Linux不能刪除共享內存
在VMware中,CentOS release 6.3 (Final)系統:
[root@localhost ~]# uname -a
Linux localhost.localdomain 2.6.32-279.el6.i686 #1 SMP Fri Jun 22 10:59:55 UTC 2012 i686 i686 i386 GNU/Linux系統中,出現一個問題:
Linux不能刪除共享內存?
[root@localhost ~]# ipcs -m
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x00000000 1835008 root 777 5242880 3 dest
0x00000000 720898 root 777 5242880 1 dest
0x00000000 1114115 root 777 5242880 17 dest
0x00000000 1015812 root 777 5242880 10 dest
0x00000000 1638405 root 777 5242880 12 dest
0x00000000 1540102 root 777 5242880 7 dest
執行ipcrm一直刪除,但卻始終刪除不了。
[root@localhost ~]# ipcrm -m 1835008
[root@localhost ~]# ipcs -m
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x00000000 1835008 root 777 5242880 3 dest
0x00000000 720898 root 777 5242880 1 dest
0x00000000 1114115 root 777 5242880 17 dest
0x00000000 1015812 root 777 5242880 10 dest
0x00000000 1638405 root 777 5242880 12 dest
0x00000000 1540102 root 777 5242880 7 dest
結果還是一樣,刪除不了
這時候的key跟平常不一樣,key的值是0x00000000。找了很多資料,基本上只有幾個原因:1.權限問題;2.進程佔用。
我本身就是root,權限基本上是不沾邊了。

發現php-fpm不正常,很多php-fpm服務說明沒有退出,於是重啓php-fpm服務
[root@localhost seomanagerd]# /etc/init.d/php-fpm restart
Stopping php-fpm: [ OK ]
Starting php-fpm: [ OK ]
再執行
[root@localhost seomanagerd]# ps -aux
php-fpm只剩下幾個了,這時候查看共享內存:
[root@localhost ~]# ipcs -m
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
正常,原因就是:共享內存雖然被刪除了,但進程仍然佔用着共享內存,所以纔出現key爲0x00000000的現象。
[root@localhost ~]# uname -a
Linux localhost.localdomain 2.6.32-279.el6.i686 #1 SMP Fri Jun 22 10:59:55 UTC 2012 i686 i686 i386 GNU/Linux系統中,出現一個問題:
Linux不能刪除共享內存?
[root@localhost ~]# ipcs -m
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x00000000 1835008 root 777 5242880 3 dest
0x00000000 720898 root 777 5242880 1 dest
0x00000000 1114115 root 777 5242880 17 dest
0x00000000 1015812 root 777 5242880 10 dest
0x00000000 1638405 root 777 5242880 12 dest
0x00000000 1540102 root 777 5242880 7 dest
執行ipcrm一直刪除,但卻始終刪除不了。
[root@localhost ~]# ipcrm -m 1835008
[root@localhost ~]# ipcs -m
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x00000000 1835008 root 777 5242880 3 dest
0x00000000 720898 root 777 5242880 1 dest
0x00000000 1114115 root 777 5242880 17 dest
0x00000000 1015812 root 777 5242880 10 dest
0x00000000 1638405 root 777 5242880 12 dest
0x00000000 1540102 root 777 5242880 7 dest
結果還是一樣,刪除不了
這時候的key跟平常不一樣,key的值是0x00000000。找了很多資料,基本上只有幾個原因:1.權限問題;2.進程佔用。
我本身就是root,權限基本上是不沾邊了。

發現php-fpm不正常,很多php-fpm服務說明沒有退出,於是重啓php-fpm服務
[root@localhost seomanagerd]# /etc/init.d/php-fpm restart
Stopping php-fpm: [ OK ]
Starting php-fpm: [ OK ]
再執行
[root@localhost seomanagerd]# ps -aux
php-fpm只剩下幾個了,這時候查看共享內存:
[root@localhost ~]# ipcs -m
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
正常,原因就是:共享內存雖然被刪除了,但進程仍然佔用着共享內存,所以纔出現key爲0x00000000的現象。
