docker之部署redis

首先需要拉取鏡像

docker search redis

[root@izwz99346f3qg0hwroojwpz ~]# docker search redis

OFFICIAL  ok 代表這是官方做的鏡像
 

拉取redis鏡像

docker pull redis 

創建並運行一個名爲 master 的容器

docker run \ 

-p 6379:6379 \ 

-v $PWD/data:/data \ 

-v $PWD/conf/redis.conf:/etc/redis/redis.conf \

--privileged=true \ 

--name master \ 

-d redis redis-server /etc/redis/redis.conf

# 命令分解

docker run \ -p 6379:6379 \

# 端口映射 宿主機:容器

v $PWD/data:/data:rw \

# 映射數據目錄 rw 爲讀寫

-v $PWD/conf/redis.conf:/etc/redis/redis.conf:ro \

# 掛載配置文件 ro 爲readonly

--privileged=true \

# 給與一些權限

--name master \

# 給容器起個名字

-d redis redis-server /etc/redis/redis.conf

# deamon 運行容器 並使用配置文件啓動容器內的鏡像實例

redis-server

# redis-cli 訪問  -it 交互的虛擬終端

docker run -it --link myredis:redis --rm redis redis-cli -h redis -p 6379

 --rm 退出是刪除此容器

 

主從配置

 

*** 新建容器 redis-slave

查看 redis master 的內部 ip

docker inspect redis

#Networks 可以得到 redis master 的 ip 地址

"NetworkSettings": { 
    "Ports": { 
        "6379/tcp": [ { "HostIp": "0.0.0.0", "HostPort": "6379" } ] }, 
                       ... "Gateway":"192.168.0.1", ... "IPAddress": "192.168.0.3",#ip ...     
                        "Networks": { "bridge": { ... "Gateway": "192.168.0.1",     
                        "IPAddress": "192.168.0.3",#ip ... } } } 

修改 redis-slave 的配置文件

# 主地址 slaveof master-ip master-port #

主認證 master auth

#重啓 redis-slave

docker restart redis-slave

登錄 redis master 使用 info 命令查看從的狀態

##主要是記錄redis在docker中安裝，主從集羣配置以後再研究一下。
