tar -xvf ruby-2.4.4.tar.gz

cd ruby-2.4.4

./configure –prefix=/usr/local/ruby

echo $

make && make install

echo "PATH=$PATH:/usr/local/ruby/bin" >> /etc/profile

source /etc/profile

which ruby

/usr/bin/ruby

rm -rf /usr/bin/ruby

ln -s /usr/local/ruby/bin/ruby /usr/bin/ruby

[root@localhost ruby-2.4.4]# ruby -v

ruby 2.4.4p296 (2018-03-28 revision 63013) [x86_64-linux]

離線安裝rubygems

https://rubygems.org/rubygems/rubygems-2.7.6.tgz

tar -xvf rubygems-2.7.6.tgz

chown -R root.root rubygems-2.7.6

mv rubygems-2.7.6 /usr/local/

cd /usr/local/rubygems-2.7.6/

ruby setup.rb

echo "PATH=$PATH:/usr/local/rubygems-2.7.6" >> /etc/profile

source /etc/profile

查看當(dāng)前版本

[root@localhost tools]# gem -v

2.7.6

——————————————————————————————————————-

離線配置rubygems的redisapi

下載redis的gem并上傳至服務(wù)器

https://rubygems.org/downloads/redis-3.3.0.gem

下載新的版本

https://rubygems.org/downloads/redis-4.0.2.gem

gem install -l redis-3.3.0.gem

[root@localhost tools]# gem list redis

*** LOCAL GEMS ***

redis (3.3.0)

如果安裝是舊的版本

卸載

gem uninstal redis

安裝

gem install -l redis-4.0.2.gem

[root@localhost tools]# gem list redis

*** LOCAL GEMS ***

redis (4.0.2)

——————————————————————————————————————-

離線安裝tcl

下載tcl8并上傳至服務(wù)器

https://sourceforge.net/projects/tcl/files/Tcl/8.6.0/

unzip tcl868-src.zip

cd tcl8.6.8/unix/

./configure –prefix=/usr/local/tcl

echo $

make install-private-headers

ln -v -sf tclsh8.6 /usr/local/tcl/bin/tclsh

chmod -v 755 /usr/local/tcl/lib/libtcl8.6.so

echo "PATH=$PATH:/usr/local/tcl/bin" >> /etc/profile

source /etc/profile

創(chuàng)建用戶

useradd qasuser

echo devops | passwd –stdin qasuser

下載redis安裝包

http://download.redis.io/releases/redis-4.0.11.tar.gz

安裝及配置

tar -xvf redis-4.0.11.tar.gz -C /app

chown -R qasuser.qasuser /app/redis-4.0.11

cd /app/redis-4.0.11

———————————————————————————————————————–

如果因?yàn)樯洗尉幾g失敗，有殘留的文件，做法如下：

[qasuser@localhost redis-4.0.11]$make distclean

———————————————————————————————————————–

[qasuser@localhost redis-4.0.11]$ make

redis.conf的配置說明：

port 7000 配置集群的端口，分別第一組7000、7001、7002，第一組7003、7004、7005，第一組7006、7007、7008

bind 本機(jī)的IP 這里的默認(rèn)配置是127.0.0.1改為內(nèi)網(wǎng)ip。

daemonsize yes 允許redis在后臺(tái)運(yùn)行

pidfile /var/run/redis_7000.pid 改成和端口一致

cluster-enabled yes 開啟集群把注釋去掉

cluster-config-file node_7000.conf 集群的配置，和端口一致

cluster-node-timeout 15000 請(qǐng)求超時(shí)，默認(rèn)為15秒

appendonly yes aof日志開啟，有需要就開啟，每一次寫操作都會(huì)記錄一條日志。

關(guān)閉集群

推薦做法：

[qasuser@localhost redis-cluster]$ pkill redis

或者循環(huán)節(jié)點(diǎn)逐個(gè)關(guān)閉

[qasuser@localhost redis-cluster]$ for((i=0;i<=2;i++)); do /app/redis-4.0.11/src/redis-cli -c -h 172.16.8.13 -p 700$i shutdown; done

[qasuser@localhost redis-cluster]$ for((i=3;i<=5;i++)); do /app/redis-4.0.11/src/redis-cli -c -h 172.16.8.14 -p 700$i shutdown; done

[qasuser@localhost redis-cluster]$ for((i=6;i<=8;i++)); do /app/redis-4.0.11/src/redis-cli -c -h 172.16.8.15 -p 700$i shutdown; done

問題解決：

/usr/local/ruby/lib/ruby/gems/2.4.0/gems/redis-3.3.0/lib/redis/client.rb:459: warning: constant ::Fixnum is deprecated

是因?yàn)?版本過低導(dǎo)致 gem 升級(jí)redis-4.0.2.gem

步驟如下：

gem uninstal redis

gem install -l redis-4.0.2.gem
