Centos 7下编译安装PHP7.2（与Nginx搭配的安装方式）
一、下载源码包
百度云网盘下载地址：https://pan.baidu.com/s/1li4oD3qjvFyIaEZQt2NVRg
提取码：4yde
二、安装php依赖组件
yum -y install wget vim pcre pcre-devel openssl openssl-devel libicu-devel gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel ncurses ncurses-devel curl curl-devel krb5-devel libidn libidn-devel openldap openldap-devel nss_ldap jemalloc-devel cmake boost-devel bison automake libevent libevent-devel gd gd-devel libtool* libmcrypt libmcrypt-devel mcrypt mhash libxslt libxslt-devel readline readline-devel gmp gmp-devel libcurl libcurl-devel openjpeg-devel
三、创建用户和组
groupadd www
useradd -g www www
四、设置变量并开始源码编译
cp -frp /usr/lib64/libldap* /usr/lib/
./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --enable-fpm --with-fpm-user=www --with-fpm-group=www --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --enable-mysqlnd-compression-support --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-mbstring --enable-intl --with-libmbfl --enable-ftp --with-gd --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --with-gettext --disable-fileinfo --enable-opcache --with-pear --enable-maintainer-zts --with-ldap=shared --without-gdbm
五、开始编译
make && make install
六、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
修改 php.ini 相关参数：
vim /usr/local/php/etc/php.ini
expose_php = Off short_open_tag = ON max_execution_time = 300 max_input_time = 300 memory_limit = 128M post_max_size = 32M date.timezone = Asia/Shanghai mbstring.func_overload=2 extension = "/usr/local/php/lib/php/extensions/no-debug-zts-20170718/ldap.so" #OPcache 缓存 [opcache] zend_extension=/usr/local/php/lib/php/extensions/no-debug-zts-20170718/opcache.so opcache.memory_consumption=128 opcache.interned_strings_buffer=8 opcache.max_accelerated_files=4000 opcache.revalidate_freq=60 opcache.fast_shutdown=1 opcache.enable_cli=1
七、配置www.conf
listen = /var/run/www/php-cgi.sock listen.owner = www listen.group = www listen.mode = 0660 listen.allowed_clients = 127.0.0.1 pm = dynamic listen.backlog = -1 pm.max_children = 180 pm.start_servers = 50 pm.min_spare_servers = 50 pm.max_spare_servers = 180 request_terminate_timeout = 120 request_slowlog_timeout = 50 slowlog = var/log/slow.log
八、创建php-cgi.sock存放目录
mkdir /var/run/www/ chown -R www:www /var/run/www
九、配置php-fpm.conf
vim /usr/local/php/etc/php-fpm.conf
取下以下注释并填写完整路径：
pid = /usr/local/php/var/run/php-fpm.pid
至此php7已经安装完成。
十、创建system系统单元文件php-fpm启动脚本：
vim /usr/lib/systemd/system/php-fpm.service
添加如下变量内容：
[Unit] Description=The PHP FastCGI Process Manager After=syslog.target network.target [Service] Type=simple PIDFile=/usr/local/php/var/run/php-fpm.pid ExecStart=/usr/local/php/sbin/php-fpm --nodaemonize --fpm-config /usr/local/php/etc/php-fpm.conf ExecReload=/bin/kill -USR2 $MAINPID [Install] WantedBy=multi-user.target
启动php-fpm服务并加入开机自启动：
systemctl enable php-fpm.service systemctl restart php-fpm.service
