Docker 部署 Redis 集群 VS 正常部署 Redis 集群
阅读本文大概需要 4 分钟。
前言
yum -y install wget
安装。wget http://download.redis.io/releases/redis-6.0.7.tar.gz
yum -y install gcc-c++
tar xzf redis-6.0.7.tar.gz
cd redis-6.0.7
make
# 1、安装gcc全家桶
yum install cpp
yum install binutils
yum install glibc
yum install glibc-kernheaders
yum install glibc-common
yum install glibc-devel
yum install gcc
yum install make
# 2、升级gcc
yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
scl enable devtoolset-9 bash
# 3、设置永久生效
echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile
make install
redis-server redis.conf
# 通过脚本创建6个redis配置
for port in $(seq 1 6); \
do \
mkdir -p /root/redis/node-${port}/conf
touch /root/redis/node-${port}/conf/redis.conf
cat << EOF >/root/redis/node-${port}/conf/redis.conf
port 637${port}
bind 0.0.0.0
cluster-enabled yes
cluster-config-file /root/redis/node-${port}/conf/nodes.conf
cluster-node-timeout 5000
appendonly yes
daemonize yes
EOF
done
for port in $(seq 1 6); \
do \
redis-server /root/redis/node-${port}/conf/redis.conf
done
redis-cli --cluster create 127.0.0.1:6371 127.0.0.1:6372 127.0.0.1:6373 127.0.0.1:6374 127.0.0.1:6375 127.0.0.1:6376 --cluster-replicas 1
#1、卸载旧的版本
sudo yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine
#2、需要的安装包
sudo yum install -y yum-utils
#3、安装镜像仓库
sudo yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo # 默认是国外的
sudo yum-config-manager \
--add-repo \
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo # 建议使用阿里云的,十分快速
# 配置下加速
# >移动到下述目录:
cd /etc/docker
# >找到daemon.json文件,如果没有就新建一个,填入如下信息:
["https://almtd3fa.mirror.aliyuncs.com"]} :
# >重启下docker
service docker restart
# 更新yum软件包索引
yum makecache fast
#4、安装docker相关的依赖 docker-ce 社区版 ee 企业版
sudo yum install docker-ce docker-ce-cli containerd.io
#5、启动Docker
sudo systemctl start docker
#6、检测是否安装成功
docker version
#7、测试hello-world
docker run hello-world
#8、查看一下下载的这个 hello-world 镜像
~]# docker images

搞定,收工!!
别忘记点个再看,咱们下篇见!
每天进步一点点
慢一点才能更快

为什么 Java 中“1000==1000”为false,而”100==100“为true?
