gitlab之实战部署

#：准备Java环境，安装jdk
root@ubuntu:~# cd /usr/local/src/
root@ubuntu:/usr/local/src# ls
jdk-8u191-linux-x64.tar.gz
root@ubuntu:/usr/local# ln -sv /usr/local/src/jdk1.8.0_191 /usr/local/jdk

#:配置环境变量
root@ubuntu:/data/tomcat# vim /etc/profile
export JAVA_HOME=/usr/local/jdk
export TOMCAT_HOME=/apps/tomcat
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$TOMCAT_HOME/bin:$PATH
export CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar

#：创建目录，并下载Tomcat
root@ubuntu:/data/tomcat# mkdir /apps
root@ubuntu:/data/tomcat# cd /apps/
root@ubuntu:/data/tomcat# wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.46/bin/apache-tomcat-8.5.46.tar.gz
root@ubuntu:/data/tomcat# tar xf apache-tomcat-8.5.46.tar.gz
root@ubuntu:/data/tomcat# ln -sv /apps/apache-tomcat-8.5.46 /apps/tomcat
root@ubuntu:/data/tomcat# cd tomcat

#:修改Tomcat配置文件
root@ubuntu:/data/tomcat# vim conf/server.xml 
 <Host name="localhost"  appBase="/data/tomcat/tomcat_webapps" unpackWARs="true" autoDeploy="true">

#：创建三个目录（appdir放压缩文件，webdir放解压文件，webapps是Tomcat的访问/目录）
root@ubuntu:/data/tomcat# mkdir /data/tomcat/{tomcat_appdir,tomcat_webdir,tomcat_webapps} -pv

#：创建一个Tomcat用户（必须使其可以登录）
root@ubuntu:/data/tomcat# groupadd -g 2019 tomcat
root@ubuntu:/data/tomcat# useradd -m -u 2019 -s /bin/bash -g tomcat tomcat

#：编辑一个Tomcat的启动停止脚本
root@ubuntu:~# vim tomcat
#!/bin/bash

#：切换到tomcat,利用脚本启动服务

#:查找keepalive的配置文件在哪里
root@ubuntu:~# find / -name keepalived*.conf*

#：将配置文件拷贝到、etc目录
root@ubuntu:~# cp /usr/share/doc/keepalived/samples/keepalived.conf.vrrp /etc/keepalived/keepalived.conf

#：修改配置文件
root@ubuntu:~# vim /etc/keepalived/keepalived.conf

#：修改内核参数

root@ubuntu:~# vim /etc/sysctl.conf
net.ipv4.ip_nonlocal_bind = 1
net.ipv4.ip_forward = 1

#：重启服务
root@ubuntu:~# systemctl restart haproxy keepalived

#:在jenkins服务器，将公钥拷贝到Tomcat服务器
root@ubuntu:/opt/web1# ssh-copy-id tomcat@192.168.6.104

#:怎样部署war包的jenkins

#:先部署jdk
root@ubuntu:~# cd /usr/local/src/
root@ubuntu:/usr/local/src# tar xf jdk-8u191-linux-x64.tar.gz 
root@ubuntu:/usr/local/src# ln -sv /usr/local/src/jdk
jdk1.8.0_191/               jdk-8u191-linux-x64.tar.gz  
root@ubuntu:/usr/local/src# ln -sv /usr/local/src/jdk1.8.0_191 /usr/local/jdk

#：配置环境变量

root@ubuntu:/usr/local/src# vim /etc/profile
export JAVA_HOME=/usr/local/jdk
export TOMCAT_HOME=/apps/tomcat
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$TOMCAT_HOME/bin:$PATH
export CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar
root@ubuntu:/usr/local/src# source /etc/profile

#：下载war包

root@ubuntu:/usr/local/src# mkdir /data/jenkins -pv
root@ubuntu:/usr/local/src# cd /data/jenkins/

#：启动服务
root@ubuntu:/data/jenkins# java -jar jenkins.war 

#：

#基于Tomcat装jenkins的war包
#：先将业务停掉
root@ubuntu:/data/tomcat/tomcat_webapps# /etc/init.d/tomcat stop

#：准备war包
root@ubuntu:/data/tomcat/tomcat_webapps# ls
jenkins.war

#：解压

root@ubuntu:/data/tomcat/tomcat_webapps# unzip jenkins.war -d jenkins
root@ubuntu:/data/tomcat/tomcat_webapps# chown -R  tomcat.tomcat /data/tomcat/

#：切换到Tomcat启动服务
root@ubuntu:/data/tomcat/tomcat_webapps# su - tomcat
tomcat@ubuntu:~$ /etc/init.d/tomcat start

#：直接测试访问会出错，安装一下包
root@ubuntu:/data/tomcat/tomcat_webapps# apt-get install libxrender-dev
root@ubuntu:/data/tomcat/tomcat_webapps# apt-get install libxtst-dev
