collectd安裝redis插件（二）

按照上一篇文章安裝後，重新開機collectd

/etc/init.d/collectd restart
           

報錯如下：

ERROR: lt_dlopen ("/opt/collectd/lib/collectd/redis.so") failed: file not found. The most common cause for this problem is missing dependencies. Use ldd(1) to check the dependencies of the plugin / shared object.
Stopping collectd:                                         [  OK  ]
Starting collectd: ERROR: lt_dlopen ("/opt/collectd/lib/collectd/redis.so") failed: file not found. The most common cause for this problem is missing dependencies. Use ldd(1) to check the dependencies of the plugin / shared object.
                                                           [  OK  ]
           

按照提示有ldd指令來分析：

ldd /opt/collectd/lib/collectd/redis.so
           

linux-vdso.so.1 =>  (0x00007fffebdd4000)
	libhiredis.so.0.13 => not found
	libdl.so.2 => /lib64/libdl.so.2 (0x00007ff213abd000)
	libc.so.6 => /lib64/libc.so.6 (0x00007ff213729000)
	/lib64/ld-linux-x86-64.so.2 (0x00000032c5600000)
           

原因很明顯，找不到 libhiredis.so.0.13，它位于hiredis解壓後的目錄中。

把這個檔案複制到對應位置：

cp ../hiredis/libhiredis.so /lib64/libhiredis.so.0.13
           

再用ldd指令檢視：

ldd /opt/collectd/lib/collectd/redis.so
           

linux-vdso.so.1 =>  (0x00007fffb4bff000)
	libhiredis.so.0.13 => /lib64/libhiredis.so.0.13 (0x00007f2fe0987000)
	libdl.so.2 => /lib64/libdl.so.2 (0x00007f2fe0783000)
	libc.so.6 => /lib64/libc.so.6 (0x00007f2fe03ee000)
	/lib64/ld-linux-x86-64.so.2 (0x00000032c5600000)
           

依賴已經完整

/etc/init.d/collectd restart
           

Stopping collectd:                                         [  OK  ]
Starting collectd:                                         [  OK  ]
