docker项目——上线tomcat网站

项目：
　　1.使用docker部署tomcat环境
　　2.上线网站
　　3.完成访问使用等

第一步、启动基于tomcat镜像的容器

　　a、导入镜像

[root@localhost ~]# docker load < tomcat-app.tar 
[root@localhost ~]# docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
kubeguide/tomcat-app v1 a29e200a18e9 3 years ago 358MB
[root@localhost docker-image]# docker tag kubeguide/tomcat-app:v1 tomcat:latest #改名
[root@localhost docker-image]# docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
tomcat latest a29e200a18e9 3 years ago 358MB
b、启动tomcat镜像
[root@localhost docker-image]# docker run -d -p 8899:8080 tomcat
7e70f15807dadb6c15c2a40a9b494e69648b8706b038d27169e8faa9f131118c
[root@localhost docker-image]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
7e70f15807da tomcat "catalina.sh run" 8 seconds ago Up 7 seconds 0.0.0.0:8899->8080/tcp jovial_lehmann

第二步、清空容器tomcat网站根目录内容

　　a、进入容器

[root@localhost docker-image]# docker exec -it 7e70f15807da bash
root@7e70f15807da:/usr/local/tomcat# ls
LICENSE NOTICE RELEASE-NOTES RUNNING.txt bin conf include lib logs temp webapps work

　　b、切换至tomcat根目录

root@7e70f15807da:/usr/local/tomcat# cd webapps/
root@7e70f15807da:/usr/local/tomcat/webapps# ls
ROOT demo docs examples host-manager manager

　　c、删除ROOT下所有文件

root@7e70f15807da:/usr/local/tomcat/webapps# cd ROOT/
root@7e70f15807da:/usr/local/tomcat/webapps/ROOT# ls
RELEASE-NOTES.txt asf-logo-wide.gif bg-button.png bg-nav-item.png bg-upper.png favicon.ico tomcat-power.gif tomcat.gif tomcat.svg
WEB-INF asf-logo.png bg-middle.png bg-nav.png build.xml index.jsp tomcat.css tomcat.png
root@7e70f15807da:/usr/local/tomcat/webapps/ROOT# rm -rf *
root@7e70f15807da:/usr/local/tomcat/webapps/ROOT# ls
root@7e70f15807da:/usr/local/tomcat/webapps/ROOT#

第三步：复制网站文件至tomcat网站根目录并进入容器解压网站内容

[root@localhost /]# docker cp fuhai-jpress-alpha.zip 7e70f15807da:/usr/local/tomcat/webapps/ROOT
[root@localhost /]# docker exec -it 7e70f15807da bash
root@7e70f15807da:/usr/local/tomcat# cd /usr/local/tomcat/webapps/ROOT
root@7e70f15807da:/usr/local/tomcat/webapps/ROOT# ls
fuhai-jpress-alpha.zip
root@7e70f15807da:/usr/local/tomcat/webapps/ROOT# unzip fuhai-jpress-alpha.zip
root@7e70f15807da:/usr/local/tomcat/webapps/ROOT# ls
root@7e70f15807da:/usr/local/tomcat/webapps/ROOT# cd jpress/wars/
root@7e70f15807da:/usr/local/tomcat/webapps/ROOT/jpress/wars# cp jpress-web-newest.war ../../
root@7e70f15807da:/usr/local/tomcat/webapps/ROOT/jpress/wars# cd ../..
root@7e70f15807da:/usr/local/tomcat/webapps/ROOT# unzip jpress-web-newest.war
root@7e70f15807da:/usr/local/tomcat/webapps/ROOT# ls
META-INF WEB-INF fuhai-jpress-alpha.zip jpress jpress-web-newest.war robots.txt static templates

第四步：安装并配置数据库

[root@localhost yum.repos.d]# yum -y install MariaDB-server.x86_64
[root@localhost yum.repos.d]# systemctl restart mysql
[root@localhost yum.repos.d]# mysql
MariaDB [(none)]> create database tomcat;
MariaDB [(none)]> grant all privileges on *.* to tomcat@'%' identified by '123';
MariaDB [(none)]> exit

第五步：浏览器访问网站

第六步：重启docker_tomcat容器

[root@localhost yum.repos.d]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
7e70f15807da tomcat "catalina.sh run" 44 minutes ago Up 44 minutes 0.0.0.0:8899->8080/tcp jovial_lehmann
[root@localhost yum.repos.d]# docker restart 7e70f15807da
7e70f15807da
[root@localhost yum.repos.d]#
