linux上部署多实列redis（分装）

一、下载安装安装包
     wget http://www.redis.cn/download.html/redis-5.0.3.tar.gz
    （下载完查看大小1.86M，如果只有几十K，请直接上网页手动下载）
 
 
二、安装redis，修改允许后台运行
 
     #!/bin/bash
     
     yum install gcc-c++  -y
     
     tar -zxf redis-5.0.3.tar.gz
     cd redis-5.0.3
     make MALLOC=libc
     make
     cd src
     make install PREFIX=/usr/local/redis
     cd ..
     cp redis.conf /usr/local/redis/bin/
     cd ..
     rm -rf redis-5.0.3/
     cd /usr/local/redis/bin
     
     ##让redis可以后台启动
     AA=`cat -n redis.conf  | grep daemonize | grep -v "#" | awk '{print $1}'`
     sed -i ''"$AA"'c  daemonize yes'   redis.conf

三、单机多实例

  1：创建多实列目录和启动脚本：
     [root@localhost /]# mkdir /usr/local/redis/{conf,pid,log,data,}
     [root@localhost /]# mkdir /usr/local/redis/data/{6380,6381,6382}
     [root@localhost /]# cd /usr/local/redis/bin/
     [root@localhost /]# cp redis-server redis-server6380;cp redis-server redis-server6381;cp redis-server redis-server6382
     [root@localhost /]# mv redis.conf  /usr/local/redis/conf/
     [root@localhost /]# cd /usr/local/redis/conf/
     [root@localhost /]# cp redis.conf  redis6380.conf
     [root@localhost /]# cp redis.conf  redis6381.conf
     [root@localhost /]# cp redis.conf  redis6382.conf
  
  
  
  2：分别修改配置文件：（这里只显示一个配置文件，其他配置文件以此类推的修改）
     vim /usr/local/redis/conf/redis6380.conf

92  port 6380    <== 端口
#pidfile " "(更改为:)  
158 pidfile /usr/local/redis/pid/redis_6380.pid   <== 进程id存放文件
171 logfile /usr/local/redis/log/redis_6380.log   <== 日志目录
#dir ./(更改为):
263 dir /usr/local/redis/data/6380/  <== db目录

四、启动和关闭脚本
 
     cat  /usr/bin/redis6380

#!/bin/bash
     
     cd  /usr/local/redis/bin
     
     case $1 in 
     start)
         ./redis-server6380 /usr/local/redis/conf/redis6380.conf;ps -ef | grep redis | grep 6380 > /dev/null && echo "redis6380 Successful opening" || echo "redis6380 Open failure"
         ;;
     stop)
         killall ./redis-server6380 2> /dev/null;sleep 1;ps -ef | grep -v grep | grep  redis-server6380  && echo "redis6380 Shutdown failure"  || echo "redis6380 Shut down successfully"
         ;;
  restart)
         killall ./redis-server6380 2> /dev/null;sleep 1;ps -ef | grep -v grep | grep  redis-server6380  && echo "redis6380 Shutdown failure"  || echo "redis6380 Shut down successfully"
         ./redis-server6380 /usr/local/redis/conf/redis6380.conf;ps -ef | grep redis | grep 6380 > /dev/null && echo "redis6380 Successful opening" || echo "redis6380 Open failure"
         ;;
        *)
         exit
         exit
         ;;
     esac

cat  /usr/bin/redis6381

#!/bin/bash
     
     cd  /usr/local/redis/bin
     
     case $1 in 
     start)
         ./redis-server6381 /usr/local/redis/conf/redis6381.conf;ps -ef | grep redis | grep 6381 > /dev/null && echo "redis6381 Successful opening" || echo "redis6381 Open failure"
         ;;
     stop)
         killall ./redis-server6381 2> /dev/null;sleep 1;ps -ef | grep -v grep | grep  redis-server6381  && echo "redis6381 Shutdown failure"  || echo "redis6381 Shut down successfully"
         ;;
  restart)
         killall ./redis-server6381 2> /dev/null;sleep 1;ps -ef | grep -v grep | grep  redis-server6381  && echo "redis6381 Shutdown failure"  || echo "redis6381 Shut down successfully"
         ./redis-server6381 /usr/local/redis/conf/redis6381.conf;ps -ef | grep redis | grep 6381 > /dev/null && echo "redis6381 Successful opening" || echo "redis6381 Open failure"
         ;;
        *)
         exit
         exit
         ;;
     esac

