准备工作

1 linux centos7下安装

yum install  gcc gcc-c++ make zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel  freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel libxslt-devel -y

​​PHP: Downloads​​  官方下载地址

2 手动安装libiconv-devel（编译三部曲）

默认yum源中缺少libiconv-devel软件包，需要编译安装，用于php的编码转换

[root@localhost tools]# wget -P /tools/  http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.15.tar.gz
[root@localhost tools]# ls
libiconv-1.15.tar.gz  mysql-5.7.33-linux-glibc2.12-x86_64.tar.gz
[root@localhost tools]# tar zxf libiconv-1.15.tar.gz
[root@localhost tools]# cd libiconv-1.15/
[root@localhost libiconv-1.15]# ./configure --prefix=/opt/libiconv
[root@localhost libiconv-1.15]# make && make install

下载安装

国内镜像地址：​​Index of /php/​​

1.下载编译文件

[root@localhost ~]# cd /tools
[root@localhost tools]# wget http://mirrors.sohu.com/php/php-7.3.5.tar.gz

2.编译安装

[root@localhost tools]# wget http://mirrors.sohu.com/php/php-7.3.5.tar.gz
[root@localhost tools]# tar -zxf php-7.3.5.tar.gz
[root@localhost tools]# cd php-7.3.5
[root@localhost php-7.3.5]# ./configure --prefix=/opt/php7.3.5 --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-iconv-dir=/opt/libiconv --with-freetype-dir --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-fpm --enable-mbstring --with-gd --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-soap --enable-short-tags --enable-static --with-xsl --with-fpm-user=nginx --with-fpm-group=nginx --enable-ftp --enable-opcache=no

看到如下提示，说明编译成功了

creating libtool
appending configuration tag "CXX" to libtool

Thank you for using PHP.

config.status: creating php7.spec

进行编译安装

[root@localhost php-7.3.5]# make && make install

配置软连接

[root@localhost php-7.3.5]# ln -s /opt/php7.3.5/ /opt/php

配置PHP，拷贝php配置文件到php默认目录，且改名

[root@localhost php-7.3.5]# cp php.ini-development /opt/php/lib/php.ini

配置FastCGI

[root@localhost php-7.3.5]# cd /opt/php/etc/
[root@localhost etc]# pwd
/opt/php/etc
[root@localhost etc]# ls
pear.conf  php-fpm.conf.default  php-fpm.d
[root@localhost etc]# cp php-fpm.conf.default php-fpm.conf
[root@localhost etc]# cp php-fpm.d/www.conf.default php-fpm.d/www.conf

启动php服务

[root@localhost etc]# /opt/php/sbin/php-fpm
[root@localhost ~]# netstat -tunlp|grep php
tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN      16818/php-fpm: mast 

这样就安装完成了，当然还有更简单的方法安装一个宝塔面板直接可以一键安装！
