遇到的问题与解决方案

问题一:

./configure以下错误发生

Sorry, I cannot run apxs. Possiblereasons follow:
1. Perl is not installed

2. apxs was not found. Try to pass the path using--with-apxs2=/path/to/apxs

3. Apache was not built using --enable-so (the apxs usage page isdisplayed)

解决方法：指定正确的apxs路径

1.查找apxs路径

# whereis apxs

apxs:

说明系统没有安装apxs扩展工具

2.安装apxs

# yum install httpd-devel

3.查找apxs路径

# whereis apxs

apxs: /usr/sbin/apxs /usr/share/man/man8/apxs.8.gz

apxs安装成功

问题二：

安装apxs以下错误发生：

Package cyrus-sasl-plain needs cyrus-sasl-lib = 2.1.22-4, thisis not available.

解决方法：

# yum -y install cyrus*

之后再次安装apxs

问题三：

再次./configure以下错误发生

configure: error: xml2-config not found. Please check your libxml2installation.

解决方法：

安装libxml2

# yum install libxml2-devel

问题四：

hecking libxml2 install dir... no

checking for xml2-config path... /usr/bin/xml2-config

checking whether libxml build works... no

configure: error: build test failed. Pleasecheck the config.log for details.

解决方法：

# yum erase zlib-devel

# yum install zlib-devel

# yum install libxml2-devel
