CentOS7.x 默认php版本与php7.4共存
1、下载php后解压
tar xvzf php-7.4.3.tar.gz cd php-7.4.3
2、安装依赖
yum -y install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel oniguruma oniguruma-devel sqlite-devel
3、编译 默认指定安装目录 /usr/local/php7 默认php.ini目录 /usr/local/php7/etc/php.in 与原有php5.x不冲突
./configure --prefix=/usr/local/php7 --with-config-file-path=/usr/local/php7/etc --enable-fpm --with-fpm-user=nginx --with-fpm-group=nginx --enable-inline-optimization --disable-debug --disable-rpath --enable-shared --enable-soap --with-libxml-dir --with-xmlrpc --with-openssl --with-mcrypt --with-mhash --with-pcre-regex --with-sqlite3 --with-zlib --enable-bcmath --with-iconv --with-bz2 --enable-calendar --with-curl --with-cdb --enable-dom --enable-exif --enable-fileinfo --enable-filter --with-pcre-dir --enable-ftp --with-gd --with-openssl-dir --with-jpeg-dir --with-png-dir --with-zlib-dir --with-freetype-dir --enable-gd-native-ttf --enable-gd-jis-conv --with-gettext --with-gmp --with-mhash --enable-json --enable-mbstring --enable-mbregex --enable-mbregex-backtrack --with-libmbfl --with-onig --enable-pdo --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-zlib-dir --with-pdo-sqlite --with-readline --enable-session --enable-shmop --enable-simplexml --enable-sockets --enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-wddx --with-libxml-dir --with-xsl --enable-zip --enable-mysqlnd-compression-support --with-pear --enable-opcache
make -j && make install
4、初始化配置文件
cp php.ini-production /usr/local/php7/etc/php.ini cp sapi/fpm/init.d.php-fpm /etc/init.d/php7-fpm cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf cp /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf
#php-fpm 端口可在 www.conf 里修改
chmod +x /etc/init.d/php7-fpm
/etc/init.d/php7-fpm start
# php7加入环境变量
ln -s /usr/local/php7/bin/php /usr/local/bin/php7
