Redis集群安装node
1集群机器分布linux
192.168.1.133 redis1c++
192.168.1.134 redis2git
192.168.1.135 redis3github
2 免密登陆redis
ssh-keygensql
ssh-copy-id 192.168.1.133ruby
ssh-copy-id 192.168.1.134bash
ssh-copy-id 192.168.1.135app
3 关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
setenforce 0
sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/g’ /etc/selinux/config
4设置yum源
这里添加阿里源
cd /etc/yum.repos.d/
wget https://mirrors.aliyun.com/repo/Centos-7.repo
wget https://mirrors.aliyun.com/repo/epel-7.repo
5修改系统参数
vi /etc/security/limits.conf
* soft nofile 65535
* hard nofile 655350
* soft nproc 65535
* hard nproc 655350
安装依赖
yum install gcc make tcl –y
yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel make bzip2 autoconf automake libtool bison sqlite-devel iconv-devel
6 安装redis
mkdir -p /opt/haizhi/redis
cd /opt/haizhi/redis/
wget http://download.redis.io/releases/redis-4.0.6.tar.gz
tar zxvf redis-4.0.6.tar.gz
cd redis-4.0.6/ #编译安装完成后会生成bin目录
make & make PREFIX=/opt/haizhi/redis install
cp -a /opt/haizhi/redis/redis-4.0.6/src/redis-trib.rb /opt/haizhi/redis/bin/
#上面是复制集群命令 到bin目录
注意：若是make出错 使用make MALLOC=libc
7 建立集群须要的目录和配置
建立3个实例目录
cd /opt/haizhi/redis/
mkdir -p cluster-6379/{conf,data,log,pid}
mkdir -p cluster-6380/{conf,data,log,pid}
mkdir -p cluster-6381/{conf,data,log,pid}
为每一个实例建立配置文件（以6379为例）
[root@localhost redis]# cat cluster-6379/conf/redis_6379.conf
bind 0.0.0.0
protected-mode yes
port 6379
tcp-backlog 511
timeout 0
tcp-keepalive 300
daemonize yes
supervised no
pidfile /opt/haizhi/redis/cluster-6379/conf/redis_6379.pid
loglevel notice
logfile "/opt/haizhi/redis/cluster-6379/log/redis_6379.log"
databases 16
always-show-logo yes
save 900 1
save 300 10
save 60 10000
stop-writes-on-bgsave-error yes
rdbcompression yes
rdbchecksum yes
dbfilename dump.rdb
dir /opt/haizhi/redis/cluster-6379/data
slave-serve-stale-data yes
slave-read-only yes
repl-diskless-sync no
repl-diskless-sync-delay 5
repl-disable-tcp-nodelay no
slave-priority 100
lazyfree-lazy-eviction no
lazyfree-lazy-expire no
lazyfree-lazy-server-del no
slave-lazy-flush no
appendonly yes
appendfilename "appendonly.aof"
appendfsync everysec
no-appendfsync-on-rewrite yes
auto-aof-rewrite-percentage 100
auto-aof-rewrite-min-size 64mb
aof-load-truncated yes
aof-use-rdb-preamble no
lua-time-limit 5000
cluster-enabled yes
cluster-config-file /opt/haizhi/redis/cluster-6379/conf/nodes-6379.conf
cluster-node-timeout 5000
slowlog-log-slower-than 10000
slowlog-max-len 128
latency-monitor-threshold 0
notify-keyspace-events ""
hash-max-ziplist-entries 512
hash-max-ziplist-value 64
list-max-ziplist-size -2
list-compress-depth 0
set-max-intset-entries 512
zset-max-ziplist-entries 128
zset-max-ziplist-value 64
hll-sparse-max-bytes 3000
activerehashing yes