cat  /usr/bin/redis6382

#!/bin/bash
     
     cd  /usr/local/redis/bin
     
     case $1 in 
     start)
         ./redis-server6382 /usr/local/redis/conf/redis6382.conf;ps -ef | grep redis | grep 6382 > /dev/null && echo "redis6382 Successful opening" || echo "redis6382 Open failure"
         ;;
     stop)
         killall ./redis-server6382 2> /dev/null;sleep 1;ps -ef | grep -v grep | grep  redis-server6382  && echo "redis6382 Shutdown failure"  || echo "redis6382 Shut down successfully"
         ;;
  restart)
         killall ./redis-server6382 2> /dev/null;sleep 1;ps -ef | grep -v grep | grep  redis-server6382  && echo "redis6382 Shutdown failure"  || echo "redis6382 Shut down successfully"
         ./redis-server6382 /usr/local/redis/conf/redis6382.conf;ps -ef | grep redis | grep 6382 > /dev/null && echo "redis6382 Successful opening" || echo "redis6382 Open failure"
         ;;
        *)
         exit
         exit
         ;;
     esac

#加上可执行权限：
  chmod +x /usr/bin/redis*

五、启动和关闭脚本使用说明：

 1：启动：
    [root@beiyong bin]# redis6380 start
    redis6380 Successful opening
    [root@beiyong bin]# redis6381 start
    redis6381 Successful opening
    [root@beiyong bin]# redis6382 start
    redis6382 Successful opening
    [root@beiyong bin]# ps -ef | grep -v grep | grep redis
    root      29713      1  0 15:28 ?        00:00:00 ./redis-server6380 127.0.0.1:6380
    root      29723      1  0 15:28 ?        00:00:00 ./redis-server6381 127.0.0.1:6381
    root      29732      1  0 15:28 ?        00:00:00 ./redis-server6382 127.0.0.1:6382
 
 
 2：关闭：
    [root@beiyong bin]# redis6380 stop
    redis6380 Shut down successfully
    [root@beiyong bin]# ps -ef | grep -v grep | grep redis
    root      29723      1  0 15:28 ?        00:00:00 ./redis-server6381 127.0.0.1:6381
    root      29732      1  0 15:28 ?        00:00:00 ./redis-server6382 127.0.0.1:6382
 
 
 3：重启：
    [root@beiyong bin]# redis6380 restart
    redis6380 Shut down successfully
    redis6380 Successful opening
    [root@beiyong bin]# ps -ef | grep -v grep | grep redis
    root      29723      1  0 15:28 ?        00:00:00 ./redis-server6381 127.0.0.1:6381
    root      29732      1  0 15:28 ?        00:00:00 ./redis-server6382 127.0.0.1:6382
    root      29759      1  0 15:30 ?        00:00:00 ./redis-server6380 127.0.0.1:6380
    
    [root@beiyong bin]# redis6381 restart
    redis6381 Shut down successfully
    redis6381 Successful opening
    [root@beiyong bin]# ps -ef | grep -v grep | grep redis
    root      29732      1  0 15:28 ?        00:00:00 ./redis-server6382 127.0.0.1:6382
    root      29759      1  0 15:30 ?        00:00:00 ./redis-server6380 127.0.0.1:6380
    root      29776      1  0 15:30 ?        00:00:00 ./redis-server6381 127.0.0.1:6381

六、#开机自启：
     echo  "/usr/local/redis/bin/redis-server6380 /usr/local/redis/conf/redis6380.conf"  >> /etc/rc.local
	 ……
	 ……

注意事项，多实列下还需要保持不一致的修改处（按自己的需求修改，配置文件默认是注释掉的）：

     dbfilename dump.rdb　　#多实例情况下需要修改，例如dump.6380.rdb
	 appendfilename "appendonly.aof"　　#多实例情况下需要修改,例如 appendonly_6380.aof
	 cluster-config-file /opt/redis/6380/nodes.conf   #多实例情况下需要修改，例如/6380/
