# 修改参数，SELINUX=参数，参数可选（enforcing、permissive、disabled）
SELINUX=disabled

6. Start docker service

systemctl daemon-reload            #刷新系统服务配置文件
systemctl start docker.service     #启动docker
systemctl enable docker.service    #配置开机自启
systemctl status docker.service    #查看docker状态 

Docker configuration modification

Join Portainer management and use

• Add configuration "-H tcp://0.0.0.0:2375" to enable port 2375 of docker api.

Modify the IP address of Docker0

vi /etc/default/docker 
# 写入想要修改 IP 地址段
DOCKER_OPTS="--bip=172.20.1.0/16"

Modify Docker storage location

• Add the configuration "--data-root=/home/southgisdata/docker" to modify the storage directory, and /home/southgisdata/docker is the adjusted back-end storage directory.

Set container retention log size

Create a new "/etc/docker/daemon.json" if it exists. There is no need to create a new one. Add log-dirver and log-opts parameters, the sample is as follows:
Note: You need to start the docker service before making modifications, and restart the docker service after modification.

# 编辑 daemon.json 文件
vi /etc/docker/daemon.json
# 写入
{
  "log-driver":"json-file",
  "log-opts": {"max-size":"500m", "max-file":"4"}
}

max-size=500m means that the upper limit of the log size of a container is 500M.
max-file=4 means that a container has three logs, namely id+.json, id+1.json, id+2.json, id+ 3.json.

Portainer installation

Download address: https://hub.docker.com/r/portainer/portainer-ce/tags

1. Import image files offline

docker load -i image_portainer.tar

2. Create data directory

cd /home &&mkdir portainer_data

3. Run container

docker run -d --name portainer --restart=always -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock -v /opt/portainer_data/:/data 192.168.10.156/fpa/portainer:latest
