1.下载安装介质
我这里下载的是redis-5.0.14.tar.gz
下载地址:
http://download.redis.io/releases/
2.解压介质并安装
[root@localhost soft]# tar -xvf redis-5.0.14.tar.gz
[root@localhost soft]# cd redis-5.0.14
[root@node1 redis-5.0.14]# make
[root@node1 redis-5.0.14]# make test
没有问题的话，会输入如下信息
\o/ All tests passed without errors!
Cleanup: may take some time... OK
make[1]: Leaving directory `/soft/redis-5.0.14/src'
[root@node1 redis-5.0.14]#
安装到指定的目录,默认是安装在/usr/bin目录,我们这里统一安装到/usr/local/services/redis目录,该目录不用提前创建
[root@node1 redis-5.0.14]# cd src
[root@node1 src]# make PREFIX=/usr/local/services/redis install
Hint: It's a good idea to run 'make test' ;)
INSTALL install
INSTALL install
INSTALL install
INSTALL install
INSTALL install
拷贝 ./scr/redis-trib.rb到指定的目录,该脚本是用来创建集群用的
[root@node1 src]# cp redis-trib.rb /usr/local/services/redis/
3.创建目录并修改相应权限
[root@localhost src]# mkdir -p /home/middle/redis/conf
[root@localhost src]# mkdir -p /home/middle/redis/data
[root@localhost src]# mkdir -p /home/middle/redis/logs
[root@localhost src]# mkdir -p /home/middle/redis/run
创建数据目录
[root@localhost src]#mkdir -p /home/middle/redis/data/redis_7001
[root@localhost src]#mkdir -p /home/middle/redis/data/redis_7002
[root@localhost src]#mkdir -p /home/middle/redis/data/redis_7003
[root@localhost src]#mkdir -p /home/middle/redis/data/redis_7004
[root@localhost src]#mkdir -p /home/middle/redis/data/redis_7005
[root@localhost src]#mkdir -p /home/middle/redis/data/redis_7006
4.创建配置文件
vi /home/middle/redis/conf/7001.conf
内如如下:

密码先注释掉,等创建了集群后再启用
拷贝 7001.conf 生成 7002.conf 配置文件
cd /home/middle/redis/conf
cp 7001.conf 7002.conf
cp 7001.conf 7003.conf
cp 7001.conf 7004.conf
cp 7001.conf 7005.conf
cp 7001.conf 7006.conf
替换修改配置文件的内容
sed -i 's/7001/7002/g' /home/middle/redis/conf/7002.conf
sed -i 's/7001/7003/g' /home/middle/redis/conf/7003.conf
sed -i 's/7001/7004/g' /home/middle/redis/conf/7004.conf

----------------------------配置集群-------------------------------------
1.创建集群
[root@node1 conf]# /usr/local/services/redis/redis-trib.rb create --replicas 1 192.168.1.105:7001 192.168.1.105:7002 192.168.1.105:7003 192.168.1.105:7004 192.168.1.105:7005 192.168.1.105:7006
/usr/bin/env: ruby: No such file or directory
解决办法:
需要安装ruby
https://www.cnblogs.com/hxlasky/p/14734140.html
再次报错:
[root@node1 ~]# /usr/local/services/redis/redis-trib.rb create --replicas 1 192.168.1.105:7001 192.168.1.105:7002 192.168.1.105:7003 192.168.1.105:7004 192.168.1.105:7005 192.168.1.105:7006
WARNING: redis-trib.rb is not longer available!
You should use redis-cli instead.All commands and features belonging to redis-trib.rb have been moved
to redis-cli.
In order to use them you should call redis-cli with the --cluster
option followed by the subcommand name, arguments and options.Use the following syntax:
redis-cli --cluster SUBCOMMAND [ARGUMENTS] [OPTIONS]Example:
redis-cli --cluster create 192.168.1.105:7001 192.168.1.105:7002 192.168.1.105:7003 192.168.1.105:7004 192.168.1.105:7005 192.168.1.105:7006 --cluster-replicas 1To get help about all subcommands, type:
redis-cli --cluster help
发现5.0版本不需要使用redis-trib.rb创建集群了，改用redis-cli --cluster create创建集群了
/usr/local/services/redis/bin/redis-cli --cluster create 192.168.1.105:7001 192.168.1.105:7002 192.168.1.105:7003 192.168.1.105:7004 192.168.1.105:7005 192.168.1.105:7006 --cluster-replicas 1

2.启用密码
停掉每个节点,修改配置文件,启用密码认证
/usr/local/services/redis/bin/redis-cli -h 192.168.1.105 -p 7001 shutdown
/usr/local/services/redis/bin/redis-cli -h 192.168.1.105 -p 7002 shutdown
/usr/local/services/redis/bin/redis-cli -h 192.168.1.105 -p 7003 shutdown
/usr/local/services/redis/bin/redis-cli -h 192.168.1.105 -p 7004 shutdown
/usr/local/services/redis/bin/redis-cli -h 192.168.1.105 -p 7005 shutdown
/usr/local/services/redis/bin/redis-cli -h 192.168.1.105 -p 7006 shutdown
修改配置文件
vi /home/middle/redis/conf/7001.conf
vi /home/middle/redis/conf/7002.conf
vi /home/middle/redis/conf/7003.conf
vi /home/middle/redis/conf/7004.conf
vi /home/middle/redis/conf/7005.conf
vi /home/middle/redis/conf/7006.conf
修改每个节点的配置文件,把每个节点的配置文件如下两项先注释掉
##masterauth "自己设定的密码"
##requirepass "自己设定的密码"
再次启动
/usr/local/services/redis/bin/redis-server /home/middle/redis/conf/7001.conf
