make[1]: *** [xml/apr_xml.lo] Error 1
make[1]: Leaving directory `/home/test/apr-util-1.6.1'
make: *** [all-recursive] Error 1
错误原因:缺少xml 的解析器
解决方法:yum -y install expat-devel
----------------------------------------------------------------------------------
(2)configure 时 error: APR not found
错误详情:
configure:
checking for APR… no
configure: error: APR not found. Please read the documentation.
错误原因:没有指定 Apache 必需组件 APR 或没有加–with-apr 选项指定 APR
的安装位置。
解决方法:安装 APR 并且加-–with-apr 选项指定正确的位置。
----------------------------------------------------------------------------------
(3)configure 时-–with-apr 选项不正确
错误详情:
configure:
checking for APR… configure: error: –with-apr requires a directory
or file to be provided
configure:
checking for APR… configure: error: the –with-apr parameter is
incorrect. It must specify an install prefix, a build directory, or
an apr-config file.
错误原因:-–with-apr 选项不能为空或者指定的 APR 的位置不正确
解决方法:指定正确的 APR 选项。其实系统中已经使用 yum 安装了 APR,却不
知道如何指定 yum 安装的 APR 的位置,故出此错误,也可以进行手动源代码编译安装
APR来解决这个错误。
----------------------------------------------------------------------------------
(4)configure 时 error: APR-util not found
错误详情:
configure:
checking for APR-util… no
configure: error: APR-util not found. Please read the documentation.
错误原因:没有安装 Apache 必需组件 APR-util 或没有加–with-apr-util 选
项指定 APR-util 的位置
解决方法:-–with-apr-util 选项指定正确的安装位置

(5)configure 时 error: pcre-config for libpcre not found
错误详情:
checking for pcre-config… false
configure: error: pcre-config for libpcre not found. PCRE is required
and available from http://pcre.org/
错误原因:没有安装 Apache 必需组件 PCRE 或没有加–with-pcre 选项指定
PCRE 的安装位置。
解决方法:安装 PCRE 并且加–with-pcre 选项指定正确的安装位置
----------------------------------------------------------------------------------
(6)configure 时 error: Did not find pcre-config script at

5.7 CentOS7 实战源码部署nginx网站服务器
简介:实战演练nginx网站服务器的搭建
nginx 简介:
Nginx的优点:
Nginx的缺点:
编译安装:
安装gcc编译环境:
yum install -y gcc-c++
安装zlib-devel库:
yum install -y zlib-devel
安装OpenSSL密码库:
yum install -y openssl openssl-devel
错误原因: httpd 2.4.39 不支持 pcre2?
解决方法:下载 pcre-8.43 安装即可。
----------------------------------------------------------------------------------
(7)启动 Apache 时提示设置 ServerName
错误详情:
AH00558: httpd: Could not reliably determine the server's fully qualified domain
name, using localhost.localdomain. Set the 'ServerName' directive globally to
suppress this message
错误原因:没有设置服务器名称
解决方法:vi /usr/local/apache/etc/httpd.conf
简介:实战演练nginx网站服务器的搭建
1.高并发量:根据官方给出的数据,能够支持高达 50,000 个并发连接数的响应
2.内存消耗少:处理静态文件,同样起web 服务,比apache 占用更少的内存及资源,所有它是轻量级的
3.简单稳定:配置简单,基本在一个conf文件中配置,性能比较稳定,可以7*24小时长时间不间断运行
4.模块化程度高:Nginx是高度模块化的设计,编写模块相对简单
5.负载均衡服务器:Nginx可以做高并发的负载均衡,且Nginx是开源免费的,如果使用F5等硬件来做负载均衡,硬
件成本比较高
6.可移植性高:Nginx代码完全用C语言编写
1.动态处理差:nginx处理静态文件好,耗费内存少,但是处理动态页面比较差
2.rewrite弱:虽然nginx支持rewrite功能,但是相比于Apache来说,Apache比nginx 的rewrite 强大
安装gcc编译环境:
yum install -y gcc-c++
安装zlib-devel库:
yum install -y zlib-devel
安装OpenSSL密码库:
yum install -y openssl openssl-devel
安装pcre正则表达式库:
[root@localhost apache_test] wget https://ftp.pcre.org/pub/pcre/pcre-8.44.tar.gz
tar -xf pcre-8.44.tar.gz
cd pcre-8.44
mkdir -p /usr/local/pcre
./configure --prefix=/usr/local/pcre
make && make install
wget http://nginx.org/download/nginx-1.18.0.tar.gz
mkdir -p /usr/local/nginx
tar -xf nginx-1.18.0.tar.gz
cd nginx-1.18.0
./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --with-pcre
make -j4 && make install
启动:
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
测试:
/usr/local/nginx/sbin/nginx -t
关闭:
/usr/local/nginx/sbin/nginx -s stop
打开浏览器测试能否访问到测试页面
简介:实战演练mysql数据库服务器的搭建
mysql简介:
mysql是一个开源的关系型数据库管理系统,现在是oracle公司旗下的一款产品,由C和C++语言编写,可移植性高。支持在多种操作系统上安装,最常见有AIX,linux,window。mysql因为开源免费,所以受到了目前互联网行业的欢 迎。以mysql作为数据库,linux系统作为操作系统,apache或者nginx作为web服务器,perl/php/python作为服务端 的脚本解释器,就可以搭建起一个免费的网站。被业界称为LNMP或者LAMP
准备工作:
磁盘空间剩余量达到15GB,内存2G以上,确保依赖组件安装完毕,安装mysql5.7.17一致,centos 7
关闭selinux,关闭防火墙:
systemctl stop firewalld.service
vi /etc/selinux/config
SELINUX=disabled
安装cmake工具:
yum -y install cmake
下载boost路径(mysql5.7.17的必需依赖组件):
tar -xf boost_1_59_0.tar.gz
yum安装其它依赖组件:
yum -y install gcc gcc-c++ bzip2 bzip2-devel bzip2-libs python-devel ncurses ncurses-devel openssl openssl-devel

