CentOS8 install PHP7.3+Swoole4.4+MySql8.0+Redis5.0+Nginx

本文由简悦 SimpRead 转码，原文地址 http://doc.seagm.io/web/#/p/9271ba8a1ac976a05fd53c76b0855adc

yum update

先安装一下 git 和 nginx

yum install git nginx -y

安装 php: step 1

yum install epel-release

安装 php: step 2

yum install http://rpms.remirepo.net/enterprise/remi-release-8.rpm

安装 php: step 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
yum install -y php73-php-xml

查看安装的 PHP 版本

php73 -v

关于 php-fpm 的启停:

不是本次安装使用的重点，本次主要是使用 swoole 作服务器，不需要使用 php-fpm

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

安装 pecl，然后通过 pecl 来安装 swoole

wget http://pear.php.net/go-pear.phar
php73 go-pear.phar
yum install php73-php-pear

由于环境变量的原因，直接输入 pecl 命令找不到，这里直接输入完整路径

sudo /opt/remi/php73/root/usr/bin/pecl install swoole

下载太慢，等了很久最终下载失败，手动到网站上下载然后上传到服务器
https://pecl.php.net/package/swoole

本地上传服务器

在服务器上指定安装文件安装，提示需要安装 php73-php-devel，于是安装

yum install php73-php-devel

但是遇到问题：

Problem: cannot install the best candidate for the job
  - nothing provides libedit-devel(x86-64) needed by php-devel-7.3.10-1.el8.remi.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

解决方式：

dnf config-manager --set-enabled PowerTools

然后再安装 php73-php-devel，安装完后，再安装 swoole

sudo /opt/remi/php73/root/usr/bin/pecl install ./swoole-4.4.17.tgz

安装完后，提示将 swoole.so 配置到 php.ini 中

Build process completed successfully
Installing '/opt/remi/php73/root/usr/lib64/php/modules/swoole.so'
Installing '/opt/remi/php73/root/usr/include/php/ext/swoole/config.h'
install ok: channel://pecl.php.net/swoole-4.4.17
configuration option "php_ini" is not set to php.ini location
You should add "extension=swoole.so" to php.ini

注意：不能放到最前面，至少需要放到加载 mysql 之后。

通过 php73 --ini 可以查看 php 使用到的配置文件

/etc/opt/remi/php73/php.d/40-geoip.ini

注意配置文件名前的编号，php 是按这个顺序加载的。

进到配置文件目录，复制一个配置文件，编号为 50-swoole.ini

[root@iZm5eccrtb2rzofq0fcwcaZ tmp]# cd /etc/opt/remi/php73/php.d/
[root@iZm5eccrtb2rzofq0fcwcaZ php.d]# cp 40-geoip.ini 50-swoole.ini
[root@iZm5eccrtb2rzofq0fcwcaZ php.d]# vi 50-swoole.ini

50-swoole.ini 的内容

extension=swoole.so

现在可以通过 php73 -m 查看到 swoole 扩展已安装完成.

安装 MySQL: 参照 MySQL 官网文档
