一、创建Nginx Compose
1、创建DockerCompose项目目录
1mkdir compose_nginx_tomcat 2cd compose_nginx_tomcat/
1.2、创建nginx管理目录
1mkdir nginx 2cd nginx
1.3、将nginx源码包下载到本地
- Nginx-1.12.1
- 下载地址：https://pan.baidu.com/s/1IAdODW63jbpwbQX992coYg
- 密码：p89j
1.4、创建Dockerfile文件
vim Dockerfile
1# 指定镜像 2FROM centos:6 3# 指定管理员 4MAINTAINER xiangsikai 5# 执行命令安装编译库文件 6RUN yum install -y gcc gcc-c++ make openssl-devel pcre-devel 7# 添加解压nginx包到/tmp目录下 8ADD nginx-1.12.1.tar.gz /tmp 9# 进入目录进行编译安装 10RUN cd /tmp/nginx-1.12.1 && ./configure --prefix=/usr/local/nginx && make -j 2 && make install 11# 删除容器内置配置文件 12RUN rm -f /usr/local/nginx/conf/nginx.conf 13# 复制本地配置文件到容器内 14COPY nginx.conf /usr/local/nginx/conf 15# 声明暴露端口 16EXPOSE 80 17# 启动容器Nginx服务，指定全局命令daemon off保证服务在前台运行不会关闭 18CMD ["/usr/local/nginx/sbin/nginx", "-g", "daemon off;"]
1.5、创建nginx.conf配置文件
vim nginx.conf
1user root; 2worker_processes auto; 3 4error_log logs/error.log info; 5 6pid logs/nginx.pid; 7 8 9events { 10 use epoll; 11} 12 13http { 14 15 include mime.types; 16 default_type application/octet-stream; 17 18 log_format main '$upstream_addr $remote_addr - $remote_user [$time_local] "$request" ' 19 '$status $body_bytes_sent "$http_referer" ' 20 '"$http_user_agent" "$http_x_forwarded_for"'; 21 22 access_log logs/access.log main; 23 sendfile on; 24 keepalive_timeout 65; 25 26# 代理三台tomcat服务 27 upstream www.example.com { 28 #ip_hash; 29 server tomcat01:8080; 30 server tomcat02:8080; 31 server tomcat03:8080; 32 } 33 34# 动静分离 35 server { 36 listen 80; 37 server_name localhost; 38 39# 动态请求转发给tomcat处理 40 location / { 41 proxy_pass http://www.example.com; 42 } 43# 静态资源请求交给nginx处理 44 location ~ \.(html|css|js|jpg|png|gif)$ { 45 root /opt/webapps/ROOT; 46 } 47 } 48}

mysql配置文件
三、创建Tomcat Compose
3.1、创建tomcat管理目录与网站目录
1mkdir tomcat 2mkdir -p webapps/ROOT/ 3cd tomcat
3.2、下载tomcat、jdk 压缩文件下载到本地
-
apache-tomcat-8.0.46
-

tomcat配置文件
四、创建docker-compose.yml
4.1、在compose_nginx_tomcat目录下创建docker-compose.yml
vim docker-compose.yml
1# 指定服务版本号 2version: '3' 3# 服务 4services: 5# 服务名称 6 nginx: 7# 指定服务容器名字 8 hostname: nginx 9# 构建 10 build: 11# 指定目录上下文构建镜像 12 context: ./nginx 13# 指定dockerfile文件名称 14 dockerfile: Dockerfile 15# 映射数组级的端口 16 ports: 17 - 80:80 18# 映射服务别名 19 links: 20 - tomcat01:tomcat01 21 - tomcat02:tomcat02 22 - tomcat03:tomcat03 23# 映射服务数据卷路径 24 volumes: 25 - ./webapps:/opt/webapps 26# 启动依赖，按顺序启动服务 27 depends_on: 28 - mysql 29 - tomcat01 30 - tomcat02 31 - tomcat03 32 33# 服务名称 34 tomcat01: 35# 指定服务容器名字 36 hostname: tomcat01 37# 指定目录上下文构建镜像 38 build: ./tomcat 39# 映射服务别名 40 links: 41 - mysql:mysql-db 42# 映射服务数据卷路径 43 volumes: 44 - ./webapps:/usr/local/apache-tomcat-8.0.46/webapps 45 46# 服务名称 47 tomcat02: 48# 指定服务容器名字 49 hostname: tomcat02 50# 指定目录上下文构建镜像 51 build: ./tomcat 52# 映射服务别名 53 links: 54 - mysql:mysql-db 55# 映射服务数据卷路径 56 volumes: 57 - ./webapps:/usr/local/apache-tomcat-8.0.46/webapps 58 59# 服务名称 60 tomcat03: 61# 指定服务容器名字 62 hostname: tomcat03 63# 指定目录上下文构建镜像 64 build: ./tomcat 65# 映射服务别名 66 links: 67 - mysql:mysql-db 68# 映射服务数据卷路径 69 volumes: 70 - ./webapps:/usr/local/apache-tomcat-8.0.46/webapps 71 72# 服务名称 73 mysql: 74# 指定服务容器名字 75 hostname: mysql 76# 指定服务容器名字 77 image: mysql:5.6 78# 映射数组级的端口 79 ports: 80 - 3306:3306 81# 映射服务数据卷路径 82 volumes: 83 - ./mysql/conf:/etc/mysql/conf.d 84 - ./mysql/data:/var/lib/mysql 85# 指定数据库变量 86 environment: 87# 设置数据库密码 88 MYSQL_ROOT_PASSWORD: 123456 89# 添加user用户 90 MYSQL_USER: user 91# 设置user用户密码 92 MYSQL_PASSWORD: user123
4.2、编写测试页面
vim webapps/ROOT/index.jsp
java ...........
