【dockerredis】用docker容器运行单机redis
一、实验环境
操作系统：CentOS7.5 Minimal
docker版本：18.06-ce
redis版本：6.0.6
二、安装docker
关闭selinux
# setenforce 0
# sed -i 's/^SELINUX=.*/SELINUX=permissive/g' /etc/selinux/config
下载docker二进制安装包
# yum -y install wget
# wget https://download.docker.com/linux/static/stable/x86_64/docker-18.06.0-ce.tgz
# tar -zxf docker-18.06.0-ce.tgz
# ll ./docker
# cp ./docker/docker* /usr/bin
创建docker服务的unit文件
# vim /etc/systemd/system/docker.service
##############################################################
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target
[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.
#TasksMax=infinity
TimeoutStartSec=0
# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes
# kill only the docker process, not all processes in the cgroup
KillMode=process
# restart the docker process if it exits prematurely
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s
[Install]
WantedBy=multi-user.target

启动docker服务，设置开机自启
# systemctl daemon-reload
# systemctl start docker
# systemctl status docker
# systemctl enable docker
# docker info
# docker version
设置镜像加速
# curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://f1361db2.m.daocloud.io
# systemctl restart docker
# cat /etc/docker/daemon.json
# python -m json.tool /etc/docker/daemon.json
三、 拉取redis镜像，启动容器
# docker pull redis
# docker run -it --rm redis redis-cli -v
# docker tag redis:latest redis:6.0.6
# docker run -it --rm redis cat /etc/passwd
# mkdir /opt/redisdata
# chown -R 999:999 /opt/redisdata
# docker run -d --name redis -v /opt/redisdata:/data -p 6379:6379 redis:6.0.6 redis-server --appendonly yes
# docker exec -it redis redis-cli config set requirepass "Redis@123"
# docker logs redis
# docker stop redis
# docker rm redis
四、将redis注册成系统服务
# vim /etc/systemd/system/redis.service

# systemctl daemon-reload

# systemctl enable redis
# docker exec -it redis redis-cli -a "Redis@123"
