java项目代码上线架构图

ip地址及主机名规划

10.0.0.11 deploy
10.0.0.12 tomcat-web01
10.0.0.13 git.oldboyedu.com

2：部署gitlab服务器并上传代码

wget https://mirror.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-11.4.5-ce.0.el7.x86_64.rpm

yum localinstall gitlab-ce-11.4.5-ce.0.el7.x86_64.rpm -y

vim /etc/gitlab/gitlab.rb

external_url 'http://git.oldboyedu.com'

gitlab-ctl reconfigure

上传项目代码到gitlab

rz jeesns.tar.gz

tar xf jeesns.tar.gz

cd jeesns/

rm -fr .git*

git init

git remote add origin http://git.oldboyedu.com/root/jeesns.git

git add *

git commit -m '初始提交'

git push -u origin master

3:部署tomcat服务器和数据库

rz jdk-8u102-linux-x64.rpm

rz apache-tomcat-8.0.27.tar.gz

rpm -ivh jdk-8u102-linux-x64.rpm

mkdir /application/

tar zvxf apache-tomcat-8.0.27.tar.gz -C /application/

mv /application/apache-tomcat-8.0.27 /application/tomcat

#tomcat启动加速的方法

vim /usr/java/jdk1.8.0_102/jre/lib/security/java.security

修改117行为：securerandom.source=file:/dev/urandom

/application/tomcat/bin/startup.sh

为项目准备好数据库jeesns，设置数据库root用户密码为root

yum install  mariadb-server -y

mysql_secure_installation

mysqladmin -uroot password 'root'

mysql -uroot -proot -e 'create database jeesns;'

4：安装maven

rz jdk-8u102-linux-x64.rpm

rpm -ivh jdk-8u102-linux-x64.rpm

wget https://mirror.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.6.0/binaries/apache-maven-3.6.0-bin.tar.gz

tar xf apache-maven-3.6.0-bin.tar.gz

mv apache-maven-3.6.0 /usr/local/

ln -s /usr/local/apache-maven-3.6.0 /usr/local/maven

vim /etc/profile

export M2_HOME=/usr/local/maven

export PATH=${M2_HOME}/bin:$PATH

source /etc/profile

mvn -v

5：编译和部署（上线）

a：代码拉取

#需要在gitlab中添加密钥对

git clone git@git.oldboyedu.com:root/jeesns.git

b：编译项目代码

cd jeesns/

mvn clean package

c：数据库升级

yum install sshpass -y

sshpass -p123456 scp /opt/jeesns/jeesns-web/database/jeesns.sql root@10.0.0.12:/tmp

sshpass -p123456 ssh root@10.0.0.12 'mysql -uroot -proot jeesns </tmp/jeesns.sql'

d：远程推送war包

sshpass -p123456 ssh root@10.0.0.12 'mv /application/tomcat/webapps/* /opt'

sshpass -p123456 scp -rp /opt/jeesns/jeesns-web/target/jeesns-web.war 10.0.0.12:/application/tomcat/webapps/ROOT.war

测试访问：

把上面的第五步（编译和部署）用shell脚本来实现，这个脚本就是shell自动化上线脚本

把上面的第五步用jenkins来实现，即jenkins+gitlab代码自动上线。
