apache+mod_jk 安装笔记

(0)源码安装
shell> tar xzvf httpd-2.2.10.tar.gz
shell> cd httpd-2.2.10

如果要装suexec支持cgi的sudo,则：
shell> ./configure --prefix=/usr/local/apache2 --enable-suexec --with-suexec-caller=daemon --with-suexec-docroot=/usr/local/apache2/cgi-bin

如果是媒体服务器的用户media，需要以下：
shell> ./configure --prefix=/usr/local/apache2 --enable-suexec --with-suexec-caller=media --with-suexec-docroot=/usr/local/apache2/cgi-bin

否则一般情况下：
shell> ./configure --prefix=/usr/local/apache2 --enable-module=so --enable-module=rewrite --enable-ssl=static --with-ssl=/usr/local/ssl //(ssl开启https)

#这里我们通过enable-module参数告诉设置脚本，我们需要启动so和 rewrite模块，so模块是用来提DSO支持的apache核心模块，而rewrite模块则是用意实现地址重写的模块，由于rewrite模块需要 DBM支持，如果在初次安装时没有编译进apache，以后需要用到时需要重新编译整个apache才可以实现。为此除非你可以确定以后不会用到 rewrite模块，否则还是建议你在第一次编译的时候把rewrite模块编译好。

shell> make
shell> make install
shell> vi /etc/rc.local , 写入：
### added by abiao
/usr/local/apache2/bin/apachectl start
### abiao end

shell> /usr/local/apache2/bin/apachectl start
如果碰到：httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
则修改httpd.conf的#ServerName www.example.com:80 为：
ServerName 192.168.10.253:80

设置开机自启动
cd /usr/local/apache2/bin/
cp apachectl /etc/rc.d/init.d/httpd
chmod 700 /etc/rc.d/init.d/httpd
vi /etc/rc.d/init.d/httpd
在 # |||||||||||||||||||| START CONFIGURATION SECTION |||||||||||||||||||下面添加下面三行|

#Comments to support chkconfig on RedHat Linux
#chkconfig: 2345 90 90
#description:http server
注意：前面的# 不能少,没有这三行，在使用chkconfig 时会提示你：service httpd does not support chkconfig

============================================================================

(01)mod_jk安装
拷贝 mod_jk-1.2.26-httpd-2.2.6.so 到 /usr/local/apache2/modules

编辑httpd.conf , 添加如下行：
LoadModule jk_module modules/mod_jk-1.2.26-httpd-2.2.6.so
JkWorkersFile conf/workers.properties
JkMountFile conf/uriworkermap.properties
JkLogFile logs/mod_jk.log
JkShmFile logs/jk-runtime-status
JkLogLevel warn

<Location /jkstatus>
Order Deny,Allow
Deny from all
# abiao's pc
Allow from 192.168.12.17
</Location>

在conf目录下创建workers.properties文件，添加：

# list the workers by name
worker.list=status, boss241, boss242, boss29, boss35, boss240, boss195, boss159, boss142

worker.status.type=status

# server 1

# ------------------------
worker.boss195.port=8009
worker.boss195.host=192.168.18.195

# server 7
# ------------------------
worker.boss159.port=8009

# ------------------------
worker.boss142.port=8009
worker.boss142.host=192.168.45.142
worker.boss142.type=ajp13

在conf目录下创建uriworkermap.properties文件，添加：

===============================================================================

(02) apache 支持中文URL路径浏览
复制 mod_encoding.so 和 mod_headers.so 文件到/usr/local/apache2/modules/目录下

shell> cd /root/abiao-disk
shell> tar -xzvf mod_encoding-20021209.tar.gz
shell> cd mod_encoding-20021209/lib
shell> ./configure
shell> make
shell> make install

shell> vi /usr/local/apache2/conf/httpd.conf
加入:
LoadModule headers_module modules/mod_headers.so
<IfModule mod_headers.c>
Header add MS-Author-Via "DAV"
</IfModule>
LoadModule encoding_module modules/mod_encoding.so
<IfModule mod_encoding.c>
EncodingEngine on
NormalizeUsername on
SetServerEncoding GBK
DefaultClientEncoding UTF-8 GBK GB2312
AddClientEncoding "(Microsoft .* DAV $)" UTF-8 GBK GB2312
AddClientEncoding "Microsoft .* DAV" UTF-8 GBK GB2312
AddClientEncoding "Microsoft-WebDAV*" UTF-8 GBK GB2312
</IfModule>

shell> /usr/local/apache2/bin/apachectl restart
=================================================================================

