编译安装了好几次，记录下来：

主要有以下步骤：

1、准备编译环境；

2、下载PHP7 源码包；

3、编译安装；

4、配置；

一、准备编译环境：

准备gcc

sudo yum install git gcc gcc-c++ libxml2-devel pkgconfig openssl-devel bzip2-devel curl-devel libpng-devel libjpeg-devel libXpm-devel freetype-devel gmp-devel libmcrypt-devel mariadb-devel aspell-devel recode-devel autoconf bison re2c libicu-devel

二、下载PHP源码

有两种方式下载：

第一种是 https://www.php.net/releases/ 下载对应版本 ， 下载之后用 tar -zxvf 解压；

第二种是 用git，

git clone https://github.com/php/php-src.git git checkout PHP-7.0.2 ＃换成你想要的版本

三、编译安装

配置脚本：PHP7安装目录在/usr/local/php7下。

./buildconf --force

./configure  --prefix=/usr/local/php7 --with-config-file-path=/usr/local/php7/etc --with-mhash   --with-openssl   --with-mysql=shared,mysqlnd  --with-mysqli=shared,mysqlnd  --with-pdo-mysql=shared,mysqlnd  --enable-gd   --with-iconv   --with-zlib   --enable-zip   --enable-inline-optimization   --disable-debug   --disable-rpath   --enable-shared   --enable-xml   --enable-bcmath   --enable-shmop   --enable-sysvsem   --enable-mbregex   --enable-mbstring   --enable-ftp   --enable-gd-native-ttf   --enable-pcntl   --enable-sockets   --with-xmlrpc   --enable-soap   --without-pear   --with-gettext   --enable-session --with-curl  --with-jpeg   --with-freetype   --enable-opcache  --enable-fpm   --enable-fastcgi   --with-fpm-user=apache  --with-fpm-group=apache --without-gdbm   --with-mcrypt   

编译安装：

make clean && make && make install

四、配置

１、拷贝php.ini 配置文件 ,是生产环境的配置文件：

cp php.ini-development /usr/local/php7/etc/php.ini

2、配置php-fpm

 cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf   
 cp /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf 

3、修改php-fpm.conf

#将pid换一个命名，取消配置的备注 pid = /run/php-fpm/php7-fpm.pid  ＃日志文件 error_log = /var/log/php-fpm/php7-error.log  

４、修改www.conf配置文件，更换监听的端口

＃换成9001 listen = 127.0.0.1:9001 

5、配置服务：

 #建议软链接 
 ln -s /usr/local/php7/sbin/php-fpm /usr/sbin/php7-fpm 
 ln -s /usr/local/php7/bin/php /usr/bin/php  
 vi /usr/lib/systemd/system/php7-fpm.service 
 文件内容为： 
 [Unit] 
 Description=The PHP7 FastCGI Process Manager 
 After=syslog.target network.target  
 [Service] 
 Type=simple PIDFile=/run/php-fpm/php7-fpm.pid 
 ExecStart=/usr/sbin/php7-fpm --nodaemonize --fpm-config /usr/local/php7/etc/php-fpm.conf 
 ExecReload=/bin/kill -USR2 $MAINPID  
 [Install] 
 WantedBy=multi-user.target  

6、启动服务

systemctl enable php7-fpm systemctl start php7-fpm

Ubuntu 16.4 编译安装PHP7

PHP 7.4.3 安装遇到的问题:

 1. Package requirements (oniguruma) were not met:  https://qna.habr.com/q/698309
https://www.limstash.com/en/articles/202002/1539

apt-get install libonig-dev 

2. sqlite3 
apt-get install libsqlite3-dev 

3.正常安装后没有正常生成 gd库
切换到编译源码 php-src/ext ，找到相应的扩展按照phpredis的方式make，将生成的库文件拷贝到 安装目录并且修改配置文件重启 fpm进程

一、安装库文件

apt-get install libkrb5-dev libc-client2007e libc-client2007e-dev libcurl4-openssl-dev libbz2-dev libjpeg-dev libmcrypt-dev libxslt1-dev libxslt1.1 libpq-dev libpng-dev libfreetype6-dev  build-essential make

二、make 配置

./configure \

--prefix=/usr/local/php7 \

--with-config-file-path=/etc/php/7 \

--with-zlib-dir \

--with-freetype-dir \

--enable-mbstring \

--with-libxml-dir=/usr \

--enable-soap \

--enable-calendar \

--with-curl \

--with-mcrypt \

--with-zlib \

--with-gd \

--disable-rpath \

--enable-inline-optimization \

--with-bz2 \

--with-zlib \

--enable-sockets \

--enable-sysvsem \

--enable-sysvshm \

--enable-pcntl \

--enable-mbregex \

--enable-exif \

--enable-bcmath \

--with-mhash \

--enable-zip \

--with-pcre-regex \

--with-pdo-mysql \

--with-mysqli \

--with-mysql-sock=/var/run/mysqld/mysqld.sock \

--with-jpeg-dir=/usr \

--with-png-dir=/usr \

--enable-gd-native-ttf \

--with-openssl \

--with-fpm-user=www-data \

--with-fpm-group=www-data \

--enable-ftp \

--with-imap \

--with-imap-ssl \

--with-kerberos \

--with-gettext \

--with-xmlrpc \

--with-xsl \

--enable-opcache \

--enable-fpm

三、编译安装

make && make install

四、配置

五、设置开机自启动
