Docker部署前后端分离项目
1.通过GIT将前后端代码clone到本地并打包1.1.克隆前端代码并打包1.1.1.克隆代码git clone https://github.com/renrenio/renren-fast-vue.git代码克隆完毕后,请执行以下操作:修改renren-fast-vue/config/index.js中的port为9527;修改renren-fast-vue/static/...
1.通过GIT将前后端代码clone到本地并打包
1.1.克隆前端代码并打包
1.1.1.克隆代码
git clone https://github.com/renrenio/renren-fast-vue.git
代码克隆完毕后,请执行以下操作:
- 修改renren-fast-vue/config/index.js中的port为9527;
- 修改renren-fast-vue/static/config/index-prod.js中的api接口请求地址中的localhost为你的后台服务器IP;
1.1.2.打包代码
cd renren-fast-vue
# 安装依赖
npm install --registry=https://registry.npm.taobao.org
# 如果直接 【安装依赖】 报错的话,请先单独安装 【chromedriver】,单独安装前请先删除项目下的**node_modules**文件夹,若能直接安装成功,则可以跳过此步骤
npm install chromedriver --chromedriver_cdnurl=http://cdn.npm.taobao.org/dist/chromedriver
# 安装依赖成功后,打包项目
npm run build
至此,renren-fast-vue目录下就会生成dist文件夹,这就是打包好的前端代码;
1.2.克隆后端代码并打包
1.2.1.克隆代码
操作指令:
git clone https://gitee.com/renrenio/renren-fast.git
由于application.yml中环境配的是dev,由
spring: profiles: active: dev
中可以看出,代码克隆完毕后,请执行以下操作:
- 修改由于application-dev.yml中的
spring: datasource: druid: username: renren
为spring: datasource: druid: username: root
- 修改由于application-dev.yml中的
spring: datasource: druid: password: 123456
为spring: datasource: druid: password: root
1.2.2.打包代码
操作指令:
mvn clean install -Dmaven.test.skip=true
操作命令说明:
- clean 清除之前的打包
- install 本地打包
- -Dmaven.test.skip=true 跳过测试代码
至此,renren-fast目录下就会生成target文件夹,文件夹中的renren-fast.jar就是打包好的后端代码;
2.在 CentOS 7 服务器上安装docker
具体操作请参考:CentOS 搭建 Docker 环境
3.使用docker安装mysql
3.1.拉取指定版本的mysql镜像
操作指令:
# 拉取mysql
docker pull mysql:5.7.25
# 查看已拉取的本地镜像
docker images
3.2.创建data,conf,logs目录以及配置文件my.cnf
3.2.1.创建data,conf,logs目录
操作指令:
mkdir /home/soft/renren/mysql/data -p
mkdir /home/soft/renren/mysql/conf
mkdir /home/soft/renren/mysql/logs
3.2.2.创建my.cnf配置文件
操作指令:
# 进入mysql目录
cd /home/soft/renren/mysql
# 创建配置文件
touch my.cnf
# 编辑文件
vim my.cnf
# 将下方my.cnf文件的内容复制然后粘贴到服务器上的my.cnf中;
# 按键盘上的esc退出编辑模式,输入英文分号,输入wq保存并退出;
配置文件my.cnf

[client]
port = 3306
socket = /var/run/mysqld/mysqld.sock
[mysqld_safe]
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
nice = 0
[mysqld]
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
explicit_defaults_for_timestamp
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
#bind-address = 127.0.0.1
#log-error = /var/log/mysql/error.log
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# * IMPORTANT: Additional settings that can override those from this file!
