CentOS 7安装php7.4

1、yum安装

#安装依赖
yum install epel-release

#启用PHP 7.4 Remi存储库并在CentOS 7上安装PHP 7.4#配置安装源
yum -yinstall https://rpms.remirepo.net/enterprise/remi-release-7.rpm
yum -yinstall yum-utils

#设置安装版本
yum-config-manager --enable remi-php74

#安装php及拓展包
yum install php php-cli php-fpm php-mysqlnd php-zip php-devel php-gd php-mcrypt php-mbstring php-curl php-xml php-pear php-bcmath php-json php-redis

#查看php版本
php -v#启动php
systemctl start php-fpm

#php配置文件vi /etc/php.ini

#修改php上传限制，默认为2M
upload_max_filesize = 500M

2、编译安装

1、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 zlib zlib-devel glibc glibc-devel glib2 glib2-devel ncurses curl gdbm-devel db4-devel libXpm-devel libX11-devel gd-devel gmp-devel expat-devel xmlrpc-c xmlrpc-c-devel libicu-devel libmcrypt-devel libmemcached-devel libsqlite3x-devel oniguruma-devel

2、安装编译工具

yum groupinstall 'Development Tools'

3、下载解压

wget http://mirrors.sohu.com/php/php-7.4.9.tar.gz
#此处目录为roottar-zxvf php-7.4.9.tar.gz
cd php-7.4.9
#编译

#makemake&makeinstall#设置环境变量vi /etc/profile

编译遇到以下问题解决办法

#configure: error: Package requirements (libxml-2.0 >= 2.7.6) were not met:#Package ‘libxml-2.0’, required by ‘virtual:world’, not found
yum install libxml2-devel -y#configure: error: Package requirements (krb5-gssapi krb5) were not met:#Package 'krb5-gssapi', required by 'virtual:world', not found#Package 'krb5', required by 'virtual:world', not found
yum install krb5-devel -y#configure: error: Package requirements (openssl >= 1.0.1) were not met:#Package 'openssl', required by 'virtual:world', not found
yum install openssl-devel -y#configure: error: Package requirements (sqlite3 > 3.7.4) were not met:#Package 'sqlite3', required by 'virtual:world', not found
yum install sqlite-devel -y#configure: error: Please reinstall the BZip2 distribution
yum -yinstall bzip2-devel

yum install libzip-devel -y

3、编译安装拓展包

#进入源代码中ext文件夹下需要编译的拓展的文件夹中，比如编译gd,则进入源代码ext文件夹下的gd#编译好后的php安装目录下的phpize,执行后生成configure文件
/usr/local/php74/bin/phpize

#进行配置
./configure --with-php-config=/usr/local/php74/bin/php-config

#编译make&makeinstall#make中可能报以下错误#PHP编译安装报错，make:*libtool: link: `ext/libxml/libxml.lo‘ is not a valid libtool object#把 php的源代码目录（你make过的）删掉， 再解压， 然后再 make 应该就 ok 了#编译安装完成后会显示一个目录
Installing shared extensions:     /usr/local/php74/lib/php/extensions/no-debug-non-zts-20190902/

#编辑php.ini,编译的php一般都是在其安装目录下有一个etc文件夹，里面有一个php.ini#此处为/usr/local/php74/etc/php.ini#将/usr/local/php74/lib/php/extensions/no-debug-non-zts-20190902/目录添加到php.ini，大概有一个extension_dir=xxx,在其下面添加一行，把编译好后的路径添加上extension_dir=/usr/local/php74/lib/php/extensions/no-debug-non-zts-20190902/

#再找到对应的模块启用#对应模块显示类似为为;extension=gd，去掉前面的分号保存，如果没有则手动添加extension=gd

#重新启动php
