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 "^$|^#" bind 172.18.8.19 protected-mode yes port 6379 tcp-backlog 511 timeout 0 tcp-keepalive 300 daemonize yes supervised no pidfile /var/run/redis_6379.pid loglevel notice logfile "/var/log/redis_6379.log" databases 16 save 900 1 save 300 10 save 60 10000 stop-writes-on-bgsave-error yes rdbcompression yes rdbchecksum yes dbfilename dump_6379.rdb dir /data0/redis_trade slave-serve-stale-data yes slave-read-only yes repl-diskless-sync no repl-diskless-sync-delay 5 repl-disable-tcp-nodelay no slave-priority 100 requirepass Allwelltokok appendonly yes appendfilename "appendonly_6379.aof" appendfsync everysec no-appendfsync-on-rewrite no auto-aof-rewrite-percentage 100 auto-aof-rewrite-min-size 64mb aof-load-truncated yes lua-time-limit 5000 slowlog-log-slower-than 10000 slowlog-max-len 128 latency-monitor-threshold 0 notify-keyspace-events "" hash-max-ziplist-entries 512 hash-max-ziplist-value 64 list-max-ziplist-size -2 list-compress-depth 0 set-max-intset-entries 512 zset-max-ziplist-entries 128 zset-max-ziplist-value 64 hll-sparse-max-bytes 3000 activerehashing yes rename-command FLUSHALL ZYzv6FOBdwflW2nX rename-command EVAL S9UHPKEpSvUJMM rename-command FLUSHDB D60FPVDJuip7gy6l client-output-buffer-limit normal 0 0 0 client-output-buffer-limit slave 256mb 64mb 60 client-output-buffer-limit pubsub 32mb 8mb 60 hz 10 aof-rewrite-incremental-fsync yes
三、redis从配置
root># cat redis_6379.conf |grep -Ev "^$|^#" bind 172.18.8.20 protected-mode yes port 6379 tcp-backlog 511 timeout 0 tcp-keepalive 300 daemonize yes supervised no pidfile /var/run/redis_6379.pid loglevel notice logfile "/var/log/redis_6379.log" databases 16 save 900 1 save 300 10 save 60 10000 stop-writes-on-bgsave-error yes rdbcompression yes rdbchecksum yes dbfilename dump_6379.rdb dir /data0/redis_trade slaveof 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 yes slave-read-only yes repl-diskless-sync no repl-diskless-sync-delay 5 repl-disable-tcp-nodelay no slave-priority 100 requirepass Allwelltokok appendonly yes appendfilename "appendonly_6379.aof" appendfsync everysec no-appendfsync-on-rewrite no auto-aof-rewrite-percentage 100 auto-aof-rewrite-min-size 64mb aof-load-truncated yes 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 rename-command FLUSHALL ZYzv6FOBdwflW2nX rename-command EVAL S9UHPKEpSvUJMM rename-command FLUSHDB D60FPVDJuip7gy6l 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
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 10
source /etc/init.d/functions
REDISPORT=6379
EXEC=/usr/local/bin/redis-server
CLIEXEC=/usr/local/bin/redis-cli
PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/usr/local/redis/etc/redis_${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
