RedHat6.5虚拟机架设Redis和Kafka伪集群

时间：2021-02-20 17:10:46

架设Redis:

虚拟机架设，桥接模式下要保证实体机能上网，这样虚拟机才会分配到一个ip(这里是192.168.43.105),方便下面的集群配置每个节点ip,伪集群都设置成一个，

但要保证这个ip网络畅通，cluster的各个节点才可按照该ip彼此访问.


普通用户xiaobai,copy Redis.tar文件，解压到/usr/local失败：


Linux怎么在文件系统/usr/local中复制进文件，总是显示没有权限？


 发布于2016-08-27 11:36对usr文件夹进行操作需要有超级管理员的权限才行，你可以切换为超级管理员进行操作，或者在命令前面加 sudo；

如 sudo cp 1.txt usr/local

添加sudo用户：


配置sudo必须通过编辑/etc/sudoers文件，而且只有超级用户才可以修改它，还必须使用visudo编辑。之所以使用visudo有两个原因，一是它能够防止两个用户同时修改它；二是它也能进行有限的语法检查。所以，即使只有你一个超级用户，你也最好用visudo来检查一下语法。

解决办法如下

1.打开sudoers文件

切换到root用户下，cd root,运行visudo命令,visudo命令是用来编辑修改/etc/sudoers配置文件

[root@master ~]# visudo

2.修改suduers文件

找到如下图所示，标出红线的一行

root  ALL=(ALL)    ALL

给liudiwei添加sudo权限 
在“root ALL=(ALL) ALL”这一行下面，再加入一行：

liudiwei ALL=(ALL)     ALL

3.测试是否成功

切换到普通用户

su liudiwei
cd ~
sudo mkdir test

恭喜，验证密码后，通过！

好了，我们限制一下foobar的权利，不让他为所欲为。比如我们只想让他像root那样使用ls和ifconfig，把那一行改为： foobar localhost= /sbin/ifconfig, /bin/ls

现在让我们来看一下那三个ALL到底是什么意思。第一个ALL是指网络中的主机，我们后面把它改成了主机名，它指明foobar可以在此主机上执行后面的命令。第二个括号里的ALL是指目标用户，也就是以谁的身份去执行命令。最后一个ALL当然就是指命令名了。例如，我们想让foobar用户在linux主机上以jimmy或rene的身份执行kill命令，这样编写配置文件： foobar linux=(jimmy,rene) /bin/kill 但这还有个问题，foobar到底以jimmy还是rene的身份执行？这时我们应该想到了sudo -u了，它正是用在这种时候。 foobar可以使用sudo -u jimmy kill PID或者sudo -u rene kill PID，但这样挺麻烦，其实我们可以不必每次加-u，把rene或jimmy设为默认的目标用户即可。再在上面加一行： Defaults:foobar runas_default=rene Defaults后面如果有冒号，是对后面用户的默认，如果没有，则是对所有用户的默认。就像配置文件中自带的一行： Defaults env_reset 另一个问题是，很多时候，我们本来就登录了，每次使用sudo还要输入密码就显得烦琐了。我们可不可以不再输入密码呢？当然可以，我们这样修改配置文件： foobar localhost=NOPASSWD: /bin/cat, /bin/ls 再来sudo一下： [foobar@localhost ~]$ sudo ls /rootanaconda-ks.cfg Desktop install.log install.log.syslog 当然，你也可以说“某些命令用户foobar不可以运行”，通过使用!操作符，但这不是一个好主意。因为，用!操作符来从ALL中“剔出”一些命令一般是没什么效果的，一个用户完全可以把那个命令拷贝到别的地方，换一个名字后再来运行。

再次运行,以sudo前缀解压：

sudo tar -zvxf redis /usr/local


解压仍失败，忘了解压的-C参数：

Not found in archive

查了一下，原来是要在命令中加上-C这个参数.

