nginx负载均衡docker部署

一、nginx负载均衡docker部署

3.1 创建文件夹

在home用户目录下 创建redis的相关文件夹

mkdir -p /home/jun/docker/nginx
cd /home/jun/docker/nginx
创建三个目录
mkdir shell  #构建、启动、停止等脚本
mkdir dockerfile  #dockerfile目录
mkdir volumes  #挂载配置、日志、数据文件

3.2 准备dockerfile文件

cd /home/hd/docker/nginx/dockerfile

vim Dockerfile

Dockerfile内容

FROM nginx:1.21.3-alpine

USER hd

WORKDIR /home/hd

#CMD

3.3 通过dockerfile构建镜像

创建shell的中脚本文件

build脚本 :构建docker镜像

vi build

#!/bin/bash
DOCKER_PATH=$PWD/../
sudo docker build -f $DOCKER_PATH/dockerfile/Dockerfile  -t nginx:1.21.3-alpine $DOCKER_PATH/dockerfile/

run脚本

vi run ：构建并启动docker容器

#!/bin/bash
DOCKER_PATH=$PWD/../
NAME=nginx
PORT=80
VERSION=1.21.3-alpine
docker run -d \
  -p ${PORT}:80 \
  -p 443:443 \
  -p 8080:8080 \
  --name ${NAME} \
  -v /etc/localtime:/etc/localtime \
  -v $DOCKER_PATH/volumes/conf/nginx.conf:/etc/nginx/nginx.conf \
  -v $DOCKER_PATH/volumes/log:/var/log/nginx \
  -v $DOCKER_PATH/volumes/conf/ssl.crt:/etc/nginx/ssl.crt \
  -v $DOCKER_PATH/volumes/conf/ssl_nopass.key:/etc/nginx/ssl_nopass.key \
  --restart=unless-stopped nginx:${VERSION}

exec脚本

vi exec ：进入已启动成功的docker容器

#!/bin/sh
sudo docker exec -it nginx /bin/bash

logs脚本

vi logs ：docker容器日志 启动容器失败时，可执行查询日志

#!/bin/bash
sudo docker logs nginx

restart

vi restart ：docker容器重启

#!/bin/sh
sudo docker restart nginx

rm

vi rm ：删除docker容器

#!/bin/sh
sudo docker rm nginx

rmi

vi rmi：删除docker镜像 dockerfile文件修改时 才需要执行

#!/bin/sh
sudo docker rmi nginx:1.21.3-alpine 

start

vi start：启动docker容器

#!/bin/sh
sudo docker start  nginx

stop

vi stop：停止docker容器

#!/bin/sh
sudo docker stop nginx

文件权限
chown -R hd:hd /home/hd/docker-files/nginx
可执行文件
chmod +x /home/hd/docker-files/nginx/shell/*

user root;
pid  /var/run/nginx.pid;
error_log /var/log/nginx/error.log warn;
