rpm包安裝問題2:安裝ncurses-devel

rpm包安裝問題3:error while loading shared libraries
[root@localhost ~]# lftp root@192.168.1.18:22 lftp: error while loading shared libraries: libreadline.so.5: cannot open shared object file: No such file or directory tmux: error while loading shared libraries: libevent-1.4.so.2: cannot open shared object file: No such file or directory
原因一般有兩個, 一個是操作系統(tǒng)里確實(shí)沒有包含該共享庫(lib*.so.*文件)或者共享庫版本不對, 遇到這種情況那就去網(wǎng)上下載并安裝上即可.
另外一個原因就是已經(jīng)安裝了該共享庫, 但執(zhí)行需要調(diào)用該共享庫的程序的時候, 程序按照默認(rèn)共享庫路徑找不到該共享庫文件.
所以安裝共享庫后要注意共享庫路徑設(shè)置問題, 如下:
1) 如果共享庫文件安裝到了/lib或/usr/lib目錄下, 那么需執(zhí)行一下ldconfig命令
ldconfig命令的用途, 主要是在默認(rèn)搜尋目錄(/lib和/usr/lib)以及動態(tài)庫配置文件/etc/ld.so.conf內(nèi)所列的目錄下, 搜索出可共享的動態(tài)鏈接庫(格式如lib*.so*), 進(jìn)而創(chuàng)建出動態(tài)裝入程序(ld.so)所需的連接和緩存文件. 緩存文件默認(rèn)為/etc/ld.so.cache, 此文件保存已排好序的動態(tài)鏈接庫名字列表.
2) 如果共享庫文件安裝到了/usr/local/lib(很多開源的共享庫都會安裝到該目錄下)或其它"非/lib或/usr/lib"目錄下, 那么在執(zhí)行l(wèi)dconfig命令前, 還要把新共享庫目錄加入到共享庫配置文件/etc/ld.so.conf中, 如下:
# cat /etc/ld.so.conf include ld.so.conf.d/*.conf # echo "/usr/local/lib" >> /etc/ld.so.conf # ldconfig
3) 如果共享庫文件安裝到了其它"非/lib或/usr/lib" 目錄下, 但是又不想在/etc/ld.so.conf中加路徑(或者是沒有權(quán)限加路徑). 那可以export一個全局變量LD_LIBRARY_PATH, 然后運(yùn)行程序的時候就會去這個目錄中找共享庫.
LD_LIBRARY_PATH的意思是告訴loader在哪些目錄中可以找到共享庫. 可以設(shè)置多個搜索目錄, 這些目錄之間用冒號分隔開. 比如安裝了一個mysql到/usr/local/mysql目錄下, 其中有一大堆庫文件在/usr/local/mysql/lib下面, 則可以在.bashrc或.bash_profile或shell里加入以下語句即可:
export LD_LIBRARY_PATH=/usr/local/mysql/lib:$LD_LIBRARY_PATH
一般來講這只是一種臨時的解決方案, 在沒有權(quán)限或臨時需要的時候使用.
4)如果程序需要的庫文件比系統(tǒng)目前存在的村文件版本低,可以做一個鏈接
比如:
error while loading shared libraries: libncurses.so.4: cannot open shared object file: No such file or directory ls /usr/lib/libncu* /usr/lib/libncurses.a /usr/lib/libncurses.so.5 /usr/lib/libncurses.so /usr/lib/libncurses.so.5.3
可見雖然沒有l(wèi)ibncurses.so.4,但有l(wèi)ibncurses.so.5,是可以向下兼容的
建一個鏈接就好了
ln -s /usr/lib/libncurses.so.5.3 /usr/lib/libncurses.so.4

