[email protected] soft]# gem install redis-4.0.0.gem ERROR:  Loading command: install (LoadError) cannot load such file -- zlibERROR:  While executing gem ... (NoMethodError)    undefined method `invoke_with_build_args' for nil:NilClass解決辦法是：

1. 進入ruby原始碼資料夾

1. 安裝ruby自身提供的zlib包

#cd ext/zlib#ruby ./extconf.rb#make#make install問題一：問題：/soft/redis-4.0.8/src/redis-trib.rb create --replicas 1 node1:7000 node1:7001 node2:7002  node2:7003  node3:7004 node3:7005/usr/local/ruby/lib/ruby/2.4.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- redis (LoadError) from /usr/local/ruby/lib/ruby/2.4.0/rubygems/core_ext/kernel_require.rb:55:in `require' from /soft/redis-4.0.8/src/redis-trib.rb:25:in `<main>解決辦法：Ruby的redis介面沒有安裝，需要安裝Redis介面，輸入命令 " gem install redis " 進行安裝，如下圖：今天yum install的時候出問題了,找了半天才找到一個可行的解決辦法fastestmirror是yum的一個加速外掛，這裡是外掛提示資訊是外掛不能用了。不能用就先別用唄，禁用掉，先yum了再說。1.修改外掛的配置檔案# vi  /etc/yum/pluginconf.d/fastestmirror.conf  enabled = 1//由1改為0，禁用該外掛...............................2.修改yum的配置檔案# vi /etc/yum.conf.........................plugins=1//改為0，不使用外掛........................清理 刪除yumyum cleanyum update第一步：安裝gcc 、zlib-devel 庫注：由於安裝系統的時候沒有裝c編譯器 導致很多原始碼安裝的程式無法編譯 所以需要在Linux上裝c編譯器，必須按順序安裝否則安裝不會成功 。yum -y install gcc gcc-c++ autoconf automake makeyum install zlib,zlib-devel第二步、 離線安裝perl5.看看perl的版本： perl -v首先下載最新的perl原始碼包： wget http://www.cpan.org/src/5.0/perl-5.16.1.tar.gz解壓原始碼包 tar -xvf  perl-5.16.1.tar.gz編譯並安裝,目錄可以自定義 cd perl-5.16.1 ./Configure -des -Dprefix=/usr/local/perl make make test make install第三步、我們又得安裝OpenSSL才行，1 $ tar -xzvf openssl-1.0.2l.tar.gz
2 $ cd openssl-1.0.2l
3 $ ./config -fPIC --prefix=/usr/local/openssl enable-shared
4 $ ./config -t
5 $ make && make installopenssl version -a列印版本資訊表示成功，出現問題，安裝有問題，參考 第四步、離線安裝高版本的ruby2.5 tar -xvf ruby-2.5.0.tar.gz $ ./configure --prefix=/usr/local/ruby -prefix是將ruby安裝到指定目錄，也可以自定義
2 $ make && make installln -s /usr/local/ruby/bin/ruby /usr/bin/rubycd /soft/ruby-2.5.0/ext/openssl       備註：/soft/ruby-2.5.0這個目錄是ruby安裝包後解壓的目錄，就是前面提到的ruby離線安裝$ruby extconf.rb  --with-openssl-include=/usr/local/openssl/include/ --with-openssl-lib=/usr/local/openssl/lib //會生成一個Makefile檔案 問題：extconf.rb:94:in `<main>': OpenSSL library could not be found. You might want to use --with-openssl-dir=<dir> option to specify the prefix where OpenSSL is installed. (RuntimeError)解決辦法：修改Make檔案的變數  top_srcdir=../.. ，openssl沒安裝成功的原因，備註：開始下載的是openssl-fips-2.0.16.tar.gz，後面改成1.1.0g.tar.gz 。在當前目錄下要執行此命令$ make && make install 注意：make: *** No rule to make target `/usr/include/ruby/backward.h', needed by `ossl_pkey_ec.o'.  Stop.（搞的很糾結，重新安裝ruby)$gem install redis Unable to require openssl, install OpenSSL and rebuild ruby (preferred) or use non-HTTPS sources Unable to require openssl, install OpenSSL and rebuild Ruby (preferred) or use non-HTTPS sources說明Ruby對應的openssl沒安裝成功啟動有錯誤：ERR Invalid node address specified: node1:7000 (Redis::CommandError)openssl: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory這是由於openssl庫的位置不正確造成的。解決方法：在root使用者下執行：ln -s /usr/local/lib64/libssl.so.1.1 /usr/lib64/libssl.so.1.1
ln -s /usr/local/lib64/libcrypto.so.1.1 /usr/lib64/libcrypto.so.1.1先安裝openssl ,然後在安裝ruby, 在ruby的ext目錄下進行再安裝。遇到問題了，處理方式參考，/soft/redis-4.0.8/src/redis-trib.rb create --replicas 1 192.168.2.11:7000 192.168.2.11:7001 192.168.2.12:7002  192.168.2.12:7003  192.168.2.13:7004 192.168.2.13:7005cat /etc/sysctl.confvi /etc/sysctl.conf增加下面的內容vm.overcommit_memory = 1net.core.somaxconn = 2048sysctl -pvi /etc/rc.localecho never > /sys/kernel/mm/transparent_hugepage/enabledecho never > /sys/kernel/mm/transparent_hugepage/defragchmod +x /etc/rc.d/rc.localredis.confport  7000                                bind 192.168.2.11                             daemonize    yes                          pidfile  /var/run/redis_7000.pid        cluster-enabled  yes                     cluster-config-file  /usr/local/redis/redis_cluster/nodes_7000.conf      cluster-node-timeout  15000               dir /usr/local/redis/redis_cluster/7000/datalogfile /usr/local/redis/redis_cluster/7000/redis.log   appendonly  yes
