安装
源码安装
github地址redis-hashes 选择5.0的最新版本.5.0.14
单节点
# 1.下载安装包
wget http://download.redis.io/releases/redis-5.0.14.tar.gz
# 2.解压
tar -zxf redis-5.0.14.tar.gz
# 3.进入文件夹,可以查看readme.md来查看安装步骤与参数设置.
# make本质时读取makefile文件里的命令集,所以可以通过阅读具体的makefile来了解具体的安装细节.
# make install 本质是一个拷贝的步骤.
make
# 异常点:
make[1]: [persist-settings] Error 2 (ignored)
CC adlist.o
/bin/sh: cc: command not found
# 3.1安装gcc
yum install gcc
# 先清除之前出问题的安装文件 再执行make
make distclean & make
# 结果
Hint: It's a good idea to run 'make test' ;)
make[1]: Leaving directory `/root/redis-5.0.14/src'
# 安装完成后目录下会出现一个src文件夹.里面存有可执行脚本与配置.
# eg: ./redis-server 即redis启动命令.
# 4. 安装到配置的目录下.在编译的时候设置为/user/local/bin. 或者自己配置来覆盖PERFIX=/opt/redis/bin/
make install
# 结果:
[root@unreal-laser-1 redis-5.0.14]# cd /usr/local/bin/
caddy redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-sentinel redis-server
# 4.1 redis也提供了交互式安装在utils文件夹下, utils/install_server.sh
./install_server.sh
# 此方法会在/etc/init.d/下生成一个redis_前缀+端口的可执行文件,供快捷使用.通过这种方式可以快速的创建出大量的redis实例来组建集群.
# 执行例子
[root@unreal-laser-1 utils]# ./install_server.sh

# 6. 配置文件启动
# 在源目录中存在配置文件 redis.conf. 里面可以配置port端口,bind指定ip,protected-model模式,请求密码等配置.
# 可以将配置文件拷贝到指定文件夹下修改后, 启动服务带指定配置文件的方式启动.

主从复制版
1. 创建并启动实例(一主两从版)
[root@unreal-laser-1 utils]# ps -ef |grep redis

2. 进入从节点,关联主节点
[root@unreal-laser-1 utils]# redis-cli -p 6401
127.0.0.1:6401> help slaveof
SLAVEOF host port
summary: Make the server a replica of another instance, or promote it as master. Deprecated starting with Redis 5. Use REPLICAOF instead.

2.2. 修改配置文件来永久配置
# 主节点的ip:端口
replicaof <masterip> <masterport>
# 主节点的密码
masterauth
# 复制主节点信息时,服务是否对外提供旧的数据.
replica-serve-stale-data yes
# 从节点只读
replica-read-only yes
# 同步文件时直接通过网络还是先保存在磁盘再通过网络.

2.3 启动redis服务时就带上跟随节点
redis-cli /etc/redis/6401.conf --replicof 172.0.0.1 6400
3. 查看节点信息

docker 安装
docker 单节点
1. 拉取镜像
docker pull redis
2. 设置挂载目录
为防止容器被重建,需要本地化配置文件与日志.
1）、挂载redis的配置文件, liunx 下redis.conf文件位置： /data/redis/single/redis.conf
2）、挂载redis 的持久化文件（为了数据的持久化）, liunx 下redis的data文件位置 ： /data/redis/single/data
3. 启动容器并挂载文件夹
docker run --restart=always --log-opt max-size=100m --log-opt max-file=2 -p 6379:6379 --name myredis -v /data/redis/single/redis.conf:/etc/redis/redis.conf -v /data/redis/single/data:/data -d redis redis-server /etc/redis/redis.conf --appendonly yes --requirepass 1234qwer
- restart=always :开机自启
--log-opt :日志配置,大小100M,两个文件
--name myredis :容器名称
-v 数据挂载 : 将配置文件与数据挂载到实体机上.
-d redis :后台启动
--appendonly yes : 开启aof持久化日志.
--requirepass 1234qwer :配置redis密码
docker 集群安装
1. 创建实例

如有需要,则将网络定义为local.
