一、環境
三臺CentOS7.5服務器(每臺服務器兩個實例，以一臺服務器爲例，另外兩臺服務器配置相同，安裝相同)
192.168.10.176
192.168.10.177
192.168.10.178
二、集羣模式(cluster)
1、下載redis、ruby、rubygems二進制包，創建包存放目錄，解壓目錄。
mkdir /tools
mkdir /depend
cd /tools
wget http://download.redis.io/releases/redis-3.2.12.tar.gz
wget http://ftp.ruby-lang.org/pub/ruby/2.4/ruby-2.4.4.tar.gz
wget https://rubygems.org/rubygems/rubygems-2.7.7.tgz
wget https://rubygems.org/downloads/redis-3.2.0.gem
tar xzf redis-3.2.12.tar.gz -C /depend/
tar xzf ruby-2.4.4.tar.gz -C /depend/
tar xzf rubygems-2.7.7.tgz -C /depend/
2、安裝redis和ruby同時加入環境變量
cd /depend/redis-3.2.12/
make -j 8 && make install PREFIX=/opt/redis
cd ../ruby-2.4.4/
./configure --prefix=/opt/ruby
make -j 8 && make install
echo "# redis" >> /etc/profile
echo "export HOME=/opt/redis/bin" >> /etc/profile
echo "export PATH=$PATH:$HOME" >> /etc/profile
echo "# ruby" >> /etc/profile
echo "export HOME=/opt/ruby/bin" >> /etc/profile
echo "export PATH=$PATH:$HOME" >> /etc/profile
source /etc/profile
3、安裝rubygems
[root@localhost ruby-2.4.4]# cd /tools
[root@localhost tools]# gem install redis-3.2.0.gem
ERROR: Loading command: install (LoadError)
cannot load such file -- zlib
ERROR: While executing gem ... (NoMethodError)
undefined method `invoke_with_build_args' for nil:NilClass
4、安裝失敗，這是需要依賴zlib工具才能安裝，下載zlib工具，解壓安裝。
[root@localhost rubygems-2.7.7]# cd /tools/
[root@localhost tools]# wget http://www.zlib.net/zlib-1.2.11.tar.gz
[root@localhost tools]# tar xzf zlib-1.2.11.tar.gz -C /depend/
[root@localhost tools]# cd /depend/zlib-1.2.11/
# 編譯和安裝過程省略
[root@localhost zlib-1.2.11]# ./configure --prefix=/usr/local/zlib
[root@localhost zlib-1.2.11]# make -j 8 && make install
5、安裝完成後執行以下命令,安裝zlib
[root@localhost ruby-2.4.4]# cd /depend/ruby-2.4.4/ext/zlib/
[root@localhost zlib]# ruby extconf.rb --with-zlib-include=/usr/local/zlib/include/ --with-zlib-lib=/usr/local/zlib/lib
[root@localhost zlib]# make -j 8 && make install
make: *** No rule to make target `/include/ruby.h', needed by `zlib.o'. Stop.
6、安裝zlib報錯，修改Makefile文件中：zlib.o: $(top_srcdir)/include/ruby.h 改成：zlib.o: …/…/include/ruby.h
vi Makefile
zlib.o: ../../include/ruby.h
7、繼續執行make -j 8 && make install
[root@localhost zlib]# make -j 8 && make install
compiling zlib.c
linking shared-object zlib.so
/usr/bin/install -c -m 0755 zlib.so /opt/ruby/lib/ruby/site_ruby/2.4.0/x86_64-linux
8、回到gem目錄下，繼續安裝redis-3.2.0.gem
[root@localhost tools]# gem install redis-3.2.
