centos就会将我们刚刚下载的PHP7解压到当前目录。ls查看我们会看到一个php7的文件夹。

安装依赖包

yum install -y libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel

打开php下载页
//www.php.net/downloads.php

最后通过wget下载这个地址里解析出来的文件就可以了。
也可以去github上找 php下载

cd /usr/local/src/
wget //www.php.net/distributions/php-7.3.7.tar.gz

我们在当前目录输入

tar -zvxf  php-7.3.7.tar.gz

cd php-7.3.7

编译php

./configure  --prefix=/usr/local/php7.3.7 \
--with-config-file-path=/usr/local/php7.3.7/etc \
--with-openssl \
--with-curl \
--with-mysql \
--with-pdo-mysql \
--with-mhash \
--with-xmlrpc \
--with-zlib \
--with-gd \
--with-jpeg-dir \
--with-png-dir \
--with-freetype-dir \
--enable-fileinfo \
 --enable-bcmath \
--enable-mbstring \
--enable-sockets \
--enable-xml \
--enable-fpm \
--enable-force-cgi-redirect \
--enable-zip \
--enable-soap \
--enable-ftp \
--without-pear

enable-bcmath php精度计算扩展

enable-fileinfo 文件操作

安装

make && make  install

最后显示安装成功

Build complete.
Don't forget to run 'make test'.

修改配置

复制php-fpm.conf 和php.ini配置文件

cp /usr/local/src/php-7.3.7/php.ini-production /usr/local/php/etc/php.ini
cp /usr/local/php7.3.7/etc/php-fpm.conf.default /usr/local/php7.3.7/etc/php-fpm.conf

1.然后 php.ini 修改

extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/"

2.配置php-fpm.conf

vim /usr/local/php/etc/php-fpm.conf

php-fpm.pid 目录必须指向：/usr/local/php/var/run/php-fpm.pid

如果服务器上安装多个php版本需要修改端口

cp /usr/local/php7.3.7/etc/php-fpm.d/www.conf.default /usr/local/php7.3.7/etc/php-fpm.d/www.conf

修改 www.conf 文件中

listen = 127.0.0.1:9000

改为9001

3.配置环境变量

vi /etc/profile

在末尾追加

PATH=$PATH:/usr/local/php7/bin
export PATH

执行命令使得改动立即生效

source /etc/profile

php添加到liunx服务

1..拷贝php-fpm脚本至/etc/init.d目录

cp /usr/local/src/php-7.3.7/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm7.3.7

3.设置权限并启动php-fpm：

chmod +x /etc/init.d/php-fpm7.3.7

/etc/init.d/php-fpm7.3.7 start

chkconfig --add php-fpm7.3.7

最后，给出php-fpm以服务的方式启动、停止和重启：

service php-fpm7.3.7 start

service php-fpm7.3.7 stop

service php-fpm7.3.7 reload

PHP配置Configure报错：Please reinstall the libzip distribution
发生情景：
php执行配置命令configure时，报如下错误：

checking for libzip... not found
configure: error: Please reinstall the libzip distribution

错误含义：
没有找到libzip
请重新安装libzip的dev包。
尝试解决：
（1）移除旧的libzip：

yum remove libzip

（2）安装新版本：

curl -O //libzip.org/download/libzip-1.5.1.tar.gz
tar -zxvf libzip-1.5.1.tar.gz
cd libzip-1.5.1
mkdir build
cd build
cmake ..
make && make install

注意：如果提示cmake版本过低，需新版本，则需要重新安装cmake。

liunx 安装cmake或升级cmake
