新安裝的系統,軟件包更新,首先找一個速度不錯的Ubuntu源,這裏網上搜了一個。

安裝Nginx

apt-get install nginx |
安裝Mysql-server

apt-get install mysql-server |
安裝php,php-fpm,php常用模塊

就這樣,把Nginx,mysql,php都安裝好了,安裝好後都是啓動了的,手動啓動或者停止服務用下面的命令。

php5-fpm start #啓動php5-fpm service
php5-fpm restart #重啓php5-fpm service
php5-fpm reload #重加載php5-fpm service
php5-fpm stop #停止php5-fpm service
mysql start #啓動mysql service
mysql restart #重啓mysql service
mysql stop #停止mysql |
安裝好了,還需要做一些優化配置。

上面的是按照服務器8個cpu來配置的,也就是每個cpu開一個worker總共8個,並且指定每個worker的序號
php-fpm優化配置,主要是進出數的配置,找到以下幾個關鍵配置選項,在/etc/php5/fpm/poll.d/www.conf

pm
= dynamic #這裏可以設置爲dynamic/static,前者爲動態管理php-fpm進程,後者爲靜態 pm.max_children
200 #最大的子進程數量,這個參數只在pm=static模式下有效,dynamic模式得下面參控制 pm.start_servers
= 200 #啓動的時候開啓的進程數 pm.min_spare_servers
= 100 #空閒時候最少保留的進程數 pm.max_spare_servers
= 300 #最大進程數 |
上面假如選擇pm的方式爲static,那麼只有pm.max_children參數設置起作用,因爲使用靜態的模式管理進程,php-fpm管理器只會靜態的設置最大的進程數量爲max_children,而反過來,使用pm=dynamic,則pm.max_children不起作用了,會根據下面的三個參數聯合控制。這裏,pm.start_servers是要根據pm.min_spare_servers和pm.max_spare_servers兩個參數的設置計算來的,公式爲:pm.start_servers = pm.min_spare_servers
+ (pm.max_spare_servers – pm.min_spare_servers)/2。
另外,到底開啓多少進程數合適呢?以及選擇怎樣的模式更好呢?
假如服務器配置不錯,那就是用static模式,畢竟動態的管理php-fpm進程會有消耗服務器資源,以及數量上的話,一般一個php-fpm據說是消耗20-30MB的內存(我自己也沒考究過-_-!)。按照這樣算,1G內存的機器,大概開30個差不多了,8G的話,我多的時候是配置到了300個最大進程數量。
