1. 前期准备

新部署前可以从仓库（repository）下载 redis 镜像，或者从已有部署中的镜像生成文件：

# 查看当前本地镜像 docker images # 生成本地镜像文件 docker save <IMAGE ID> -o redis_503.tar

2. 导入镜像

代码语言：javascript复制
# 在新部署的机器上导入镜像
docker load -i redis_503.tar
docker images

3. 部署redis master脚本

redis-master-deploy.sh 文件内容如下：

代码语言：javascript复制
#!/bin/bash

if [ ! -n "$1" ] ;then
    echo "执行方式：redis-master-deploy.sh 镜像 redis起始端口号，如 redis-master-deploy.sh a.com:8443/dockerhub/redis:5.0.3 7001"
    exit
fi

if [ ! -n "$2" ] ;then
    echo "执行方式：redis-master-deploy.sh 镜像 redis起始端口号，如 redis-master-deploy.sh a.com:8443/dockerhub/redis:5.0.3 7001"
    exit
fi

image=${1////\/}
port=$2
len=${#port}

for ((var=0; var<$len; var  ))
do
   a=${port:$var:1}
   if [ $var -eq 0 ]; then
     sentinel_port=$(($a 1))
   elif [ $var -eq $(($len-1)) ]; then
     sentinel_port=${sentinel_port}1
   else
     sentinel_port=${sentinel_port}0
   fi
done

# redis-server
for i in {1..16}
do
  old_port=$((7000 $i))
  new_port=$(($port   $i -1))
  sed_para=$sed_para"s/${old_port}/${new_port}/g;"
  mkdir -p /usr/local/etc/redis/redis$i/
  cp -f ~/redis.conf.template /usr/local/etc/redis/redis$i/redis.conf
  sed -i 's/7001/'"${new_port}"'/g;s/redis1/redis'"${i}"'/g;' /usr/local/etc/redis/redis$i/redis.conf
done

cp -f ~/docker-compose-server.yml.template /usr/local/etc/redis/docker-compose.yml
sed -e ${sed_para} -i /usr/local/etc/redis/docker-compose.yml
sed -i 's/a.com:8443/dockerhub/redis:5.0.3/'"${image}"'/g;' /usr/local/etc/redis/docker-compose.yml

# sentinel
mkdir -p /usr/local/etc/redis/sentinel/
cp -f ~/sentinel.conf.template /usr/local/etc/redis/sentinel/sentinel.conf
ip=`hostname -I | awk '{print $1}'`
sed -i 's/172.18.29.56/'"${ip}"'/g;s/8001/'"${sentinel_port}"'/g;' /usr/local/etc/redis/sentinel/sentinel.conf
sed -e ${sed_para} -i /usr/local/etc/redis/sentinel/sentinel.conf
cp -f ~/docker-compose-sentinel.yml.template /usr/local/etc/redis/sentinel/docker-compose.yml
sed -i 's/a.com:8443/dockerhub/redis:5.0.3/'"${image}"'/g;s/8001/'"${sentinel_port}"'/g;' /usr/local/etc/redis/sentinel/docker-compose.yml

# start-all
chown -R polkitd:root /usr/local/etc/redis/
/usr/libexec/docker/cli-plugins/docker-compose -f /usr/local/etc/redis/docker-compose.yml up -d
/usr/libexec/docker/cli-plugins/docker-compose -f /usr/local/etc/redis/sentinel/docker-compose.yml up -d

4. 部署redis slave脚本

redis-slave-deploy.sh 文件内容如下：

代码语言：javascript复制
#!/bin/bash

if [ ! -n "$1" ] ;then
    echo "执行方式：redis-master-deploy.sh 镜像 redis起始端口号 master_ip，如 redis-master-deploy.sh a.com:8443/dockerhub/redis:5.0.3 7001 172.18.29.56"
    exit
fi

if [ ! -n "$2" ] ;then
    echo "执行方式：redis-master-deploy.sh 镜像 redis起始端口号 master_ip，如 redis-master-deploy.sh a.com:8443/dockerhub/redis:5.0.3 7001 172.18.29.56"
    exit
fi

if [ ! -n "$3" ] ;then
    echo "执行方式：redis-master-deploy.sh 镜像 redis起始端口号 master_ip，如 redis-master-deploy.sh a.com:8443/dockerhub/redis:5.0.3 7001 172.18.29.56"
    exit
fi

image=${1////\/}
port=$2
len=${#port}

for ((var=0; var<$len; var  ))
do
   a=${port:$var:1}
   if [ $var -eq 0 ]; then
     sentinel_port=$(($a 1))
   elif [ $var -eq $(($len-1)) ]; then
     sentinel_port=${sentinel_port}1
   else
     sentinel_port=${sentinel_port}0
   fi
done

# redis-server
for i in {1..16}
do
  old_port=$((7000 $i))
  new_port=$(($port   $i -1))
  sed_para=$sed_para"s/${old_port}/${new_port}/g;"
  mkdir -p /usr/local/etc/redis/redis$i/
  cp -f ~/redis.conf.template /usr/local/etc/redis/redis$i/redis.conf
  sed -i 's/7001/'"${new_port}"'/g;s/redis1/redis'"${i}"'/g;' /usr/local/etc/redis/redis$i/redis.conf
done

cp -f ~/docker-compose-server.yml.template /usr/local/etc/redis/docker-compose.yml
sed -e ${sed_para} -i /usr/local/etc/redis/docker-compose.yml
sed -i 's/a.com:8443/dockerhub/redis:5.0.3/'"${image}"'/g;s/172.18.29.56/'"$3"'/g;' /usr/local/etc/redis/docker-compose.yml

# sentinel

cp -f ~/sentinel.conf.template /usr/local/etc/redis/sentinel/sentinel.conf
# ip=`hostname -I | awk '{print $1}'`

6. 部署redis

代码语言：javascript复制
# 在 redis master 机器执行
./redis-master-deploy.sh 0f88f9be5839 20001

# 在 redis slave 机器执行
./redis-slave-deploy.sh 0f88f9be5839 20001 172.18.3.15

说明：

  1. 一次创建16组redis一主两从实例
  2. 需要模板文件 /root/*.template
  3. image、port为redis-master-deploy.sh命令行参数；image、port、master_ip为redis-slave-deploy.sh命令行参数；
  4. port为16个redis-server示例的起始端口，例如：port为7001将创建 7001 - 7016 16个实例
  5. 先部署master，再部署slave，主从port参数必须相同，本例同为7001
  6. 哨兵端口位数与port参数相同，定义为：第一位为port的第一位加1，最后一位为1，中间位数为0。例如port 参数值为 20010，则哨兵端口为30001；port 参数值为 7001，则哨兵端口为8001。

7. 基本维护