又查了一下，C这个参数是“创建新的档案文件”。


再次解压成功

切换到/usr/local/redis目录，发现可以进入，查看该目录权限发现：

drwxrwxr-x. 6 root root  4096 Jul 14 19:28 redis-4.0.0


原来xiaobai添加到sudo,sudo安装，该目录other成员也有r-x权限，说明可以进入


在解压好的redis目录执行make && make install，安装失败，切换到root仍然提示：

[root@RedHat-BG redis-4.0.0]# pwd
/usr/local/redis-4.0.0
[root@RedHat-BG redis-4.0.0]# make
cd src && make all
make[1]: Entering directory `/usr/local/redis-4.0.0/src'


Hint: It's a good idea to run 'make test' ;)


make[1]: Leaving directory `/usr/local/redis-4.0.0/src'
[root@RedHat-BG redis-4.0.0]# make install
cd src && make install
make[1]: Entering directory `/usr/local/redis-4.0.0/src'


Hint: It's a good idea to run 'make test' ;)


    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
make[1]: Leaving directory `/usr/local/redis-4.0.0/src'

解决：

解压缩

tar -zxvf redis-3.0.7.tar.gz

cd redis-3.0.7

这全很正常没有什么可以说的，主要是下面，进入到redis-3.0.7目录之后，要是执行

make

make install 会把redis默认安装到/usr/local/bin/redis下

但是我只是一个普通的redis用户，我不想给他sudo权限也不想用root去执行怎么办呢

方法是：

bash-4.1$ PREFIX=/opt/redis make
bash-4.1$ PREFIX=/opt/redis make install

指定到你想要安装的目录下就可以了，大功告成


[root@RedHat-BG redis-4.0.0]# make PREFIX=/usr/local/redis install
cd src && make install
make[1]: Entering directory `/usr/local/redis-4.0.0/src'


Hint: It's a good idea to run 'make test' ;)

集群架设：


从现在开始全部用root操作，普通用户各种权限不足：

创建 Redis 节点

首先在 192.168.31.245 机器上 /root/software/redis-3.2.4 目录下创建 redis_cluster 目录；

mkdir redis_cluster　　

在 redis_cluster 目录下，创建名为7000、7001、7002的目录，并将 redis.conf 拷贝到这三个目录中

mkdir 7000 7001 7002<br>cp redis.conf redis_cluster/7000
cp redis.conf redis_cluster/7001
cp redis.conf redis_cluster/7002

分别修改这三个配置文件，修改如下内容

RedHat6.5虚拟机架设Redis和Kafka伪集群
port  7000                                        //端口7000,7002,7003        
bind 本机ip                                       //默认ip为127.0.0.1 需要改为其他节点机器可访问的ip 否则创建集群时无法访问对应的端口，无法创建集群
daemonize    yes                               //redis后台运行
pidfile  /var/run/redis_7000.pid          //pidfile文件对应7000,7001,7002
cluster-enabled  yes                           //开启集群  把注释#去掉
cluster-config-file  nodes_7000.conf   //集群的配置  配置文件首次启动自动生成 7000,7001,7002
cluster-node-timeout  15000                //请求超时  默认15秒，可自行设置
appendonly  yes                           //aof日志开启  有需要就开启，它会每次写操作都记录一条日志

bind 192.168.43.105

protected-mode no

port 7001

daemonize yes

pidfile /var/run/redis_7001.pid

appendonly yes

cluster-enabled yes

cluster-config-file nodes-7001.conf

cluster-node-timeout 15000

需要注意的两点：

1.cp -R是递归复制目录内容,复制其他节点改好的内容快一些，只要改端口相关即可，顺便在改的过程中查看这个被复制节点的配置是否正确，因为当前就是它配置的拷贝


2.启动时指定不同配置文件，命令都是bin目录下的redis-server,注意./方式执行可执行文件，&符号的添加是为了可以退出到命令行而redis不会被结束


这样创建了6个cluster模式的节点，太少不行，redis集群有一个最小节点数限制。


执行redis的创建集群命令创建集群

cd /usr/local/redis3.0/src

./redis-trib.rb  create --replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005

6.1执行上面的命令的时候会报错，因为是执行的ruby的脚本，需要ruby的环境

错误内容：/usr/bin/env: ruby: No such file or directory

所以需要安装ruby的环境，这里推荐使用yum install ruby安装

yum install ruby

 

6.2然后再执行第6步的创建集群命令，还会报错，提示缺少rubygems组件，使用yum安装

 

错误内容：

./redis-trib.rb:24:in `require': no such file to load -- rubygems (LoadError)

from ./redis-trib.rb:24

yum install rubygems

6.3再次执行第6步的命令，还会报错，提示不能加载redis，是因为缺少redis和ruby的接口，使用gem 安装

错误内容：

/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- redis (LoadError)

from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'

from ./redis-trib.rb:25

 

gem install  redis --version 3.0.0

注意：gem install redis --version 3.0.0 失败的话，需要修改一下gem的源
gem sources --remove https://rubygems.org/
gem sources -a https://ruby.taobao.org/


