1.安装依赖包

yum install -y gcc gcc-c++ make zlib zlib-devel pcre pcre-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers  libxslt libxslt-devel libzip

2.下载php7安装

• 这里以php7.3为例，官网下载地址：https://secure.php.net/get/php-7.3.0.tar.gz/from/a/mirror

wget http://cn2.php.net/distributions/php-7.3.0.tar.gz

3.解压、编译安装

tar zxvf php-7.3.0.tar.gz
cd php-7.3.0

#安装
make install

• 编译中遇到的错误

1.Libzip 版本过低或提示reinstall解决方法
yum remove libzip -y

2.configure: error: off_t undefined; check your library configuration
echo '/usr/local/lib64
/usr/local/lib
/usr/lib
/usr/lib64'>>/etc/ld.so.conf&&ldconfig -v

3./usr/local/include/zip.h:59:21: 致命错误：zipconf.h：没有那个文件或目录
cp /usr/local/lib/libzip/include/zipconf.h /usr/local/include/zipconf.h

4.配置

• 在之前编译的源码包中，找到 php.ini-production，复制到/usr/local/php下，并改名为php.ini

[root@MiWiFi-R3P-srv php-7.3.0]# pwd
/usr/local/php-7.3.0
[root@MiWiFi-R3P-srv php-7.3.0]# cp php.ini-production /usr/local/php/etc/php.ini

• 显示错误信息

vim /usr/local/php/php.ini 
修改display_errors = On

• 复制启动脚本

[root@MiWiFi-R3P-srv fpm]# pwd
/usr/local/php-7.3.0/sapi/fpm
[root@MiWiFi-R3P-srv fpm]# cp init.d.php-fpm /etc/init.d/php-fpm 
[root@MiWiFi-R3P-srv fpm]# chmod a+x /etc/init.d/php-fpm

[root@MiWiFi-R3P-srv etc]# pwd
/usr/local/php/etc
[root@MiWiFi-R3P-srv etc]# cp php-fpm.conf.default php-fpm.conf
[root@MiWiFi-R3P-srv etc]# vim php-fpm.conf
修改去掉 pid = run/php-fpm.pid 前面的分号

[root@MiWiFi-R3P-srv php-fpm.d]# pwd
/usr/local/php/etc/php-fpm.d
[root@MiWiFi-R3P-srv php-fpm.d]# cp www.conf.default www.conf
