本文收集并整理了Redis集群搭建的网文、网站、本身的经验。水平有限,只分享环境搭建。本文分为如下几个部分:html
请你们按照以上步骤来查看此文node
说明:linux
wget http://download.redis.io/releases/redis-4.0.10.tar.gz tar xzf redis-4.0.10.tar.gz cd redis-4.0.10 make PREFIX=/usr/local/redis install
注:若是不想将Redis做为一个服务,到这就已经安装完了redis
Create a directory where to store your Redis config files and your data:(有道词典:建立一个目录来存储Redis配置文件和数据:)shell
# 这只是一个目录结构,你们不要着急为何本身没有,往下看,一步一步来 [root@amor ~]# cd /usr/local/redis [root@amor redis]# tree . ├── bin # 编译安装指定目录后自动生成目录及文件 │ ├── redis-benchmark │ ├── redis-check-aof │ ├── redis-check-rdb │ ├── redis-cli │ ├── redis-sentinel -> redis-server │ └── redis-server ├── conf # 本身创建的存储配置文件的目录及本身建立的单个Redis配置文件 │ └── 6379.conf └── data # 本身创建的存储Redis数据的目录及单个Redis服务数据存储目录 └── 6379 4 directories, 7 files
注意:cp /usr/src/redis-4.0.10/src/redis-trib.rb /usr/local/redis/bin/
后面建立集群要用到ubuntu
Copy the init script that you'll find in the Redis distribution under the utils directory into /etc/init.d. We suggest calling it with the name of the port where you are running this instance of Redis. For example:(有道词典:将在utils目录下的Redis发行版中找到的init脚本复制到/etc/init.d中咱们建议使用正在运行这个Redis实例的端口的名称来调用它。例如:)vim
sudo cp utils/redis_init_script /etc/init.d/redis_6379
Edit the init script.(有道词典:编辑init脚本。)centos
#!/bin/sh # chkconfig 2345 90 25 # linux 开机启动设置 2345 运行级别 90 启动优先级(参考 memcached head /etc/rc.d/rc3.d/S90memcached ) 25 关闭优先级 (参考memcached) # Simple Redis init.d script conceived to work on Linux systems # as it does use of the /proc filesystem. ### BEGIN INIT INFO # Provides: redis_6379 # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Redis data structure server # Description: Redis data structure server. See https://redis.io ### END INIT INFO REDISPORT=6379 EXEC=/usr/local/redis/bin/redis-server # 修改成本身的可执行文件所在目录 CLIEXEC=/usr/local/redis/bin/redis-cli # 修改成本身的可执行文件所在目录 PIDFILE=/var/run/redis_${REDISPORT}.pid # 默认就好 CONF="/usr/local/redis/conf/${REDISPORT}.conf" # 修改成本身的配置文件存放目录 ···省略··· esac
开始修改redis.confapi
Make sure to modify REDISPORT accordingly to the port you are using. Both the pid file path and the configuration file name depend on the port number.(有道词典:请确保根据您正在使用的端口对从新分配进行相应的修改。pid文件路径和配置文件名都取决于端口号。)安全
sudo cp redis.conf /usr/local/redis/conf/6379.conf
(修改为本身定义的目录。参考上述目录结构 redis.conf 在大家redis解压目录中的src目录下)sudo mkdir /usr/local/redis/data/6379
(修改为本身定义的目录。参考上述目录结构)Edit the configuration file, making sure to perform the following changes:(有道词典:编辑配置文件,确保执行如下更改:)
注:上面的意思是让大家修改 /usr/local/redis/conf/6379.conf,用vim 打开,搜索上述关键词便可,参考如下设置(若是全部的步骤都是粘贴复制的走下来的,直接修改为下面这样:0.0):
port 6379 daemonize yes pidfile /var/run/redis_6379.pid loglevel notice logfile "/var/log/redis_6379.log" dir /usr/local/redis/data/6379
Finally add the new Redis init script to all the default runlevels using the following command:(有道词典:最后,使用如下命令将新的Redis init脚本添加到全部默认的运行级别:)
# ubuntu sudo update-rc.d redis_6379 defaults
# centos chkconfig --add redis_6379
You are done! Now you can try running your instance with:
sudo /etc/init.d/redis_6379 start
sudo /etc/init.d/redis_6379 start /usr/local/redis/bin/redis-server redis.conf # 注意此处缺省:配置文件路径 redis-cli -h 127.0.0.1 -p 6379 shutdown
注:若是只是中止本地redis 请执行: redis-cli shutdown
kill -9 进程号
pkill redis

注:下面的内容是我本身参考这篇博文加上我熟悉Redis安装后本身的配置过程。你们能够参考NrwLm - Redis 集群搭建详细指南。
cd /usr/local/redis/conf cp 6379.conf redis.conf.default # 用做集群其余配置文件的蓝本 sudo vim redis.conf.default
修改内容以下
bind 192.168.2.123 # 绑定当前机器 IP cluster-enabled yes # 取消注释,启动集群模式 cluster-config-file nodes-6379.conf # 取消注释,修改成 /usr/local/redis/data/6379/nodes-6379.conf (若是遇到须要从新创建集群,不将此项修改成指定路径而和启动配置文件放在一块儿,会致使创建集群时,删除重建conf 文件) cluster-node-timeout 15000 # 取消注释 appendonly yes # 将 no 修改成 yes
cd /usr/local/redis/conf echo 9001.conf 9002.conf 9003.conf 9004.conf 9005.conf 9006.conf | xargs -n 1 cp -v redis.conf.default sed -i 's/6379/9001/g' 9001.conf sed -i 's/6379/9002/g' 9002.conf sed -i 's/6379/9003/g' 9003.conf sed -i 's/6379/9004/g' 9004.conf sed -i 's/6379/9005/g' 9005.conf sed -i 's/6379/9006/g' 9006.conf
cd /usr/local/redis/data mkdir -p 9001 9002 9003 9004 9005 9006 # 后期可能须要删除该文件件下的文件,用于重建集群,因此,删除命令也写一下 rm -rf 900*/*

执行命令: /usr/local/redis/bin/redis-cli -c -h 192.168.2.123 -p 9001
redis /usr/bin/env: ruby: 没有那个文件或目录
rvm get stable --auto-dotfiles
,或者执行 nvm list
有详细的错误说明(查了资料说,线上不要用rvm安装ruby)这是我本身的解决方案
# 把这个添加到 /etc/profile 文件中(放到最后就行) rvm use ruby-2.6.0-preview2
