2019-12-01 作者:办公软件   |   浏览(146)

本人01-06年就职于阿里巴巴,还算精通电子商务网站的运作全过程,现在上海创办好教练网,因项目扩张,特在此寻找技术高手加盟,希望搭建起6-8人的技术团队。

一.Tomact简介

JEESZ分布式架构1--CentOs下安装jdk7(环境准备),1--centosjdk7

声明:因为运行环境是基于Linux系统的,在做此框架之前需要做一些前期的环境准备工作
CentOs下安装jdk7网上很多实例,因为博客后期作为框架的原生教程,故这边做详细的安装记录

首 先在CentOs下下载jdk7解压文件,tar包安装(目前Oracle官方上,对于文件的下载,加了Cookie验证机制,所以直接下载文件包,会出 现找不到的错误,最老土的办法,本地下载,使用FTP上传服务器),我这边已经下载好了,通过ssh已经上传到指定的目录,这里直接讲解安装的过程。

一、准备工作 
卸载OpenJDK
1.查找需要卸载的OpenJDK
[[email protected] /] rpm -qa |grep openjdk | grep -v grep 
Java-1.7.0-openjdk-1.7.0.75-2.5.4.2.el7_0.x86_64 
java-1.6.0-openjdk-devel-1.6.0.34-1.13.6.1.el7_0.x86_64 
java-1.7.0-openjdk-headless-1.7.0.75-2.5.4.2.el7_0.x86_64 
java-1.6.0-openjdk-1.6.0.34-1.13.6.1.el7_0.x86_64

java-1.7.0-openjdk-devel-1.7.0.75-2.5.4.2.el7_0.x86_64

2.依次卸载

[[email protected] /] rpm -e --nodepsjava-1.7.0-openjdk-1.7.0.75-2.5.4.2.el7_0.x86_64 
[[email protected] /] rpm -e–nodeps java-1.6.0-openjdk-devel-1.6.0.34-1.13.6.1.el7_0.x86_64 
[[email protected] /] rpm -e–nodeps java-1.7.0-openjdk-headless-1.7.0.75-2.5.4.2.el7_0.x86_64 
[[email protected] /] rpm -e–nodeps java-1.6.0-openjdk-1.6.0.34-1.13.6.1.el7_0.x86_64 
[[email protected] /] rpm -e –nodepsjava-1.7.0-openjdk-devel-1.7.0.75-2.5.4.2.el7_0.x86_64 
注:权限不足,请使用su root权限

二、安装配置JDK7

1.解压安装jdk文件

[[email protected] /] tar-zxvf jdk-7u75-linux-x64.tar.gz 
./jdk1.7.0_45/jre/lib/management/snmp.acl.template
./jdk1.7.0_45/jre/lib/logging.properties
...
...
...
./jdk1.7.0_45/db/LICENSE
./jdk1.7.0_澳门新萄京官方网站,45/db/NOTICE
./jdk1.7.0_45/db/3RDPARTY
./jdk1.7.0_45/db/README-JDK.html
[[email protected] tools]# ls
jdk1.7.0_45  jdk1.7.0_45.tar.gz
[[email protected] tools]# mkdir /usr/java
[[email protected] tools]# mv jdk1.7.0_45/ /home/java/jdk1.7
[[email protected] tools]# rm -rf . jdk1.7.0_45

2.配置JDK7
编辑/etc/profile文件
[[email protected] jdk1.7]# vi /etc/profile
在/etc/profile文件尾部添加
export JAVA_HOME=/usr/java/1.7.0_45
exportCLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin
使用source /etc/profile命令重新加载/etc/profile文件,使修改的内容在当前shell窗口中生效

三、测试
[[email protected] ~]# java -version
Java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

表示已经安装成功~~~

前几天把windows下j2ee的运行环境搭建好了。因为公司服务器用的都是linux,所以今天把在linux下j2ee的运行环境也搭建一下。下面是我全部测试ok的详细日记:

