LAMP+LNMP安装注意问题及安装

一、LAMP安装注意事项

1. 必须先安装apache再安装 php,apache支持php需要生成libphp5.so 文件，需要编译时添加该语句 --with-apxs2=/usr/local/apache/bin/apxs
2. apache配置文件修改注意事项
   2.1. AllowOverride None　 #修改为：AllowOverride All （允许.htaccess）
   2.2.DirectoryIndex index.html #修改为：DirectoryIndex index.html index.htm Default.html Default.htm index.php（设置默认首页文件，增加index.php）
   2.3.MaxKeepAliveRequests 500 #添加MaxKeepAliveRequests 500 （增加同时连接数）
   2.4.设置工作目录 #说明: 搜索DocumentRoot, 修改为 DocumentRoot "/var/www/html" 搜索, 修改为 "/var/www/html">
   2.5. 设置默认文档 ： 索, 修改为 DirectoryIndex index.html index.php
   2.6.增加php类型 AddType application/x-gzip .gz .tgz在后面添加 AddType application/x-httpd-php .html .php
   2.6.#修改配置文件 vi /etc/httpd/httpd.conf
   #查找ServerName,将注释去掉 ServerName www.example.com:80 www.example.com->需要改的ip
   2.7.#添加到自启动
   echo "/usr/local/apache2/bin/apachectl start" >> /etc/rc.d/rc.sysinit #将apache添加到系统服务中
   cp /usr/local/apache2/bin/apachectl /etc/init.d/httpd
   vi /etc/rc.d/init.d/httpd
   #在#!/bin/sh后添加下面两行(包含"#")
   # chkconfig:2345 85 15
   # description:Apache
   #添加执行权限 chmod 755 /etc/init.d/httpd
   #添加到系统服务中 chkconfig --add httpd
   #开启apache service httpd start

*注：设置SELinux为permissive模式 命令行下 setenforce 0 立即生效，重启失效 修改配置文件后, 重启apache才能生效

二、LNMP安装
必须开启 --enbale-fpm

groupadd www
useradd -s /sbin/nologin -g www www

./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_spdy_module --with-http_gzip_static_module --with-ipv6 --with-http_sub_module  

make && make install
   软连接
ln -sf /usr/local/nginx/sbin/nginx /usr/bin/nginx

修改配置文件支持php
可把 root 改为想要的目录
打开一下 #

#location ~ \.php$ {
#            root           /home/wwwroot/;
#            fastcgi_pass   127.0.0.1:9000;
#            fastcgi_index  index.php;
#            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
#            include        fastcgi_params;
#        }

like this:


 location ~ \.php$ {
            root           /home/wwwroot/;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }

也可以把给段配置改为改
*$document_root指 定义的根目录

location ~\.php{
fastcgi_pass unix:/tmp/php-fcgi.sock; //下面解释
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi.conf;
}

*fastcgi_pass 里的 127.0.0.1:9000; 可改为unix:/tmp/php-fcgi.sock;
需要更改 php-fpm.conf 需要添加
group=www
user=www
listen=/tmp/php-fcgi.sock
listen.owner= www
listen.group =www

还要建立 /tmp/php-fcgi.sock; touch /tmp/php-fcgi.sock

chown www:www /tmp/php-fcgi.sock 赋予其权限

nginx -s reload

php-fpm 重启

配置文件 ：

---

server{

listen 8080;
server_name 192.168.139.134:8080;
index  index.html index.htm index.php;
root   /home/wwwroot/demo;

location ~\.php{

fastcgi_pass unix:/tmp/php-fcgi.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi.conf;

}

}

location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|mp4)$
        {
            expires    30d;

        }

        location ~ .*\.(js|css)?$
        {
            expires    12h;
        }