rpm格式: libjpeg-devel-6b-33.x86_64.rpm #rpm格式很好區(qū)分,
二進(jìn)制包: mysql-3.23.58-pc-linux-i686.tar.gz #二進(jìn)制格式的包名字很長,有版本號、適應(yīng)平臺、適應(yīng)的硬件類型等,格式:mysql-<版本>-<OS>-tar.gz
源碼包: php-5.2.14.tar.gz #而源碼格式僅僅就是一個版本號的tar包。#cj 安裝區(qū)別:解壓、./config、make、make install
source code 是程序員寫的碼,
binary code 是機(jī)器跑的碼。
source code 得經(jīng)過 compile 才能成為 binary code 。
RPM 有分兩種:binary rpm 跟 source rpm 。
前者是編好的 binary ,安裝就可用。
後者是還沒編好的 source ,需 rebuild 之後才能安裝
源代碼方式和二進(jìn)制包是軟件包的兩種形式。二進(jìn)制包里面包括了已經(jīng)經(jīng)過編譯,可以馬上運(yùn)行的程序。你只需要下載和解包(安裝)它們以后,就馬上可以使用。源代碼包里面包括了程序原始的程序代碼,需要在你的計算機(jī)上進(jìn)行編譯以后才可以產(chǎn)生可以運(yùn)行程序,所以從源代碼安裝的時間會比較長。
Linux下有個命令叫file,因為Linux并不是按照后綴名來判斷文件類型的。所以一般在不清楚文件到底是什么類型的時候,就用file這個命令去判斷。
file php-5.2.14.tar.gz
php-5.2.14.tar.gz: gzip compressed data, was "php-5.2.14.tar", from Unix, last modified: Wed Jul 21 22:32:34 2010, max compression
這個php-5.2.14.tar.gz 明顯是個gzip的壓縮包,這樣的文件一般都是用tar zxvf 命令去解包然后去配置編譯安裝的,通常情況把這種安裝方法叫做源碼編譯安裝。
file libjpeg-devel-6b-33.x86_64.rpm
libjpeg-devel-6b-33.x86_64.rpm: RPM v3 bin i386 libjpeg-devel-6b-33
這個libjpeg-devel-6b-33.x86_64.rpm 文件,就是個標(biāo)準(zhǔn)的redhat系列發(fā)行版本所用的RPM格式軟件包。一般在RHEL、CentOS、SUSE、OracleLinux下都可以安裝類似的RPM包。標(biāo)準(zhǔn)的安裝方法是rpm -ivh。
基本上紅帽系列Linux發(fā)行版本安裝軟件就這兩種方法了。還有經(jīng)常被提起的yum,其實(shí)就是由yum自動判斷rpm包的依賴,然后一次性把所有需要安裝的N個rpm統(tǒng)一下載安裝,其實(shí)原理和一個個的安裝rpm沒有什么本質(zhì)區(qū)別。
一般在官網(wǎng)上下載的源碼包都是以:tar.gz tar.bz2結(jié)尾的,經(jīng)過編譯的一般是以.rpm來結(jié)尾的,linux下的文件擴(kuò)展名沒有實(shí)際的意義,這樣做只是為了方便你去查看是什么類型的包然后采取什么樣的方式去安裝和配置,當(dāng)然有時候并不能從文件的擴(kuò)展名去查看什么類型的包,因為文件名可以隨意的去修改可以使用file這個命令去查看文件包的類型.
源碼的安裝一般由3個步驟組成:配置(configure)、編譯(make)、安裝(make install)。
Configure是一個可執(zhí)行腳本,它有很多選項,在待安裝的源碼路徑下使用命令./configure –help輸出詳細(xì)的選項列表。
其中--prefix選項是配置安裝的路徑,如果不配置該選項,安裝后可執(zhí)行文件默認(rèn)放在/usr /local/bin,庫文件默認(rèn)放在/usr/local/lib,配置文件默認(rèn)放在/usr/local/etc,其它的資源文件放在/usr /local/share,比較凌亂。
如果配置--prefix,如:
./configure --prefix=/usr/local/test
可以把所有資源文件放在/usr/local/test的路徑中,不會雜亂。
用了—prefix選項的另一個好處是卸載軟件或移植軟件。當(dāng)某個安裝的軟件不再需要時,只須簡單的刪除該安裝目錄,就可以把軟件卸載得干干凈凈;移植軟件只需拷貝整個目錄到另外一個機(jī)器即可(相同的操作系統(tǒng))。
當(dāng)然要卸載程序,也可以在原來的make目錄下用一次make uninstall,但前提是make文件指定過uninstall。

RPM安裝:
二進(jìn)制格式:
源程序-->編譯-->二進(jìn)制格式
有些特性是編譯選定的,如果編譯未選定此特性,將無法使用;
rpm包的版本會落后于源碼包,甚至落后很多;bind-9.8.7, bind-9.7.2
定制:手動編譯安裝
編譯環(huán)境,開發(fā)環(huán)境
開發(fā)庫,開發(fā)工具
Linux: C,
GNU: C
C,C++:
gcc: GNU C Complier, C
g++:
make: 項目管理工具,
makefile: 定義了make(gcc,g++)按何種次序去編譯這些源程序文件中的源程序
automake, --> makefile.in --> makefile
autoconf, --> configure
100個可選擇特性,
make install
編譯安裝的三步驟:
前提:準(zhǔn)備開發(fā)環(huán)境(編譯環(huán)境)
安裝"Development Tools"和"Development Libraries"
# tar
# cd
# ./configure
--help
--prefix=/path/to/somewhere
--sysconfdir=/PATH/TO/CONFFILE_PATH
功能:1、讓用戶選定編譯特性;2、檢查編譯環(huán)境;
# make
# make install
# tar xf tengine-1.4.2.tar.gz
# cd tegnine-1.4.2
# ./configure --prefix=/usr/local/tengine --conf-path=/etc/tengine/tengine.conf
# make
# make install
# /usr/local/tengine/sbin/nginx
1、修改PATH環(huán)境變量,以能夠識別此程序的二進(jìn)制文件路徑;
修改/etc/profile文件
在/etc/profile.d/目錄建立一個以.sh為名稱后綴的文件,在里面定義export PATH=$PATH:/path/to/somewhere
2、默認(rèn)情況下,系統(tǒng)搜索庫文件的路徑/lib, /usr/lib; 要增添額外搜尋路徑:
在/etc/ld.so.conf.d/中創(chuàng)建以.conf為后綴名的文件,而后把要增添的路徑直接寫至此文件中;
# ldconfig 通知系統(tǒng)重新搜尋庫文件
-v: 顯示重新搜尋庫的過程
3、頭文件:輸出給系統(tǒng)
默認(rèn):/usr/include
增添頭文件搜尋路徑,使用鏈接進(jìn)行:
/usr/local/tengine/include/ /usr/include/
兩種方式:
ln -s /usr/local/tengine/include/* /usr/include/ 或
ln -s /usr/local/tengine/include /usr/include/tengine
4、man文件路徑:安裝在--prefix指定的目錄下的man目錄;/usr/share/man
1、man -M /PATH/TO/MAN_DIR COMMAND
2、在/etc/man.config中添加一條MANPATH
netstat命令:
-r: 顯示路由表
-n: 以數(shù)字方式顯示
-t: 建立的tcp連接
-u: 顯示udp連接
-l: 顯示監(jiān)聽狀態(tài)的連接
-p: 顯示監(jiān)聽指定的套接字的進(jìn)程的進(jìn)程號及進(jìn)程名
