CentOS7+Docker+Redis3環境搭建

建立一個redis docker容器
首先，我們先為redis建立一個Dockerfile檔案和fix-permissions.sh檔案
Dockerfile：
Dockerfile相關教程地址（官方GitHub地址）Dockerfile# "ported" by Adam Miller <[email protected]> from # https://github.com/fedora-cloud/Fedora-Dockerfiles # # Originally written for Fedora-Dockerfiles by # Aditya Patawari <[email protected]> FROM centos:centos7 MAINTAINER The CentOS Project <[email protected]> RUN yum -y update; yum clean all RUN yum -y install epel-release; yum clean all RUN yum -y install redis; yum clean all EXPOSE 6379 # log on stdout instead of writing to file RUN sed -i 's/^\(logfile\s*\).*$/\1""/g' /etc/redis.conf # Fix permissions to allow for running on openshift COPY fix-permissions.sh ./ RUN ./fix-permissions.sh /var/log/redis/ && \ ./fix-permissions.sh /var/lib/redis/ # By default will run as random user on openshift and the redis user (997) # everywhere else USER 997 ENTRYPOINT ["redis-server"] CMD ["/etc/redis.conf", "--bind", "0.0.0.0"]
fix-permissions.sh：(記得給檔案加上執行許可權（sudo chmod +x fix-permissions.sh）)
<span style="font-size:18px;">#!/bin/sh # Taken from https://raw.githubusercontent.com/openshift/sti-base/master/bin/fix-permissions # Fix permissions on the given directory to allow group read/write of # regular files and execute of directories. chgrp -R 0 $1 chmod -R g+rw $1 find $1 -type d -exec chmod g+x {} +</span>
接著,構建映象
<span style="font-size:18px;">docker build -t centos7/redis:centos7 .</span>
到此，redis的映象就已經安裝成功了。
執行例項
docker run -d -p 6379:6379 centos7/redis:centos7docker run -d -p 6479:6479 centos7/redis:centos7
進入容器
先查詢出Pid是什麼：
docker inspect --format "{{ .State.Pid}}" <container-id> nsenter --target 6537 --mount --uts --ipc --net --pid進入到容器裡面；
直接通過輸入：redis-cli就可以連上redis了。
[[email protected] ~]# docker inspect --format "{{ .State.Pid}}" e5a90a839f40
6537
[[email protected] ~]# nsenter --target 6537 --mount --uts --ipc --net --pid
[[email protected] /]# redis-cli
127.0.0.1:6379>
安裝就到這裡了，怎麼用，在下一篇部落格再繼續說！