client-output-buffer-limit normal 0 0 0
client-output-buffer-limit slave 256mb 64mb 60
client-output-buffer-limit pubsub 32mb 8mb 60
hz 10
aof-rewrite-incremental-fsync yes
其余实例只需修改6379为6380 6381 便可使用
8 启动各实例
./redis-server /opt/haizhi/redis/cluster-6379/conf/redis_6379.conf
./redis-server /opt/haizhi/redis/cluster-6380/conf/redis_6380.conf
./redis-server /opt/haizhi/redis/cluster-6381/conf/redis_6381.conf
[root@localhost redis]# netstat -lnupt
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:6379 0.0.0.0:* LISTEN 17736/./redis-serve
tcp 0 0 0.0.0.0:6380 0.0.0.0:* LISTEN 17741/./redis-serve
tcp 0 0 0.0.0.0:6381 0.0.0.0:* LISTEN 17746/./redis-serve
以上步骤 三个节点都要执行安装操做
安装启动后再选一台机器设置集群
9 设置集群（选一台机器安装）
————————————不联网安装——————————————
9.1上传以下安装包
wget https://rubygems.org/rubygems/rubygems-2.7.8.tgz
wget https://cache.ruby-lang.org/pub/ruby/2.5/ruby-2.5.0.tar.gz
wget https://rubygems.global.ssl.fastly.net/gems/redis-3.2.2.gem
[root@test install_redis]# ll
-rw-r--r-- 1 root root 75776 2月 2 2016 redis-3.2.2.gem
-rw-r--r-- 1 root root 1723533 4月 25 2018 redis-4.0.6.tar.gz
-rw-r--r-- 1 root root 15834941 1月 25 2018 ruby-2.5.0.tar.gz
-rw-r--r-- 1 root root 920781 11月 19 11:24 rubygems-2.7.8.tgz
9.2 安装ruby环境
[root@test ]＃ mkdir /usr/local/ruby
[root@test ]＃ cd /usr/local/ruby
[root@test ruby]＃ cp /home/install_redis/ruby-2.5.0.tar.gz .
[root@test ruby]＃ tar -zxf ruby-2.5.0.tar.gz
[root@test ruby]＃ cd ruby-2.5.0/
[root@test ruby-2.5.0]＃ ./configure
[root@test ruby-2.5.0]＃ make && make install
[root@test ruby]# ruby -v
ruby 2.5.0p0 (2017-12-25 revision 61468) [x86_64-linux]
9.3 安装rubygems
[root@test ]＃ mkdir /usr/local/rubygems
[root@test ]＃ cd /usr/local/rubygems
[root@test rubygems]＃cp /home/install_redis/rubygems-2.7.8.tgz .
[root@test rubygems]＃tar zxf rubygems-2.7.8.tgz
[root@test rubygems]＃cd rubygems-2.7.8/
[root@test rubygems-2.7.8]＃ruby setup.rb
9.4 安装ruby-redis插件
[root@test ]＃ cd /home/install_redis/
[root@test ]＃ gem install redis-3.2.2.gem
上面完成后就能够执行第10步建立集群了
————————－联网安装—－———————————————－
redis官方提供了redis-trib.rb工具，可是在使用以前须要安装ruby，以及redis和ruby链接
参考https://blog.csdn.net/woxingwosu0100/article/details/77840528
9.1安装工具依赖环境（前面安装过）
yum install -y gcc-c++ gcc* patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bison sqlite-devel iconv-devel
9.2 安装rvm（ruby管理工具）
执行下面语句
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
或者
gpg2 --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
而后
执行 curl -L get.rvm.io | bash -s stable
#若是上面的链接失败，能够尝试:
curl -Lhttps://raw.githubusercontent.com/wayneeseguin/rvm/master/binscripts/rvm-installer| bash -s stable
执行 source /usr/local/rvm/scripts/rvm
rvm install 2.3.3
[root@server bin]# ruby --version
ruby 2.3.3p222 (2016-11-21 revision 56859) [x86_64-linux]
最后执行 gem install redis 安装
