注释掉的也要加上，不要漏掉

完整:

#!/bin/sh
# chkconfig: 2345 63 37
# description: tomcat server init script
# Source Function Library
. /etc/init.d/functions
JAVA_HOME=/usr/java/jdk1.8.0_111
CATALINA_HOME=/usr/tomcat

"tomcat" 619L, 22616C
 然后执行

[root@tomcat ~]# chmod 755 /etc/init.d/tomcat 
[root@tomcat ~]# chkconfig --add tomcat
[root@tomcat ~]# chkconfig tomcat on
启动tomcat
[root@tomcat ~]# service tomcat start      
停止tomcat
[root@tomcat ~]# service tomcat stop
