jenkins学习

下载tomcat

jenkins是一个Java程序，故，最好的办法是安装tomcat,在安装jenkins

# mkdir -p /soft
# cd /soft/
下载tomcat
# wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.32/bin/apache-tomcat-8.5.32.tar.gz
# tar xf apache-tomcat-8.5.32.tar.gz

移动tomcat到/usr/local下
# mv apache-tomcat-8.5.32 /usr/local/
建立软连接
# ln -s /usr/local/apache-tomcat-8.5.32 /usr/local/tomcat
查看建立的连接
# ls -l /usr/local | grep "tomcat"
drwxr-xr-x. 9 root root 4096 Aug  7 12:05 apache-tomcat-8.5.32
lrwxrwxrwx. 1 root root   31 Aug  7 12:06 tomcat -> /usr/local/apache-tomcat-8.5.32

#下载jdk
# yum install java-1.8.0-openjdk.x86_64 java-1.8.0-openjdk-devel.x86_64 -y
# cd /usr/local/tomcat/bin/
执行tomcat
# ./startup.sh
#查看端口是否打开
# netstat -tulnp | grep 8080
tcp        0      0 :::8080                     :::*                        LISTEN      2380/java           
# 

#测试是否OK
# curl  127.0.0.1:8080 -I

部署jenkins

#下载jenkins的war包
# wget http://mirrors.jenkins.io/war-stable/latest/jenkins.war

#清空tomcat的www root目录
# rm -rf /usr/local/tomcat/webapps/ROOT/*

#移动jenkins至tomcat中
# mv jenkins.war /usr/local/tomcat/webapps/ROOT/
# cd /usr/local/tomcat/webapps/ROOT/
# ls
jenkins.war
# unzip jenkins.war 
-bash: unzip: command not found
#安装unzip并且解压war安装包
# yum install unzip -y && unzip jenkins.war

浏览网页是这样的，从服务器获取key,输入下方之后进行安装

# cat /root/.jenkins/secrets/initialAdminPassword
f2a10613c5f04e789ad944f96c7a615a
#

接着下一步下一步，配置用户名和密码，至此，jenkins安装完成

使用jenkins配置第一个项目

背景: 在jenkins机器上，有一个c文件，想通过jenkins去自动编译该文件，内容如下:

路径:
# pwd
/root/c

文件夹内容
# ls
Jenkins_Test.c

#查看这个c程序，其实就是调用print_hello函数，输出一个Hello World
# cat Jenkins_Test.c 
    # include <stdio.h>

    void print_hello() {
        printf ("Hello World\n");
    }

    int main() {
        print_hello();
        return 0;
    }
#