Hadoop的Client搭建-即集群外主机访问Hadoop

Hadoop的Client搭建-即集群外主机访问Hadoop

1、增加主机映射(与namenode的映射一样):

增加最后一行

[[email protected] ~]# su - root

[[email protected] ~]# vi /etc/hosts
127.0.0.1  localhost localhost.localdomain localhost4 localhost4.localdomain4
::1        localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.48.129    hadoop-master
[[email protected] ~]#

2、新建用户hadoop

建立hadoop用户组

新建用户,useradd -d /usr/hadoop -g hadoop -m hadoop (新建用户hadoop指定用户主目录/usr/hadoop 及所属组hadoop)

passwd hadoop 设置hadoop密码(这里设置密码为hadoop)

[[email protected] ~]# groupadd hadoop 
[[email protected] ~]# useradd -d /usr/hadoop -g hadoop -m hadoop
[[email protected] ~]# passwd hadoop

3、配置jdk环境

本次安装的是hadoop-2.7.5,需要JDK 7以上版本。若已安装可跳过。

JDK安装可参考: 或 CentOS7.2安装JDK1.7 

或者直接拷贝master上的JDK文件更有利于保持版本的一致性。

[[email protected] java]# su - root
[[email protected] java]# mkdir -p /usr/java
[[email protected] java]# scp -r [email protected]:/usr/java/jdk1.7.0_79 /usr/java
[[email protected] java]# ll
total 12
drwxr-xr-x. 8 root root 4096 Feb 13 01:34 default
drwxr-xr-x. 8 root root 4096 Feb 13 01:34 jdk1.7.0_79
drwxr-xr-x. 8 root root 4096 Feb 13 01:34 latest

设置Java及hadoop环境变量

确保/usr/java/jdk1.7.0.79存在

su - root

vi /etc/profile

确保/usr/java/jdk1.7.0.79存在

unset i
unset -f pathmunge
JAVA_HOME=/usr/java/jdk1.7.0_79
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
PATH=/usr/hadoop/hadoop-2.7.5/bin:$JAVA_HOME/bin:$PATH

设置生效(重要)

[[email protected] ~]# source /etc/profile
[[email protected] ~]#

JDK安装后确认:

[[email protected] ~]$ java -version
java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)
[[email protected] ~]$

4、设置hadoop的环境变量

拷贝namenode上已配置好的hadoop目录到当前主机

[[email protected] ~]# su - hadoop
Last login: Sat Feb 24 14:04:55 CST 2018 on pts/1
[[email protected] ~]$ pwd
/usr/hadoop
[[email protected] ~]$ scp -r [email protected]:/usr/hadoop/hadoop-2.7.5 .
The authenticity of host 'hadoop-master (192.168.48.129)' can't be established.
ECDSA key fingerprint is 1e:cd:d1:3d:b0:5b:62:45:a3:63:df:c7:7a:0f:b8:7c.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'hadoop-master,192.168.48.129' (ECDSA) to the list of known hosts.
[email protected]'s password:

[[email protected] ~]$ ll
total 0
drwxr-xr-x  2 hadoop hadoop  6 Feb 24 11:32 Desktop
drwxr-xr-x  2 hadoop hadoop  6 Feb 24 11:32 Documents
drwxr-xr-x  2 hadoop hadoop  6 Feb 24 11:32 Downloads
drwxr-xr-x 10 hadoop hadoop 150 Feb 24 14:30 hadoop-2.7.5
drwxr-xr-x  2 hadoop hadoop  6 Feb 24 11:32 Music
drwxr-xr-x  2 hadoop hadoop  6 Feb 24 11:32 Pictures
drwxr-xr-x  2 hadoop hadoop  6 Feb 24 11:32 Public
drwxr-xr-x  2 hadoop hadoop  6 Feb 24 11:32 Templates
drwxr-xr-x  2 hadoop hadoop  6 Feb 24 11:32 Videos
[[email protected] ~]$