无法执行yum安装：


redhat6.5 配置使用centos的yum源2014-09-11 16:11:39 标签：yum redhat6 centos源

新安装了redhat6.5.安装后，登录系统，使用yum update 更新系统。提示：

This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

无法更新。

redhat 默认自带的 yum 源需要注册，才能更新。我们想不花钱也可以更新，需要替换掉redhat的yum源。

1.检查是否安装yum包

查看RHEL是否安装了yum，若是安装了，那么又有哪些yum包：

[root@localhost ~]# rpm -qa |grep yum

yum-metadata-parser-1.0-8.fc6

yum-3.0.1-5.el5

yum-rhn-plugin-0.4.3-1.el5

yum-updatesd-3.0.1-5.el5

2 删除redhat自带的yum包

卸载上面显示的所有yum包：

[root@localhost ~]# rpm -qa|grep yum|xargs rpm -e --nodeps（不检查依赖，直接删除rpm包）

再用

[root@localhost ~]# rpm -qa |grep yum

[root@localhost ~]# 

查看，无信息显示表示已经卸载完成。

3.下载新的yum包。使用Centos6.5的yum包

123 # wget http://mirrors.163.com/centos/6/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm# wget http://mirrors.163.com/centos/6/os/i386/Packages/yum-3.2.29-40.el6.centos.noarch.rpm# wget http://mirrors.163.com/centos/6/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm


安装yum软件包

注意:单个的安装包可能会依赖其它包（例如yum和yum-fastestmirror会相互依赖），所以我们可以把所有这些包放在一起，用一行命令将它们同时安装即可：

1 # rpm -ivh yum-metadata-parser-1.1.2-16.el6.i686.rpm yum-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

4.更换yum源。使用163的源

123 # cd /etc/yum.repos.d/# wget  http://mirrors.163.com/.help/CentOS6-Base-163.repo# vi CentOS6-Base-163.repo

编辑文件，把文件里面的$releasever全部替换为版本号，即6.5 最后保存！或者直接把下面的内存拷贝到CentOS6-Base-163.repo文件中即可（已经修改好）

5.清除原有缓存

1 # yum clean all

重建缓存，以提高搜索安装软件的速度

1 # yum makecache

6.更新系统

1 # yum update

缺少刚才没安装成功的rpm-python


源帖子：

centos 卸载python和yum之后的解决办法

网上看到有同学yum不能使用的消息，出现了下面的结果

RedHat6.5虚拟机架设Redis和Kafka伪集群

 

无赖的使用了网上的很多方法，还是不行。

于是我卸载了python和yum，觉得自己重新安装python和yum。

步骤1：卸载python

rpm -qa|grep python|xargs rpm -e --allmatches --nodeps

whereis python|xargs rm -fr

步骤2：卸载yum

rpm -qa|grep yum|xargs rpm -e --allmatches --nodeps

rm -rf /etc/yum.repos.d/*

whereis yum|xargs rm -fr

步骤3：安装python

在任何一个镜像站中找到你系统对应版本的python rpm包（我的是centos 6.9的64位系统，使用的镜像是http://mirrors.163.com/centos/6.9/os/x86_64/Packages/）

按 Ctrl+C 复制代码wget http://mirrors.163.com/centos/6.9/os/x86_64/Packages/python-2.6.6-66.el6_8.x86_64.rpm


wget http://mirrors.163.com/centos/6.9/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm


wget http://mirrors.163.com/centos/6.9/os/x86_64/Packages/python-pycurl-7.19.0-9.el6.x86_64.rpm


wget http://mirrors.163.com/centos/6.9/os/x86_64/Packages/python-devel-2.6.6-66.el6_8.x86_64.rpm


wget http://mirrors.163.com/centos/6.9/os/x86_64/Packages/python-libs-2.6.6-66.el6_8.x86_64.rpm


wget http://mirrors.163.com/centos/6.9/os/x86_64/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm


wget http://mirrors.163.com/centos/6.9/os/x86_64/Packages/rpm-python-4.8.0-55.el6.x86_64.rpm按 Ctrl+C 复制代码

 

切换到/usr/local/src/python路径下

rpm -ivh python-*   rpm-python-*

如果中间过程出现了类似下面的代码，这是包与包之间的依赖关系，只需要卸载已经安装的包（rpm -e 包名（没有.rpm后缀）），然后先安装依赖包

如：

      rpm -e yum-metadata-parser-1.1.2-16.el6.x86_64       rpm -ivh /yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