4.3、执行dockerCompose 一键部署Nginx代理Tomcat集群
1# 管理目录下compose_nginx_tomcat 执行该命令 -d 后台运行 2docker-compose up -d
五、测试容器服务
5.1、查看启动状态终端输出****
1Creating compose_nginx_tomcat_mysql_1 ... done 2Creating compose_nginx_tomcat_tomcat03_1 ... done 3Creating compose_nginx_tomcat_tomcat02_1 ... done 4Creating compose_nginx_tomcat_tomcat01_1 ... done 5Creating compose_nginx_tomcat_nginx_1 ... done
5.2、查看后台运行容器
1docker-compose ps 2 3 Name Command State Ports 4------------------------------------------------------------------------ 5compose_nginx_tomcat docker- Up 0.0.0.0:3306->3306/ 6_mysql_1 entrypoint.sh tcp 7 mysqld 8compose_nginx_tomcat /usr/local/nginx/sb Up 0.0.0.0:80->80/tcp 9_nginx_1 in/ngin ... 10compose_nginx_tomcat /usr/local/apache- Up 8080/tcp 11_tomcat01_1 tomcat-8 ... 12compose_nginx_tomcat /usr/local/apache- Up 8080/tcp 13_tomcat02_1 tomcat-8 ... 14compose_nginx_tomcat /usr/local/apache- Up 8080/tcp 15_tomcat03_1 tomcat-8 ...
5.3、测试数据库
1# 1、进入数据库容器 2docker container exec -it c764f337ffad /bin/bash 3 4# 2、进入数据库 5mysql -h192.168.1.77 -uroot -p123456 6 7# 3、查看创建用户user 8mysql> select user,host from mysql.user; 9 10+------+-----------+ 11| user | host | 12+------+-----------+ 13| root | % | 14| user | % | 15| root | localhost | 16+------+-----------+ 173 rows in set (0.00 sec)
5.4、浏览器测试nginx代理tomcat
1# 1、进入nginx管理界面 2docker container exec -it c764f337ffad /bin/bash 3 4# 2、查看输出日志测试轮询代理 5[root@nginx /]# tail /usr/local/nginx/logs/access.log -f 6 7172.20.0.4:8080 192.168.1.2 - - [25/Oct/2018:07:34:07 +0000] "GET / HTTP/1.1" 200 10 "-" "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:62.0) Gecko/20100101 Firefox/62.0" "-" 8172.20.0.3:8080 192.168.1.2 - - [25/Oct/2018:07:34:07 +0000] "GET /favicon.ico HTTP/1.1" 404 1016 "-" "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:62.0) Gecko/20100101 Firefox/62.0" "-" 9172.20.0.5:8080 192.168.1.2 - - [25/Oct/2018:07:34:31 +0000] "GET / HTTP/1.1" 200 10 "-" "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:62.0) Gecko/20100101 Firefox/62.0" "-" 10172.20.0.4:8080 192.168.1.2 - - [25/Oct/2018:07:34:35 +0000] "GET / HTTP/1.1" 200 10 "-" "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:62.0) Gecko/20100101 Firefox/62.0" "-" 11172.20.0.3:8080 192.168.1.2 - - [25/Oct/2018:07:34:40 +0000] "GET / HTTP/1.1" 200 10 "-" "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:62.0) Gecko/20100101 Firefox/62.0" "-" 12172.20.0.5:8080 192.168.1.2 - - [25/Oct/2018:07:34:41 +0000] "GET / HTTP/1.1" 200 10 "-" "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:62.0) Gecko/20100101 Firefox/62.0" "-"
