Ubuntu 安装java环境搭建

1、下载JDK 8
从http://www.oracle.com/technetwork/java/javasebusiness/downloads/选择下载JDK的最新版本 JDK 8。

2、解压文件
$ sudo mkdir /usr/lib/jvm
$ sudo mv jdk-8u11-linux-x64.tar.gz /usr/lib/jvm/

$ cd /usr/lib/jvm/
$ sudo tar -zxvf jdk-8u11-linux-x64.tar.gz
$ rm ./jdk-8u11-linux-x64.tar.gz

3、配置

$ sudo gedit /etc/environment

报错:(gedit:7473): Gtk-WARNING **: cannot open display:

运行xhost +

xhost:  unable to open display ""

总之用网上各种方法均不见效，最后用vim /etc/environmen

JAVA_HOME="/usr/lib/jvm/jdk1.8.0_11"

CLASSPATH=".:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar"

然后就是要告诉系统，我们使用的sun的JDK，而非OpenJDK了：

sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.8.0_11/bin/java 300

sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.8.0_11/bin/javac 300

4. 测试一下运行 java -version

root@iZ23htt4xm4Z:/etc# java -version
java version "1.8.0_11"
Java(TM) SE Runtime Environment (build 1.8.0_11-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.11-b03, mixed mode)

java安装完成下一步

下载安装最新版本的Tomcat

从tomcat的官方下载页面

http://tomcat.apache.org/download-70.cgi

下载Binary->Core分类中的zip或者tar.gz包后，本地解压缩并将新生成的目录重命名为tomcat，以方便使用。将这个文件夹移动至某路径PATH/。 参考以上设置环境变量和端口设置等步骤，大功告成！ 直接运行

PATH/tomcat/bin/./startup.sh

Tomcat 便即刻在后台服务了。 （请将PATH替换成适合您的路径）

下载maven

设置环境变量

 M2_HOME=/home/weibo/apache-maven-3.0.5
 M2=$M2_HOME/bin
 PATH=$M2:$PATH

保存

source /etc/environmen

测试

mvn -version

官网下载httpd-2.4.10.tar.gz

$ gzip -d httpd-2.4.10.tar.gz
$ tar xvf httpd-2.4.10.tar.gz
$ cd httpd-2.4.10.tar.gz

./configure --prefix=/usr/lib/jvm/apache

用Apache搭www服务时“APR not found”（APR-Util not found）的解决办法

原来以为很简单的事，操作起来还是会遇到很多问题，这个问题很典型，调出来与大家分享。

#./configure —prefix……检查编辑环境时出现：
checking for APR… no
configure: error: APR not found .  Please read the documentation.

可以用./configure –help | grep apr 查看帮助。
—with-included-apr     Use bundled copies of APR/APR-Util
—with-apr=PATH         prefix for installed APR or the full path to apr-config
—with-apr-util=PATH    prefix for installed APU or the full path to
安装APR(Apache Portable Runtime )
[root@localhost 52lamp]# tar -zxvf apr-1.5.1.tar.gz //unzip -o apr-apr-1.5.1.zip
[root@localhost 52lamp]# cd apr-apr-1.5.1
[root@localhost apr-1.5.1]# ./configure
[root@localhost apr-1.5.1]# make
[root@localhost apr-1.5.1]# make install

再次检查编译环境出现
checking for APR-util… no
configure: error: APR-util not found .  Please read the documentation.

[root@localhost  httpd-httpd-2.4.10]# ./configure –help | grep apr-util
—with-apr-util=PATH    prefix for installed APU or the full path to

[root@localhost 52lamp]# tar -zxvf apr-util-1.3.9.tar.gz
[root@localhost 52lamp]# cd apr-util-1.3.9
[root@localhost apr-util-1.3.9]# ./configure —prefix=/usr/local/apr-util —with-apr=/usr/local/apr
[root@localhost apr-util-1.3.9]# make
[root@localhost apr-util-1.3.9]# make install

./configure仍提示APR-util not found，增加—with-apr=/usr/local/apr —with-apr-util=/usr/local/apr-util后出现
configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/

[root@localhost  httpd-2.4.10]# ./configure –help | grep pcre
—with-pcre=PATH        Use external PCRE library

[root@localhost 52lamp]# unzip -o pcre-8.10.zip
[root@localhost 52lamp]# cd pcre-8.10
[root@localhost cd pcre-8.35]# ./configure —prefix=/usr/local/pcre
[root@localhost cd pcre-8.35]# make
[root@localhost cd pcre-8.35]# make install

继续安装Apache/httpd，./configure 时加上参数 —with-apr=/usr/local/apr/ —with-apr-util=/usr/local/apr-util/ —with-pcre=/usr/local/pcre，这个问题就解决了。
