pecl install apc isn't working. shtool does not exist

问题

I am an absolute newbie…didn't learn about SSh till an hour ago and got my first VPS 2 hours ago. Still learning!

So I'm installing MediaWiki and need to add APC extension. But having a lil trouble. Any ideas/tips?

[root@www ~]# pecl install apc`
downloading APC-3.1.13.tgz ...

shtool at '/var/tmp/APC/build/shtool' does not exist or is not executable.
Make sure that the file exists and is executable and then rerun this script.`

回答1:

Remove noexec flag from /var/tmp directory use the following command

mount -o remount,exec /var/tmp/

You can use the same command to add the noexec flag back

mount -o remount,noexec /var/tmp/

Try this, copied from http://blog.litespeedtech.com/2013/04/05/trouble-shooting-pecl-install-doesnt-work/

A more appropriate workaround is to point PECL’s temp_dir to a partition or path that allows execution:
mkdir /root/tmp
pecl config-set temp_dir /root/tmp
or
pear config-set temp_dir /root/tmp
(There is a known bug where pecl config-set does not work but pear config-set does. If this is the case for you, simply use the PEAR config command. PECL will use PEAR when doing the install.)

This workaround preserves any security benefit from having /tmp set as noexec, but also allows PECL installs.