简介:实战演练php服务的搭建
[root@localhost oceanshadow] yum -y install gcc gcc-c++ bzip2 bzip2-devel bzip2-libs python-devel ncurses ncursesdevel openssl openssl-devel
yum install -y libxml2-devel #安装依赖组件
[root@localhost oceanshadow] wget https://www.php.net/distributions/php-5.5.35.tar.gz #下载php源码
tar -xf php-5.5.35.tar.gz && cd php-5.5.35 #解压php并进入解压后php包:
[root@localhost php-5.5.35] mkdir -p /usr/local/php
[root@localhost php-5.5.35] ./configure --prefix=/usr/local/php/ --enable-fpm --with-config-file=/usr/local/php/etc
[root@localhost php-5.5.35 make -j 4 && make install #编译安装
[root@localhost oceanshadow] cd /home/oceanshadow/php-5.5.35/
[root@localhost php-5.5.35] cp -a php.ini-production /usr/local/php/etc/php.ini
[root@localhost php-5.5.35] cp -a /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
[root@localhost oceanshadow] /usr/local/php/sbin/php-fpm #启动
php的默认端口是:9000
[root@localhost oceanshadow] cd /usr/local/php/sbin && pkill php-fpm #关闭
[root@localhost oceanshadow] ps -ef | grep php #查看pipd
root 69941 1 0 15:51 ? 00:00:00 php-fpm: master process (/usr/local/php/etc/php-fpm.conf)
nobody 69942 69941 0 15:51 ? 00:00:00 php-fpm: pool www
nobody 69943 69941 0 15:51 ? 00:00:00 php-fpm: pool www
root 69970 2336 0 15:54 pts/1 00:00:00 grep --color=auto php
[root@localhost oceanshadow] netstat -tunlp | grep 69941 #查看监听端口
tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 69941/php-fpm: mast
修改nginx配置文件并添加以下内容:vi /usr/local/nginx/conf/nginx.conf
location ~ \.php$ {
root /usr/local/nginx/html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
修改后对nginx进行重启:/usr/local/nginx/sbin/nginx -s reload
FastCGI是 一个 在HTTP服务器和动态脚本语言间通信的接口
fastcgi_pass 127.0.0.1:9000; #设置监听端口
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;#设置脚本文件请求的路径
include fastcgi_params; #引入fastcgi的配置文件
vi /usr/local/nginx/html/index.php
<?php
phpinfo();
?>
