php7的安裝

wget http://am1.php.net/get/php-7.0.4.tar.gz/from/this/mirrortar zvxf php-7.0.4.tar.gzcd php-7.0.4./configure --prefix=/data/php7 --with-config-file-path=/data/php7/etc --with-icu-dir=/usr --with-xsl --enable-fpm --with-fpm-user=www-data --with-fpm-group=www-data --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-iconv-dir --with-freetype-dir=/usr/local/freetype --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-mbstring --enable-intl --enable-pcntl --with-mcrypt --enable-ftp --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --with-gettext --enable-fileinfo --enable-opcache --with-xsl

1、出現錯誤：

Unable to detect ICU prefix or no failed. Please verify ICU install prefix and make sure icu-config works.

解決方案：

yum install -y icu libicu libicu-devel   configure參數添加 --with-icu-dir=/usr

2、出現故障：

configure: error: mcrypt.h not found. Please reinstall libmcrypt.

解決方案：

wget http://softlayer.dl.sourceforge.net/sourceforge/mcrypt/libmcrypt-2.5.8.tar.gztar -zxvf libmcrypt-2.5.8.tar.gzcd /usr/local/src/libmcrypt-2.5.8./configure makemake install

3問題：

configure: error: xslt-config not found. Please reinstall the libxslt >= 1.1.0 distribution

解決：

yum install -y libxslt libxslt-devel libxml2 libxml2-devel  configure加上--with-xsl

出問題解決網站：https://teddysun.com/363.html（非廣告哈，確實幫我大忙了）

假設make時候出現liconv相關錯誤。可進行一下操作

vim Makefile 找到 EXTRA_LIBS 添加 -liconv

最後進行編譯安裝

make && make install

php.ini檔案和php-fpm.conf檔案產生。

cp php.ini-production /usr/local/php7/etc/php.inicd /usr/src/php-7.0.4/sapi/fpmcp init.d.php-fpm /etc/init.d/php-fpmchmod +x /etc/init.d/php-fpmchkconfig --add php-fpmchkconfig php-fpm on

為了php7效能再次提升，能夠參考鳥哥部落格http://www.laruence.com/2015/12/04/3086.html

discuz的php7版本號碼，由於博主第一次做開源。所以裡面的redme文檔沒有寫。

代碼地址：https://code.csdn.net/zzh787272581/dz-yboard-cn/tree/master（代碼僅僅能在php7同意，原因在後面有說明）

裡面主要改動點：

1、將eval去掉。這裡不針對php7去改動，僅僅是博主認為這個函數線上上server不安全。

2、將preg_replace帶有/e 修飾符所有替換成preg_replace_callback 函數，將preg_replace裡面數組形式替換成preg_replace_callback_array;這裡由於用了preg_replace_callback_array,僅僅能在php7下執行。

3、有一些地方寫死了mysql的函數，這裡將所有替換成mysqli的函數進行書寫。

最後貼一張php5.4和php7以下dz首頁的ab壓測圖。機器不好。所以qps不是非常好看。

都是用 ab -n 500 -c http://dz.yboard.cn/

總的來說，效能還是有非常大提升的。
