一、創建Nginx Compose
1、創建DockerCompose項目目錄
mkdir compose_nginx_tomcat
cd compose_nginx_tomcat/
1.2、創建nginx管理目錄
mkdir nginx
cd nginx
1.3、將nginx源碼包下載到本地
- Nginx-1.12.1
- 下載地址：https://pan.baidu.com/s/1IAdODW63jbpwbQX992coYg
- 密碼：p89j
1.4、創建Dockerfile文件
vim Dockerfile
# 指定鏡像 FROM centos:6 # 指定管理員 MAINTAINER xiangsikai # 執行命令安裝編譯庫文件 RUN yum install -y gcc gcc-c++ make openssl-devel pcre-devel # 添加解壓nginx包到/tmp目錄下 ADD nginx-1.12.1.tar.gz /tmp # 進入目錄進行編譯安裝 RUN cd /tmp/nginx-1.12.1 && ./configure --prefix=/usr/local/nginx && make -j 2 && make install# 刪除容器內置配置文件 RUN rm -f /usr/local/nginx/conf/nginx.conf # 復制本地配置文件到容器內 COPY nginx.conf /usr/local/nginx/conf # 聲明暴露端口 EXPOSE 80 # 啟動容器Nginx服務，指定全局命令daemon off保證服務在前臺運行不會關閉 CMD ["/usr/local/nginx/sbin/nginx", "-g", "daemon off;"]
1.5、創建nginx.conf配置文件
vim nginx.conf
user root; worker_processes auto; error_log logs/error.log info; pid logs/nginx.pid; events { use epoll; } http { include mime.types; default_type application/octet-stream; log_format main ‘$upstream_addr $remote_addr - $remote_user [$time_local] "$request" ‘ ‘$status $body_bytes_sent "$http_referer" ‘ ‘"$http_user_agent" "$http_x_forwarded_for"‘; access_log logs/access.log main; sendfile on; keepalive_timeout 65; # 代理三臺tomcat服務 upstream www.example.com { #ip_hash; server tomcat01:8080; server tomcat02:8080; server tomcat03:8080; } # 動靜分離 server { listen 80; server_name localhost; # 動態請求轉發給tomcat處理 location / { proxy_pass http://www.example.com; } # 靜態資源請求交給nginx處理 location ~ \.(html|css|js|jpg|png|gif)$ { root /opt/webapps/ROOT; } } }nginx配置文件
二、創建Mysql Compose
2.1、創建Mysql管理目錄
mkdir mysql
cd mysql
mkdir conf
cd conf
2.2、創建mysql配置文件
vim my.cnf
[mysqld] user=mysql port=3306 datadir=/var/lib/mysql socket=/var/run/mysqld/mysqld.sock pid-file=/var/run/mysqld/mysqld.pid log_error=/var/log/mysql/error.log character_set_server = utf8 max_connections=3600mysql配置文件
三、創建Tomcat Compose
3.1、創建tomcat管理目錄與網站目錄
mkdir tomcat mkdir -p webapps/ROOT/ cd tomcat
3.2、下載tomcat、jdk 壓縮文件下載到本地
- apache-tomcat-8.0.46
- 下載地址：https://pan.baidu.com/s/1MuSGn3S1wILUfKZmemUu8g
- 密碼：xydu
- jdk-8u181-linux-x64
- 下載地址：https://pan.baidu.com/s/1eJPPR1cun09u4Uks0800hg
- 密碼：gjvv
3.3 創建Dockerfile文件
vim Dockerfile
# 指定鏡像 FROM centos:6 # 指定管理員 MAINTAINER xiangsikai # 解壓jdk包到指定目錄 ADD jdk-8u181-linux-x64.tar.gz /usr/local # 安裝jdk包到指定目錄 ENV JAVA_HOME /usr/local/jdk1.8.0_181 # 解壓tomcat包到指定目錄 ADD apache-tomcat-8.0.46.tar.gz /usr/local # 將本地配置文件復制到鏡像內 COPY server.xml /usr/local/apache-tomcat-8.0.46/conf # 指定服務暴露端口 EXPOSE 8080 # 啟動tomcat服務 ENTRYPOINT ["/usr/local/apache-tomcat-8.0.46/bin/catalina.sh", "run"]
3.4 創建server.xml配置文件
vim server.xml

四、創建docker-compose.yml
4.1、在compose_nginx_tomcat目錄下創建docker-compose.yml
