Strace Nedir? Strace Kullanımı

Linux/Unix’te bir sürecin (process) yaptığı sistem çağrılarını(syscall) izlemek için kullanabileceğiniz bir araçtır. Ayrıca ptrace, ltrace komutlarını inceleyebilirsiniz.

Sürecin çıktılarını stdout’a, kendi çıktılarını stderr’e yazar. more ile sayfa sayfa görmek istiyorsanız. en basit (primitive) kullanımı aşağıdaki gibidir.

# strace <süreç> 2>&1 | more

1	# strace <süreç> 2>&1 \| more

Strace Parametreleri:

-e parametresi ile sadece bir fonksiyon için çıktı üretebiliriz.

Linux Swap Alanı Temizlemek

Sunucunuzun belleği belirli bir anda ihtiyaçları için RAM yetersiz olduğunda, RAM yerine sabit sürücüden(disk) bir parça, “takas alanı(swap)” kullanmaya başlar.

Linux sistemi üzerinde takas alanı(swap) temizlemek için gerekli zamanlar olabilir. Bunu yapmak için, ilk önce takas alanı (swap) tarafından kullanılan memory alanı kadar yeterli boş hafıza olduğundan emin olmanız gerekir.
Bunu görmek için

# free -m

# free -m

Swap alanı check etmek için:

# swapon -s

1	# swapon -s

[root@omeroner ~]$sudo swapon -s
Filename                                Type            Size    Used    Priority
/dev/dm-1                               partition       524284  0       -1

[root@omeroner ~]$sudo swapon -s

Filename Type Size Used Priority

/dev/dm-1 partition 524284 0 -1

Sonra kullanılan swap alanı free etmek için aşağıdaki komutları çalıştırın:

# swapoff -a
# swapon -a

1 2	# swapoff -a # swapon -a

Sonra bu yaptıktan sonra kullanılıyor ne olduğunu kontrol edin.

# free -m

# free -m

[root@omeroner ~]$free -m

Linux’da Processleri Gizleme (hidepid)

Linux’da Diğer Kullanıcılardan Processleri Gizleme

Yönettiğimiz sistemde tanımlı birçok kullanıcı olabilir. Çoğu kullanıcı ssh ile kaynaklara erişebilir. Fakat Debian/Ubuntu/RHEL/CentOS Linux sunucuya erişen kullanıların kendilerine ait olmayan süreçleri görmesini engelleyebiliriz.

Eğer, Linux kernel version 3.2+ (veya Debian (unstable)/Ubuntu 14.04/RHEL/CentOS v6.5+ üstü) sürümleri kullanıyorsanız, root user dışındaki diğer kullanıcılardan süreçleri(process) gizleyebilirsiniz.

Linux’da Processleri Gizleme işlemi hayatımıza yukarda belirttiğim kernel versiyonu ile hayatımıza giren hidepid ile yapabiliyoruz

hidepid, procfs (/proc) için yeni bir mount seçeneğidir. hidepid seçenekleri aşağıdaki gibidir.

hidepid = 0 (default) Varsayılan seçenek 0’dır. Herkes tüm süreçleri gözlemleyebilir.
hidepid = 1 Etkin,Tüm süreçler gizlidir fakat /proc/<PID> süreç kimliklerini görmek mümkün.
hidepid = 2 Etkin, Tüm süreçler gizlidir ve /proc/<PID> süreç kimliklerini görmek mümkün değil.

# mount -o remount,rw,hidepid=2 /proc

1	# mount -o remount,rw,hidepid=2 /proc

Değişikliğin kalıcı olması için

# vim /etc/fstab
proc /proc proc defaults,hidepid=2 0 0

1 2	# vim /etc/fstab proc /proc proc defaults,hidepid=2 0 0

Belli gruba ayrıcalık tanımlayabiliriz.

# mount -o remount,rw,hidepid=2,gid=groupid /proc

1	# mount -o remount,rw,hidepid=2,gid=groupid /proc

# vim /etc/fstab
proc /proc proc defaults,hidepid=2,gid=admin 0 0

1 2	# vim /etc/fstab proc /proc proc defaults,hidepid=2,gid=admin 0 0

Belli bir dizinde bulunan sıkıştırılmış (*.gzip) dosyaları tespit edip bu dosyaların içinde belli bir patern aramak:

find . -iname '*.gz' -print0 | xargs -0 zgrep PATTERN

1	find . -iname '*.gz' -print0 \| xargs -0 zgrep PATTERN

find . -iname '*.gz' -exec zgrep PATTERN {} +

1	find . -iname '*.gz' -exec zgrep PATTERN {} +

exec find gzip linux
