nginx unit的初探
安裝介紹:
https://www.oschina.net/p/nginx-unit
可以看到,unit還是很強大的,居然特麽都支持go 還有python
在/etc/yum.repos.d/unit.repo加入如下語句:
# cat /etc/yum.repos.d/unit.repo [unit] name=unit repo baseurl=https://packages.nginx.org/unit/centos/$releasever/$basearch/ gpgcheck=0 enabled=1 #
makecache yum源
# yum makecache
執行安裝 由於要測試unit-php,故安裝unit-php ,如果要測試python,可以安裝unit-python,如果要測試go,則安裝unit-go
# yum install unit unit-php
這裏有坑,安裝unit-php的時候,默認就安裝了5.3的
所以,如果你自己安裝了php7的,調用phpinfo的時候,會顯示php 5.3 ,原因在此,這個得需要源碼安裝,有點坑,過幾天再去踩踩
編輯配置文件
編輯配置文件,內容如下:
# cat /etc/unit/start.json { "listeners": { "*:8300": { "application": "blogs" } }, "applications": { "blogs": { "type": "php", "processes": 20, "root": "/usr/local/nginx/php", "index": "index.php" } } } #
啟動unit並且加載json文件
# /etc/init.d/unit start # /usr/local/bin/curl -X PUT -d @/etc/unit/start.json --unix-socket /var/run/control.unit.sock http://localhost{ "success": "Reconfiguration done." } 當出現success": "Reconfiguration done.則怎麽加載成功,可以用netstat查看端口是否已經開起來
註意,這裏有坑,如果要用curl的unix-socket參數,若curl包低於7.4需要進行升級
curl下載地址:https://curl.haxx.se/download/
例如,如下安裝方法:
# wget https://curl.haxx.se/download/curl-7.55.0.tar.gz ...解壓,進入目錄... # ./configure # make # make install如果在編譯的時候不指定安裝目錄,則會安裝到/usr/local/bin下面 查看版本
# /usr/local/bin/curl --version curl 7.55.0 (x86_64-pc-linux-gnu) libcurl/7.55.0 OpenSSL/1.0.1e zlib/1.2.3 Release-Date: 2017-08-09 Protocols: dict file ftp ftps gopher http https imap imaps pop3 pop3s rtsp smb smbs smtp smtps telnet tftp Features: IPv6 Largefile NTLM NTLM_WB SSL libz UnixSockets HTTPS-proxy #
查看加載的配置
# /usr/local/bin/curl --unix-socket /var/run/control.unit.sock http://localhost { "listeners": { "*:8300": { "application": "blogs" } }, "applications": { "blogs": { "type": "php", "processes": 20, "root": "/usr/local/nginx/php", "index": "index.php" } } } #
這時候,通過netstat可以看到8300端口已經打開了,
# cat /usr/local/nginx/php/index.php <?php phpinfo(); ?> #
通過8300訪問,就可以看看到phpinfo的界面了,但是前提是,root下,必須有index.php喲
重新加載配置文件
重新編寫配置文件
# cat /etc/unit/start.json { "listeners": { "*:8300": { "application": "blogs" } }, "applications": { "blogs": { "type": "php", "processes": 20, "root": "/usr/local/nginx/php", "index": "index.php", "user": "php", "group": "php", "options": { "file": "/usr/local/php7/lib/php.ini" } } } } #
重新加載配置文件
# /usr/local/bin/curl -X PUT -d @/etc/unit/start.json --unix-socket /var/run/control.unit.sock http://localhost { "success": "Reconfiguration done." }
再次查看配置文件
# /usr/local/bin/curl --unix-socket /var/run/control.unit.sock http://localhost { "listeners": { "*:8300": { "application": "blogs" } }, "applications": { "blogs": { "type": "php", "processes": 20, "root": "/usr/local/nginx/php", "index": "index.php", "user": "php", "group": "php", "options": { "file": "/usr/local/php7/lib/php.ini" } } } } #
這時候,可以通過頁面,訪問如下信息:
Nginx proxy_pass設置
只需要在location中添加如下幾項即可
proxy_pass http://127.0.0.1:8300; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
檢查語法,重啟nginx
# /usr/local/nginx/sbin/nginx -t nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful # /usr/local/nginx/sbin/nginx -s reload #
通過Nginx訪問界面如下:
可以看到,Server API 是unit
總結:
0.參考網址:http://unit.nginx.org/
1.unit 目前用的還很少,主流依然是php-fpm
2.如果能夠采用源碼編譯unit的話,當然是最好的
3.curl版本問題
4.編寫的json文件格式一定要正確,可以用在線工具檢測json是否正確(http://www.bejson.com/)
興趣才是最好的老師,加油吧。。。這玩意快搞了我加起來兩天時間了,