RedHat6.5虚拟机架设Redis和Kafka伪集群

步骤4：安装yum

按 Ctrl+C 复制代码wget http://mirrors.163.com/centos/6.9/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm  


wget http://mirrors.163.com/centos/6.9/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm  


wget http://mirrors.163.com/centos/6.9/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-40.el6.noarch.rpm按 Ctrl+C 复制代码

切换到/usr/local/src/python路径下

rpm -ivh yum-*

步骤5：测试

运行

yum

（成功）

 RedHat6.5虚拟机架设Redis和Kafka伪集群

继续安装，仍然依赖缺少或冲突，重装了一个rpm仍然冲突，无奈最后绝招：加--nodeps 或--force强行安装，成功：

这是错误提示，大侠帮忙看看如何解决。谢谢！收起 加上 --nodeps,意思不考虑依赖2.更狠的--force，强制安装你可以在这两个之前试试--aid自己解决依赖

然而最终rpm方式安装仍然不起作用：新安装的yum还是无法联网获取任何东西进行安装，无奈直接安装Redis集群所缺少的ruby相关，rpm方式仍然提示依赖缺少或冲突问题，

上网找到源码编译安装rubygem的方式:


redhat下安装ruby2.2以及安装rubygems

刚开始尝试通过yum安装ruby,结果安装以后发现安装的ruby版本是1.9.7，通过通过gem install rest-lient的时候说ruby版本过低，于是只好从头再来通过源代码编译的方式安装ruby。

一.安装ruby

1.实现去ruby官网下载最新的稳定版本：

https://www.ruby-lang.org/en/downloads/

    2.通过filezila将tar包上传到linux上面

RedHat6.5虚拟机架设Redis和Kafka伪集群

3.执行以下命令

tar xzvf ruby-2.2.0.tar.gzcd ruby-2.2.0./configure –prefix=/usr/local/rubymake && make instal-prefix是将ruby安装到指定目录，安装的时候开始没有使用root用户安装，出现问题，于是切换到root用户执行 make && make install，完成。4.添加环境变量编辑/etc/profile文件：vim /etc/profile添加在最后添加export RUBY_HOME=/usr/local/ruby2.2.0export PAHT:RUBY_HOME/bin保存。source /etc/profileruby --version二.安装rubygems1.下载rubygems: http://www.oschina.net/news/19237/rubygems-v-1852.tar xzvf rubygems-1.8.5.tgzcd rubygems-1.8.5/ruby setup.rbgem --version
     **安装三个包

gem install  spreadsheet

gem install  pry

gem install rest-client

再次执行集群搭建，提示缺少ruby,卸载当前所有ruby相关，触类旁通吧：

rpm -qa|grep ruby|xargs rpm -e --allmatches --nodeps

whereis ruby|xargs rm -fr

注意有时复制命令出错是因为复制的"--"出现问题,手动修改为两个杠线

--

完全卸载后重装：

执行以下命令

tar xzvf ruby-2.2.0.tar.gz cd ruby-2.2.0 ./configure –prefix=/usr/local/ruby make && make instal -prefix是将ruby安装到指定目录，安装的时候开始没有使用root用户安装，出现问题，于是切换到root用户执行 make && make install，完成。

安装ruby 1.9.3p551版本，并先创建上面的文件夹，亲爱的。

设置PATH路径,把自己安装的ruby放在系统PATH前面，避免调用操作系统自带的ruby  
export PATH=/usr/local/ruby/bin:$PATH


查看：

[root@RedHat-BG ruby]# vim /etc/profile
[root@RedHat-BG ruby]# source /etc/profile
[root@RedHat-BG ruby]# ruby -v
ruby 1.9.3p551 (2014-11-13 revision 48407) [x86_64-linux]


集群命令仍然不成功，提示安装rubygems：

tar xzvf rubygems-1.8.5.tgz cd rubygems-1.8.5/ ruby setup.rb gem --version
     **安装三个包

gem install  spreadsheet

gem install  pry

gem install rest-client

ruby官方下载安装最新ruby .

Ruby1.9.1 以后的版本自带RubyGems，直接在CMD窗口下输入指令 gem update --system 升级到最新版即可

升级出现以下情况：

While executing gem ... (Gem::RemoteFetcher::FetchError)


Rubygems官方网站被Wall了，导致在线安装软件gem包的时候无法顺利进行，往往需要借助VPN才能成功安装，所以带来了很大的不便。

解决方法：更换为国内源.

