CentOS下libiconv库如何手动安装和使用介绍

今天小编要为大家带来的是CentOS下libiconv库的安装和使用介绍!希望对大家会有帮助!有需要的朋友一起去看看吧

Linux下安装libiconv使php支持iconv函数

libiconv组件安装好了可以让我们php支持iconv函数了,这个函数的作用就是字符编码强制转换了,下面和111cn小编一起来看一个Linux中安装libiconv使php支持iconv函数的例子吧。 


问题:

线上运行的lamp服务器,php不支持iconv函数。

解决方法:

安装libiconv,重新编译apache,使php支持iconv函数,实现utf-8和gb2312编码的转换。

具体步骤:

1、下载libiconv

cd /usr/local/src

wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.15.tar.gz #下载

2、安装libiconv

cd /usr/local/src

tar zxvf libiconv-1.15.tar.gz #解压

cd libiconv-1.15 #进入安装目录

./configure –prefix=/usr/local/libiconv #配置

make #编译

make install #安装

3、重新编译php

查找系统之前的php编译参数

cd /usr/local/php/bin  #进入php安装目录

./php -i |more #查看php编译参数

如下:

‘–with-pdo_sqlite=shared’ ‘–enable-bcmath=shared’ ‘–enable-ftp=shared’ ‘–enable-mbstring=shared’ ‘–with-iconv=shared’ ‘–enable-sockets=shared’ ‘–enable-zip’ ‘–enable-soap=s

hared’ ‘–with-openssl’ ‘–with-zlib’ ‘–with-curl=shared’ ‘–with-gd=shared’ ‘–with-jpeg-dir’ ‘–with-png-dir’ ‘–with-freetype-dir’ ‘–with-mcrypt=shared’ ‘–with-mhash=shared’ ‘–with-mysql=/ho

me/server/mysql’ ‘–with-mysqli=/home/server/mysql/bin/mysql_config’ ‘–with-pdo-mysql=/home/server/mysql/bin/mysql_config’ ‘–without-pear’ ‘–with-libdir=lib64’

对参数进行修改:

如下

./configure –prefix=/usr/local/php –with-config-file-path=/usr/local/php/etc –with-apxs2=/usr/local/apache/bin/apxs –with-gettext=shared –with-sqlite=shared –with-pdo_sqlite=shared –enable-bcmath=shared –enable-ftp=shared –enable-mbstring=shared –with-iconv-dir=/usr/local/libiconv –enable-sockets=shared –enable-zip –enable-soap=shared –with-openssl –with-zlib –with-curl=shared –with-gd=shared –with-jpeg-dir –with-png-dir –with-freetype-dir –with-mcrypt=shared –with-mhash=shared –with-mysql=/home/server/mysql –with-mysqli=/home/server/mysql/bin/mysql_config –with-pdo-mysql=/home/server/mysql/bin/mysql_config –without-pear –with-libdir=lib64

备注:修改部分


取消原来的–with-iconv=shared

替换为:–with-iconv-dir=/usr/local/libiconv

取消参数两边的单引号

其它不变

cd /usr/local/src/php #进入php安装包目录(注意php版本要和之前一样)

./configure –prefix=/usr/local/php –with-config-file-path=/usr/local/php/etc –with-apxs2=/usr/local/apache/bin/apxs –with-gettext=shared –with-sqlite=shared –with-pdo_sqlite=shared –enable-bcmath=shared –enable-ftp=shared –enable-mbstring=shared –with-iconv-dir=/usr/local/libiconv –enable-sockets=shared –enable-zip –enable-soap=shared –with-openssl –with-zlib –with-curl=shared –with-gd=shared –with-jpeg-dir –with-png-dir –with-freetype-dir –with-mcrypt=shared –with-mhash=shared –with-mysql=/home/server/mysql –with-mysqli=/home/server/mysql/bin/mysql_config –with-pdo-mysql=/home/server/mysql/bin/mysql_config –without-pear –with-libdir=lib64 #配置

make #编译

make install #安装

4、重启apache使设置生效

service httpd restart #重启

故障解决!

Linux下libiconv库的安装和使用:

1.编译安装libiconv库

包的下载页面http://www.gnu.org/software/libiconv/

$ ./configure –prefix=/usr/local

$ make
