測試工具
Redis的驗證
客戶現場,因為有很多Redis的Client, 所以client 設定到 5000 進行模擬.
./redis-benchmark -h 127.0.0.1 -p 6379 -n 1000000 -c 5000 -q
預設值引數進行測試之一
修改一個引數進行測試之二
修改引數的原因:
The TCP backlog setting of 511 cannot be enforced because
/proc/sys/net/core/somaxconn is set to the lower value of 128.
echo 512 > /proc/sys/net/core/somaxconn
再次進行相同的測試
測試大key值.

修改IP_PORT_RAGE和TW_BUCKET後
sysctl -w net.ipv4.ip_local_port_range="10000 20000"
sysctl -w net.ipv4.tcp_max_tw_buckets=100000
sysctl -w net.ipv4.tcp_tw_reuse=0
這樣很容易就會出現錯誤:
Could not connect to Redis at 127.0.0.1:6379: Cannot assign requested address
所以建議修改為:
sysctl -w net.ipv4.ip_local_port_range="1025 65530"
sysctl -w net.ipv4.tcp_max_tw_buckets=10000
sysctl -w net.ipv4.tcp_tw_reuse=0
測試間隙檢視:
netstat -an |grep 6379 |awk '{print $6}' |sort|uniq -c
10000 ESTABLISHED
2 LISTEN
9996 TIME_WAIT
會發現很多類似的情況
