LNMMP：Memcache+LNMP
本次试验主要作用：
1、利用Nginx实现LNMP动静分离;
2、利用Memcache对php查询做缓存;
大致规划：
| 主机 | IP | 描述 |
| nginx | 192.168.0.111 | Nginx作为代理服务器实现动静分离 |
| php | 192.168.0.112 | 处理动态请求 |
| httpd | 192.168.0.113 | 处理静态请求 |
| mariadb | 192.168.0.114 | 数据库存储 |
| memcache | 192.168.0.115 | 对php查询做缓存 |

二、配置Nginx整合到php
Nginx的模块和变量相当多；这里无法一一介绍清楚；直接给出官方连接；
详细可以查阅：http://nginx.org/en/docs/ http://wiki.nginx.org/Modules
配置Nginx:
node1配置：
[root@node1 html]# vim /etc/nginx/nginx.conf
#user nobody;
worker_processes 4; worker进程数
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 1024; 每个进程处理请求数
}
http {
include mime.types;
default_type application/octet-stream;
#proxy_cache_path /cache/nginx levels=1:2 keys_zone=web:10m inactive=12h max_size=1g;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 5; 持久连接 5s
#gzip on;
server { 配置虚拟服务器
listen 80;
root /var/www/html; #站点路径
server_name www.soul.com;
#charset koi8-r;
#access_log logs/host.access.log main;
location / { #属性，正常请求全部代理到node3上
index index.php index.html index.htm;
proxy_pass http://192.168.0.113;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location ~ \.php$ { #这里就是整合php;以.php结尾的文件
fastcgi_pass 192.168.0.112:9000; #以fastcgi协议代理到node2的9000端口
fastcgi_index index.php; #如果没有参数；则以index.php为参数
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params; #fastcgi的配置参数文件
}
}
修改/etc/nginx/fastcgi_params，将其内容替换：
[root@node1 ~]# vim /etc/nginx/fastcgi_params fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name;
配置node3
[root@node3 ~]# rpm -q httpd httpd-2.2.15-29.el6.centos.x86_64 [root@node3 ~]# service httpd start Starting httpd: [ OK ] [root@node3 ~]#
配置完成后；对nginx和fpmd进行重启并提供主页面进行测试；这里现在就不测试
三、配置memcache
下面开始配置memcach
#在node5上直接yum安装memcached
# yum -y install memcached
[root@node5 ~]# rpm -ql memcached 安装完成查看生成的文件
/etc/rc.d/init.d/memcached
/etc/sysconfig/memcached #配置文件
/usr/bin/memcached
/usr/bin/memcached-tool
[root@node5 ~]# vim /etc/sysconfig/memcached
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"
OPTIONS="" #其实很简单；不需要任何配置；直接启动
[root@node5 ~]# ss -tunl | grep 11211
udp UNCONN 0 0 *:11211 *:*
udp UNCONN 0 0 :::11211 :::*
tcp LISTEN 0 128 :::11211 :::*
tcp LISTEN 0 128 *:11211 *:*
在node2上安装php的memcache的扩展
[root@node2 ~]# rm -rf memcache-2.2.7 [root@node2 ~]# tar xf memcache-2.2.7.tgz [root@node2 ~]# cd memcache-2.2.7 [root@node2 memcache-2.2.7]# ls config9.m4 CREDITS memcache_consistent_hash.c memcache_queue.c memcache_standard_hash.c config.m4 example.php memcache.dsp memcache_queue.h php_memcache.h config.w32 memcache.c memcache.php memcache_session.c README [root@node2 memcache-2.2.7]# /usr/local/php/bin/phpize [root@node2 memcache-2.2.7]# ./configure --with-php-config=/usr/local/php/bin/php-config --enable-memcache [root@node2 memcache-2.2.7]# vim /etc/php.ini extension = /usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/memcache.so #添加如上一行；注意上述路径是编译后生成的路径
提供测试文件测试：
#提供两个文件；一个html；一个php
#该文件放在node2，node3各一份；
[root@node2 ~]# vim /var/www/html/index.html
<h1>This is test page</h1>
[root@node2 ~]# vim /var/www/html/index.php
<?php #这里测试memcache是否正常连接
$mem = new Memcache;
$mem->connect("192.168.0.115", 11211) or die("Could not connect");
$version = $mem->getVersion();
echo "Server's version: ".$version."<br/>\n";
$mem->set('hellokey', 'Hello World', 0, 600) or die("Failed to save data at the memcached server");
echo "Store data in the cache (data will expire in 600 seconds)<br/>\n";
$get_result = $mem->get('hellokey');
echo "$get_result is from memcached server.";
?>
<?php
phpinfo(); #php测试页面
?>
上述页面显示的memcache连是正常的；且也显示该网页是来自node2.soul.com这台主机的
测试正常访问
测试html页面正常返回。此处也给php安装了xcache；
安装过程就不再赘述；前面的博客都有详解。
到此；前面的nginx配置已完成；下面配置mariadb。
四、安装mariadb
MariaDB的安装与mysql一样没有任何区别；只是名称不一样
anaconda-ks.cfg install.log drbd-8.4.3-33.el6.x86_64.rpm install.log.syslog drbd-kmdl-2.6.32-431.el6-8.4.3-33.el6.x86_64.rpm mariadb-10.0.10-linux-x86_64.tar.gz [root@node4 ~]# [root@node4 ~]# tar xf mariadb-10.0.10-linux-x86_64.tar.gz -C /usr/local/ #剩下步骤就是依次做个软连接到mysql #更改权限；建议使用LVM作为存储 #存储目录权限也需要更改 #初始化 #复制启动脚本和配置文件；更改下配置文件；启动 [root@node4 ~]# mysql Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 5 Server version: 10.0.10-MariaDB-log MariaDB Server Copyright (c) 2000, 2014, Oracle, SkySQL Ab and others. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. MariaDB [(none)]> use mysql Database changed MariaDB [mysql]> grant all privileges on *.* to 'root'@'192.168.0.%' identified by '123456'; MariaDB [mysql]> flush privileges; #授权php主机可以连接 #到此mysql配置也结束
可以测试php是否可以连接mariadb
[root@node2 ~]# vim /var/www/html/index.php
#添加如下信息
<?php
$link = mysql_connect('192.168.0.114','root','123456');
if($link)
echo "Success...";
else
echo "Failure...";
mysql_close;
?>
访问测试
五、安装论坛测试
在node2,node3上各放一个论坛程序
然后访问安装
测试安装正常。现在来看下memcache缓存的状态；
[root@node2 ~]# cd /var/www/html/ [root@node2 html]# ls Discuz_X3.1_SC_UTF8.zip index.html index.php memadmin readme upload utility [root@node2 html]#
查看memcache的详细信息；此处都有统计。
到此；memcache+lnmp已配置完成。
如有错误；恳请指正！
