nginx php Primary script unknown

2014年3月10日 沒有評論

在centos6.4 x86_64上成功編譯安裝nginx 1.4、php 5.4后,成功啟動nginx和php-fpm后,訪問php提示錯誤,同時在錯誤日志中看到:

Primary script unknown ...

其中nginx配置片段如下:

location ~ \.php$ {
    root           /rootToWebFolderPath;
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  /rootToWebFolderPath/$fastcgi_script_name;
    include        fastcgi_params;
}

上述配置是正常工作在nginx 1.2、php 5.3下。所以懷疑是其他地方配置有誤,一番折騰,問題依舊,再次網上搜索,看到其中一篇文章中提到 fastcgi_param 配置不是使用覺得路徑,而是采用了變量($document_root)的方式。嘗試修改配置為:

location ~ \.php$ {
    root           /rootToWebFolderPath;
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include        fastcgi_params;
}

此時nginx、php正常工作了。注意:上述兩處配置中的 fastcgi_param 區別

aws ec2 硬盤 resize2fs

2014年3月10日 沒有評論

在申請aws ec2時,按照向導,在選擇存儲的時候默認硬盤大小是 8 G,這時候可以根據自己的需要輸入一個合適的數字,例如100。完成向導并啟動ec2 instance 后登陸機器。使用命令:

df -hT

發現硬盤的大小不是自己的設定的值,而還是 8 G,使用fdisk、mkfs來分區和格式化后,還是無法增大其空間。反復折騰多次,包括重啟機器,問題依舊,后來發現其實很簡單,只需要使用一條命令resize2fs就可以搞定。

resize2fs /dev/xvde

注意:“/dev/xvde” 根據自己的實際情況可能會不一樣。使用fdisk或df命令都可以獲知具體的設備號。 如果執行上述命令收到 The filesystem is already 2096896 blocks long. Nothing to do! 的錯誤,那么需要先做如下操作:

<<1>> Look at the filesystem, it is 6G
<<2>> Look at the disk and the partition, the disk is 21.5 GB but the partition is 6 GB (6291456 blocks)
<<3>> Start fdisk for that disk (xvda, so not the partition xvda1)
<<4>> Switch to sector display.
<<5>> Print the partition(s), and remember the start sector (2048 in the example).
<<6>> Delete the partition.
<<7>> Create a new partition.
<<8>> Make it primary.
<<9>> First partition.
<<10>> Enter the old start sector, do NOT make any typo here!!! (2048 in the example) 
<<11>> Hit enter to accept the default (this is the remainder of the disk)
<<12>> Print the changes and make sure the start sector is ok, if not restart at <<6>>
<<13>> Make the partition bootable. do NOT forget this!!!
<<14>> Enter your partition number (1 in the example)
<<15>> Write the partition info back, this will end the fdisk session.
<<16>> Reboot the server, and wait for it to come up (this may take longer than usual).
<<17>> Verify the filesystem size.
<<18>> If the filesystem is not around 20Gb as expected, you can use this command.

centos 64位編譯php出現Cannot find OpenSSL’s libraries

2014年3月10日 沒有評論

在一臺Centos6.4 64位編譯安裝php時候,出現Cannot find OpenSSL’s libraries,前提是已經確認通過yum 安裝過OpenSSL庫,在網上搜索,基本上得到的結果是安裝OpenSSL庫,對我的問題無濟于事。最后在一個論壇發現,因為是64位系統,OpenSSL庫安裝在/usr/lib64/,但在安裝php時,它還是去/usr/lib/ 下查找該庫,故報上述錯誤。清楚了問題所在,解決辦法就是做一個軟鏈接如下:

ln -s /usr/lib64/libssl.so /usr/lib/

Nginx could not build the server_names_hash 錯誤

2014年3月10日 沒有評論

在給nginx 配置了一個超長的域名后,通過 /usr/local/nginx/sbin/ngnix -t 檢查配置文件時出現一下錯誤:

could not build the server_names_hash, you should increase server_names_hash_bucket_size: 32

解決辦法是在nginx的配置文件的http段中增加如下配置:

server_names_hash_bucket_size 64;

如果已經存在,需要加大后面的數值,注意:該數值是32的倍數為宜。

具體信息可以參看nginx官網:http://nginx.org/cn/docs/http/server_names.html