vim docker-compose.yml
# 指定服務版本號 version: ‘3‘ # 服務 services: # 服務名稱 nginx: # 指定服務容器名字 hostname: nginx # 構建 build: # 指定目錄上下文構建鏡像 context: ./nginx # 指定dockerfile文件名稱 dockerfile: Dockerfile # 映射數組級的端口 ports: - 80:80 # 映射服務別名 links: - tomcat01:tomcat01 - tomcat02:tomcat02 - tomcat03:tomcat03 # 映射服務數據卷路徑 volumes: - ./webapps:/opt/webapps # 啟動依賴，按順序啟動服務 depends_on: - mysql - tomcat01 - tomcat02 - tomcat03 # 服務名稱 tomcat01: # 指定服務容器名字 hostname: tomcat01 # 指定目錄上下文構建鏡像 build: ./tomcat # 映射服務別名 links: - mysql:mysql-db # 映射服務數據卷路徑 volumes: - ./webapps:/usr/local/apache-tomcat-8.0.46/webapps # 服務名稱 tomcat02: # 指定服務容器名字 hostname: tomcat02 # 指定目錄上下文構建鏡像 build: ./tomcat # 映射服務別名 links: - mysql:mysql-db # 映射服務數據卷路徑 volumes: - ./webapps:/usr/local/apache-tomcat-8.0.46/webapps # 服務名稱 tomcat03: # 指定服務容器名字 hostname: tomcat03 # 指定目錄上下文構建鏡像 build: ./tomcat # 映射服務別名 links: - mysql:mysql-db # 映射服務數據卷路徑 volumes: - ./webapps:/usr/local/apache-tomcat-8.0.46/webapps # 服務名稱 mysql: # 指定服務容器名字 hostname: mysql # 指定服務容器名字 image: mysql:5.6 # 映射數組級的端口 ports: - 3306:3306 # 映射服務數據卷路徑 volumes: - ./mysql/conf:/etc/mysql/conf.d - ./mysql/data:/var/lib/mysql # 指定數據庫變量 environment: # 設置數據庫密碼 MYSQL_ROOT_PASSWORD: 123456 # 添加user用戶 MYSQL_USER: user # 設置user用戶密碼 MYSQL_PASSWORD: user123
4.2、編寫測試頁面
vim webapps/ROOT/index.jsp
java ...........
4.3、執行dockerCompose 一鍵部署Nginx代理Tomcat集群
# 管理目錄下compose_nginx_tomcat 執行該命令 -d 後臺運行 docker-compose up -d
五、測試容器服務
5.1、查看啟動狀態終端輸出
Creating compose_nginx_tomcat_mysql_1 ... done
Creating compose_nginx_tomcat_tomcat03_1 ... done
Creating compose_nginx_tomcat_tomcat02_1 ... done
Creating compose_nginx_tomcat_tomcat01_1 ... done
Creating compose_nginx_tomcat_nginx_1 ... done
5.2、查看後臺運行容器
docker-compose ps
Name Command State Ports ------------------------------------------------------------------------ compose_nginx_tomcat docker- Up 0.0.0.0:3306->3306/ _mysql_1 entrypoint.sh tcp mysqld compose_nginx_tomcat /usr/local/nginx/sb Up 0.0.0.0:80->80/tcp _nginx_1 in/ngin ... compose_nginx_tomcat /usr/local/apache- Up 8080/tcp _tomcat01_1 tomcat-8 ... compose_nginx_tomcat /usr/local/apache- Up 8080/tcp _tomcat02_1 tomcat-8 ... compose_nginx_tomcat /usr/local/apache- Up 8080/tcp _tomcat03_1 tomcat-8 ...
5.3、測試數據庫
# 1、進入數據庫容器 docker container exec -it c764f337ffad /bin/bash # 2、進入數據庫 mysql -h192.168.1.77 -uroot -p123456 # 3、查看創建用戶user mysql> select user,host from mysql.user; +------+-----------+ | user | host | +------+-----------+ | root | % | | user | % | | root | localhost | +------+-----------+ 3 rows in set (0.00 sec)
5.4、瀏覽器測試nginx代理tomcat
# 1、進入nginx管理界面 docker container exec -it c764f337ffad /bin/bash # 2、查看輸出日誌測試輪詢代理 [root@nginx /]# tail /usr/local/nginx/logs/access.log -f
