本文以php 7.3.10版本为例
安装包存放路径 /usr/local/src/
下载：
[root@linux src]# wget https://www.php.net/distributions/php-7.3.10.tar.bz2
解压：
[root@linux src]# tar -jxvf php-7.3.10.tar.bz2
编译安装：
进入目录 cd php-7.3.10.tar.bz2
配置编译参数：
./configure --prefix=/usr/local/php-fpm --with-config-file-path=/usr/local/php-fpm/etc --enable-fpm --with-fpm-user=php-fpm --with-fpm-group=php-fpm --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-pdo-mysql=/usr/local/mysql --with-mysql-sock=/tmp/mysql.sock --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-ftp --enable-mbstring --enable-exif --with-pear --with-curl --with-openssl
编译： make
安装：make install
拷贝配置文件php.ini-development到php程序安装目录：
[root@linux php-7.3.10]# cp php.ini-development /usr/local/php-fpm/etc/php.ini
拷贝启动脚本到/etc/init.d/目录：
[root@linux php-7.3.10]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
进入php安装目录下的/etc目录重命名配置文件：
[root@linux php-7.3.10]# cd /usr/local/php-fpm/etc/
[root@linux etc]# cp php-fpm.conf.default php-fpm.conf
[root@linux etc]# cd php-fpm.d/
[root@linux php-fpm.d]# cp www.conf.default www.conf
添加php启动脚本到系统服务：
[root@linux php-fpm.d]# chkconfig --add php-fpm
[root@linux php-fpm.d]# chkconfig php-fpm on
[root@linux php-fpm.d]# chmod 755 /etc/init.d/php-fpm
创建php用户：
[root@linux php-fpm.d]# useradd php-fpm
启动php：
[root@linux php-fpm.d]# service php-fpm start
编译安装php报错解决方法：
报错1：checking for gcc… no
解决：yum -y install gcc
报错2：error: libxml2 not found
解决：yum install -y libxml2-devel
报错3：error: Cannot find OpenSSL’s
解决：yum install -y openssl-devel
报错4：error: cURL version 7.15.5 or later is required
解决：yum install -y libcurl-devel
报错5：configure: error: jpeglib.h not found
解决：yum install -y libjpeg-turbo-devel
报错6：configure: error: png.h not found
解决：yum install -y libpng-devel
报错7：configure: error: freetype-config not found
解决：yum install -y freetype-devel
报错8：configure: error: wrong mysql library version or lib not found
该错误表示当前安装的MySQL/MariaDB版本过高，下载个低版本的MySQL包将编译参数含有MySQL/MariaDB的路径改为低版本MySQL程序目录即可，无需安装低版本MySQL
解决：
1.下载MySQL5.6二进制包：
[root@linux ~]# cd /usr/local/src/
[root@linux src]# wget http://mirrors.163.com/mysql/Downloads/MySQL-5.6/mysql-5.6.43-linux-glibc2.12-x86_64.tar.gz
2.解压：
[root@linux src]# tar -zxvf mysql-5.6.43-linux-glibc2.12-x86_64.tar.gz
3.移动到/usr/local/目录下重命名为mysql5.6：
[root@linux src]# mv mysql-5.6.43-linux-glibc2.12-x86_64.tar.gz /usr/local/mysql5.6
4.更改编译参数中 - -with-mysql，- -with-mysqli，- -with-pdo-mysql指向的路径为MySQL5.6目录：
./configure --prefix=/usr/local/php-fpm --with-config-file-path=/usr/local/php-fpm/etc --enable-fpm --with-fpm-user=php-fpm --with-fpm-group=php-fpm –with-mysql=/usr/local/mysql5.6 --with-mysqli=/usr/local/mysql5.6/bin/mysql_config --with-pdo-mysql=/usr/local/mysql5.6 --with-mysql-sock=/tmp/mysql.sock --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-ftp --enable-mbstring --enable-exif --with-pear --with-curl --with-openssl
报错9：ERROR: [pool www] cannot get uid for user ‘php-fpm’
创建编译参数中指定的php用户即可
解决：useradd php-fpm
