centos8升级php70到php7.4

一,下载php7.4
1,官方网站:

https://www.php.net/
2,下载
wget https://www.php.net/distributions/php-7.4.2.tar.gz

二,查看本地的centos的版本
[root@localhost lib]# cat /etc/redhat-release
CentOS Linux release 8.1.1911 (Core)
说明：在linux上以编译方式安装软件时，多数人都习惯把软件安装到 /usr/local目录下

三,解压和配置
tar -zxvf php-7.4.2.tar.gz
cd php-7.4.2/
./configure ‘–prefix=/usr/local/php74’ ‘–with-config-file-path=/usr/local/php74/etc’ ‘–enable-mysqlnd’ ‘–with-mysqli=mysqlnd’ ‘–with-pdo-mysql=mysqlnd’ ‘–with-mysql-sock=/tmp/mysql.sock’ ‘–with-freetype’ ‘–enable-gd’ ‘–with-jpeg’ ‘–with-zlib’ ‘–with-expat’ ‘–enable-xml’ ‘–enable-bcmath’ ‘–enable-shmop’ ‘–enable-sysvsem’ ‘–enable-inline-optimization’ ‘–enable-mbregex’ ‘–enable-mbstring’ ‘–enable-ftp’ ‘–with-openssl’ ‘–enable-sockets’ ‘–with-xmlrpc’ ‘–with-zip’ ‘–enable-soap’ ‘–without-pear’ ‘–with-gettext’ ‘–enable-session’ ‘–with-iconv’ ‘–with-mhash’ ‘–with-curl’ ‘–enable-intl’ ‘–enable-pcntl’ ‘–enable-fpm’ ‘–enable-opcache’ ‘–enable-fileinfo’
说明：上面的configure命令的参数是php-7.4.2可用的参数，
一些旧的不可用的参数会在configure时给出提示，
大家不要使用已经废弃的参数，避免安装完成后不能正常使用
安装依赖：
yum install libsqlite3x-devel -y
yum install libzip-devel
wget https://github.com/kkos/oniguruma/archive/v6.9.4.tar.gz -O oniguruma-6.9.4.tar.gz
tar -zxf oniguruma-6.9.4.tar.gz
cd oniguruma-6.9.4
yum install automake -y
yum install libtool -y
./autogen.sh && ./configure --prefix=/usr
make && make install

cd php-7.4.2/
make -j8 && make install
