一、环境介绍

Redis―master   172.18.8.19
Redis―slave   172.18.8.20

二、redis主的配置

#创建redis数据目录mkdir -p /data0/redis_trade#redis主配置文件root># cat redis_6379.conf |grep -Ev "^$|^#"bind 172.18.8.19protected-mode yesport 6379tcp-backlog 511timeout 0tcp-keepalive 300daemonize yessupervised nopidfile /var/run/redis_6379.pidloglevel noticelogfile "/var/log/redis_6379.log"databases 16save 900 1save 300 10save 60 10000stop-writes-on-bgsave-error yesrdbcompression yesrdbchecksum yesdbfilename dump_6379.rdbdir /data0/redis_tradeslave-serve-stale-data yesslave-read-only yesrepl-diskless-sync norepl-diskless-sync-delay 5repl-disable-tcp-nodelay noslave-priority 100requirepass Allwelltokokappendonly yesappendfilename "appendonly_6379.aof"appendfsync everysecno-appendfsync-on-rewrite noauto-aof-rewrite-percentage 100auto-aof-rewrite-min-size 64mbaof-load-truncated yeslua-time-limit 5000slowlog-log-slower-than 10000slowlog-max-len 128latency-monitor-threshold 0notify-keyspace-events ""hash-max-ziplist-entries 512hash-max-ziplist-value 64list-max-ziplist-size -2list-compress-depth 0set-max-intset-entries 512zset-max-ziplist-entries 128zset-max-ziplist-value 64hll-sparse-max-bytes 3000activerehashing yesrename-command FLUSHALL ZYzv6FOBdwflW2nXrename-command EVAL S9UHPKEpSvUJMMrename-command FLUSHDB D60FPVDJuip7gy6lclient-output-buffer-limit normal 0 0 0client-output-buffer-limit slave 256mb 64mb 60client-output-buffer-limit pubsub 32mb 8mb 60hz 10aof-rewrite-incremental-fsync yes

三、redis从配置

root># cat redis_6379.conf |grep -Ev "^$|^#"bind 172.18.8.20protected-mode yesport 6379tcp-backlog 511timeout 0tcp-keepalive 300daemonize yessupervised nopidfile /var/run/redis_6379.pidloglevel noticelogfile "/var/log/redis_6379.log"databases 16save 900 1save 300 10save 60 10000stop-writes-on-bgsave-error yesrdbcompression yesrdbchecksum yesdbfilename dump_6379.rdbdir /data0/redis_tradeslaveof 172.18.8.19 6379   -----从库比主库多这2行配置参数masterauth Allwelltokok   -----从库比主库多这2行配置参数slave-serve-stale-data yesslave-read-only yesrepl-diskless-sync norepl-diskless-sync-delay 5repl-disable-tcp-nodelay noslave-priority 100requirepass Allwelltokokappendonly yesappendfilename "appendonly_6379.aof"appendfsync everysecno-appendfsync-on-rewrite noauto-aof-rewrite-percentage 100auto-aof-rewrite-min-size 64mbaof-load-truncated yeslua-time-limit 5000slowlog-log-slower-than 10000slowlog-max-len 128latency-monitor-threshold 0notify-keyspace-events ""hash-max-ziplist-entries 512hash-max-ziplist-value 64list-max-ziplist-size -2list-compress-depth 0set-max-intset-entries 512zset-max-ziplist-entries 128zset-max-ziplist-value 64hll-sparse-max-bytes 3000activerehashing yesrename-command FLUSHALL ZYzv6FOBdwflW2nXrename-command EVAL S9UHPKEpSvUJMMrename-command FLUSHDB D60FPVDJuip7gy6lclient-output-buffer-limit normal 0 0 0client-output-buffer-limit slave 256mb 64mb 60client-output-buffer-limit pubsub 32mb 8mb 60hz 10aof-rewrite-incremental-fsync yes

四、redis启动脚本

root># cat /etc/init.d/redis_6379 #!/bin/sh## Simple Redis init.d script conceived to work on Linux systems# as it does use of the /proc filesystem.# chkconfig:  2345 90 10source /etc/init.d/functionsREDISPORT=6379EXEC=/usr/local/bin/redis-serverCLIEXEC=/usr/local/bin/redis-cli PIDFILE=/var/run/redis_${REDISPORT}.pidCONF="/usr/local/redis/etc/redis_${REDISPORT}.conf"AUTH="Allwelltokok"BIND_IP='172.18.8.19' start(){     if [ -f $PIDFILE ]  then    echo "$PIDFILE exists, process is already running or crashed"  else    echo "Starting Redis server..."    $EXEC $CONF  fi  if [ "$?"="0" ]   then     echo "Redis is running..."   fi   } stop(){   if [ ! -f $PIDFILE ]  then    echo "$PIDFILE does not exist, process is not running"  else    PID=$(cat $PIDFILE)    echo "Stopping ..."    $CLIEXEC -h $BIND_IP -a $AUTH -p $REDISPORT SHUTDOWN     sleep 1    while [ -x /proc/${PID} ]    do      echo "Waiting for Redis to shutdown ..."      sleep 1    done      echo "Redis stopped"  fi} restart(){  stop  start }status(){   ps -ef|grep redis-server|grep -v grep >/dev/null 2>&1   if [ $? -eq 0 ];then     echo "redis server is running"   else    echo "redis server is stopped"   fi    }  case "$1" in  start)    start    ;;  stop)    stop    ;;       restart)    restart    ;;       status)    status    ;;     *)      echo "Usage: /etc/init.d/redis {start|stop|status|start}" >&2    exit 1 esac

五、启动服务

root># /etc/init.d/redis_6379 start  

查看日志
