Centos8安装php7.2

安装必要的依赖软件

如果已经安装了可能会进行升级，版本完全一致则不会进行任何操作。

yum -y install bzip2-devel curl-devel freetype-devel gcc libjpeg-devel libpng-devel libxslt-devel libxml2-devel openssl-devel pcre-devel pcre-devel zlib-devel

   1、下载php

下载地址：http://php.net/get/php-7.0.11.tar.gz/from/a/mirror

下载“php-7.0.11.tar.gz”后移动到linux服务器的任意目录下，只在编译时指定安装到的目录。

    2、解压安装包

tar -zxvf php-7.0.11.tar.gz
cd php-7.0.11

    3、配置安装变量

./configure --prefix=/usr/local/php --with-curl --with-freetype-dir --with-gd --with-gettext --with-iconv-dir --with-kerberos --with-libdir=lib64 --with-libxml-dir --with-mysqli --with-openssl --with-pcre-regex --with-pdo-mysql --with-pdo-sqlite --with-pear --with-png-dir --with-jpeg-dir --with-xmlrpc --with-xsl --with-zlib --with-bz2 --with-mhash --enable-fpm --enable-bcmath --enable-libxml --enable-inline-optimization --enable-gd-native-ttf --enable-mbregex --enable-mbstring --enable-opcache --enable-pcntl --enable-shmop --enable-soap --enable-sockets --enable-sysvsem --enable-sysvshm --enable-xml --enable-zip

“/usr/local/php”是安装路径，可以改成自己喜欢的安装路径。

    4、编译源码

# 在解压目录执行编译命令：make
cd php-7.0.11
make

编译会花费一些时间，耐心等待即可。编译完成的最后会提示你执行make test命令。就是对上一步 make 的检查，

要确保 make 是没有错误的，也就是这一步的 test、check要全部是 OK 的，error 为0。

    5、安装php

make install

    6、配置PHP

将PHP源码包（/usr/local/php-7.0.11）中的php.ini-development文件复制到/usr/local/php/下，更名为php.ini。

cp /usr/local/php-7.0.11/php.ini-development /usr/local/php/php.ini
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf

配置php.ini “cgi.fix_pathinfo=0”

启动php-fpm服务：

/usr/local/php/sbin/php-fpm

    7、配置nginx

编辑nginx配置文件/usr/local/nginx/conf/nginx.conf，主要修改nginx的server {}配置块中的内容，修改location块，追加index.php让nginx服务器默认支持index.php为首页：

然后配置.php请求被传送到后端的php-fpm模块，默认情况下php配置块是被注释的，此时去掉注释并修改为以下内容：

location ~* \.php$ {
        root           html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

这里面很多都是默认的，root是配置php程序放置的根目录，主要修改的就是fastcgi_param中的/scripts为$document_root

修改完这些保存并退出，然后重启nginx：/usr/local/nginx/sbin/nginx -s reload

接下来编辑一个测试的php程序，在nginx下的html目录下创建test.php文件，打印一下php配置：

<?php
    phpinfo();
?>

　　然后打开浏览器输入对应的地址进行访问，看到输出页面，说明nginx和php都配置成功了：

设置开机自启动

设置软连接
ln -sf /www/server/php/bin/php /usr/bin/php
ln -sf /www/server/php/bin/phpize /usr/bin/phpize
ln -sf /www/server/php/bin/pear /usr/bin/pear
ln -sf /www/server/php/bin/pecl /usr/bin/pecl
ln -sf /www/server/php/sbin/php-fpm /usr/bin/php-fpm

/etc/systemd/system/添加文件php-fpm.service

内容如下

# It's not recommended to modify this file in-place, because it
# will be overwritten during upgrades.  If you want to customize,
# the best way is to use the "systemctl edit" command.

查看当前状态
systemctl start php-fpm.service

设置开启其他

systemctl enable php-fpm.service

刷新配置文件

systemctl daemon-reload

systemctl list-unit-files|grep php-fpm

出现php-fpm.service enabled 表示成功开启
