1、安装之前需要对内核进行优化：（四核，内存1024   32位系统 ）（安装之前的优化不会可以淘宝找人做做，30rmb或者20rmb）
    1.1关闭不需要的服务，可降低内存使用率（这个可以百度，我是百度）
    1.2内核参数优化
  

1. # Kernel sysctl configuration file for Red Hat Linux
   
2. #
   
3. # For binary values, 0 is disabled, 1 is enabled.  See sysctl(8) and
   
4. # sysctl.conf(5) for more details.
   
5. # Controls IP packet forwarding
   
6. net.ipv4.ip_forward = 0
   
7. # Controls source route verification
   
8. net.ipv4.conf.default.rp_filter = 1
   
9. # Do not accept source routing
   
10. net.ipv4.conf.default.accept_source_route = 0
    
11. # Controls the System Request debugging functionality of the kernel
    
12. kernel.sysrq = 0
    
13. # Controls whether core dumps will append the PID to the core filename.
    
14. # Useful for debugging multi-threaded applications.
    
15. kernel.core_uses_pid = 1
    
16. # Controls the use of TCP syncookies
    
17. net.ipv4.tcp_syncookies = 1
    
18. # Disable netfilter on bridges.
    
19. net.bridge.bridge-nf-call-ip6tables = 0
    
20. net.bridge.bridge-nf-call-iptables = 0
    
21. net.bridge.bridge-nf-call-arptables = 0
    
22. # Controls the default maxmimum size of a mesage queue

43. fs.file-max=65535
    
44. fs.file-max=65535
    
45. 
    
46. 
    
47. net.ipv4.tcp_keepalive_intvl = 75
    
48. net.ipv4.tcp_keepalive_probes = 9

54. net.ipv4.tcp_max_orphans = 163840
    
55. #以下参数是对iptables防火墙的优化，防火墙不开会提示，可以忽略不理。
    
56. net.ipv4.ip_conntrack_max = 25000000

推荐lnmpa   我安装完成后运行内存是170m

1 运行 yum install screen -y   （ 推荐使用xshell）
   （附件图片）
然后在xhsell中如下设置
完成后重新连接，这样就可以 离线安装程序了
2运行lnmp一键安装包（http://lnmp.org/install.html）（自带zend goard loader6.0  php5.2或者5.3）
wget -c http://soft.vpser.net/lnmp/lnmp1.1-full.tar.gz && tar zxf lnmp1.1-full.tar.gz && cd lnmp1.1-full && ./centos.sh
提示操作就行
3运行./apache.sh    安装lnmpa
4安装php5.4    ./upgrade_lnmpa_php.sh
5安装第三方扩展
推荐：
     1.1 ./eaccelerator.sh
     1.2 ./memcached.sh
以上就完成了飞飞侠或小淘客的环境配置

虚拟主机管理
1、LNMPA添加虚拟主机：/root/vhost.sh

2、删除虚拟主机，ssh执行：rm /usr/local/nginx/conf/vhost/域名.conf 同时需要：rm /usr/local/apache/conf/vhost/域名.conf
