article 2024/11/15 13:32:30

获取配置

#----------------------------------------------------------
拉取镜像 docker pull redis:latest
#----------------------------------------------------------
创建容器 docker run --name redis -d redis:latest
#----------------------------------------------------------
获取版本 docker exec redis redis-server --version
#----------------------------------------------------------
删除容器 docker rm -f redis
#----------------------------------------------------------
获取配置 http://download.redis.io/releases 解压获取 redis.conf sentinel.conf
注意事项 redis.conf sentinel.conf 同镜像中Redis版本必须一致 否则容器启动异常
#----------------------------------------------------------

编辑配置
