【Raspberry Pi】CentOS7 に Zabbix をソースからインストールしてみる

ラズベリーパイで Zabbix を構築しようと思ったんですが、CentOS7 用のパッケージがなかったんですよね…
なんで、ソースからインストールしなきゃ、ってことで備忘録です。
ついでに Nginx と php-fpm もソースから最新版を導入してみます。

nginx

## 依存パッケージの導入
yum groupinstall "Development tools"
yum install libxml2-devel systemd-devel libpng-devel pcre-devel openssl openssl-devel wget

## nginxシステムユーザ作成
groupadd -g 500 nginx
useradd -g nginx -u 500 -s /sbin/nologin -M nginx

## ソースの取得＆ビルド
cd /usr/local/src/
wget http://nginx.org/download/nginx-1.19.2.tar.gz
tar xf nginx-1.19.2.tar.gz
cd nginx-1.19.2
./configure --conf-path=/etc/nginx/nginx.conf --user=nginx --group=nginx --with-http_ssl_module
make
make install

## 起動ファイル作成
vi /usr/lib/systemd/system/nginx.service
===============================================================
[Unit]
Description=nginx - high performance web server

PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStart=/usr/local/nginx/sbin/nginx -c /etc/nginx/nginx.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s TERM $MAINPID

[Install]
WantedBy=multi-user.target
