discuz的php7版本号

Posted 2020-09-28 clnchanpin

php7的安装

wget http://am1.php.net/get/php-7.0.4.tar.gz/from/this/mirror
tar zvxf php-7.0.4.tar.gz
cd 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、出现错误：

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

解决方法：

yum install -y icu libicu libicu-devel   configure參数添加 --with-icu-dir=/usr

2、出现故障：

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

解决方法：

wget http://softlayer.dl.sourceforge.net/sourceforge/mcrypt/libmcrypt-2.5.8.tar.gz
tar -zxvf libmcrypt-2.5.8.tar.gz
cd /usr/local/src/libmcrypt-2.5.8
./configure 
make
make install

3问题：

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

解决：

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

出问题解决站点：https://teddysun.com/363.html（非广告哈，确实帮我大忙了）

假设make时候出现liconv相关错误。可进行一下操作

vim Makefile 找到 EXTRA_LIBS 添加 -liconv

最后进行编译安装

make && make install

php.ini文件和php-fpm.conf文件生成。

cp php.ini-production /usr/local/php7/etc/php.ini
cd /usr/src/php-7.0.4/sapi/fpm
cp init.d.php-fpm /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm
chkconfig --add php-fpm
chkconfig php-fpm on

为了php7性能再次提升，能够參考鸟哥博客http://www.laruence.com/2015/12/04/3086.html

discuz的php7版本号，由于博主第一次做开源。所以里面的redme文档没有写。

代码地址：https://code.csdn.net/zzh787272581/dz-yboard-cn/tree/master（代码仅仅能在php7同意，原因在后面有说明）

里面主要改动点：

1、将eval去掉。这里不针对php7去改动，仅仅是博主认为这个函数在线上server不安全。

2、将preg_replace带有/e 修饰符所有替换成preg_replace_callback 函数，将preg_replace里面数组形式替换成preg_replace_callback_array;这里由于用了preg_replace_callback_array,仅仅能在php7下执行。

3、有一些地方写死了mysql的函数，这里将所有替换成mysqli的函数进行书写。

最后贴一张php5.4和php7以下dz首页的ab压測图。机器不好。所以qps不是非常好看。

都是用 ab -n 500 -c http://dz.yboard.cn/
