2、安装Redis
上传安装包到服务器后进行安装
|
[root@uat2-app-01 software]# tar -xzvf /home/software/redis-3.0.7.tar.gz [root@uat2-app-01 software]# cd redis-3.0.7 [root@uat2-app-01 software]# make PREFIX=/usr/local/redis install 或 [root@uat2-app-01 software]# make MALLOC=libc PREFIX=/usr/local/redis install |
3、配置Redis+Sentinel
|
[root@uat2-app-01 software]# mkdir /usr/local/redis/{db,logs,conf} [root@prd-app-gfs-01 ~]# vi /usr/local/redis/conf/ master_redis.conf #配置redis #主redis配置文件（10.10.3.111） daemonize yes pidfile /var/run/redis-6379.pid port 6379 tcp-backlog 511 timeout 0 tcp-keepalive 0 loglevel notice logfile "/usr/local/redis/logs/logfile-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 /usr/local/redis/db 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 byxf2016 maxclients 10000 maxmemory 1024m appendonly no 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-entries 512 list-max-ziplist-value 64 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 [root@prd-app-gfs-01 ~]# vi /usr/local/redis/conf/slave_redis.conf #从redis配置文件（10.10.3.112/10.10.3.113） daemonize yes pidfile /var/run/redis-6379.pid port 6379 tcp-backlog 511 timeout 0 tcp-keepalive 0 loglevel notice logfile "/usr/local/redis/logs/logfile-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 /usr/local/redis/db slaveof 10.10.3.101 6379 masterauth byxf2016 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 byxf2016 maxclients 10000 maxmemory 1024m appendonly no 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-entries 512 list-max-ziplist-value 64 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 [root@prd-app-gfs-01 ~]# vi /usr/local/redis/conf/sentinel.conf #配置sentinetl #主从sentinel配置文件相同 port 26379 daemonize yes logfile "/usr/local/redis/logs/sentinel.log" dir /tmp sentinel monitor mymaster 10.10.3.101 6379 2 sentinel down-after-milliseconds mymaster 30000 sentinel parallel-syncs mymaster 1 sentinel failover-timeout mymaster 180000 [root@prd-app-gfs-01 ~]# 。/redis-server /usr/local/redis/conf/master_redis.conf & #启动主redis（10.10.3.111） [root@prd-app-gfs-01 ~]# ./redis-server /usr/local/redis/conf/slave_redis.conf & #启动从redis（10.10.3.112/10.10.3.113） [root@prd-app-gfs-01 ~]# ./redis-sentinel /usr/local/redis/conf/sentinel.conf & #启动sentinel（10.10.3.111/112/113） |
问题：
错误：WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.
echo 511 > /proc/sys/net/core/somaxconn
