PHP的安装虽然有时候很简单,可是如果应用一多,我们安装起来就很头痛了!常见的就是PHP插件的安装问题最多了!
?????? 其实不管是你是Apache类的应用还是Nginx类的.PHP的安装都不是很简单,虽然网上很多configure,但是那不一定是适合你的,因为很多都直接关系着你的系统及系统版本和内核.那下面就进入正题
??? 首先来一个最常见的就是configure: error: libjpeg.(a|so) not found
?? 很多人都纳闷儿了,我都安装了的,为什么就找不到呢?找不到其实就应试想到它的搜索位置里面是没有的,要不然才不会说not found
??? 原因是我们大部分一些软件只要rpm -qa | grep ***
???? 这时下面就有两个重复的的软件
[[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位的都装了。你可以强制删除两个包，再重装64位的包。rpm --allmatches --nodeps这种方法真是损系统又损你.有时候强制执行的东西也会随便把lib中的一些包给强制删了..所以我认为不建议这么做,重复就让它重复吧,没关系的!
??? 要解决问题就是它没找到,我安装了的,那我得去找找看它到底是放那里去了
[[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]#
我们在编译的时候经常看到一个库的文件,一般就是以*.a,*.so等名字的,尝试的搜索搜索,不行就模糊搜索!
通过上面的搜索其实就知道一些原因了,configure一般的搜索编译路径为/usr/lib/下,因为php默认就在/usr/lib/下找相关库文件,而x64机器上是在:/usr/lib64.这时你就可以直接把需要的库文件从/usr/lib64中拷贝到/usr/lib/中去就可以了.
那么记得要在configure前执行如下的命令:
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
提示找不到目录。既然电脑找不到，咱们人脑可以找嘛，自己先创建先
mkdir /usr/local/man
mkdir /usr/local/man1??? 创建完了再来
make install??? (没报错就成功)
configure: error: libjpng.(a|so) not found
其实也是和刚才的一样.
cp -frp /usr/lib64/libpng* /usr/lib/
configure: error: Cannot find ldap libraries in /usr/lib.
cp -frp /usr/lib64/libldap* /usr/lib/
类似错误很多,方法也很多,我们得灵活应变,具体问题具体分析!
另外附一些常见的configure错误列表供参考:
configure: error: No curses/termcap library found
网上有的说法是：
--with-named-curses-libs=/usr/lib/libncursesw.so.5
其实是不对的，虽然能解决configure的错误，但是make的时候会提示错误，正确的做法应该是
yum -y install ncurses-devel
debian: apt-get install libncurses5-dev
configure: error: xml2-config not found
yum -y install libxml2-devel
