PHP的安裝雖然有時候很簡單,可是如果應用一多,我們安裝起來就很頭痛了!常見的就是PHP外掛程式的安裝問題最多了!

?????? 其實不管是你是Apache類的應用還是Nginx類的.PHP的安裝都不是很簡單,雖然網上很多configure,但是那不一定是適合你的,因為很多都直接關係著你的系統及系統版本和核心.那下面就進入正題

??? 首先來一個最常見的就是configure: error: libjpeg.(a|so) not found

?? 很多人都納悶兒了,我都安裝了的,為什麼就找不到呢?找不到其實就應試想到它的搜尋位置裡面是沒有的,要不然才不會說not found

??? 原因是我們大部分一些軟體只要rpm -qa | grep ***

???? 這時下面就有兩個重複的的軟體

[[email protected]_Server php-5.2.13]# rpm -qa | grep jpeg
libjpeg-6b-33
libjpeg-6b-33
libjpeg-devel-6b-33

32位和64位的都裝了。你可以強制移除兩個包，再重裝64位的包。rpm --allmatches --nodeps這種方法真是損系統又損你.有時候強制執行的東西也會隨便把lib中的一些包給強制刪了..所以我認為不建議這麼做,重複就讓它重複吧,沒關係的!

??? 要解決問題就是它沒找到,我安裝了的,那我得去找找看它到底是放那裡去了

[[email protected]_Server php-5.2.13]# updatedb
[[email protected]_Server php-5.2.13]# locate libjpeg.so
/usr/lib64/libjpeg.so.62
/usr/lib64/libjpeg.so.62.0.0
/usr/lib64/libjpeg.so
/usr/lib/libjpeg.so
[[email protected]_Server php-5.2.13]# locate libjpeg.a
/usr/lib64/libjpeg.a
/data0/software/jpeg-6b/libjpeg.a
[[email protected]_Server php-5.2.13]#

我們在編譯的時候經常看到一個庫的檔案,一般就是以*.a,*.so等名字的,嘗試的搜尋搜尋,不行就模糊搜尋!

通過上面的搜尋其實就知道一些原因了,configure一般的搜尋編譯路徑為/usr/lib/下,因為php預設就在/usr/lib/下找相關庫檔案,而x64機器上是在:/usr/lib64.這時你就可以直接把需要的庫檔案從/usr/lib64中拷貝到/usr/lib/中去就可以了.

那麼記得要在configure前執行如下的命令:

cp -frp /usr/lib64/libjpeg.* /usr/lib/

usr/bin/install: cannot create regular file `/usr/local/man/man1/cjpeg.1': No such file or directory
make: *** [install] Error 1
提示找不到目錄。既然電腦找不到，咱們人腦可以找嘛，自己先建立先
mkdir /usr/local/man
mkdir /usr/local/man1??? 建立完了再來
make install??? (沒報錯就成功)

configure: error: libjpng.(a|so) not found

其實也是和剛才的一樣.

cp -frp /usr/lib64/libpng* /usr/lib/

configure: error: Cannot find ldap libraries in /usr/lib.

cp -frp /usr/lib64/libldap* /usr/lib/

類似錯誤很多,方法也很多,我們得靈活應變,具體問題具體分析!

另外附一些常見的configure錯誤清單供參考:

configure: error: No curses/termcap library found
網上有的說法是：
--with-named-curses-libs=/usr/lib/libncursesw.so.5
其實是不對的，雖然能解決configure的錯誤，但是make的時候會提示錯誤，正確的做法應該是
yum -y install ncurses-devel
debian: apt-get install libncurses5-dev

configure: error: xml2-config not found
yum -y install libxml2-devel
debian:apt-get install libxml2-dev
