大家帮帮忙!!!
这是我web服务器,在线人数为400人,我的服务器现在负载很高,但查没什么异常,就是负载很高,我的服务器最高load average不能超过八,我不知道是流量太大了还是别的原因,请大家帮帮忙,应该怎么来处理呢?
会不会是被攻击装了 rootkit,如果真的是被装了rootkit,该怎么查找呢,小弟感激不尽,各位大虾多多指教呀 top - 15:31:26 up 59 days, 3:35, 1 user, load average: 12.02, 10.38, 9.72 Tasks: 195 total, 5 running, 190 sleeping, 0 stopped, 0 zombie Cpu(s): 3.5% us, 12.5% sy, 0.0% ni, 58.5% id, 25.4% wa, 0.1% hi, 0.0% si Mem: 4137836k total, 1607424k used, 2530412k free, 176496k buffers Swap: 8193108k total, 144k used, 8192964k free, 535904k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1788 daemon 15 0 16084 8512 3040 D 5.3 0.2 0:08.52 httpd 1960 daemon 15 0 16480 8936 3036 D 5.3 0.2 0:04.61 httpd 2014 daemon 15 0 16104 8560 3028 R 5.3 0.2 0:07.96 httpd 1848 daemon 16 0 16288 8760 3036 D 4.3 0.2 0:14.83 httpd 1900 daemon 18 0 16708 9120 3028 D 4.0 0.2 0:10.51 httpd 1964 daemon 18 0 15676 8056 3024 R 4.0 0.2 0:07.63 httpd 1918 daemon 18 0 14796 7016 2788 D 3.7 0.2 0:14.98 httpd 1841 daemon 18 0 16096 8552 3036 D 3.3 0.2 0:02.34 httpd 2134 daemon 18 0 14936 7128 2804 D 3.3 0.2 0:00.39 httpd 1958 daemon 18 0 14932 7040 2796 R 3.0 0.2 0:10.35 httpd 1984 daemon 18 0 15288 7688 2964 R 3.0 0.2 0:07.52 httpd 1993 daemon 18 0 15748 8080 2956 D 3.0 0.2 0:10.27 httpd 1783 daemon 15 0 16156 8624 3032 S 2.7 0.2 0:00.49 httpd 72 root 15 0 0 0 0 S 2.0 0.0 161:10.97 kswapd0 2020 daemon 15 0 16448 8912 3032 S 1.3 0.2 0:00.25 httpd 2087 daemon 16 0 16148 8600 3032 S 1.3 0.2 0:00.24 httpd 1891 daemon 16 0 16056 8484 3032 S 1.0 0.2 0:00.14 httpd 1953 daemon 15 0 15624 8024 2956 S 1.0 0.2 0:00.03 httpd 2064 daemon 15 0 15764 8208 3028 S 1.0 0.2 0:00.11 httpd 2080 daemon 15 0 16172 8600 3028 S 1.0 0.2 0:00.13 httpd 2105 daemon 16 0 16412 8828 3032 S 1.0 0.2 0:00.15 httpd 31680 root 16 0 2932 1076 744 R 0.7 0.0 0:10.05 top 2133 daemon 15 0 16176 8600 3020 S 0.7 0.2 0:00.20 httpd 1884 daemon 16 0 17336 9816 3032 S 0.3 0.2 0:00.46 httpd 1943 daemon 15 0 16124 8500 3028 S 0.3 0.2 0:00.21 httpd 2053 daemon 15 0 17304 9796 3044 S 0.3 0.2 0:00.39 httpd 2055 daemon 16 0 15332 7660 2948 S 0.3 0.2 0:00.03 httpd 2097 daemon 15 0 15532 7860 2956 S 0.3 0.2 0:00.06 httpd 2102 daemon 15 0 16112 8472 3028 S 0.3 0.2 0:00.10 httpd 1 root 16 0 2448 556 476 S 0.0 0.0 0:17.34 init 2 root RT 0 0 0 0 S 0.0 0.0 0:00.76 migration/0 3 root 34 19 0 0 0 S 0.0 0.0 4:00.75 ksoftirqd/0 4 root RT 0 0 0 0 S 0.0 0.0 0:00.53 migration/1 |
