yum方式安装lnmp centos

安装第三方软件源(epel、nginx、remi)

rpm -ivh http://download.fedora.redhat.com/pub/epel/6/x86_64/epel-release-6-7.noarch.rpm
rpm -ivh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

yum一键安装lnmp

yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2  glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap  openldap-devel nss_ldap openldap-clients openldap-servers

二、安装php和mysql

yum -y install php mysql mysql-server mysql-devel php-mysql php-cgi php-mbstring php-gd php-fastcgi

php参数配置

sed -i '/expose_php/{s/On/Off/g}' /etc/php.ini
sed -i '/display_errors/{s/On/Off/g}' /etc/php.ini
sed -i '/php_errors.log/{s/;//g}' /etc/php.ini
sed -i '/file_uploads/{s/On/Off/g}' /etc/php.ini
sed -i '/allow_url_fopen/{s/On/Off/g}' /etc/php.ini
sed -i '/allow_url_include/{s/On/Off/g}' /etc/php.ini
sed -i '/;date.timezone/{s/;//g;s/=/= Asia\/Shanghai/g}' /etc/php.ini
sed -i '/cgi.fix_pathinfo\=/{s/;//g;s/1/0/g}' /etc/php.ini
sed -i '/memory_limit/{s/128/64/g}' /etc/php.ini
sed -i '/safe_mode/{s/Off/On/g}' /etc/php.ini
php-fpm配置
sed -i 's/apache/nginx/g' /etc/php-fpm.d/www.conf
sed -i '/request_terminate_timeout/{s/;//g;s/0/30/g}' /etc/php-fpm.d/www.conf 

内核优化

echo "net.ipv6.conf.all.disable_ipv6 = 1"       >> /etc/sysctl.conf
echo "vm.swappiness = 25"           >> /etc/sysctl.conf
echo "net.ipv4.route.max_size = 524288 "        >> /etc/sysctl.conf
echo "net.core.somaxconn = 10240"           >> /etc/sysctl.conf
echo "net.ipv4.tcp_max_syn_backlog = 204800"    >> /etc/sysctl.conf
echo "net.core.netdev_max_backlog =  204800"    >> /etc/sysctl.conf
echo "net.ipv4.ip_local_port_range = 1024   65535"   >> /etc/sysctl.conf

echo "ulimit -SHn 65535" >> /etc/profile
cat >> /etc/security/limits.conf <<EOF
nginx               soft    nofile  65535
nginx               hard    nofile  65535
EOF

nginx基本优化

sed -i '/worker_processes/{s/1/4/g}' /etc/nginx/nginx.conf 
sed -i '/worker_processes/a\ worker_rlimit_nofile 65535;' /etc/nginx/nginx.conf
sed -i '/worker_connections/{s/1024/10240/g}' /etc/nginx/nginx.conf 
sed -i '/sendfile/a\ server_tokens off;' /etc/nginx/nginx.conf  
sed -i '/version/{s/\/\$nginx_version//g}' /etc/nginx/fastcgi_params  
sed -i '/events/a\    use epoll;' /etc/nginx/nginx.conf 

nginx的fpm基本配置，找到FASTCGI选项，去掉注释，修改下面这样
location ~ \.php$ {
    root  /var/www/html;
    fastcgi_pass  127.0.0.1:9000;
    #fastcgi_pass  unix:/tmp/php-fpm.sock;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include  fastcgi_params;
}
nginx页面设置

mkdir -p /www/html
sed -i 's#/usr/share/nginx/html#/www/html#g' /etc/nginx/nginx.conf sed -i 's/index.html/& index.php/' /etc/nginx/nginx.conf
 echo "<?php phpinfo();?>" /var/www/html/index.php
ysql配置

有条件的话，给mysql单独分个区作为datadir

[mysqld]

datadir=/data

其他参数可以参考/usr/share/mysql下的示例文件

mysql基本加固，（设置密码，限制访问等）

  
  
  
  

   
   
   
   
mysql_secure_installation 
  
  
  
  

启动服务

  
  
  
  

   
   
   
   
chkconfig nginx on 
   
   
   
   
chkconfig php-fpm on 
   
   
   
   
chkconfig mysqld on 
   
   
   
   
/etc/init.d/php-fpm start 
   
   
   
   
/etc/init.d/mysqld start 
   
   
   
   
/etc/init.d/nginx start 
  
  
  
  

iptables防火墙，需要根据自己设置，下面仅仅是个示例
cat >/root/firewall.sh <<EOF
 #!/usr/bin/env bash 
 modprobe ip_tables 
modprobe iptable_filter 
modprobe ipt_REJECT 
iptables -F 
iptables -X
