How to install php 5.3 on centos

To install, first you must tell rpm to accept rpm’s signed by me, then add the yum repository information to yum:

rpm -Uvh http://repo.webtatic.com/yum/centos/5/latest.rpm

Now you can install php by doing:

yum --enablerepo=webtatic install php

Or update an existing installation of php, which will also update all of the other php modules installed:

yum --enablerepo=webtatic update php

Timezone Errors

If you have not set the default timezone for dates, you will get PHP warnings and in some cases fatal errors (e.g. when using the DateTime object). PHP will by default use the system’s timezone if not a fatal error, however either in your application or the php.ini, you should set the setting date.timezone. It’s more ideally set in the application, which should be aware of it’s own timezone setting.

Deprecated Errors

Once you are running the new version, you may get “deprecated” errors in your error logs. This isn’t bad, it just means to tell you that some of the functions you are using are no longer prefered, and may be removed in a future major release. An example of this is the ereg functions. Preg functions are prefered over these, as they are much faster and more powerful, and in all cases do at least the same thing.

If upgrading the functions are not an option, and you would like to hide the deprecated errors from your error log, for example on a production server, just edit your /etc/php.ini file, find the line:

error_reporting  =  E_ALL

and replace to:

error_reporting = E_ALL & ~E_DEPRECATED

PHP 5.2.17

I am also maintaining a PHP 5.2.17 release, so should you prefer to install that (for reasons like incompatibilities or testing), you can force it to install that instead by doing:

yum --enablerepo=webtatic --exclude=php*5.3* update php

Or you can add to the /etc/yum.repos.d/webtatic.repo the line:

exclude=php*5.3*

Linux: find command example

The following examples illustrate typical uses of the command find for finding files on a computer.

 find / -name game
Looks for a file named "game" starting at the root directory (searching all directories including mounted filesystems). The `-name' option makes the search case sensitive. You can use the `-iname' option to find something regardless of case.

find /home -user joe

Find every file under the directory /home owned by the user joe. 

 find /usr -name *stat

Find every file under the directory /usr ending in "stat". 

 find /var/spool -mtime +60

Find every file under the directory /var/spool that was modified more than 60 days ago. 

 find /tmp -name core -type f -print | xargs /bin/rm -f

Find files named core in or below the directory /tmp and delete them. Note that this will work incorrectly if there are any filenames containing newlines, single or double quotes, or spaces. 

 find /tmp -name core -type f -print0 | xargs -0 /bin/rm -f

Find files named core in or below the directory /tmp and delete them, processing filenames in such a way that file or directory names containing single or double quotes, spaces or newlines are correctly handled. The -name test comes before the -type test in order to avoid having to call stat(2) on every file. 

 find . -type f -exec file '{}' \;

Runs `file' on every file in or below the current directory. Notice that the braces are enclosed in single quote marks to protect them from interpretation as shell script punctuation. The semicolon is similarly protected by the use of a backslash, though ';' could have been used in that case also. 

find / \( -perm -4000 -fprintf /root/suid.txt '%#m %u %p\n' \), \

 \( -size +100M -fprintf /root/big.txt '%-10s %p\n' \)

Traverse the filesystem just once, listing setuid files and directories into /root/suid.txt and large files into /root/big.txt. 

 find $HOME -mtime 0

Search for files in your home directory which have been modified in the last twenty-four hours. This command works this way because the time since each file was last modified is divided by 24 hours and any remainder is discarded. That means that to match -mtime 0, a file will have to have a modification in the past which is less than 24 hours ago. 

 find . -perm 664

Search for files which have read and write permission for their owner, and group, but which other users can read but not write to. Files which meet these criteria but have other permissions bits set (for example if someone can execute the file) will not be matched. 

 find . -perm -664

Search for files which have read and write permission for their owner and group, and which other users can read, without regard to the presence of any extra permission bits (for example the executable bit). This will match a file which has mode 0777, for example. 

 find . -perm /222

Search for files which are writable by somebody (their owner, or their group, or anybody else).

 find . -perm /220

 find . -perm /u+w,g+w

 find . -perm /u=w,g=w

All three of these commands do the same thing, but the first one uses the octal representation of the file mode, and the other two use the symbolic form. These commands all search for files which are writable by either their owner or their group. The files don't have to be writable by both the owner and group to be matched; either will do. 

 find . -perm -220

 find . -perm -g+w,u+w

Both these commands do the same thing; search for files which are writable by both their owner and their group. 

 find . -perm -444 -perm /222 ! -perm /111

 find . -perm -a+r -perm /a+w ! -perm /a+x

These two commands both search for files that are readable for everybody (-perm -444 or -perm -a+r), have at least on write bit set (-perm /222 or -perm /a+w) but are not executable for anybody (! -perm /111 and ! -perm /a+x respectively)
