Centos 8 下的 PHP7/Nginx/Memcached/Redis 安装步骤。如果是Centos 7 请访问 Centos 7 x86_64 Nginx + PHP 安装步骤 ，本篇教程没有去配置 php.ini，我觉得这个配置根据个人需求自己配置即可。
一、获取相关开源程序
1、安装环境所需的程序库
yum -y update
yum -y remove mariadb*
yum install -y patch make cmake gcc gcc-c++ bison flex file libtool libtool-libs autoconf libaio libcap glibc glib2 kernel-devel glibc-devel glib2-devel curl unzip epel-release
yum install -y diffutils ncurses ncurses-devel libjpeg libpng freetype libxml2 zlib bzip2 libidn gettext libxslt libedit libtidy gd libyaml libxml2-devel openssl-devel bzip2-devel curl-devel libjpeg-devel libpng-devel freetype-devel cyrus-sasl-devel gmp-devel libtidy-devel libxslt-devel readline-devel zlib-devel gettext-devel gd-devel mhash mhash-devel libmemcached systemd systemd-devel
yum -y install libmcrypt libmcrypt-devel
2、准备环境变量
echo -e "/lib64
/usr/lib64
/usr/local/lib64
/lib
/usr/lib
/usr/local/lib
`cat /etc/ld.so.conf`" > /etc/ld.so.conf
/sbin/ldconfig
3、编译安装Centos 无法通过YUM安装的包
cd /usr/local/src
curl -fSL http://soft.laua.cn/libiconv/libiconv-1.15.tar.gz -o libiconv-1.15.tar.gz
tar zxf libiconv-1.15.tar.gz && rm -f libiconv-1.15.tar.gz
cd libiconv-1.15/
./configure --prefix=/usr/local --libdir=/usr/local/lib64 --enable-static
make -j "$(nproc)" && make install
cd ../
rm -rf /usr/local/src/libiconv-1.15
curl -fSL http://soft.laua.cn/icu/icu4c-65_1-src.tgz -o icu4c-65_1-src.tgz
tar zxf icu4c-65_1-src.tgz && rm -f icu4c-65_1-src.tgz
cd icu/source/
./configure --prefix=/usr/local --libdir=/usr/local/lib64 --enable-static
make -j "$(nproc)" && make install
cd ../../
rm -rf /usr/local/src/icu
curl -fSL http://soft.laua.cn/libzip/libzip-1.6.0.tar.gz -o libzip-1.6.0.tar.gz
tar zxf libzip-1.6.0.tar.gz && rm -f libzip-1.6.0.tar.gz
cd libzip-1.6.0
mkdir build && cd build && cmake3 .. && make && make install
cd ../../
rm -rf /usr/local/src/libzip-1.6.0
二、安装PHP 7（FastCGI模式）
1、编译安装PHP（FastCGI模式）
cd /usr/local/src

cd php-7.4.2/
/sbin/ldconfig

--with-gmp --with-tidy --with-pcre-dir --with-readline --with-fpm-systemd --with-zlib-dir --with-libdir=lib64
make -j "$(nproc)" ZEND_EXTRA_LIBS='-liconv'
make install
cp php.ini-production /usr/local/etc/php.ini
cp /usr/local/etc/php-fpm.conf.default /usr/local/etc/php-fpm.conf

mkdir -p /var/lib/nginx
mkdir -p /usr/local/etc/nginx/sites
cd ../
rm -rf /usr/local/src/nginx-1.17.8
四、收尾
1、优化内核
#for aliyun
cat >>/etc/security/limits.conf<<eof
* soft nproc 65535
* hard nproc 65535
eof
#other
cat >>/etc/security/limits.conf<<eof
* soft nproc 65535
* hard nproc 65535
* soft nofile 65535
* hard nofile 65535
eof
echo "fs.file-max=65535" >> /etc/sysctl.conf
3、设置开机启动
systemctl enable nginx.service
systemctl enable php-fpm.service
