memory allocator php,LNMP的安装
一、LNMP的安装
##先要下载,并根据不同系统进行安装:
wget -c http://soft.vpser.net/lnmp/lnmp1.2.tar.gz
tar zxvf lnmp1.2.tar.gz
cd lnmp1.0
./install.sh#开始进行安装操作
以上为下载及进入安装过程,以下为安装前简易设置,切记输入个其它域名及牢记mysql密码:

#按任意键,设置完成,正式进入安装,预计20-40分钟完成
常见lnmp管理命令:
#1.2版本以后,不需要再执行/root/lnmp了,可以在任意位置执行lnmp命令
lnmp#会出现一些提示信息
lnmp restart#重启
lnmp vhost add#添加网站绑定
lnmp database add#添加数据库信息
二,域名绑定详解
其实所谓的域名绑定,就是通过命令的形式,简易创建一个conf文件到/usr/local/nginx/conf/vhost下面,这个过程完全可以手工创建conf,或者,平时修改目录、域名等,直接修改conf文件,效果完全一样:
lnmp vhost add#执行lnmp添加网站命令
+-------------------------------------------+

Please enter domain(example: www.lnmp.org): vpsmm.com#输入绑定的主域名
======================================
Your domain: vpsmm.com
======================================
Do you want to addmore domain name? (y/n) y#是否绑定其它域名
Enter domain name(example: lnmp.org *.lnmp.org): www.vpsmm.com#输入其它域名
domain list: www.vpsmm.com
Please enter the directoryfor the domain: vpsmm.com
(Default directory: /home/wwwroot/vpsmm.com):#默认创建的网站文件所在目录
Virtual Host Directory: /home/wwwroot/vpsmm.com
===========================
Allow Rewrite rule? (y/n)
===========================
y#是否添加伪静态文件
Please enter the rewrite of programme:
wordpress,discuz,typecho,sablog,dabr rewrite was exist.

Allow access_log? (y/n)
===========================
n#是否启用日志文件
======================================================
Create database and MySQL user with same name (y/n)
======================================================
y#是否创建mysql数据库
verify your current MySQL root password: ****#输入安装时的mysql数据库root密码
Warning: Using a password on thecommand line interface can be insecure.
MySQL root password correct.
Enter database name: vpsmm_user#创建数据库用户名
Your will create a database and MySQL user with same name: vpsmm_user
Please enter passwordfor mysql user vpsmm_user: vpsmmpasswd
Your password: vpsmmpasswd#创建相应密码

Database Name: vpsmm_user
Createftp account: no
#以上为新创建网站的一些信息
================================================
三、自定义伪静态规则
如果lnmp默认的伪静态规则不能满足你的需要,或者,你要自行定义伪静态规则,可以新建一个conf文件,放置于 /usr/local/nginx/conf 下,在域名配置文件,即:/usr/local/nginx/conf/vhost/legcloud.com.conf 里引用。
server
{
listen 80;
server_name legcloud.com www.legcloud.com;#绑定的域名
index index.html index.htm index.php default.html default.htm default.php;#首页文件
root /home/legcloud.com;#网站存放目录
include wordpress.conf;#伪静态规则文件,可自定义成你需要的
location ~ .*\.(php|php5)?$
{
try_files $uri =404;
fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_index index.php;
include fcgi.conf;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}
location ~ .*\.(js|css)?$
{
expires 12h;
}
access_log off;
}
修改设置以后,一定要重新载入lnmp或者,重新载入nginx,以下任决命令都一样:
/root/lnmp reload#使用lnmp重新载入配置
/etc/init.d/nginx reload#只重新载入nginx配置,我一般用这个
四、自定义404、503等常见错误
不管是404还是503等常见错误,还是设置/usr/local/nginx/conf/vhost/legcloud.com.conf文件来完成:
listen 80;
server_name legcloud.com www.legcloud.com;
index index.html index.htm index.php default.html default.htm default.php;
root /home/legcloud.com;
error_page 404 /404.php;#放在这里,可自定义文件名,再重载nginx就可以了
include wordpress.conf;
五、判断当前域名并自动301到主域名
if ($host != 'vpsmm.com' ) {rewrite ^/(.*)$ http://www.vpsmm.com/$1 permanent;}
#判断当前域名,如果不是则自动301到主域名,放置于error_page ...;上下均可。
六、关闭或开启FSO等php函数
lnmp最新版,默认禁用了一些函数,例如fso等,可修改/usr/local/php/etc/php.ini
disable_functions = passthru,exec,system,chroot,scandir....
#----这是禁用函数,把不想禁用的删除即可----如果自用主机,最简单的修改方案:
disable_functions =
; passthru,exec,system,chroot,scandir....
#----设置为全部开启
修改后,使用/etc/init.d/php-fpm restart,重新启动php
七、升级PHP和NGINX版本
cd lnm0.9#进入lnmp安装目录
./upgrade_nginx.sh#升级nginx,只要输入你要升级的版本即可(可见nginx.org)
./upgrade_php.sh#升级php,只要输入你要升级的版本即可(可见php.net)