到此,Hadoop的客户端安装就算完成了,接下来就可以使用了。

执行hadoop命令结果如下,

[[email protected] ~]$ hadoop
Usage: hadoop [--config confdir] [COMMAND | CLASSNAME]
  CLASSNAME            run the class named CLASSNAME
 or
  where COMMAND is one of:
  fs                  run a generic filesystem user client
  version              print the version
  jar <jar>            run a jar file
                      note: please use "yarn jar" to launch
                            YARN applications, not this command.
  checknative [-a|-h]  check native hadoop and compression libraries availability
  distcp <srcurl> <desturl> copy file or directories recursively
  archive -archiveName NAME -p <parent path> <src>* <dest> create a hadoop archive
  classpath            prints the class path needed to get the
  credential          interact with credential providers
                      Hadoop jar and the required libraries
  daemonlog            get/set the log level for each daemon
  trace                view and modify Hadoop tracing settings

Most commands print help when invoked w/o parameters.
[[email protected] ~]$

5、使用hadoop

创建本地文件

[[email protected] ~]$ hdfs dfs -ls
Found 1 items
drwxr-xr-x  - hadoop supergroup          0 2018-02-22 23:41 output
[[email protected] ~]$ vi my-local.txt
hello boy!
yehyeh

上传本地文件至集群

[[email protected] ~]$ hdfs dfs -mkdir upload
[[email protected] ~]$ hdfs dfs -ls upload
[[email protected] ~]$ hdfs dfs -ls
Found 2 items
drwxr-xr-x  - hadoop supergroup          0 2018-02-22 23:41 output
drwxr-xr-x  - hadoop supergroup          0 2018-02-23 22:38 upload
[[email protected] ~]$ hdfs dfs -ls upload
[[email protected] ~]$ hdfs dfs -put my-local.txt upload
[[email protected] ~]$ hdfs dfs -ls upload
Found 1 items
-rw-r--r--  3 hadoop supergroup        18 2018-02-23 22:45 upload/my-local.txt
[[email protected] ~]$ hdfs dfs -cat upload/my-local.txt
hello boy!
yehyeh
[[email protected] ~]$

ps:注意本地java版本与master拷贝过来的文件中/etc/hadoop-env.sh配置的JAVA_HOME是否要保持一致没有验证过,本文是保持一致的。

有效期:截止到2011年年底!

1.tomact是apache软件基金会的一个核心项目。由apache、SUN和其他的一些公司及个人共同研发的;tomact是一个开放源代码,运行servlet和JSP Web应用软件的基于Java的Web应用软件容器;;tomact是小型的轻量级应用服务器,适用于小型和中型系统或者是访问用户不是特别多的情况。

一、JDK安装(安装在/usr/java目录下)

公司创办已3年了,目前已过了初创期,进入成长期了。我们属于“教育及培训行业”,公司主营“生活教练、企业教练和体育教练”行业,目前主营业务为学车教练。新加盟的同事主要精力在于开发新的行业。公司的项目前景没有问题公司愿与同事一起分享劳动成果!热爱代码,能实际撰写优雅的源码,喜欢将复杂的事情简单化喜欢数学,喜欢数据库,逻辑思维强语言不限制,不管你用net还是php还是java皆可(但网站的前台暂时不会应用java,本人有此后遗症)懂点架构设计、会折腾服务器配置、懂点项目管理、懂点技术员管理。在电子商务网站呆过优先考虑,懂搜索配置及排名的优先考虑

@1.servelet:server applet 服务器端的小程序

1、下载:jdk-7-ea-bin-b26-linux-i586-24_apr_2008.bin
地址:
windows下将zip格式的解压出jdk-7-ea-bin-b26-linux-i586-24_apr_2008.bin
再传到linux服务器的/usr/java目录下

第一年的现金及期权的比例需面谈,因人而异,

@2.servelet容器:管理和运行servelet的。

2、给文件加上可执行权限
[[email protected] java]# chmod x jdk-7-ea-bin-b26-linux-i586-24_apr_2008.bin

公司地址:8号线江月路地铁站旁QQ:56740701msn:[email protected]gtalk: [email protected]简历投递:[email protected]本人微博:www.weibo.com/caohanmin好教练网创始人:大曹

