redis 4.*

部署步骤

1. 下载源码：wget http://download.redis.io/releases/redis-4.0.14.tar.gz

2. 编译安装：

   yum -y install gcc 
   tar -xaf redis-4.0.14.tar.gz
   cd redis-4.0.14
   make MALLOC=libc
   cp  src/redis-server src/redis-cli src/redis-trib.rb ${redispath} (redispath为目标安装位置)
   # cd src;cp redis-server redis-sentinel  redis-benchmark redis-check-rdb redis-check-aof /usr/local/bin/
   copy 配置文件redis.conf到安装位置，根据需要修改配置文件

   集群版：redis.conf（单节点修改cluster-enabled no）

   protected-mode yes
   port 6379
   tcp-backlog 511
   timeout 0
   tcp-keepalive 300
   daemonize yes
   supervised no
   pidfile "redis.pid"
   loglevel notice
   logfile "redis.log"
   databases 16
   always-show-logo yes   
   stop-writes-on-bgsave-error yes
   rdbcompression yes
   rdbchecksum yes
   dbfilename "dump.rdb"
   dir "."
   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 no
   auto-aof-rewrite-percentage 100
   auto-aof-rewrite-min-size 512mb
   aof-load-truncated yes
   aof-use-rdb-preamble no
   lua-time-limit 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
   cluster-enabled yes
   #绑定的ip地址
   bind 0.0.0.0
   #实例最大内存
   maxmemory 6gb

   调整内核参数：

   1. 关闭THP

      echo never > /sys/kernel/mm/transparent_hugepage/enabled
      echo "echo never > /sys/kernel/mm/transparent_hugepage/enabled" >>/etc/rc.local

   2. 修改sysctl.conf

      vi /etc/sysctl.conf
      -------------------------------
      vm.overcommit_memory = 1
      net.core.somaxconn = 2048

   3. 使内核参数生效

      sysctl -p

   新建系统服务：新建下面文件，复制下面内容

   vi /lib/systemd/system/redis.service
   ---------------------------------------
   [Unit]
   Description=redis
   After=network.target
   ​
   [Service]
   Type=forking
   WorkingDirectory=/home/admin/redis
   PIDFile=/home/admin/redis/redis.pid
   ExecStart=/home/admin/redis/redis-server  /home/admin/redis/redis.conf
   ExecReload=/bin/kill -s HUP $MAINPID
   ExecStop=/bin/kill -s QUIT $MAINPID
   PrivateTmp=true
   LimitNOFILE=64000
   ​
   [Install]
   WantedBy=multi-user.target

   systemctl daemon-reload
   systemctl enable redis
   systemctl restart redis

   集群版复制二进制文件到相应节点、添加对系统服务器并启动初始化集群步骤：

   1. 安装rvm（ruby管理器）

      gpg2 --keyserver hkp://pool.sks-keyservers.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
      curl -sSL https://get.rvm.io | bash -s stable
      source /etc/profile.d/rvm.sh
      rvm install ruby-2.6.3

   2. yum -y install gem

   3. gem install redis

   4. 初始化集群：

      ./redis-trib.rb create --replicas 1 10.8.140.43:6379 10.8.140.44:6379 10.8.140.45:6379 10.8.140.44:6380 10.8.140.45:6380 10.8.140.43:6380

redis 5.*

安装步骤和4.*一致初始化集群时直接使用redis-cli初始化，不需要使用rubyredis-cli --cluster create 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 --cluster-replicas 1
