Upgrade the online server php5.3.8 to php5.6.3 and php5.3.8php5.6.3.

Upgrade the online server php5.3.8 to php5.6.3 and php5.3.8php5.6.3.

Server Type CentOS 6.5

Because the project needs to use new features such as php5.4 and above, the current server still uses php5.3.8, so the upgrade is required.

First, connect to the server and shut down the php-fpm service.(In fact, it does not affect, because it is okay to run the program in the memory)Rename/usr/local/php to prevent rollback if the new version fails to be updated.

mv /usr/local/php  /usr/local/php5.3.8

Download the latest php5.6.3 and decompress it.

wget  http://www.php.net/distributions/php-5.6.3.tar.gztar -zxvf  php-5.6.3.tar.gz

Because it is an upgrade, I have installed many php dependency packages and attached my configure configuration parameters first.

./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-fpm-user=www --with-fpm-group=www  --enable-fpm --enable-opcache --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --disable-fileinfo   --with-iconv-dir=/usr/local  --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml   --disable-rpath --enable-bcmath --enable-shmop --enable-exif --enable-sysvsem --enable-inline-optimization --with-curl   --enable-mbregex --enable-mbstring  --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash  --enable-pcntl --enable-sockets --with-xmlrpc --enable-ftp --with-gettext --enable-zip --enable-soap --disable-ipv6  --disable-debug

Note that enabling opcache can cache opcode to improve php performance.

Also -- disable-debug -- disable-ipv6 disable debug ipv6 can improve performance

The first make error occurred.

ext/iconv/.libs/iconv.o: In function `php_iconv_stream_filter_ctor':/home/king/php-5.2.13/ext/iconv/iconv.c:2491: undefined reference to `libiconv_open'collect2: ld returned 1 exit statusmake: *** [sapi/cli/php] Error 1

If an error message such as "undefined reference to libiconv_open" occurs when installing PHP in the system, it means that some environment variable values are not fixed in "./configure. The error occurs when "-o sapi/cli/php" is created. The iconv function parameters to be linked are not provided. Solution: Edit Makefile about 77 rows: EXTRA_LIBS = ..... -Added-liconv to the end of lcrypt, for example: EXTRA_LIBS = ..... -lcrypt-liconv: make it again.

Then, make passed successfully.

Make clean # Clear the obj file generated in the previous compilation. make ZEND_EXTRA_LIBS = '-liconv' make install

The specific parameters of php. ini under configuration optimization can be easily understood by Baidu.
