centos6使用docker部署redis主从数据库操作示例

本文实例讲述了centos6使用docker部署redis主从数据库操作。分享给大家供大家参考，具体如下：

目录结构：

/redis

    /Dockerfile

    /Readme

    /redis-3.2.8.tar.gz

    /start.sh

Dockerfile:

FROM centos
MAINTAINER qiongtao.li hnatao@126.com
ADD ./redis-3.2.8.tar.gz /opt
ADD ./start.sh /opt/start_redis.sh
RUN echo "Asia/shanghai" > /etc/timezone \
 && cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
 && yum -y install gcc make \
 && ln -s /opt/redis-3.2.8 /opt/redis \
 && cd /opt/redis && make && make install
EXPOSE 6379
ENTRYPOINT ["sh", "/opt/start_redis.sh"]

start.sh

role=$1
port=6379
password=Abc123
redis_conf=/opt/redis/redis.conf
dir=/data/redis
logfile=/data/redis/redis.log
mkdir -p $dir
sed -i "s|bind 127.0.0.1|bind 0.0.0.0|g" $redis_conf
sed -i "s|# requirepass foobared|requirepass ${password}|g" $redis_conf
sed -i "s|dir ./|dir ${dir}|g" $redis_conf
sed -i "s|logfile \"\"|logfile ${logfile}|g" $redis_conf
if [ "$role" == "slave" ]; then
 echo "slave"
 sed -i "s|# slaveof  |slaveof redis-master ${port}|g" $redis_conf
 sed -i "s|# masterauth |masterauth ${password}|g" $redis_conf
else
 echo "master"
fi
redis-server $redis_conf

Readme

docker rm -f redis-master redis-slave-1 redis-slave-2
docker rmi -f redis
docker build -t redis .
docker run -d --name redis-master redis
docker run -d --name redis-slave-1 --link redis-master:redis-master redis slave
docker run -d --name redis-slave-2 --link redis-master:redis-master redis slave
docker ps -a
docker exec redis-master redis-cli -a Abc123 set name hnatao
docker exec redis-master redis-cli -a Abc123 get name
docker exec redis-slave-1 redis-cli -a Abc123 get name
docker exec redis-slave-2 redis-cli -a Abc123 get name
docker exec redis-master grep -E "bind|dir|require|logfile|slaveof|masterauth" /opt/redis/redis.conf
docker exec redis-slave-1 grep -E "bind|dir|require|logfile|slaveof|masterauth" /opt/redis/redis.conf
docker exec redis-slave-2 grep -E "bind|dir|require|logfile|slaveof|masterauth" /opt/redis/redis.conf
docker exec redis-master redis-cli -a Abc123 info
docker exec redis-slave-1 redis-cli -a Abc123 info
docker exec redis-slave-2 redis-cli -a Abc123 info

测试安装部署

cat Readme|while read line; do $line; done

希望本文所述对大家Docker容器使用有所帮助。
