CentOS 7 yum安装 PHP7.3 教程

参考： https://www.mf8.biz/centos-rhel-install-php7-3/

1、首先安装 EPEL 源：

yum install epel-release

安装 REMI 源：

yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm  

2、安装 Yum 源管理工具：

yum install yum-utils

3、安装 PHP7.3：

yum install -y php73-php-fpm php73-php-cli php73-php-bcmath php73-php-gd php73-php-json php73-php-mbstring php73-php-mcrypt php73-php-mysqlnd php73-php-opcache php73-php-pdo php73-php-pecl-crypto php73-php-pecl-mcrypt php73-php-pecl-geoip php73-php-recode php73-php-snmp php73-php-soap php73-php-xmll

安装完成后最好重启一下计算机，不然有可能无法启动php
设置开机启动、运行服务：

systemctl enable php73-php-fpmsystemctl start php73-php-fpm

设置 PHP
查找安装包：

[root@xxx etc]# rpm -qa | grep 'php'php73-php-cli-7.3.6-1.el7.remi.x86_64php73-php-mbstring-7.3.6-1.el7.remi.x86_64php73-php-pecl-mcrypt-1.0.2-1.el7.remi.x86_64php73-runtime-2.0-1.el7.remi.x86_64php73-php-pdo-7.3.6-1.el7.remi.x86_64php73-php-bcmath-7.3.6-1.el7.remi.x86_64php73-php-fpm-7.3.6-1.el7.remi.x86_64php73-php-mysqlnd-7.3.6-1.el7.remi.x86_64php73-php-snmp-7.3.6-1.el7.remi.x86_64php73-php-gd-7.3.6-1.el7.remi.x86_64php73-php-json-7.3.6-1.el7.remi.x86_64php73-php-soap-7.3.6-1.el7.remi.x86_64php73-php-recode-7.3.6-1.el7.remi.x86_64php73-php-pecl-crypto-0.3.1-5.el7.remi.x86_64php73-php-common-7.3.6-1.el7.remi.x86_64php73-php-opcache-7.3.6-1.el7.remi.x86_64php73-php-pecl-geoip-1.1.1-6.el7.remi.x86_64

找到：php73-php-fpm-7.3.6-1.el7.remi.x86_64安装位置

[root@xxx etc]# rpm -ql php73-php-fpm-7.3.6-1.el7.remi.x86_64/etc/logrotate.d/php73-php-fpm/etc/opt/remi/php73/php-fpm.conf/etc/opt/remi/php73/php-fpm.d/etc/opt/remi/php73/php-fpm.d/www.conf/etc/opt/remi/php73/sysconfig/php-fpm/etc/systemd/system/php73-php-fpm.service.d/opt/remi/php73/root/usr/sbin/php-fpm/opt/remi/php73/root/usr/share/doc/php73-php-fpm-7.3.6/opt/remi/php73/root/usr/share/doc/php73-php-fpm-7.3.6/php-fpm.conf.default/opt/remi/php73/root/usr/share/doc/php73-php-fpm-7.3.6/www.conf.default/opt/remi/php73/root/usr/share/fpm/opt/remi/php73/root/usr/share/fpm/status.html/opt/remi/php73/root/usr/share/licenses/php73-php-fpm-7.3.6/opt/remi/php73/root/usr/share/licenses/php73-php-fpm-7.3.6/fpm_LICENSE/opt/remi/php73/root/usr/share/man/man8/php-fpm.8.gz/usr/lib/systemd/system/php73-php-fpm.service/var/opt/remi/php73/lib/php/opcache/var/opt/remi/php73/lib/php/session/var/opt/remi/php73/lib/php/wsdlcache/var/opt/remi/php73/log/php-fpm/var/opt/remi/php73/run/php-fpm

查找php.ini位置：

[root@xxx etc]# find /etc/opt/remi/php73 -name php.ini/etc/opt/remi/php73/php.ini

编辑/etc/opt/remi/php73/php.ini替换换 ;cgi.fix_pathinfo=1 为 cgi.fix_pathinfo=0 快捷命令：

sed -i 's/;cgi.fix_pathinfo=1/cgi.fix_pathinfo=0/' /etc/opt/remi/php73/php.ini

重启php73-php-fpm

systemctl restart php73-php-fpm

更多操作：

systemctl restart php73-php-fpm #重启systemctl start php73-php-fpm #启动systemctl stop php73-php-fpm #关闭systemctl status php73-php-fpm #检查状态

查看 PHP
验证一下是否安装成功：
