一、下载php7.3的源码
https://www.php.net/downloads.php
下载php-7.3.4.tar.gz
二、安装gcc，gcc-c++，kernel-devel
yum -y install gcc gcc-c++ kernel-devel
三、安装php需要的依赖库
yum -y install wget pcre pcre-devel openssl openssl-devel libicu-devel 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
四、创建用户和组，并解压
groupadd www
useradd -g www www
tar xf php-7.3.4.tar.gz
cd php-7.3.4
五、进行编译安装
php的路径 --prefix 和配置文件 --with-config-file-path 路径大家可以自行设置
./configure --prefix=/data/nmp/php \
--with-config-file-path=/data/nmp/php/etc \
--with-fpm-user=www \
--with-fpm-group=www \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd \
--with-iconv-dir \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--with-zlib \
--with-libxml-dir \
--with-ldap=shared \
--with-gdbm \
--with-pear \
--with-gettext \
--with-curl \
--with-xmlrpc \
--with-openssl \
--with-mhash \
--with-gd \
--enable-fpm \
--enable-mysqlnd \
--enable-mysqlnd-compression-support \
--enable-xml \
--enable-rpath \
--enable-bcmath \
--enable-shmop \
--enable-sysvsem \
--enable-inline-optimization \
--enable-mbregex \
--enable-mbstring \
--enable-intl \
--enable-ftp \
--enable-gd-jis-conv \
--enable-pcntl \
--enable-sockets \
--enable-zip \
--enable-soap \
--enable-fileinfo \
--enable-opcache \
--enable-maintainer-zts \
编译安装
make -j 4 && make install
上面的步骤有可能出现的问题：
1、configure: WARNING: unrecognized options: --with-mcrypt, --with-libmbfl, --enable-gd-native-ttf
说明上面的配置参数已经弃用了，删除即可。
2、configure: error: DBA: Could not find necessary header file(s).
安装下 yum install gdbm-devel
3、configure: error: Cannot find ldap libraries in /usr/lib
拷贝下文件 cp -frp /usr/lib64/libldap* /usr/lib/
4、configure: error: off_t undefined; check your library configuration
进行如下操作：
vi /etc/ld.so.conf
# 添加如下几行
/usr/local/lib64
/usr/local/lib
/usr/lib
/usr/lib64
# 保存退出
:wq
# 使之生效
ldconfig -v
5、configure: error: Please reinstall the libzip distribution
在 https://libzip.org/download/ 下载源码，进行安装
tar xf libzip-1.5.2.tar.gz
cd libzip-1.5.2
mkdir build && cd build && cmake .. && make && make install
6、CMake 3.0.2 or higher is required. You are running version 2.8.12.2
说明你的cmake版本过低，需要重新安装
先删除原有cmake
yum remove cmake
在 https://cmake.org/download/ 下载源码
tar xf cmake-3.14.3.tar.gz
cd cmake-3.14.3
./bootstrap && make && make install
然后修改 vi /etc/profile，并加入如下内容
PATH=/usr/local/bin:$PATH
export PATH
source /etc/profile
六、配置php.ini文件
具体的路径，大家可自行修改。
cp php.ini-development /data/nmp/php/etc/php.ini
cp /data/nmp/php/etc/php-fpm.conf.default /data/nmp/php/etc/php-fpm.conf
cp /data/nmp/php/etc/php-fpm.d/www.conf.default /data/nmp/php/etc/php-fpm.d/www.conf
配置php.ini文件
max_execution_time = 120
max_input_time = 120
memory_limit = 1024M
post_max_size = 128M
date.timezone = PRC
extension_dir = "/data/nmp/php/lib/php/extensions/no-debug-zts-20180731"
七、配置Systemd服务
其实php-fpm.service文件php已经帮我们配置好了，只需要我们复制到指定位置，并启用就行了。
cp sapi/fpm/php-fpm.service /usr/lib/systemd/system/
php-fpm.service文件内容如下：
[Unit]
Description=The PHP FastCGI Process Manager
After=network.target [Service]
Type=simple
PIDFile=/data/nmp/php/var/run/php-fpm.pid
ExecStart=/data/nmp/php/sbin/php-fpm --nodaemonize --fpm-config /data/nmp/php/etc/php-fpm.conf
ExecReload=/bin/kill -USR2 $MAINPID
PrivateTmp=true [Install]
WantedBy=multi-user.target
启用php-fpm.service
systemctl enable php-fpm.service
启动php-fpm
systemctl start php-fpm.service
