此篇獻給初學者

一、環境介紹：

1、操作系統：CentOS 7.0 IP：192.168.137.128

2、JDK版本：jdk1.8.0_101

3、Tomcat版本：tomcat-9.0.0.M21

4、jenkins版本: Jenkins ver. 2.46.3

5、git版本：git version 2.9.4

6、maven版本：3.5.0

7、ant版本：version 1.10.1

二、環境部署

1、下載所需軟件包

# mkdir /tmp/soft ; cd /tmp/soft

##### tomcat

# wget http://apache.communilink.net/tomcat/tomcat-9/v9.0.0.M21/bin/apache-tomcat-9.0.0.M21.tar.gz

##### 下載git

# wget https://www.kernel.org/pub/software/scm/git/git-2.9.4.tar.gz

##### 下載jdk

# 下載地址：http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz

##### 下載maven

# wget http://ftp.cuhk.edu.hk/pub/packages/apache.org/maven/maven-3/3.5.0/binaries/apache-maven-3.5.0-bin.tar.gz

##### 下載jenkins

# wget http://mirrors.jenkins.io/war/latest/jenkins.war

##### 下載ant

# wget http://apache.communilink.net//ant/binaries/apache-ant-1.10.1-bin.tar.gz

2、安裝部署jdk

### 為了以後方便管理，將所有軟件安裝至/export/servers目錄下

a、解壓jdk

# tar -xf jdk-8u131-linux-x64.tar.gz -C /export/servers

b、配置環境變量

### 編輯/etc/profile文件，添加以下信息：

# vim /etc/profile

export JAVA_HOME=/export/servers/jdk1.8.0_131

export JAVA_BIN=$JAVA_HOME/bin

export PATH=$JAVA_HOME/bin:$PATH

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

export JAVA_OPTS="-Djava.library.path=/usr/local/lib -server -Xms1024m -Xmx2048m -XX:MaxPermSize=256m -Djava.awt.headless=true -Dsun.net.client.defaultReadTimeout=60000 -Djmagick.systemclassloader=no -Dnetworkaddress.cache.ttl=300 -Dsun.net.inetaddr.ttl=300"

export JAVA_HOME JAVA_BIN PATH CLASSPATH JAVA_OPTS

c、測試安裝是否成功

# 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)

3、安裝Tomcat

a、解壓Tomcat

# tar xf apache-tomcat-9.0.0.M21.tar.gz -C /export/servers

# mv /export/servers/apache-tomcat-9.0.0.M21 /export/servers/tomcat-9.0.0.M21

b、配置tomcat

###修改Tomcat字符集為UTF-8

# vim /export/servers/apache-tomcat-9.0.0.M21/conf/server.xml

# 修改為以下內容，添加URIEncoding：

<Connector port="8080" protocol="HTTP/1.1"

connectionTimeout="20000"

redirectPort="8443" URIEncoding="UTF-8" />

4、安裝jenkins

a、清理tomcat工作目錄

# cd /export/servers/tomcat-9.0.0.M21/webapps/ROOT/

# rm -rf *

b、解壓jenkins

# cp /tmp/soft/jenkins.war ./

# java -jar jenkins.war

5、安裝git

a、安裝依賴包

# cd /tmp/soft

# yum -y install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker

b、安裝git

# mkdir -p /export/servers/git-2.9.4

# tar -xf git-2.9.4.tar.gz

# make -j 20 prefix=/export/servers/git-2.9.4 all

# make prefix=/export/servers/git-2.9.4 install

c、配置git環境變量

### 在/etc/profile最後添加以下信息：

# vim /etc/profile

export GIT_HOME=/export/servers/git-2.9.4

export PATH=$GIT_HOME/bin:$PATH

6、安裝Maven

a、解壓及安裝

# cd /tmp/soft

# tar -xf apache-maven-3.5.0-bin.tar.gz

# mv apache-maven-3.5.0 maven-3.5.0

# mv maven-3.5.0 /export/servers/

b、配置環境變量

### 在/etc/profile中添加以下信息

# vim /etc/profile

export MAVEN_HOME=/export/servers/maven-3.5.0

export PATH=$PATH:$MAVEN_HOME/bin

7、安裝Ant

a、解壓及安裝

# tar xf apache-ant-1.10.1-bin.tar.gz

# mv apache-ant-1.10.1 ant-1.10.1

# mv ant-1.10.1 /export/servers/

b、配置環境變量

###在/etc/profile中添加以下信息

# vim /etc/profile

export ANT_HOME=/export/servers/ant-1.10.1

export PATH=$PATH:/export/servers/ant-1.10.1/bin

三、測試及啟動服務

1、測試JDK

# 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)

2、測試git

# git version

git version 2.9.4

3、測試maven

# mvn -v

Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-04T03:39:06+08:00)

Maven home: /export/servers/maven-3.5.0

Java version: 1.8.0_101, vendor: Oracle Corporation

Java home: /export/servers/jdk1.8.0_131/jre

Default locale: en_US, platform encoding: UTF-8

OS name: "linux", version: "2.6.32-642.el6.x86_64", arch: "amd64", family: "unix"

4、測試Tomcat和Jenkins

# cd /export/servers/tomcat-9.0.0.M21/bin

# /bin/sh startup.sh

# tailf ../logs/catalina.out

### 可以查看下日誌，看是否有Error的錯誤

5、添加開機自啟Tomcat

# echo "/bin/sh /export/servers/tomcat-9.0.0.M21/bin/startup.sh" >> /etc/rc.d/rc.local

四、Web登錄測試

1、先查看下Jenkins初始密碼

# cat /root/.jenkins/secret.key

4417e1e77b13aa560cfc05aaeb474cbf70f89fd9bc558e4963110c80d0a34d97

##### 復制此密碼，此密碼會在第一次打開Web頁面時使用，可能會遇到復制此密碼打不開，下面有解決方法

2、登錄Jenkins

打開瀏覽器----->在地址欄輸入：http://192.168.137.128:8080

此時，客戶端訪問頁面會提示404，看啟動日誌也是沒問題的，重新啟動Jenkins出現的問題如下：

Jun 21, 2017 2:17:44 PM hudson.model.UpdateCenter$DownloadJob run

SEVERE: Failed to install GitHub plugin

###解決方法

此錯誤是由於8080端口被占用，

改變端口再次執行，

java -jar jenkins.war --httpPort=$HTTP_PORT， 例如java -jar jenkins.war --httpPort=1088

啟動成功；

後打開瀏覽器，輸入http://192.168.137.128:1088，即可看到jenkins的頁面

###接下來還會出現Jenkins初始密碼不能使用，修改初始密碼為111111

建議備份在修改此文件

[[email protected] ~]# cd /root/.jenkins/users/admin/

[[email protected] admin]# ls

config.xml config.xml.ori

<hudson.security.HudsonPrivateSecurityRealm_-Details> <passwordHash>#jbcrypt:$2a$10$IVgY3xyUJajuUKp5wHWOUeoXxmDHk52.wYKZ4wz9Mt44O3i.V81Ry</passwordHash>

把<passwordHash>節點的內容（圖中紅色的那一串）換成#jbcrypt:$2a$10$DdaWzN64JgUtLdvxWIflcuQu2fgrrMSAMabF5TSrGK5nXitqK9ZMS

（註意前後有木有空格）

保存，重啟Jenkins程序。

然後輸入用戶名默認admin，密碼111111

到這進入Jenkins部署界面

至此，Jenkins的部署就已經完成，如有任何問題可以發郵件至：[email protected]
