redis集群 安装报错总结

ruby 编译安装

wget https://cache.ruby-lang.org/pub/ruby/2.5/ruby-2.5.0.tar.gz
tar zxf ruby-2.5.0.tar.gz
cd ruby-2.5.0
./configure --prefix=/usr/local/ruby
make
make install

执行 ./redis-trib.rb 报错

Traceback (most recent call last):
    2: from /usr/local/bin/redis-trib.rb:25:in `<main>'
    1: from /usr/local/ruby/lib/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in `require'
/usr/local/ruby/lib/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in `require': cannot load such file -- redis (LoadError)

解决方法：

下载 安装ruby ，执行gem install redis来安装ruby执行redis相关依赖

gem install redis 报错

错误1 缺少zlib

ERROR:  Loading command: install (LoadError)
        cannot load such file -- zlib
ERROR:  While executing gem ... (NoMethodError)
    undefined method `invoke_with_build_args' for nil:NilClass

解决方法：

yum -y install zlib-devel
# 进入ruby源码包
cd ruby-2.5.0/ext/zlib
ruby ./extconf.rb
make

make报错

make: *** No rule to make target `/include/ruby.h', needed by `zlib.o'.  Stop.

解决方法：

修改 Makefile

将 zlib.o: $(top_srcdir)/include/ruby.h 中的 $(top_srcdir) 修改为../.. 或 在 Makefile 最开始给 top_srcdir赋值 top_srcdir = ../..

错误2 缺少openssl

ERROR:  While executing gem ... (Gem::Exception)
    Unable to require openssl, install OpenSSL and rebuild Ruby (preferred) or use non-HTTPS sources

解决方法：

yum -y install openssl-devel
# 进入ruby源码包
cd ruby-2.5.0/ext/openssl
ruby ./extconf.rb
make

make 报错

compiling openssl_missing.c
make: *** No rule to make target `/include/ruby.h', needed by `ossl.o'.  Stop.

解决方法：

修改 Makefile

同上，将 ${top_srcdir} 变量赋值top_srcdir = ../..

执行 ` redis-trib.rb create 报错ERR Slot 0 is already busy (Redis::CommandError)`

解决方法：

进入每个实例初始化cluster

redis-cli -h 10.211.55.6 -p 7000
master:7000> flushall
master:7000> cluster reset
