docker 實現nginx+tomcat+mysql
[一].建立資料目錄
1.建立nginx資料目錄
mkdir -p /app/data/nginx/{conf,conf.d,html,logs}
2.建立mysql資料目錄
mkdir -p /app/data/mysql/{conf,mysql_init_data}
3.建立tomcat資料目錄
mkdir -p /app/data/tomcat
[二].映象構建
#nginx,tomcat,mysql 都可以自建dockerfile構建,由於個人構建映象偏大等原因。所以這裡nginx,mysql採用官方映象,tomcat 通過dockerfile自行構建。 構建tomcat映象 建立dockerfile檔案及存放目錄 mkdir -p /app/Docker/Tomcat cd /app/Docker/Tomcat/ cat>/app/Docker/Tomcat/Dockerfile<<EOF FROM centos #指定基礎映象來自於哪裡 MAINTAINER Tomcat7 images #進行說明 ADD jdk1.8.0_144/ /opt/jdk #新增jdk ADD apache-tomcat-7.0.75 /opt/tomcat #新增tomcat #COPY xxx.war /opt/tomcat/webapps/ #war包可進行掛在或者直接拷貝 EXPOSE 8080 #開發埠 RUN /usr/bin/sed -i '107a JAVA_HOME=/opt/jdk' /opt/tomcat/bin/catalina.sh #配置環境變數 CMD ["/bin/bash","-c","/opt/tomcat/bin/catalina.sh run"] #開啟Tomcat EOF 構建映象: docker build -t tomcat7:01 /app/Docker/Tomcat docker images檢視映象
[三].建立tomcat資料檔案
#用於與映象內檔案格式等保持一致，這裡我們先啟動一個容器將需要後續改動的配置拷貝出來 cd /app/tomcat docker run -d --name "tomcat01" tomcat:01 #拷貝出需要後續配置的檔案（保持與映象內檔案格式相同） docker cp -a tomcat01:/opt/tomcat/webapps ./ docker cp -a tomcat01:/opt/tomcat/logs ./ docker cp -a tomcat01:/opt/tomcat/bin ./ docker cp -a tomcat01:/opt/tomcat/conf ./ docker rm -f tomcat01 echo "歡迎使用tomcat7-jdk8">>/app/data/tomcat/webapps/ROOT/index.html docker rm -f tomcat01
[四].建立nginx配置檔案
cat >/app/data/nginx/conf/nginx.conf<<EOF
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#啟用gzip
gzip on;
#需要壓縮檔案的最小尺寸，單位是B
gzip_min_length 1000;
#gzip檔案快取大小
gzip_buffers 4 8k; # 4和8之間有個空格的啊
#gzip壓縮檔案格式，以下涵蓋了一般所需的型別
gzip_types text/plain application/x-javascript text/css application/xml application/javascript application/json;
#gzip壓縮等級，數值越高壓縮得越狠，也越佔資源
gzip_comp_level 3;
include /etc/nginx/conf.d/*.conf;
}
EOF
cat >/app/data/nginx/conf.d/bestyunyan.culb.conf<<EOF
upstream my_server{
#ip_hash;
server tomcat01:80;
#server 124.207.22.13:8080;
#hash $request_uri; 第三方模組
}
server{
listen 80;
server_name 172.16.235.11;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-Nginx-Proxy true;
proxy_pass http://my_server;
proxy_redirect off;
}
}
EOF[五].建立mysql配置檔案
cat >/app/data/mysql/conf/my.cnf<<EOF
[mysqld]
user=mysql
character-set-server=utf8
default_authentication_plugin=mysql_native_password
max_connections=3000
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
EOF
cat /app/data/mysql/mysql_init_data/init.sql
#建立資料庫
DROP database IF EXISTS `wyl_database`;
create database `wyl_database` default character set utf8 collate utf8_general_ci;
#切換到test_data資料庫
use wyl_database;
#建立建表
DROP TABLE IF EXISTS `person`;
CREATE TABLE `user` (
`id` bigint(20) NOT NULL,
`name` varchar(255) DEFAULT NULL,
`age` bigint(20) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
#插入資料插
INSERT INTO `user` (`id`,`name`,`age` ) VALUES (0,'wangyunlong',18);
[6].建立docker-compose檔案
#三版本:
version: '3' #指定是docker compose版本
services: #指定服務

aliases:

volumes:
web_data:
#通過docker volume ls 列出資料卷
#docker volume inspect xxx #檢視持久化到本地的具體位置
networks:

#以上volumes語法採用3版本，2版本請參考:
#https://stackoverflow.com/questions/45494746/docker-compose-volumes-from-usage-example
#compose.yml語法:
