build：

yum install readline-devel pcre-devel openssl-devel rpm-build
rpmbuild -ba openresty.spec

安装打包的rpm程序：

rpm -ivh ~/rpmbuild/RPMS/x86_64/openresty-1.4.3-4.el6.x86_64.rpm

CentOS使用remi源安装最新版PHP

发布时间：January 26, 2014 // 分类：CentOS // No Comments

remi：

rpm -ivh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

CentOS5:

rpm -ivh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-5.rpm

CentOS7：

rpm -ivh http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm

安装后源默认禁用，如需启用可修改remi.repo或：

yum --enablerepo=remi-php55 install php

src:

http://rpms.famillecollet.com/SRPMS/

webtatic：

rpm -ivh http://repo.webtatic.com/yum/el6/latest.rpm

src:

http://repo.webtatic.com/yum/el6/SRPMS/

CentOS6使用Yum源安装LNMP

发布时间：December 25, 2013 // 分类：Nginx,CentOS // No Comments

编译安装LNMP太繁琐，不易部署和管理，通过系统源安装最很方便，Centos官方源软件包较少，需先安装EPEL源。
安装MysQL：

yum install mysql-server
/etc/init.d/mysqld start
chkconfig mysqld on
/usr/bin/mysqladmin -u root password 'newpasswd'

安装PHP：

yum install php-fpm php-cli php-mysqlnd php-pdo php-xml php-gd php-opcache
/etc/init.d/php-fpm start
chkconfig php-fpm on

安装Nginx：

yum install nginx
/etc/init.d/nginx start
chkconfig nginx on

VMware更新后Centos6网络device "eth0" does not seem to be present解决

发布时间：December 27, 2012 // 分类：CentOS,VMware // No Comments

VMware升级到9后顺便更新了下Virtual Machine，再次启动Centos6虚拟机后不能启动网络，提示以下错误：

device "eth0" does not seem to be present, delaying initialization

原因是Centos6使用udev动态管理设备文件将MAC地址和网卡名称对应记录在udev的规则脚本中，VMware升级后虚拟机网卡MAC会改变，这样系统会认为网卡是新增的并命名为eth1，查看如下：

ip add
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000
    link/ether 00:0c:29:ce:c0:1e brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.13/24 brd 192.168.1.255 scope global eth1
    inet6 fe80::20c:29ff:fece:c01e/64 scope link

解决方法1，修改网络配置文件设备eth0为eth1：

cat /etc/sysconfig/network-scripts/ifcfg-eth0 
DEVICE="eth1"
BOOTPROSTO=static
IPADDR=192.168.1.13
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
ONBOOT="yes"

解决方法2，修改udev记录的mac与网卡名称对应规则：

cat /etc/udev/rules.d/70-persistent-net.rules 
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:ce:c0:1e", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

CentOS调整默认启动的TTY终端数量

发布时间：December 26, 2012 // 分类：CentOS // No Comments

CentOS默认启动6个TTY，在控制台下可用Alt+[F1—F6]键在不同的终端之间切换，通过SSH虚拟终端管理远程服务器是用不到这些的，可减少启动的TTY数量减少系统资源占用。
CentOS5修改配置文件注释禁止启动的TTY即可：

cat /etc/inittab
#2:2345:respawn:/sbin/mingetty tty2
#3:2345:respawn:/sbin/mingetty tty3
#4:2345:respawn:/sbin/mingetty tty4
#5:2345:respawn:/sbin/mingetty tty5
#6:2345:respawn:/sbin/mingetty tty6

CentOS6下修改启动的TTY数量：

sed -i 's/\/dev\/tty\[1-6\]/\/dev\/tty\[1-1\]/g' /etc/init/start-ttys.conf 
sed -i 's/\/dev\/tty\[1-6\]/\/dev\/tty\[1-1\]/g' /etc/sysconfig/init
#修改为启动1个TTY

关闭指定终端：

initctl stop tty TTY=/dev/ttyn

踢出指定终端用户：

pkill -kill -t ttyn