优势:能够很好的处理动态页面,跨平台也不错。JSP

3.执行jdk-7-ea-bin-b26-linux-i586-24_apr_2008.bin
[[email protected] java]# ./jdk-7-ea-bin-b26-linux-i586-24_澳门新萄京官方网站:Linux下哪些搭建j2ee的运作情况,apache实现web网页动静结合。apr_2008.bin
自动安装生成目录jdk1.7.0

缺点:处理静态页面缓慢,配置文件的可配置性不强。

4.配置环境变量
环境变量配置有三种方法分别是:修改/etc/profile文件,修改用户目录下的.bashrc文件,直接在shell下修改)我修改了/etc/profile文件:
[[email protected] java]# vi /etc/profile
打开文件后,按i 键,在文件后添加:

2.JSP:是一种以java作为脚本语言些的一个服务于http的应用程序

JAVA_HOME=/usr/java/jdk1.7.0
PATH=$JAVA_HOME/bin:$PATH
CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar
export JAVA_HOME PATH CLASSPATH

3.安装tomcat需要的软件包

按esc 键
输入:wq 保存退出。
重新启动服务器

apache-tomcat-6.0.16.tar.gz

6.测试配置环境
写个简单的HelloWorld来测试一下
[[email protected] java]# vi HelloWorld.java
文件中输入:

jakarta-tomcat-connectors-jk2-2.0.4-src.tar.gz

public class HelloWorld{
public static void main(String args[]){
System.out.println(”Hello World in Linux!!”);
}
}

jdk-1_5_0_16-linux-i586.bin

:wq 保存退出
[[email protected] java]# javac HelloWorld.java
没有错误,接下来:
[[email protected] java]# java HelloWorld
shell下输出:

JiveForumsPro4_crack.tar.gz

Exception in thread “main” java.lang.NoClassDefFoundError: HelloWorld/java
Caused by: java.lang.ClassNotFoundException: HelloWorld.java

Error: Could not find the main class.
Error: A JNI error has occurred, please check your installation and try again

mysql-connector-java-3.1.14.tar.gz

(上面问题是何原因,但是好像不影响下面jsp的运行 ^_^ 姑且算作jdk安装成功吧。)

二.具体配置

二、tomcat安装:(同样安装在/usr/java目录下)
下载地址:

1.部署java环境

1、解压到/usr/java目录:
[[email protected] java]# tar -zxvf jakarta-tomcat-5.0.28.tar.gz

[[email protected] ~]# vim /etc/profile//设置一些path路径

5、浏览器中输入: 将出现tomcat欢迎页面 ^_^

JAVA_HOME=/usr/local/java

6、管理tomcat:
[[email protected] tomcat]# vi conf/tomcat-users.xml
在和之间加入:

PATH=$JAVA_HOME/bin:$PATH

7、重启系统:
浏览器中输入: 登入后就可以来管理了
输入 来管理你的工程项目了

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

  1. Linux中利用系统库文件来降低工作量
  2. 检测在Linux系统下U盘是否已连接的方法
  3. Linux EXT3下删除MySQL数据库的数据恢复

export JAVA_HOME PATH CLASSPATH

...

[uri:/jive/*]

info=map the tomcat

[uri:/manager/*]

info=map the tomcat

[uri:/*.jsp]

info=map the tomcat

[[email protected] apache2]# /etc/init.d/httpd restart

Stopping httpd: [OK ]

Starting httpd: [ OK ]

[[email protected] apache2]# shutdown.sh

Using CATALINA_BASE: /usr/local/tomcat

Using CATALINA_HOME: /usr/local/tomcat

Using CATALINA_TMPDIR: /usr/local/tomcat/temp

Using JRE_HOME: /usr/local/java

[[email protected] apache2]# startup.sh

Using CATALINA_BASE: /usr/local/tomcat

Using CATALINA_HOME: /usr/local/tomcat

Using CATALINA_TMPDIR: /usr/local/tomcat/temp
