如何在 Debian 9 下安装 LEMP 和 WHMCS 7.5

WHMCS 7.5 发布了，它开始支持 PHP 7.2，这里就写个简单的教程记录一下安装方式。

1、准备工作

首先，我们需要按照 在Debian 9 / Debian 8 下使用源安装方式安装 LEMP 一文，安装好 LEMP 环境，可以选一些需要用到的 PHP 7.2 软件包：

apt-get install php7.2-fpm php7.2-mysql php7.2-curl php7.2-gd php7.2-mbstring php7.2-xml php7.2-xmlrpc php7.2-zip php7.2-json php7.2-imap php7.2-opcache -y

2、安装 ionCube Loader 10

WHMCS 7.5 开始，已不支持老版本 ionCube Loader，所以我们需要从官网上下载最新的版本并进入解压后的 ioncube 目录

wget http://downloads.ioncube.com/loader_downloads/ioncube_loaders_lin_x86-64.zip
unzip ioncube_loaders_lin_x86-64.zip
cd ioncube

按照默认编译 PHP 7.2 的 PHP Extension 我们可以找到 PHP 7.2 扩展的目录在 /usr/lib/php/20170718/

对应的话，PHP 7.0 在 /usr/lib/php/20151012/，PHP 7.1 在 /usr/lib/php/20160303/

然后把 ioncube 目录里的 ioncube_loader_lin_7.2.so 给复制过去

cp -r ioncube_loader_lin_7.2.so /usr/lib/php/20170718/

对应 PHP 7.1 就是

cp -r ioncube_loader_lin_7.1.so /usr/lib/php/20160303/

对应 PHP 7.0 就是

cp -r ioncube_loader_lin_7.0.so /usr/lib/php/20151012/

然后增加一个 FPM 的模块配置文件

cat >> /etc/php/7.2/mods-available/ioncube.ini << EOF
zend_extension = ioncube_loader_lin_7.2.so

然后给 PHP-FPM 和 PHP-Cli 都增加 ioncube 模块

ln -s /etc/php/7.2/mods-available/ioncube.ini /etc/php/7.2/fpm/conf.d/01-ioncube.ini
ln -s /etc/php/7.2/mods-available/ioncube.ini /etc/php/7.2/cli/conf.d/01-ioncube.ini

然后重启 PHP-FPM

systemctl restart php7.2-fpm

我们来检查一下是否生效

root@debian ~ # php -v
PHP 7.2.3-1+0~20180306120016.19+stretch~1.gbp81bf3b (cli) (built: Mar 6 2018 12:00:19) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
with the ionCube PHP Loader (enabled) + Intrusion Protection from ioncube24.com (unconfigured) v10.2.0, Copyright (c) 2002-2018, by ionCube Ltd.

看到 with the ionCube PHP Loader (enabled) 即可

PS：对应的 PHP 7.1 和 PHP 7.0 用户请自行修改目录，不再重复

3、修改 MySQL 配置

按照官方说明，WHMCS 7 开始不支持 SQL strict 模式

WHMCS requires MySQL strict mode to be turned off in order for it to function.

所以我们需要关闭 Percona Server 里默认开启的 SQL strict 模式

直接修改 /etc/mysql/percona-server.conf.d/mysqld.cnf 文件，把 sql_mode 改成 sql_mode=NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION 即可

最后这文件看上去就像这样子

[mysqld]
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
explicit_defaults_for_timestamp

# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address = 127.0.0.1

log-error = /var/log/mysql/error.log

# Recommended in standard MySQL setup
sql_mode=NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

---------------

[mysqld]
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
explicit_defaults_for_timestamp

# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address = 127.0.0.1

log-error = /var/log/mysql/error.log

# Recommended in standard MySQL setup
sql_mode=NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

重启 MySQL

systemctl restart mysql

最后配置 Nginx 和安装 WHMCS 就不再多重复了
