Linux安装Redis 4.0.14组建集群时报错处理

一、问题描述

在某次IPv6改造过程中，因Redis现场版本实际使用3.0.4，并不支持ipv6，需升级到Redis 4.0.14（4.0版本的最新版），然后在部署过程中报错：

internal:/usr/local/lib/ruby/3.0.0/rubygems/core_ext/kernel_require.rb>:85:in `require': /usr/local/lib/ruby/site_ruby/3.0.0/x86_64-linux/zlib.so: undefined symbol: inflateReset - /usr/local/lib/ruby/site_ruby/3.0.0/x86_64-linux/zlib.so (LoadError)

	from /usr/local/bin/gem:21:in `<main>'

二、原因分析及处理

1、上述报错是在执行如下命令时报错的：

gem install -l ./redis-4.2.1.gem #本地安装Redis gem包

在这里插入图片描述

2、现场验证是因为zlib的库文件，so文件所致，执行如下：

ruby --version
ruby 3.0.0p0 (2020-12-25 revision 95aff21468) [x86_64-linux]

yum install zlib-devel -y
yum list installed|grep zlib
zlib.x86_64                           1.2.7-18.el7                    @centos7u3
zlib-devel.x86_64                     1.2.7-18.el7     
cd /home/software/ruby-3.0.0/ext/zlib
make&make install

#之后再执行安装
gem install -l ./redis-4.2.1.gem  //输出如下
Successfully installed redis-4.2.1
Parsing documentation for redis-4.2.1
Installing ri documentation for redis-4.2.1
Done installing documentation for redis after 0 seconds
1 gem installed

三、Redis-Cluster集群部署

#ruby环境
yum install -y ruby  //默认安装的，安装redis时会提示版本低，需下载高版本的重新编译
yum install rubygems

#安装基础环境
yum install gcc* gcc++*  -y
#对应clang安装对gcc，g++，cmake等有版本要求，尽量安装版本不要太低，软件地址：http://llvm.org/releases/download.html，redis此处可不安装
# ruby编译安装
./configure 
make && make install
#验证：
ruby --version
ruby 3.0.0p0 (2020-12-25 revision 95aff21468) [x86_64-linux]

#安装zlib库文件
cd ext/zlib/
./bin/ruby ./extconf.rb
make
make install
#
gem install -l ./redis-4.2.1.gem

在这里插入图片描述
1）启动Redis集群实例：

cd /home/software/redis/redis-4.0.14
make //编译后会再src下生产redismingl
#编辑redis实例文件，之后启动，注意，集群的配置文件node_xxx.conf是redis启动后监测到集群模式自动生成的，无需手动创建，如果配置文件写错，会报如下错误，如上图所示：
Can't open /usr/local/redis/redis-4.0.14/nodes_7000.conf in order to acquire a lock: No such file or directory

#启动实例