# The files must end with '.cnf', otherwise they'll be ignored.
#
!includedir /etc/mysql/conf.d/
3.2.运行mysql容器,初始化renren-fast项目的数据库表
3.2.1.运行mysql容器
操作指令:
docker run --restart=always -p 3306:3306 -d --name mysql -e MYSQL_ROOT_PASSWORD=root -v /home/soft/renren/mysql/conf:/etc/mysql/conf.d -v /home/soft/renren/mysql/logs:/var/log/mysql -v /home/soft/renren/mysql/data:/var/lib/mysql mysql:5.7.25
运行完毕后,请等待大约两分钟,因为mysql的初始化比较耗时间;通过mysql的客户端工具能连上mysql,则说明启动完成;
3.2.2.初始化renren-fast项目的数据库表
通过mysql的客户端工具能连上mysql,则说明启动完成;
4.使用docker安装redis
4.1.拉取redis镜像并运行容器
docker pull redis
docker run --restart=always --name redis -p 6379:6379 -d redis
4.使用docker运行后端项目renre-fast.jar
4.1.拉取后端项目运行所需的java镜像并运行
# 拉取Java容器
docker pull java
# 创建映射所用的文件夹
mkdir /home/soft/renren/back-end -p
# 通过FTP工具将renre-fast.jar上传到back-end文件夹下后执行以下操作
# 运行Java容器
docker run -it -d --name renren-fast -v /home/soft/renren/back-end:/home/soft --net=host java
运行容器时使用 -v 做了文件映射,把真实主机上的/home/soft/renren/back-end目录下的文件和文件夹映射到容器内的/home/soft目录下;–net=host是虚拟机与主机共享IP;
4.2.部署后端项目renre-fast.jar
使用Xshell的复制当前会话功能,在新打开的窗口中执行以下命令;
# 进入Java容器
docker exec -it renren-fast bash
# 进入jar包所在目录
cd /home/soft
# 后台运行jar包并将日志输出到文件nohup.out中
nohup java -jar renre-fast.jar > nohup.out
注意:此时切勿按Ctrl+C,否则会直接终止正在运行的进程;此时直接点击标签栏上的关闭按钮关闭该窗口,切勿输入命令exit退出容器,因为exit会停止当前运行的容器并退出;
4.3.查看后端项目renre-fast.jar运行结果
由于做了虚拟机和真实宿主机之间的映射,可以直接通过以下命令查看日志
tail -fn 200 /home/soft/renren/back-end/nohup.out
访问http://你的IP:8080/swager/index.html,如果能正常访问,则说明后台项目配置完毕;如果不能访问,但是日志中又显示启动完成,请查看下是否关闭防火墙或者修改防火墙策略,如果是云服务,请查看是否在安全组中允许该端口出入站;
5.使用docker运行前端项目renre-fast-vue
5.1.拉取后端项目运行所需的nginx镜像并创建映射目录,nginx配置文件
# 拉取nginx
docker pull nginx
# 创建conf,logs
mkdir /home/soft/renren/nginx/conf -p
mkdir /home/soft/renren/nginx/logs
# 进入nginx配置文件夹
cd /home/soft/renren/nginx/conf
# 创建nginx配置文件
touch nginx.conf
# 编辑nginx配置文件
vim nginx.conf
# 将下方nginx.conf文件的内容复制然后粘贴到服务器上的nginx.conf中;
# 按键盘上的esc退出编辑模式,输入英文分号,输入wq保存并退出;
配置文件:nginx.conf
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;
#gzip on;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 10m;
client_body_buffer_size 128k;
proxy_connect_timeout 5s;
proxy_send_timeout 5s;
proxy_read_timeout 5s;
proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
server {
listen 9527;
server_name localhost;
location / {
root /home/soft/renren-vue;
index index.html;
}
}
}
5.2.上传前端项目到服务器并运行项目
# 创建前端项目存放的文件夹
mkdir /home/soft/renren/fore-end
# 通过FTP工具将前端项目打包好的dist文件夹下的所有文件放到fore-end目录中,然后执行以下命令
docker run -it -d --name renren-vue -v /home/soft/renren/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /home/soft/renren/nginx/logs:/var/log/nginx/ -v /home/soft/renren/fore-end:/home/soft/renren-vue --privileged --net=host nginx
此时访问http://你的IP地址:9527,看看能否正常访问,登录界面的验证码是否正确显示,如果正确显示,则表明你所搭建的前后端分离项目成功;
