在一個超級古老的機器上mount 了一個nfs, 但是nfs server移除以後就沒有辦法 umount 這個目錄了
umount /backup
報錯如下：
nfs umount: /backup: is busy
怎麼辦呢？
google了一下，使用如下命令可以幹掉
Solaris 2.6 and Solaris 7: umount -o force /mount-point
試用了一下， 還是報錯
不過df -k的時候 發現已經很順暢了，感覺已經去掉了
當然還有另一種辦法
try following ...
unshare /backup
umount /backup
沒有測試過，等下次有機會測試一下
記錄一下備忘！
發現一個oracle exp的方法不錯，就是用file方式。記錄一下備查

http://blogs.sun.com/mandalika/entry/mounting_windows_ntfs_on_open
臨時需要將一個老舊的Solaris2.7上面的數據備份出來，但是這個Sun的server不支持USB,如何處理呢？
想了一個辦法NFS, NFS是sun開發的，估計應該支持，所以找了一個RedHat的server做個NFS server, 這個Solaris nfs方式mount上去
參考鳥哥的nfs server的設定：
RedHat端：
[oracle@oracle03 mnt_usb]$ cat /etc/exports
/mnt_usb *(rw,no_root_squash)
[oracle@oracle03 mnt_usb]$
/mnt_usb是server機器的一個目錄文件
對任何機器都開放
當然前提是server端已經安裝了nfs server的軟件：
/etc/init.d/portmap restart
/etc/init.d/nfs start
驗證：
netstat –ultn
netstat -ultn |grep 111
netstat -ultn |grep 2049
rpcinfo -p localhost
因為沒有設置防火牆，所以沒有安全方面的問題，如果你有，自己檢查一下
如果上述都正常，成功一半了
另一半在Soaris這裡
相對簡單：
root權限
建立一個目錄作為mount的節點：
# mkdir /backup
# mount -F nfs -o rw 172.16.12.24:/mnt_usb /backup
如果沒有報錯就說明成功了！
做一個備份的測試
test>tar cvf - ivantest |gzip -c >/backup/www1/ivantest.tar.gz
ivantest/
ivantest/a.txt
test>
沒有問題，從server哪裡可以看到，解壓也成功了
現有一個測試文本

第10行是什麼呢？

記錄一下，這個腳本對於大文本處理相當有用！
嘗試在solaris10下編譯apache, 儘管已經下載了gcc但是還是不能通過
報錯“make: can not found”
手工運行一把，確實如此，怎麼辦呢？google
發現soalris下確實已經有了gcc和make的program,但是位置沒有在/usr/bin or /sbin/下
gcc 在這裏：
bash-3.00# cd /usr/sfw/bin
bash-3.00# ./gcc -v
Reading specs from /usr/sfw/lib/gcc/sparc-sun-solaris2.10/3.4.3/specs
Configured with: /sfw10/builds/build/sfw10-patch/usr/src/cmd/gcc/gcc-3.4.3/configure --prefix=/usr/sfw --with-as=/usr/ccs/bin/as --without-gnu-as --with-ld=/usr/ccs/bin/ld --without-gnu-ld --enable-languages=c,c++ --enable-shared
Thread model: posix
gcc version 3.4.3 (csl-sol210-3_4-branch+sol_rpath)
bash-3.00#
bash-3.00# cd /usr/ccs/bin
bash-3.00# ./make
make: Fatal error: No arguments to build
不熟悉solaris， 發現沒有default home directory, 只好把加載到 /etc/profile文件中
…
PATH=$PATH:/usr/ccs/bin:/usr/sfw/bin
export PATH
…
從新configure;make ;make install

| You now have successfully built and installed the |
| Apache 1.3 HTTP server. To verify that Apache actually |
| works correctly you now should first check the |
| (initially created or preserved) configuration files |
| |
| /user/local/apache/conf/httpd.conf
| |
| and then you should be able to immediately fire up |
| Apache the first time by running: |
| |
| /user/local/apache/bin/apachectl start

ok, 記錄一下，備忘！
最近在公司整理一個sun 450的服務器，從新安裝solaris 10, 居然可以成功的安裝10年前的Server， 進而想會不會有編譯環境呢？
gcc了一下沒有，我愛想在上面做的開發啥的，怎麼辦呢？google
發現sun 免費發放gcc的compliers
安裝說明參考
http://cooltools.sunsource.net/gcc/4.2.0/install.html
我的實驗：
bash-3.00# ls
SUNW0scgfss421.tar.bz2 SUNWgccfss421.tar.bz2
bash-3.00# /bin/bunzip2 -c SUNWgccfss421.tar.bz2 |/bin/tar xf -
bash-3.00# /bin/bunzip2 -c SUNW0scgfss421.tar.bz2 |/bin/tar xf -
bash-3.00# pwd
/usr/local/gcc/bin
bash-3.00# ls
ats gccbug
bit gcov
c++ sparc-sun-solaris2.10-c++
cpp sparc-sun-solaris2.10-g++
discover sparc-sun-solaris2.10-gcc
g++ sparc-sun-solaris2.10-gcc-4.2.1
gcc
bash-3.00#
bash-3.00# ./gcc
gcc: no input files
bash-3.00#
參考Advanced Programming in the UNIX 2ed
寫個小例子測試一下：
bash-3.00# cat test.c
#include<stdio.h>
#include<dirent.h>
int main(int argc, char *argv[])
{
DIR *dp;
struct dirent *dirp;
if(argc != 2)
{
printf("usage: ls directory_name \n");
return 1;
}
if((dp = opendir(argv[1]))== NULL)
printf("can't open %s", argv[1]);
while((dirp = readdir(dp)) !=NULL)
printf("%s \n", dirp->d_name);
closedir(dp);
//exit(0);
return 0;
}
bash-3.00#
bash-3.00# /usr/local/gcc/bin/gcc -o test test.c
bash-3.00#
bash-3.00# ./test
usage: ls directory_name
bash-3.00# ./test .
.
..
test.c
test.o
test
core
bash-3.00#
貌似可以了， 記錄一下備忘！
