安装部署jenkins [六]

参数化构建

必要的时候并发构建

在足够的节点下

[root@linux-node1 workspace]# pwd
/root/jenkins_home/workspace
[root@linux-node1 workspace]# ll
total 8
drwxr-xr-x 9 root root 4096 Dec  8 16:42 my-freestyle-job
drwxr-xr-x 9 root root 4096 Dec  8 17:42 my-freestyle-job@2    有两个并发，注意工作目录的情况，不要让垃圾信息占用磁盘空间信息
drwxr-xr-x 2 root root    6 Dec  8 17:42 my-freestyle-job@2@tmp
drwxr-xr-x 2 root root    6 Dec  8 17:43 my-freestyle-job@tmp

如何限制并发数

安装Throttle Concurrent Builds Plugin插件

自动触发构建

常用的Triggers

Build periodically 设定类似Cron周期性时间触发构建

Poll SCM 设定类似Cron周期性时间触发检查代码变化，只有当代码发生变动时才触发构建

Hooks Gitlab hooks、GitHub hooks

Evens Gerrit evnets

归档

归档的Artfacts会存储在Master上的Jenkins home目录下

存储、网络、IO读写等压力（构建在slave，构建中拷贝到master，配合历史构建清理设置）

不适合归档大的Artifact

在shell配置的环境变量Jenkins是不认识环境变量。

[root@linux-node1 ~]# mkdir -pv mvn
[root@linux-node1 ~]# cd mvn
[root@linux-node1 mvn]# wget http://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.5.2/binaries/apache-maven-3.5.2-bin.tar.gz
[root@linux-node1 mvn]# tar xf apache-maven-3.5.2-bin.tar.gz 
[root@linux-node1 mvn]# export PATH=/root/mvn/apache-maven-3.5.2/bin:$PATH
[root@linux-node1 mvn]# cd apache-maven-3.5.2/
[root@linux-node1 apache-maven-3.5.2]# ls
bin  boot  conf  lib  LICENSE  NOTICE  README.txt
[root@linux-node1 apache-maven-3.5.2]# cd bin/
[root@linux-node1 bin]#

[root@linux-node1 bin]# tail -1 /etc/profile
export PATH=/root/mvn/apache-maven-3.5.2/bin:$PATH

参数化构建

有如下报错，解决思路

提示已存在

[root@linux-node1 my-freestyle-job]# pwd
/root/jenkins_home/workspace/my-freestyle-job
[root@linux-node1 my-freestyle-job]# mvn package
......
....
-------------------------------------------------------
 T E S T S
-------------------------------------------------------
Running com.juvenxu.mvnbook.account.email.AccountEmailServiceTest
Exception in thread "Thread-0" java.lang.RuntimeException: java.net.BindException: Address already in use (Bind failed)

[root@linux-node1 my-freestyle-job]# systemctl stop postfix.service 邮件服务器的问题，停止。

到节点上的workspace项目下mvn package查看

停止后在次查看 mvn package 成功

结构化构建clean、compile、package

归档artifacts

[root@linux-node1 my-freestyle-job]# pwd
/root/jenkins_home/workspace/my-freestyle-job
[root@linux-node1 my-freestyle-job]# find . -name *.jar
