linux下面安装apache
?
1. 如果实用wget-install 安装，默认安装到/etc目录下面
2. apachectl 用法：sudo apachectl -f /home/work/httpd/httpd.conf -k start
首先切换到root权限，安装apache需要 apr,apr-util,zlib-dev
3. 加入sudo组，编辑/etc/sudoer
步骤:
1. 下载
wget http://labs.renren.com/apache-mirror//httpd/httpd-2.2.22.tar.gz
wget http://labs.renren.com/apache-mirror/apr/apr-1.4.6.tar.gz
wget http://labs.renren.com/apache-mirror/apr/apr-util-1.3.12.tar.gz
———————————————————
2. 解压
tar xvf httpd-2.2.19.tar.gz
tar xvf apr-1.4.5.tar.gz
tar xvf apr-util-1.3.12.tar.gz
———————————————————
3.安装
? a.安装apr
??? ./configure –prefix=/usr/local/apr
??? make
???
make install
? b.安装apr-util
???
./configure –prefix=/usr/local/apr-util –with-apr=/usr/local/apr
???
make
???
make install
? c.安装zlib-devel
???
apt-get install zlib1g-dev
? d.安装httpd
./configure –prefix=/atlas/dist/sys/httpd –enable-rewrite=static –with-mpm=worker –enable-so –enable-proxy –enable-proxy-http –enable-deflate –with-apr=/atlas/dist/sys/apr –with-apr-util=/atlas/dist/sys/apr-util –with-included-apr
??? make
???
make install
———————————————————
4.修改启动脚本权限
sudo chmod a+s apachectl
sudo chmod a+s httpd
?
———————————————————
问题记录：
1.明明安装了apr-util,还是提示错误：configure: error: APR version 1.2.0
注意要增加 –with-included-apr 参数。
2. 出现错误提示：checking whether to enable mod_deflate… configure: error: mod_deflate has been requested but can not be built due to prerequisite failures
zlib-devel 没装的原因:
ubunt: apt-get install zlib1g-dev
centos:? yum install zlib-devel.i686
3.出现错误：configure: error: C compiler cannot create executables
检查gcc版本，发现gcc版本是gcc-4.4,编译需要gcc-4.5,remove掉，重新安装,ok
apt-get remove gcc-4.4
apt-get install gcc-4.5
如果发现无法安装GCC，可以试试：sudo
?
apt-get
??
install
??
build-essential
4.非root无法启动：(13)Permission denied: make_sock: could not bind to address 0.0.0.0:80，no listening sockets available, shutting down
修改./apachectl权限:
sudo chown root:root apachectl
sudo chown root:root httpd
sudo chmod u+s apachectl
sudo chmod u+s httpd
?
cronolog可选
——————————————
cronolog安装
1, wget http://cronolog.org/download/cronolog-1.6.2.tar.gz
2, tar zxvf cronolog-1.6.2.tar.gz
3, cd cronolog-1.6.2
4, ./configure
5, make
6, sudo make install
7, which cronolog (查看是否安装成功)
