PHP5.5.0 is compiled and installed in source code to solve the problem of 502 error returned when curl_exec accesses HTTPS. php5.5.0curl _ exec

Recently, I encountered a strange problem. When PHP uses curl_exec to access the HTTPS webpage, the error 502 is returned. If there is no problem accessing the HTTP webpage, echo phpinfo () is used. Check that openssl and curl are supported, I found a lot of information on the Internet and did not solve it.

[root@www ~]# php -VFailed loading /usr/local/zend/ZendOptimizer.so:  /usr/local/zend/ZendOptimizer.so: undefined symbol: zend_throw_exception_internalPHP Warning:  PHP Startup: memcache: Unable to initialize moduleModule compiled with module API=20060613PHP    compiled with module API=20090626These options need to match in Unknown on line 0PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/openssl.so' - /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/openssl.so: undefined symbol: zend_parse_parameters_none in Unknown on line 0

Run # php-V to check whether openssl. so fails to be loaded. It seems that it must be related to the openssl library. The openssl library is re-installed, and the problem persists. The reason is that zend is used in the openssl library. The above prompt shows that zend Library also reports an error. It is estimated that the zend library has to be re-installed for processing. This is troublesome. If you don't want to use the source code to compile php, just do it.

Some errors may occur during the installation process. The following is what I encountered during installation. The environment is different and the problems encountered by each machine are also different.

1. An error occurs. xpm. h not found.

# Yum install libXpm-devel // note that x is in uppercase
# Yum install libXext-devel // note that x is in uppercase

2. gmp. h not found

# Yum install gmp

# Yum install gmp-devel

3. error: utf8_mime2text () has new signature, but U8T_CANONICAL is missing. This shocould not happen

Php installation is complete. After testing the php page, the problem persists. Finally, I checked it carefully. The phpinfo () function shows the version 5.2.17, And I installed 5.5.0, apparently, the nginx server is still using

The old php did not enable the latest php compiled and installed. I looked for it. The old php Directory is/usr/local/bin/php, the newly installed php Directory is/usr/bin/php.

Why not use the latest php? It is obviously related to the Environment Variable PATH. Run the env command to see

PATH =/usr/local/mysql/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin: /usr/bin:/root/bin

We can modify the/etc/profile file and put the last line of the file:

Export PATH =/usr/local/mysql/bin: $ PATH

Change

Export PATH =/usr/local/mysql/bin:/usr/bin: $ PATH

Then

# Cd/etc

# Source profile reload the profile file

Finally, test the php file. curl_exec can access the https file and obtain the data.
