Nginx+PHP(FastCGI)+MySQL在小内存VPS(t1.micro)上的安装配置与优化

时间:2022-06-30 18:46:08 编辑:袖梨 来源:一聚教程网

背景介绍:
以前,因为AWS EC2的价格比较昂贵而租用了其它国外小厂商的VPS,在使用了3年多之后,发现AWS EC2的价格居然比现在正在使用的VPS要便宜很多。
全球线路与速度最理想的日本节点的t1.micro型号,选择3年长期合约的价格在2500元人民币左右,一年下来也不到900元,所以就打算将Blog迁移到AWS EC2上。
之前在部署VPS环境的时候,基本上是完整的参考了张宴的两篇文档,包括操作系统的选择也是相同的。

但这一次我想采用目前较新的CentOS 6.4 minimal x86_64。
同时选择版本最新的Nginx,PHP以及MySQL,引入EPEL仓库来简化安装与部署过程中对额外的依赖软件的安装,优化一些原来的工作方式,比如创建服务管理脚本来启动/停止Nginx与MySQL,使用logrotate来切割日志等;
经过了一番折腾,在填了不少的坑之后,终于成功的完成了新环境的部署,感觉非常不错。

下面,就是此次的整个安装配置过程:
1. 安装常用工具
yum install -y vim wget unzip screen tree mlocate

2. 安装编译工具
yum install -y gcc gcc-c++ autoconf patch cmake automake

3. 安装EPEL仓库
yum install -y http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

yum install -y bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel unixODBC unixODBC-devel
yum install -y krb5-libs krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel
yum install -y libgcrypt libgcrypt-devel libtool
yum install -y libmcrypt libmcrypt-devel mhash mhash-devel mcrypt pcre pcre-devel

9.7 启动Nginx服务
/webserver/init.d/nginx start

10. 优化系统内核参数
vim /etc/sysctl.conf

# For Nginx
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog = 32768
net.core.somaxconn = 32768
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.ip_local_port_range = 1024 65535

sysctl -p

vim /etc/security/limits.conf

*                -       nofile          32768
*                -       nproc           32768

11. 创建交换分区
dd if=/dev/zero of=/opt/swapfile bs=1M count=256
mkswap /opt/wapfile
swapon /opt/swapfile

vi /etc/fstab

/opt/swapfile           swap    swap    defaults        0 0

12. 配置logrotate切割日志
yum install -y logrotate
vim /etc/logrotate.d/blog

/webserver/blog/logs/eric_access.log
{
  daily
  rotate 7
  missingok
  notifempty
