服務器類型 CentOS 6.5

因為項目要用到php5.4以上的新功能 目前服務器還是用php5.3.8版本 所以升級版本就非常需要了。

首先 連上服務器 先把 php-fpm服務關閉（其實不影響的，因為程序在內存里面跑 不關也沒事的） 然后 先把 /usr/local/php 重命名 以防止如果新版本更新失敗 回滾

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

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

./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

還有 --disable-debug --disable-ipv6 關閉 debug ipv6 可以提升性能

第一次make 出錯了

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

網上找到解決辦法

在安裝 PHP 到系統中時要是發生「undefined reference to libiconv_open'」之類的錯誤信息，那表示在「./configure 」沒抓好一些環境變數值。錯誤發生點在建立「-o sapi/cli/php」是出錯，沒給到要 link 的 iconv 函式庫參數。 解決方法：編輯Makefile 大約77 行左右的地方: EXTRA_LIBS = ..... -lcrypt 在最后加上 -liconv，例如: EXTRA_LIBS = ..... -lcrypt -liconv 然后重新再次 make 即可。

然后 重新make 順利通過了

make clean  #清除上次編譯生成的 obj文件make ZEND_EXTRA_LIBS='-liconv'make install