[root@localhost tools]# gem install redis-3.2.0.gem
ERROR: While executing gem ... (Gem::Exception)
Unable to require openssl, install OpenSSL and rebuild Ruby (preferred) or use non-HTTPS sources
9、安裝報錯，需要依賴OpenSSL，繼續下載openssl安裝。
wget https://www.openssl.org/source/old/1.0.2/openssl-1.0.2l.tar.gz
tar xzf openssl-1.0.2l.tar.gz-C /depend
cd /depend/openssl-1.0.2l
./config -fPIC --prefix=/usr/local/openssl enable-shared
Operating system: x86_64-whatever-linux2
You need Perl 5
10、編譯失敗，需要perl工具，下載安裝perl工具，在安裝OpenSSL。
cd /tools
wget https://www.cpan.org/src/5.0/perl-5.28.0.tar.gz
tar xzf perl-5.28.0.tar.gz -C /depend/
cd /depend/perl-5.28.0/
./Configure -des -Dprefix=/usr/local/localperl
make -j 8 && make install
cd /depend/openssl-1.0.2l
./config -fPIC --prefix=/usr/local/openssl enable-shared
./config -t
make -j 8 && make install
11、安裝完成後跟zlib一樣執行以下命令
cd ../ruby-2.4.4/ext/openssl/
ruby extconf.rb --with-openssl-include=/usr/local/openssl/include/ --with-openssl-lib=/usr/local/openssl/lib
[root@localhost openssl]# make -j 8 && make install
compiling openssl_missing.c
make: *** No rule to make target `/include/ruby.h', needed by `ossl.o'. Stop.
make: *** Waiting for unfinished jobs....
12、安裝報錯，跟zlib一樣的類似錯誤，修改Makefile文件中：將全部$(top_srcdir)全部替換成…/…
vi Makefile
# 執行以下命令替換所有
:%s/\$(top_srcdir)/\.\.\/\.\./g
13、繼續執行make -j 8 && make install
make -j 8 && make install
14、回到gem目錄下，繼續安裝redis-3.2.0.gem
[root@localhost openssl]# cd /tools/
[root@localhost tools]# gem install redis-3.2.0.gem
Successfully installed redis-3.2.0
Parsing documentation for redis-3.2.0
Installing ri documentation for redis-3.2.0
Done installing documentation for redis after 1 seconds
1 gem installed
15、安裝成功，創建目錄拷貝配置文件。
[root@localhost conf]# mkdir -pv /opt/redis/data/6379
[root@localhost conf]# mkdir -pv /opt/redis/data/6479
[root@localhost conf]# mkdir /opt/redis/logs
[root@localhost conf]# mkdir /opt/redis/conf
[root@localhost conf]# mkdir /opt/redis/pid
[root@localhost conf]# mkdir /opt/redis/scripts
# 回到解壓目錄拷貝redis.conf配置文件
[root@localhost redis-3.2.12]# cp redis.conf /opt/redis/conf/
[root@localhost redis-3.2.12]# cd /opt/redis/conf/
[root@localhost conf]# mv redis.conf redis-6379.conf

16、啓動並查看redis
nohup redis-server conf/redis-6379.conf
nohup redis-server conf/redis-6479.conf
ps aux | grep redis
root 10476 0.0 0.0 141072 7576 ? Ssl 14:56 0:01 redis-server 192.168.10.177:6379 [cluster]
root 10525 0.0 0.0 136976 7556 ? Ssl 14:57 0:01 redis-server 192.168.10.177:6479 [cluster]
root 11483 0.0 0.0 112708 984 pts/0 S+ 15:16 0:00 grep --color=auto redis
17、啓動集羣設置密碼及驗證集羣
redis-trib.rb create --replicas 1 192.168.10.176:6379 192.168.10.176:6479 192.168.10.177:6379 192.168.10.177:6479 192.168.10.178:6379 192.168.10.178:6479
啓動成功後設置密碼
redis-cli -c -h 192.168.10.176 -p 6379
config set masterauth test@123
config set requirepass test@123
auth test@123
config rewrite
驗證集羣
刪除單個url換成
redis-cli -c -h 192.168.10.176 -p 6379
auth passwd
get portal:perm:url:cache:10013
del portal:perm:url:cache:10013
查看所有key值:keys *
刪除指定索引的值:del key
清空整個 Redis 服務器的數據:flushall
清空當前庫中的所有 key:flushdb
18、啓動和關閉redis腳本
啓動腳本
[root@localhost scripts]# cat start.sh
#!/bin/bash
read -p "plese [6379|6479|all]: " redis
if [ $redis = 6379 ];then
nohup redis-server /opt/redis/conf/redis-6379.conf

fi
if [ $redis = all ];then
nohup redis-server /opt/redis/conf/redis-6379.conf
