安裝postgreSQL出現configure:error:readline library not found解決方法

要安裝 readline , readline-dev 開發包，要么使用 --without-readline 選項關閉 readline 功能。

#yum install readline;

#yum install readline-dev;

readline 也就是命令行編輯，關閉的話，你直接用psql 就不能編輯命令行，如果輸錯指令，不能回滾命令歷史記錄，只能手工重新輸入。

在安裝postgreSQL的過程中遇到一個問題，在執行 configure

過程中報以下錯誤,configure: error: readline library not found ,可是我在系統中安裝
readline 包了，

1 環境信息

2 根據提示，測試了下 configre命令，果然報這個錯

If you have readline already installed, see config.log for details on the
failure.  It is possible the compiler isnt looking in the proper directory.
Use --without-readline to disable readline support.

     根據提示，應該是沒有安裝 readline包。

3 檢查系統是否安裝 readline 包
[root@HK81-107 postgresql-9.0.0]# rpm -qa | grep readline
readline-5.1-3.el5

   說明系統已經安裝了 readline包。

4 通過 yum 搜索相關的 readline 包
[root@HK81-107 postgresql-9.0.0]# yum search readline
lftp.i386 : A sophisticated file transfer program
lftp.i386 : A sophisticated file transfer program
php-readline.i386 : Standard PHP module provides readline library support
lftp.i386 : A sophisticated file transfer program
readline.i386 : A library for editing typed command lines.
compat-readline43.i386 : The readline 4.3 library for compatibility with older software.
readline-devel.i386 : Files needed to develop programs which use the readline library.
readline.i386 : A library for editing typed command lines.

 根據提示，有一個包引起了注意 "readline-devel", 猜想可能與這個包有關。
 
5 安裝 readline-devel 包
[root@HK81-107 postgresql-9.0.0]# yum -y install -y readline-devel

6 再次執行 configure 成功。

7 還有一種解決方法：在configure 加上參數 --without-readline ，不過這樣就不可以在命令行里面輸入了，所以不建議這樣。。。

8 configure 成功之后接着就是make了

9 make之后就是make install之后安裝成功的話就會出現如下圖所示的界面

 10.修改postgreSQL安裝目錄的權限，默認的安裝目錄在/usr/local/pgSQL下

修改權限命令為chmod -R 777 /usr/local/pgSQL

運行之后pgSQL目錄下面的所有文件都會有XWR(X：可執行，W：可寫，R：可讀)權限。命令中的-R參數說明是 遞歸的把文件夾pgSQL目錄及其目錄下的所有文件都修改為相應的權限，777就是代表加上對本用戶，本用戶組的其他用戶和不是這個組的用戶增加XWR權 限。

 

11.

到此，PostgreSQL的安裝完成了，接下來可以試着用用這個開源數據庫啦…

1)：首先是初始化數據庫。進入剛剛安裝PG的文件夾/home/pg/postgr(這是我安裝pg的目錄，默認的安裝目錄是在/usr/local/pgSQL下)，輸入./bin/initdb –D ../data. 這里的命令格式還需要查明白，特別是-D等參數的意義。這樣會在postgr下面產生一個data文件夾。

2)：啟動數據庫服務器。./bin/postmaster –D ./data&. 其中&的意義需要弄明白，差這一個符號就會導致一定的問題，貌似啟動數據庫服務器還可以使用另外的命令：/bin/postgres -D ./data 或者是 ./bin/pg_ctl -D ./data -l logfile start。這些命令的區別可以自己查查手冊或者咨詢一下助教。

 

 

3)：在另外一個命令行下面，創建一個本地數據庫。./bin/createdb testdb，其中testdb是數據庫名。在data目錄下會產生一個文件夾

 

 

4)：鏈接數據庫服務器。./bin/psql testdb. 此時，輸入help可以獲得幫助。見下圖

 

 

 

5)：訪問數據庫。這里就是輸入sql命令了，以后調試的入口就是這里吧。結束后按\q退出。

 

6)：最后是關閉數據庫服務器。./bin/pg_ctl stop –D ./data.

12.That's all！
