【性能测试】Linux下Docker安装与docker-compose管理容器（超细整理）_linux 安装和检查docker-compose

前言

1、Linux下Docker安装

1）安装依赖包

yum install -y yum-utils device-mapper-persistent-data lvm2

 

2）安装docker

yum install -y docker

3）启动和关闭docker

启动：systemctl start docker
关闭：systemctl stop docker

2、docker-compose管理容器

下载docker-compose

1）下载依赖

执行命令：

curl -L https://get.daocloud.io/docker/compose/releases/download/1.26.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

2）给下载目录授予权限

chomod 777 /usr/local/bin/docker-compose

验证docker-compose是否安装成功

docker-compose –v

创建docker-compose.yaml配置文件

1）在root目录下创建一个docker-compose的目录

cd /root
 
mkdir docker-compose
touch docker-compose.yml

添加以下配置：

version: '3'
 
services:
 
mysql:
 
image: mysql:5.7
 
privileged: true
 
ports:
 
- 3306:3306
 
environment:
 
- MYSQL_ROOT_PASSWORD=Testfan#123
 
volumes:
 
- /root/docker/mysql/conf/my.cnf:/etc/mysql/my.cnf
 
- /root/docker/mysql/data:/var/lib/mysql
 
networks:
 
- mtx
 
redis:
 
image: redis
 
privileged: true
 
ports:
 
- 6379:6379
 
volumes:
 
- /root/docker/redis/conf/redis.conf:/etc/redis/redis.conf
 
networks:
 
- mtx
 
command: redis-server /etc/redis/redis.conf
 
tomcat-pinter-1:
 
image: tomcat:8.5.0-jre8
 
privileged: true
 
ports:
 
- 8080:8080
 
volumes:
 
- /root/docker/tomcat/webapps:/usr/local/tomcat/webapps
 
networks:
 
- mtx
 
depends_on:
 
- mysql
 
- redis
 
tomcat-pinter-2:
 
image: tomcat:8.5.0-jre8
 
privileged: true
 
ports:
 
- 8090:8080
 
volumes:
 
- /root/docker/tomcat/webapps:/usr/local/tomcat/webapps
 
networks:
 
- mtx
 
depends_on:
 
- mysql
 
- redis
 
nginx:
 
image: nginx
 
privileged: true
 
ports:
 
- 80:80
 
volumes:
 
- /root/docker/nginx/conf.d:/etc/nginx/conf.d
 
- /root/docker/nginx/logs:/var/log/nginx
 
networks:
 
- mtx
 
depends_on:
 
- tomcat-pinter-1
 
- tomcat-pinter-2
 
networks:
 
mtx:
 
driver: bridge

2）关闭以前启动的容器

docker stop 84c4fa341d62
docker stop 4672429de27b
docker stop de5032a8efd7
docker stop 8ddf607e7359
docker stop 52b94a9fb918

3）在docker-compose.yml同级目录下启动

docker-compose up –d

4）浏览器中检查是否可以访问

5）docker-compose其他命令

后台启动容器：docker-compose up -d [容器名]
停止并删除容器：docker-compose down [容器名]

停止容器：docker-compose stop [容器名]
重启容器：docker-compose restart [容器名]
查看容器：docker-compose ps [容器名]
查看日志：docker-compose logs [容器名]
