CentOS “apxs” command not found
apxs is an Apachec extension tool.
I realize that this tool, is by default, not installed under CentOS (or perhaps even RedHat).
To fix this, just install it using yum by:
yum install httpd-devel.i386
Find & Locate
ค้นหา file ใน CentOS หรือ Red Hat
locate FileName
find / – name “FileName”
find / – name “FileName*”
find {DirName} – name “FileName*”
find ./ -type f -name “FileName*”

Which php.ini must i edit to disable functions globaly ?
I want to disable some functions
/root/.etc/misc/php.ini
/usr/lib/kloxophp/zend/etc/php.ini
/usr/local/lxlabs/ext/php/etc/php.ini
/usr/local/lxlabs/kloxo/httpdocs/htmllib/filecore/php.ini
/usr/local/lxlabs/kloxo/httpdocs/htmllib/filecore/lxetc/misc /php.ini
/etc/php.ini
/home/httpd/mydomain.com/php.ini
/home/httpd/mydomain.com/php.ini
Create dnp9.com
# cd /home/apache/conf/domains/
#ls
‘ก็จะเห็นรายชื่อโดเมนต่างๆ ตามด้วย .conf
# vi Domain.com.conf
| <VirtualHost 10.X.X.X:80 > AddDefaultCharset TIS-620 <——เพิ่มตรงนี้ ServerName Domain.com ServerAlias www.Domain.com DocumentRoot “/home/admin/Domain.com/” |
แล้วก็บันทึก
# /etc/init.d/kloxo restart
Create data.dnp9.com
vi etc/sysctl.conf
net.ipv4.icmp_echo_ignore_all=1
to disable
echo 1>/proc/sys/net/ipv4/icmp_echo_ignore_all
to enable
echo 0>/proc/sys/net/ipv4/icmp_echo_ignore_all
2. Find disable_functions and set new list as follows:
3. service httpd restart
