  • redis5.0单机，哨兵和Cluster

    日常学习。。。。redis单机部署和高可用。通过docker部署，均未做数据持久化。

    一，单机

    dockerfile文件如下

    from centos:7
    RUN yum install vim net-tools tcl make gcc -y
    ADD redis-5.0.7.tar.gz /opt/
    RUN cd /opt/redis-5.0.7
      && make
      && make test
      && make install
    RUN cp /opt/redis-5.0.7/redis.conf /etc/redis.conf
      && sed -i 's/bind 127.0.0.1/#bind 127.0.0.1/g' /etc/redis.conf
      && sed -i 's/daemonize no/daemonize yes/g' /etc/redis.conf
      && sed -i 's/appendonly no/appendonly yes/g' /etc/redis.conf
      && sed -i '$a equirepass redis' /etc/redis.conf
    RUN echo -e "#!/bin/bash redis-server /etc/redis.conf sh " >> /root/run.sh
    RUN chmod a+x /root/run.sh
    CMD ["/root/run.sh"]

    创建镜像

    [root@dou redis]# docker build -t redis:v1 .

[root@dou redis]#

    运行容器

    docker run -itd --network doufy --ip 172.19.0.30 --name redis01 -h redis01 redis:v1

    连接测试

    [root@redis01 /]# redis-cli -h 172.19.0.30 -p 6379 -a redis
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.

    二，主从复制

     docker file文件如下

    [root@dou redis]# more Dockerfile-master
from centos:7
RUN yum install vim net-tools tcl make gcc -y
ADD redis-5.0.7.tar.gz /opt/
RUN cd /opt/redis-5.0.7  
    && make       
    && make test  
    && make install
RUN  cp /opt/redis-5.0.7/redis.conf  /etc/redis.conf 
    &&  sed -i 's/bind 127.0.0.1/#bind 127.0.0.1/g' /etc/redis.conf 
    &&  sed -i 's/daemonize no/daemonize yes/g'  /etc/redis.conf 
    &&  sed -i 's/appendonly no/appendonly yes/g'  /etc/redis.conf 
    &&  sed -i '$a
equirepass redis'  /etc/redis.conf
COPY run.sh  /root/run.sh
RUN chmod a+x /root/run.sh
CMD ["/root/run.sh"]

[root@dou redis]# more Dockerfile-slave
from centos:7
RUN yum install vim net-tools tcl make gcc -y
ADD redis-5.0.7.tar.gz /opt/
RUN cd /opt/redis-5.0.7  
    && make       
    && make test  
    && make install
RUN  cp /opt/redis-5.0.7/redis.conf  /etc/redis.conf 
    &&  sed -i 's/bind 127.0.0.1/#bind 127.0.0.1/g' /etc/redis.conf 
    &&  sed -i 's/daemonize no/daemonize yes/g'  /etc/redis.conf 
    &&  sed -i 's/appendonly no/appendonly yes/g'  /etc/redis.conf 
    &&  sed -i '$a
equirepass redis'  /etc/redis.conf 
    &&  sed -i '$a
eplicaof 172.19.0.51 6379'  /etc/redis.conf 
    &&  sed -i '$amasterauth redis'  /etc/redis.conf
COPY run.sh /root/run.sh
RUN chmod a+x /root/run.sh
CMD ["/root/run.sh"]

[root@dou redis]# more docker-compose.yml

    max-file: '5'

    hostname: master

         ipv4_address: 172.19.0.51
    volumes:
      -  /etc/localtime:/etc/localtime:ro
      #测试不持久化了
  slave1:
    image: redis:s2
    logging: *default-logging
    restart: "no"
    hostname: slave1
    networks:
       doufy:
         ipv4_address: 172.19.0.52

    volumes:

    doufy:
      external: true
    View Code

    创建镜像

    docker build -t redis:m2 -f Dockerfile-master .
docker build -t redis:s2 -f Dockerfile-slave .

    运行容器

    docker-compose up -d

    连接测试

    [root@dou redis]# docker-compose up -d
Creating redis_slave2_1  ... done
Creating redis_slave1_1  ... done
Creating redis_master1_1 ... done
[root@dou redis]# docker exec -it redis_master1_1 bash -c "echo 'info replication'|redis-cli -a redis"
# Replication

connected_slaves:2
slave0:ip=172.19.0.52,port=6379,state=online,offset=420,lag=1
slave1:ip=172.19.0.53,port=6379,state=online,offset=420,lag=1
master_replid:bbe4270c4f3f5e7e72923413ba5907dc9d5513c7
master_replid2:0000000000000000000000000000000000000000
master_repl_offset:420

repl_backlog_active:1
repl_backlog_size:1048576
repl_backlog_first_byte_offset:1
repl_backlog_histlen:420
[root@dou redis]#

    测试

    在master节点设置key，slave节点获取key

    master节点
    [root@master /]# redis-cli -a redis
    127.0.0.1:6379> set doufy caiji
    OK
    127.0.0.1:6379> get doufy
    "caiji"
    127.0.0.1:6379>
slave节点
[root@slave1 /]# redis-cli -a redis

    127.0.0.1:6379> get doufy
    "caiji"
    127.0.0.1:6379>

master删除，slave也没了，主从复制到此结束

    三， 哨兵模式

     docker file如下

    [root@dou redis]# more Dockerfile-master

    &&  sed -i 's/daemonize no/daemonize yes/g'  /etc/redis.conf 
    &&  sed -i 's/appendonly no/appendonly yes/g'  /etc/redis.conf 
    &&  sed -i '$a

RUN mkdir  /var/log/redis &&  touch /var/log/redis/sentine.log  && chmod 755 /var/log/redis -R
COPY run.sh  /root/run.sh
RUN chmod a+x /root/run.sh
CMD ["/root/run.sh"]


[root@dou redis]# more Dockerfile-slave
