马哥linux运维学习笔记-编译安装LAMP之php-5.4.13、xcache-2.0及使用ab命令实现压力测试

发布时间：2019-02-08 09:11:56编辑：雪饮阅读（）

整合php5.4.13+apache2.4.4:

[root@localhost ~]# cp /usr/local/src/php-5.4.13/php.ini-production /etc/php.ini

在httpd主机中心配置文件的mime_module模块中新增配置项

AddType application/x-httpd-php .php

AddType application/x-httpd-php-source .phps

同配置文件中dir_module模块中添加php默认页索引

<IfModule dir_module>

    DirectoryIndex index.php index.html

</IfModule>

编译xcache2.0.0

[root@localhost xcache-2.0.0]# /usr/local/php/bin/phpize

[root@localhost xcache-2.0.0]# ./configure --enable-xcache --with-php-config=/usr/local/php/bin/php-config

[root@localhost xcache-2.0.0]# cp xcache.ini /etc/php.d/

[root@localhost xcache-2.0.0]# head /etc/php.d/xcache.ini

[xcache-common]

;; install as zend extension (recommended), normally "$extension_dir/xcache.so"

zend_extension = /usr/local/php/lib/php/extensions/no-debug-zts-20100525/xcache.so

; zend_extension_ts = /usr/local/lib/php/extensions/non-debug-zts-xxx/xcache.so

;; For windows users, replace xcache.so with php_xcache.dll

;zend_extension_ts = c:/php/extensions/php_xcache.dll

;; or install as extension, make sure your extension_dir setting is correct

; extension = xcache.so

;; or win32:

; extension = php_xcache.dll

然后重启apache

虚拟主机

在中心主机配置文件中去除Include /etc/httpd/extra/httpd-vhosts.conf的注释

并注释DocumentRoot "/usr/local/apache/htdocs"

虚拟主机配置文件配置如：

<VirtualHost *:80>

    ServerName www.a.org

    DocumentRoot "/www/a.org"

    <Directory "/www/a.org">

        Options none

        AllowOverride none

        Require all granted

    </Directory>

    ErrorLog "/var/log/httpd/a.org-error_log"

    CustomLog "/var/log/httpd/a.org-access_log" combined

</VirtualHost>

<VirtualHost *:80>

    ServerName www.b.net

    DocumentRoot "/www/b.net"

    <Directory "/www/b.net">

        Options none

        AllowOverride none

        Require all granted

    </Directory>

    ErrorLog "/var/log/httpd/b.net-error_log"

    CustomLog "/var/log/httpd/b.net-access_log" combined

</VirtualHost>

创建相关目录

[root@localhost xcache-2.0.0]# mkdir -p /www/a.org

[root@localhost xcache-2.0.0]# mkdir -p /www/b.net

[root@localhost xcache-2.0.0]# mkdir -p /var/log/httpd

创建对应html

[root@localhost xcache-2.0.0]# cat /www/a.org/index.html

this is www.a.org

[root@localhost xcache-2.0.0]# cat /www/b.net/index.html

this is www.b.net

增加hosts解析

[root@localhost xcache-2.0.0]# cat /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1               localhost.localdomain localhost

::1             localhost6.localdomain6 localhost6

192.168.1.9     www.a.org www.b.net

重启apache

[root@localhost xcache-2.0.0]# /usr/local/apache/bin/apachectl restart

ab测试

解决ab测试“Too many open files”问题

问题：

[root@localhost xcache-2.0.0]# /usr/local/apache/bin/ab -c 2000 -n 10000 http://                                                                                                                           www.a.org/index.html

Benchmarking www.a.org (be patient)

socket: Too many open files (24)

解决：

ab测试是一个客户端应用，出现该错误是因为打开的页面数超过了客户端所在系统所限制的最大页面数，提示该限制即可

[root@localhost xcache-2.0.0]# ulimit -n 10000

忽略错误

问题：
