jeesns项目代码自动上线
经过上一次失败的教训，这一次通过学习了maven项目管理工具，肯定能部署成功的。失败案例jeesns项目上线（失败案例），这对java项目的部署是一次很好的学习
Jenkins上的操作
新建一个项目，类型选maven
源码管理里获取git，gitlab上的项目地址（偷笑，这里偷了贪，图片用的大转盘项目的，哈哈）
配置密钥
配置一下，这里提示找不到maven的路径。因为我们maven是手动安装的， 不是jenkins自动安装，需要指定一下maven所在的路径
解决这问题方法：
在选全局配置选项
找到maven选项，取消自动安装
进行指定maven，安装路径
再看看问题已经解决了
手动打包就成功
但用Jenkins自动打包就不行了，报错

卡住了，这个问题有待解决....
我怎么排查都不知道到底是哪里错了，已经好多天了，就在一筹莫展之时，难道是软件代码本身的问题？，然后我去下载了，jeesns_v1.3版本的，把原先的那个1.4从远程仓库删除，发现正常了，我真是个机灵鬼
jenkins虐我千百遍，我带它如...rz，哼哼，来来来，继续肝，肝起来
Tomcat服务器上操作
部署tomcat和数据库
这里我只需要部署tomcat，mysql我已经提前部署好了
[root@kk tools]# tar xf apache-tomcat-8.5.50.tar.gz [root@kk tools]# ln -s apache-tomcat-8.5.50 tomcat
还需要安装jdk，因为我以前安装过jdk，要找jdk的默认安装路径方法:
首先是确认是否安装JDK
[root@kk tools]# java -cersion
Unrecognized option: -cersion
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
然后查找java命令的位置
[root@kk tools]# which java
/usr/bin/java
查找java命令的位置所对于的软链地址
[root@kk tools]# ls -l /usr/bin/java
lrwxrwxrwx. 1 root root 22 Sep 3 08:23 /usr/bin/java -> /etc/alternatives/java
最后通过软链地址查找JDK的安装目录
[root@kk tools]# ls -l /etc/alternatives/java
lrwxrwxrwx. 1 root root 72 Sep 3 08:23 /etc/alternatives/java -> /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.131-11.b12.el7.x86_64/jre/bin/java修改文件
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.131-11.b12.el7.x86_64/jre/lib/security/java.security
[root@kk tools]# vim /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.131-11.b12.el7.x86_64/jre/lib/security/java.security在117行，修改
securerandom.source=file:/dev/urandom
启动tomcat
[root@kk tools]# sh tomcat/bin/startup.sh
Using CATALINA_BASE: /server/tools/tomcat
Using CATALINA_HOME: /server/tools/tomcat
Using CATALINA_TMPDIR: /server/tools/tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /server/tools/tomcat/bin/bootstrap.jar:/server/tools/tomcat/bin/tomcat-juli.jar
Tomcat started.
创建jeesns的数据库
下载安装过程就不写了，不会的请看一下编译安装MySQL
mysql> create database jeesns; Query OK, 1 row affected (0.03 sec) mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | jeesns | | mysql | | performance_schema | | sys | +--------------------+ 5 rows in set (0.03 sec)
将jeesns的数据库表导入数据库
这里你去jeenkins上把表发过来，或者用rsync把表拉去过来
因为jeesns项目在gitlab仓库上由jenkins持续集成工具拉去到本地192.168.5.31服务器上，jeesnsn项目的数据表要先传到tomcat服务器，tomcat服务器IP192.168.5.41，才能导入数据库
/var/lib/jenkins/workspace/jeesns-job/jeesns-web/database
[root@nfs01 database]# pwd /var/lib/jenkins/workspace/jeesns-job/jeesns-web/database [root@nfs01 database]# ll total 40 -rwxr-xr-x 1 jenkins jenkins 28667 Mar 3 15:16 jeesns.sql -rw-r--r-- 1 jenkins jenkins 3491 Mar 3 15:16 update_1.2.0to1.2.1.sql -rw-r--r-- 1 jenkins jenkins 1026 Mar 3 15:16 update_1.2.1to1.3.sql -rw-r--r-- 1 jenkins jenkins 1344 Mar 3 15:16 update_1.3to1.3.1.sql
[root@nfs01 database]# rsync -avz jeesns.sql root@192.168.5.41:/server/tools/
sending incremental file list
jeesns.sql
sent 5711 bytes received 31 bytes 11484.00 bytes/sec
total size is 28667 speedup is 4.99去192.168.5.41服务器上确认一下
[root@backup ~]# cd /server/tools/
[root@backup tools]# ll
total 507540
drwxr-xr-x 9 root root 220 Mar 3 17:17 apache-tomcat-8.5.50
-rwxr-xr-x 1 665 665 28667 Mar 3 15:16 jeesns.sql把jeesns.sql进行导入数据库
[root@backup tools]# mysql -uroot -pHe30772818. jeesns < /server/tools/jeesns.sql
mysql: [Warning] Using a password on the command line interface can be insecure.查看是否导入成功
[root@backup tools]# mysql -uroot -pHe30772818. -e "use jeesns;show tables"
mysql: [Warning] Using a password on the command line interface can be insecure.

编写Shell脚本
这个脚本编写好，放在jenkins服务器上
[root@nfs01 scripts]# vim jeesns.sh
#!/bin/bash
Tomcat_IP=192.168.5.41
Tomcat_Dir=/server/tools/tomcat/webapps
Jeesns_war=/var/lib/jenkins/workspace/jeesns-job/jeesns-web/target/jeesns-web.war
TIME=`date +%F-%H-%M-%S`
ssh root@$Tomcat_IP "cp -a ${Tomcat_Dir}/ROOT.war /opt/ROOT-${TIME}.war"
ssh root@$Tomcat_IP "rm -rf ${Tomcat_Dir}/*"
scp -rp $Jeesns_war ${Tomcat_IP}:${Tomcat_Dir}/ROOT.war
回到jeekins上操作
在jeesns-job项目里添加构建，具体细节请对照文章Jenkins+Gitlab+Shell脚本 实现手动代码上线
保存后，点立即构建，先用手动的方式，检查是否成功
成功了，非常好，手动部署代码上线，已经完成，现在配置自动上线
自动上线
这里要是看不懂，可以看一下文章Jenkins+Gitlab 实现代码自动化上线
在jenkins上jeesns-job项目中添加触发器
把这个令牌保存下来，去gitlab上进行一一关联
最好进行测试，查看测试结构，验证我就不严重了，可以参考推荐的文章
终于成功了，不容易，不容易，不容易
