1、安装配置redis的cluster集群
1.1环境准备
六台服务器
① 192.168.37.17：6379
② 192.168.37.27：6379
③ 192.168.37.37：6379
④ 192.168.37.47：6379
⑤ 192.168.37.57：6379
⑥ 192.168.37.67：6379
1.2 编译安装redis（六台服务器相同）
安装相关依赖库：yum -y install gcc automake autoconf libtool make zlib zlib-devel tcl
切换目录：cd /usr/local/src/
解包：tar xvf redis-4.0.14.tar.gz
切换目录：cd redis-4.0.14
安装：make PREFIX=/usr/local/redis install
复制配置文件：mkdir /usr/local/redis/etc cp /usr/local/src/redis-4.0.14/redis.conf /usr/local/redis/etc/
创建软连接：ln -sv /usr/local/redis/bin/redis-* /usr/bin/
创建用户：groupadd -g 1500 redis && useradd -u 1500 -g 1500 redis -s /sbin/nologin
创建相关目录：mkdir -pv /usr/local/redis/{etc,logs,data,run}
更改权限：chown redis.redis -R /usr/local/redis/
1.3 安装 集群管理工具 redis-trib.rb
yum安装：yum install ruby rubygems -y
cp /usr/local/src/redis-4.0.14/src/redis-trib.rb /usr/bin/
版本较低无法使用：
删除：rm -f /usr/bin/redis-trib.rb
1.4 解决 ruby 版本较低问题：
卸载ruby：yum remove ruby rubygems -y
删除文件：rm -f /usr/bin/redis-trib.rb
下载2.5版本ruby：wget https://cache.ruby-lang.org/pub/ruby/2.5/ruby-2.5.5.tar.gz
解包：tar xf ruby-2.5.5.tar.gz
切换目录：cd ruby-2.5.5
安装： ./configuremake && make install
创建软连接： cp /opt/redis-4.0.14/src/redis-trib.rb /usr/local/redis/bin/
1.5 修改配置文件

依次拷贝到其他服务器：scp /usr/local/redis/etc/redis.conf 192.168.37.67:/usr/local/redis/etc/redis.conf
启动：redis-server /usr/local/redis/etc/redis.conf
1.6 创建 redis cluster 集群
创建：redis-trib.rb create --replicas 1 192.168.37.17:6379 192.168.37.27:6379 192.168.37.37:6379 192.168.37.47:6379 192.168.37.57:6379 192.168.37.67:6379
1.3 查看集群状态
1.3.1 验证master状态
1.3.2 验证集群状态
1.3.3 查看集群node对应关系
1.3.4 验证集群写入key
2、安装配置memcached高可用
2.1 环境准备
server1：192.168.37.57
server2：192.168.37.67
2.2 部署 repcached
安装相关依赖库：yum -y install libevent libevent-devel gcc automake autoconf libtool make zlib zlib-devel
下载包：wget https://sourceforge.net/projects/repcached/files/repcached/2.2.1-1.2.8/memcached-1.2.8-repcached-2.2.1.tar.gz
解包：tar xvf memcached-1.2.8-repcached-2.2.1.tar.gz
切换目录：cd memcached-1.2.8-repcached-2.2.1
安装：./configure --prefix=/usr/local/repcached --enable-replication
make #报错如下
解决报错：
vim memcached.c
56 #ifndef IOV_MAX
57 #if defined(__FreeBSD__) || defined(__APPLE__)
58 # define IOV_MAX 1024
59 #endif
60 #endif
改为如下内容：
55 /* FreeBSD 4.x doesn't have IOV_MAX exposed. */
56 #ifndef IOV_MAX
57 # define IOV_MAX 1024
58 #endif
继续安装：make && make install
2.3 验证是否可执行
memcached -h
2.4 启动 memcache
2.4.1 server 1 相关操作
/usr/local/repcached/bin/memcached -d -m 2048 -p 11211 -u root -c 2048 -x 192.168.37.67 -X 16000
2.4.2server 2 相关操作
/usr/local/repcached/bin/memcached-d -m 2048 -p 11211 -u root -c 2048 -x192.168.37.57 -X 16000
2.5 连接到 memcache 验证数据
3、安装VMware exsi
3.1 安装准备
调整内存及虚拟化功能
