7 directories, 10 files

1、建立Nginx Composejava

一、建立DockerCompose項目目錄mysql

mkdir compose_nginx_tomcat
cd compose_nginx_tomcat/

1.二、建立nginx管理目錄linux

mkdir nginx
cd nginx

1.三、將nginx源碼包下載到本地nginx

Nginx-1.12.1
下載地址：https://pan.baidu.com/s/1IAdODW63jbpwbQX992coYg
密碼：p89j

1.四、建立Dockerfile文件c++

vim Dockerfileweb

# 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 
# 複製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
# 啓動容器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;"]

1.五、建立nginx.conf配置文件sql

vim nginx.confdocker

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

2、建立Mysql Compose

2.一、建立Mysql管理目錄

mkdir mysql
cd mysql
mkdir conf
cd conf

2.二、建立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=3600

mysql配置文件

3、建立Tomcat Compose

3.一、建立tomcat管理目錄與網站目錄

mkdir tomcat
mkdir -p webapps/ROOT/
cd tomcat

3.二、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 建立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
# 將本地配置文件複製到鏡像內
COPY server.xml /usr/local/apache-tomcat-8.0.46/conf

# 指定服務暴露端口
EXPOSE 8080
# 啓動tomcat服務
ENTRYPOINT ["/usr/local/apache-tomcat-8.0.46/bin/catalina.sh", "run"]

3.4 建立server.xml配置文件

vim server.xml

4、建立docker-compose.yml

4.一、在compose_nginx_tomcat目錄下建立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

    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/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

4.二、編寫測試頁面

vim webapps/ROOT/index.jsp

java ...........

4.三、執行dockerCompose 一鍵部署Nginx代理Tomcat集羣

# 管理目錄下compose_nginx_tomcat 執行該命令 -d 後臺運行
docker-compose up -d

5、測試容器服務

5.一、查看啓動狀態終端輸出

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

5.二、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 ...

5.三、測試數據庫

# 一、進入數據庫容器
docker container exec -it c764f337ffad /bin/bash

# 二、進入數據庫
mysql -h192.168.1.77 -uroot -p123456

# 三、查看建立用戶user
mysql> select user,host from mysql.user;

+------+-----------+
| user | host |
+------+-----------+
| root | % |
| user | % |
| root | localhost |
+------+-----------+
3 rows in set (0.00 sec)

5.四、瀏覽器測試nginx代理tomcat

# 一、進入nginx管理界面
docker container exec -it c764f337ffad /bin/bash

# 二、查看輸出日誌測試輪詢代理
[root@nginx /]# tail /usr/local/nginx/logs/access.log -f
