This article mainly introduces the relevant knowledge of "how to smoothly upgrade php". The editor shows you the operation process through an actual case. The operation method is simple, fast and practical. I hope this article "how to smoothly upgrade php" can help you solve the problem.

Php smooth upgrade 1. Since it is a smooth upgrade, there is no need to downtime or stop the service, and there is no argument for shutting down the website. In the final restart of the upgrade, the restart is the configuration file loaded by PHP, which does not affect the website you are currently running. 3.php-fpm belongs to FastCgi. Once started, it runs in memory, which has nothing to do with the process of compiling and upgrading.

System: centos6.8

Php environment: php5.3.29

Upgrade version: php5.4.45

Download php address: http://www.php.net/distributi...

Copy the php5.3.29 installation directory config.nice to php-5.4.25

[root@localhost php-5.4.45] # cp / php-5.3.29/config.nice / usr/local/src/php-5.4.45

[root@localhost php-5.4.45] # cd php-5.4.45/

[root@localhost php-5.4.45] #. / config.nice

[root@localhost php-5.4.45] # make ZEND_EXTRA_LIBS='-liconv'

[root@localhost php-5.4.45] # make install

After the upgrade is completed, it is recommended that you execute the command: You may want to add: / usr/local/php5/lib/php to your php.ini include_path/usr/local/src/php-5.4.45/build/shtool install-c ext/phar/phar.phar / usr/local/php5/binln-s-f / usr/local/php5/bin/phar.phar / usr/local/php5/bin/pharInstalling PDO headers: / usr/local/php5/include/php/ext/pdo/ may encounter errors in the installation

Reason: if an error message such as "undefined reference to libiconv_open'" occurs when installing PHP into the system, it means that some environment variables are not grasped in ". / configure". The error occurred when creating the "- o sapi/cli/php" and did not give the iconv library parameters to the link.

The first solution: edit Makefile about 77 lines: EXTRA_LIBS =. -lcrypt adds-liconv at the end, for example: EXTRA_LIBS =. -lcrypt-liconv and then make again.

The second solution:

Make ZEND_EXTRA_LIBS='-liconv'

Ln-s / usr/local/lib/libiconv.so.2 / usr/lib64/

Curl upgrade

Description: curl uses yum by default to install SSL version as NSS, and existing projects need to support OpenSSL.

Current curl version

Phpinfo output information

Download the latest curl: https://curl.haxx.se/download/curl-7.54.1.tar.gz