(2) 查看apache版本
# cd /usr/local/apache2/bin
./httpd -v
(3) 一旦服务器编译完成，就可以用以下命令列出所有已经被编译到服务器中的模块，包括MPM。
./httpd -l

如果启动apache 报错：
[root@localhost lib]# /usr/local/apache2/bin/apachectl restart
httpd: Syntax error on line 61 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/local/apache2/modules/mod_encoding.so into server: libiconv_hook.so.1: cannot open shared object file: No such file or directory
就要：
shell> vi /etc/ld.so.conf
加入：
/usr/local/lib

shell> ldconfig //让路径起作用
如果启动apache 报错：
[root@localhost httpd]# cd /usr/local/apache2/bin/
[root@localhost bin]# ./apachectl start
httpd: Syntax error on line 55 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/local/apache2/modules/libphp5.so into server: libmysqlclient.so.15: cannot open shared object file: No such file or directory

解决办法：让所有库自动给连5.0.84的client lib

cd /usr/lib
ln -s /usr/local/mysql/lib/libmysqlclient.so.15 libmysqlclient.so.15
ll | grep mysqls

（1）
启动 apachectl 时出错,说httpd.conf的53行有语法错误.libphp5.so模块无法载入.
错误信息如下:
Syntax error on line 53 of /usr/local/apache2/conf/httpd.conf:
Can not load /usr/local/apache2/modules/libphp5.so into server:
/usr/local/apache2/modules/libphp5.so:
Can't restore segment prot after reloc : Permission denied
解决: apache不能加载外挂php模块这是由SELinux的安全策略配置不当引起的.在Fedora Core 的官方网站上有相关的Apache/SELinux的策略调整文档.如果嫌麻烦,可以直接修改/etc/selinux/config 将SELinux禁用.
(2)
Syntax error on line 79 of /usr/local/httpd/conf/httpd.conf:
AddType requires at least two arguments,a mime type followed by one or more file extensions
解决：要加空格
(3)
启动 httpd：httpd: Syntax error on line 210 of /etc/httpd/conf/httpd.conf: Syntax error on line 6 of /etc/httpd/conf.d/auth_mysql.conf: Cannot load /etc/httpd/modules/mod_auth_mysql.so into server: libmysqlclient.so.15: cannot open shared object file: No such file or directory
[失败]
解决：看见上面的原因可能是我之前卸载rhel自带的mysql的过程中，强制卸载了一些依赖包，解决办法如下：
vi /etc/httpd/conf.d/auth_mysql.conf //进入相关文件，注释掉出错的第六行，解决OK

在设置的DocumentRoot目录下，添加一个phpinfo.php的文件来测试系统，程序代码如下：
<?
//filename: phpinfo.php
phpinfo();
?>
这时候在客户端浏览器中访问http://localhost/phpinfo.php应该出现php的参数表，至此所有系统安装完毕。

4 测试时发现不能解析php，具体表现为页面空白，但可以解析html(就是能出来apache刚安装好后的提示那个）
解决：<?php
phpinfo();
?>
？后少加了后缀php。这是php.ini没有设置好的原因
; Allow the <? tag. Otherwise, only <?php and <script> tags are recognized.
; NOTE: Using short tags should be avoided when developing applications or
; libraries that are meant for redistribution, or deployment on PHP
; servers which are not under your control, because short tags may not
; be supported on the target server. For portable, redistributable code,
; be sure not to use short tags.
short_open_tag = Off
把这个设置为ON也可以解决。。。。。。

*******************************************************************************

再个问题就是：浏览器显示错误信息如下：

Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0 Fatal error: Unknown: Failed opening required '/usr/local/httpd/htdocs/phpinfo.php' (include_path='.:/usr/local/lib/php') in Unknown on line 0


问题的原因是 : 你的phpinfo.php文件 在这个用户下不具有 可读的权限 通过 ls -l 查看 文件的权限 然后更改权限（添加读权限 chmod +r phpinfo.php）就不会出现这个问题了...
如果看到如图1的信息即表示成功了

如果重新起动APACHE出现:
Syntax error . line 232 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/local/apache2/modules/libphp5.so into server:
/usr/local/apache2/modules/libphp4.so: cannot restore segment prot after reloc: Permission denied
那就要按照下面的方法解决:

1.chcon -t texrel_shlib_t /usr/local/apache2/modules/*.so

============================================================
httpd -l
列出编译的模块文件。

httpd -M 查看已经编译了的模块:

如果要支持cgi 功能，请去掉配置文件此行前的注释
#AddHandler cgi-script .cgi