1. http://ruby.taobao.org/

2. https://gems.ruby-china.org

gem source   查看源列表

更换源命令：gem source -a http://ruby.taobao.org

删除源命令：gem source -r https://rubygems.org/ 

更新源命令：gem source -u 

若报错Error fetching url地址 SSL_connect 则将https该为http

 更新了gem:

执行redis-trib.rb时遇到的问题

执行redis-trib.rb时遇到的问题

redis-trib.rb是Redis Cluster的一个常用工具。下面记录了执行此命令时遇到的一系列错误。

redis-trib.rb create --replicas 1  127.0.0.1:7379 127.0.0.1:7380 127.0.0.1:7381 127.0.0.1:7382 127.0.0.1:7383 127.0.0.1:7384 /usr/bin/env: ruby: 没有那个文件或目录

看来是ruby没有安装，于是执行：

yum install -y ruby//安装ruby redis-trib.rb create --replicas 1  127.0.0.1:7379 127.0.0.1:7380 127.0.0.1:7381 127.0.0.1:7382 127.0.0.1:7383 127.0.0.1:7384 redis-trib.rb:24:in `require': no such file to load -- rubygems (LoadError)         from src/redis-trib.rb:24

ruby安装成功，但是rubygem没有安装，所以导致了上述错误，于是继续：

yum install -y rubygems//安装rubygem redis-trib.rb create --replicas 1  127.0.0.1:7379 127.0.0.1:7380 127.0.0.1:7381 127.0.0.1:7382 127.0.0.1:7383 127.0.0.1:7384 /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- redis (LoadError)         from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'         from src/redis-trib.rb:25

rubygem安装成功，但是新的错误又出现了。google了一下，发现是ruby版本太低了。yum安装的版本是1.8.7，但是redis需要的是1.9.3或者更高，于是升级ruby版本到1.9.3.

curl -L get.rvm.io | bash -s stable source /etc/profile.d/rvm.sh//安装rvm rvm install 1.9.3//安装ruby1.9.3 rvm use 1.9.3 --default//设置ruby1.9.3为默认的ruby，因为还安装有1.8.3 gem install redis ERROR:  Could not find a valid gem 'redis' (>= 0), here is why:           Unable to download data from https://rubygems.org/ - Errno::ETIMEDOUT: Connection timed out - connect(2) (https://api.rubygems.org/latest_specs.4.8.gz) ERROR:  Possible alternatives: redis

又遇到新的错误了，看来是连接gem源出错了，于是增加新的gem源：

gem sources -a http://ruby.taobao.org///添加淘宝的gem源

然后”gem install redis“执行成功，之后的”redis-trib.rb create ......“也ok了。

BTW：其实ruby1.8.7也支持redis-trib.rb，也就是说在ruby1.8.7上执行”redis-trib.rb create ......“时出现的错误是由于没有安装针对redis的gem包，所以只要成功执行”gem install redis"即可。不过不建议使用ruby1.8.7，因为这个版本有点老了，使用rvm安装ruby1.8.7时，提示对此版本已经不提供支持了。

 那么大哥我的redis-4.0.0有点太高了。ruby好不容易安装上1.9.3我是不会卸载重装了，决定降低redis版本到3.0


删除redis:

删除/usr/local/lib　目录下与redis 相关的命令

也就是你安装在/usr/local/redis/bin中生成的那些redis相关可执行文件

重装3.0.0：


PREFIX=/usr/local/redis make

PREFIX=/usr/local/redis make install


然后/usr/local/redis/bin中又会生成那些redis命令

尝试启动redis-server成功


原来配置集群的那些配置文件不变，尝试每个启动

启动失败：

[root@RedHat-BG bin]# ./redis-server ../redis-cluster/7002/redis.conf


*** FATAL CONFIG FILE ERROR ***
Reading the configuration file, at line 88
>>> 'protected-mode no'
Bad directive or wrong number of arguments


比较了3.0.0版本的配置文件，发现没有这个protected-mode配置，其他基本一样，于是把每个配置文件中该配置去掉


然而最终太多不同，还是挨个拷贝的3.0.0版本配置文件改的，启动，然后gem install redis时仍然提示需要ruby 2.2.2以上版本，于是

一整天白折腾了


删除ruby。。。。

重装2.2.2，按照配置安装位置，make,make install,配置ruby的path路径依次操作，非常顺利，可能此前缺失的一些lib在重启虚拟机后生效了
