Docker

一、Docker部署应用

1.1 使用Docker部署应用必要性

有利于快速实现应用部署
有利于快速实现应用恢复

1.2 使用Docker部署应用参考资料

二、使用Docker容器实现Nginx部署

2.1 获取参考资料

2.2 运行Nginx应用容器

不在docker host暴露端口

1 2	# docker run -d --name nginx-server -v /opt/nginx-server:/usr/share/nginx/html:ro nginx 664cd1bbda4ad2a71cbd09f0c6baa9b34db80db2d69496670a960be07b9521cb

# docker ps
CONTAINER ID   IMAGE       COMMAND                  CREATED          STATUS          PORTS                                                  NAMES
664cd1bbda4a   nginx       "/docker-entrypoint.…"   4 seconds ago    Up 3 seconds    80/tcp                                                 nginx-server

# docker inspect 664 | grep IPAddress
            "SecondaryIPAddresses": null,
            "IPAddress": "172.17.0.3",
                    "IPAddress": "172.17.0.3",

# curl http://172.17.0.3
<html>
<head><title>403 Forbidden</title></head>
<body>
<center><h1>403 Forbidden</h1></center>
<hr><center>nginx/1.21.6</center>
</body>
</html>

# ls /opt
nginx-server
# echo "nginx is working" > /opt/nginx-server/index.html

1 2	# curl http://172.17.0.3 nginx is working

2.3 运行Nginx应用容器

在docker host暴露80端口

1	# docker run -d -p 80:80 --name nginx-server-port -v /opt/nginx-server-port:/usr/share/nginx/html:ro nginx

# docker ps
CONTAINER ID   IMAGE       COMMAND                  CREATED             STATUS             PORTS                                                  NAMES
74dddf51983d   nginx       "/docker-entrypoint.…"   3 seconds ago       Up 2 seconds       0.0.0.0:80->80/tcp, :::80->80/tcp                      nginx-server-port

1 2	# ls /opt nginx-server nginx-server-port

1	# echo "nginx is running" > /opt/nginx-server-port/index.html

在宿主机上访问

# docker top nginx-server-port
UID                 PID                 PPID                C                   STIME               TTY                 TIME                CMD

101                 22387               22195               0                   15:08               ?                   00:00:00            nginx: worker process

2.4 运行Nginx应用容器

挂载配置文件,需要创建一个nginx容器，把配置文件复制出来修改后使用。

1 2	# docker cp nginxwebcontainername:/etc/nginx/nginx.conf /opt/nginxcon/ 修改后即可使用

1 2	# ls /opt/nginxcon/nginx.conf /opt/nginxcon/nginx.conf

# docker run -d \
-p 82:80 --name nginx-server-conf \
-v /opt/nginx-server-conf:/usr/share/nginx/html:ro \
-v /opt/nginxcon/nginx.conf:/etc/nginx/nginx.conf:ro \
nginx

101                 25178               25005               0                   15:38               ?                   00:00:00            nginx: worker process
101                 25179               25005               0                   15:38               ?                   00:00:00            nginx: worker process

三、使用Docker容器实现Tomcat部署

3.1 获取参考资料

3.2 运行tomcat应用容器

3.2.1 不暴露端口运行

1	# docker run -d --rm tomcat:9.0

1

# docker ps
CONTAINER ID   IMAGE        COMMAND                  CREATED             STATUS             PORTS                                                  NAMES
c20a0e781246   tomcat:9.0   "catalina.sh run"        27 seconds ago      Up 25 seconds      8080/tcp                                               heuristic_cori

3.2.2 暴露端口运行

在宿主机访问

1 2	# docker exec 2fc ls /usr/local/tomcat/webapps 里面为空，所以可以添加网站文件。

3.2.3 暴露端口及添加网站文件

1 2	# docker run -d -p 8081:8080 -v /opt/tomcat-server:/usr/local/tomcat/webapps/ROOT tomcat:9.0 f456e705d48fc603b7243a435f0edd6284558c194e105d87befff2dccddc0b63

七、使用Docker容器实现Redis部署

7.1 获取参考资料

7.2 运行Redis容器

1	# mkdir -p /opt/redis/conf

1	# touch /opt/redis/conf/redis.conf

1

# docker run -p 6379:6379 --name redis -v /opt/redis/data:/data \
-v /opt/redis/conf:/etc/redis \
-d redis redis-server /etc/redis/redis.conf

# docker ps
CONTAINER ID   IMAGE                  COMMAND                  CREATED          STATUS          PORTS                                                                                  NAMES
9bd2b39cd92a   redis                  "docker-entrypoint.s…"   44 seconds ago   Up 42 seconds   0.0.0.0:6379->6379/tcp, :::6379->6379/tcp                                              redis

7.3 验证

1	# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

1	# yum -y install redis

# redis-cli -h 192.168.255.157 -p 6379

192.168.255.157:6379> set test1 a
OK
192.168.255.157:6379> get test1
"a"

7.4 Redis集群

安装redis-cluster；3主3从方式，从为了同步备份，主进行slot数据分片

编辑运行多个redis容器脚本文件
# vim redis-cluster.sh
# cat redis-cluster.sh
for port in $(seq 8001 8006); \
do \
mkdir -p /mydata/redis/node-${port}/conf
touch /mydata/redis/node-${port}/conf/redis.conf
cat << EOF >/mydata/redis/node-${port}/conf/redis.conf
port ${port}
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
cluster-announce-ip 192.168.255.157
cluster-announce-port ${port}
cluster-announce-bus-port 1${port}
appendonly yes
EOF
docker run -p ${port}:${port} -p 1${port}:1${port} --name redis-${port} \
-v /mydata/redis/node-${port}/data:/data \
-v /mydata/redis/node-${port}/conf/redis.conf:/etc/redis/redis.conf \
-d redis:5.0.7 redis-server /etc/redis/redis.conf; \
done

1 2	执行脚本 # sh redis-cluster.sh

查看已运行容器
# docker ps
