centos编译安装php7

1，安装依赖包：

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 zlib zlib-devel glibc glibc-devel glib2 glib2-devel ncurses curl gdbm-devel db4-devel libXpm-devel libX11-devel gd-devel gmp-devel expat-devel xmlrpc-c xmlrpc-c-devel libicu-devel libmcrypt-devel libmemcached-devel libzip

2，下载安装包并解压： 创建用户和组 groupadd www useradd -g www www wget http://php.net/distributions/php-7.3.2.tar.gz tar -zxvf php-7.3.2.tar.gz cd php-7.3.2

3，开始源码编译：

./configure \ --prefix=/usr/local/php\ --enable-fpm\ --with-fpm-user=www\ --with-fpm-group=www\ --with-config-file-path=/usr/local/php/conf\ --disable-rpath\ --enable-soap\ --with-libxml-dir\ --with-xmlrpc\ --with-openssl\ --with-mhash\ --with-pcre-regex\ --with-zlib\ --enable-bcmath\ --with-bz2\ --enable-calendar\ --with-curl\ --enable-exif\ --with-pcre-dir\ --enable-ftp\ --with-gd\ --with-openssl-dir\ --with-jpeg-dir\ --with-png-dir\ --with-zlib-dir\ --with-freetype-dir\ --enable-gd-jis-conv\ --with-gettext\ --with-gmp\ --with-mhash\ --enable-mbstring\ --with-onig\ --with-mysqli=mysqlnd\ --with-pdo-mysql=mysqlnd\ --with-zlib-dir\ --with-readline\ --enable-shmop\ --enable-sockets\ --enable-sysvmsg\ --enable-sysvsem \ --enable-sysvshm \ --enable-wddx\ --with-libxml-dir\ --with-xsl\ --enable-zip\ --with-pear

之后（次步容易出现问题）

make -j 4 && make install

4，安装后配置

/usr/local/php/bin/php -v 环境变量 PATH=$PATH:/usr/local/php/bin export PATH

5，完成安装后配置php.ini文件：

cp php.ini-development /usr/local/php/etc/php.ini cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf

加入启动服务 cp sapi/fpm/php-fpm.service /usr/lib/systemd/system/php-fpm.service

启动php-fpm systemctl start php-fpm.service

查看是否启动成功： ps aux | grep php-fpm
