Blog运行方案由Nginx+PHP-FPM切换到OpenLiteSpeed

Kotarou 未分类

Litespeed原本是一个商业软件,最近发布了开源版的Litespeed,减少了部分特性,但是开源版并不减少整体的稳定性和易用性.下面是几个我更换WebServer的原因.

1.Litespeed附带一个管理面板,可以很方便的对服务器进行管理,能很简单的添加/删除/编辑虚拟主机.

2.Litespeed支持Nginx所支持的大部分特性,例如,反向代理,等

3.Litespeed支持Nginx不支持的Spdy 3

4.Litespeed 兼容Apache的.htaccess Rewrite格式(虽然开源版不支持文件.htaccess).

又换回LNMP了.

Centos MariaDB 5.5.35 编译失败解决办法

Kotarou LINUX笔记

在某些Centos上编译MariaDB 5.5.35在make的时候可能会出现以下问题:

root@wsi:/root/src/mariadb-5.5.35# make
.......
[  8%] Building C object mysys/CMakeFiles/mysys.dir/my_context.c.o
cd /root/src/mariadb-5.5.35/mysys && /usr/bin/gcc  -DHAVE_CONFIG_H -Wall  -march=i686 -fPIC -O3 -DNDEBUG -DDBUG_OFF -I/root/src/mariadb-5.5.35/include -I/root/src/mariadb-5.5.35

使用以下pactch可以解决编译失败的问题.

Linux使用smartctl检查服务器硬盘状况

Kotarou LINUX笔记

1.安装smartmontools.

#CentOS
yum install smartmontools

2.查询通电时间及通电次数

[root@wsi ~]# smartctl -a /dev/sda | grep -E "Power_On_Hours|Power_Cycle_Count"
  9 Power_On_Hours          0x0012   100   100   000    Old_age   Always       -       3987
 12 Power_Cycle_Count       0x0032   100   100   000    Old_age   Always       -       24

3.错误日志查询

[root@wsi ~]# smartctl -l error /dev/sda
smartctl 5.43 2012-06-30 r3573 [x86_64-linux-2.6.32-042stab084.17] (local build)
Copyright (C) 2002-12 by Bruce Allen, http://smartmontools.sourceforge.net

=== START OF READ SMART DATA SECTION ===

4.完整检测

[root@wsi ~]# smartctl -t long /dev/sdb

Use smartctl -X to abort test.

#通过该命令进行磁盘的扩展彻底检查 (大约要持续数小时，应该在低负载进行如果发现错误，基本可以说明需要更换硬盘)

5.查看完整检测日志:

Cent0S Tunnelbroker IPV6隧道自动加载

Kotarou LINUX笔记

因为服务器ISP给的IPV6不知道什么原因挂掉了.不得不使用Tunnelbroker的IPV6隧道,但是如果使用官方介绍的Linux-net-tools方法进行设置的话,在重启服务器或者执行service network restart之后,IPV6设置会丢失,为了解决这个问题,在各种GOOGLE之后终于找到了一个完美的解决方案.

QQ20140202-2

1.编辑/etc/sysconfig/network,加入以下内容来打开IPV6和设置默认网关:

NETWORKING_IPV6=yes
IPV6_DEFAULTDEV="sit1"

2.编辑/etc/sysconfig/network-scripts/ifcfg-eth0,加入默认IPV6网关地址,请参考上图.
P.S:ifcfg-eth0为你的网卡配置文件,请根据自己的实际情况修改

IPV6ADDR=IPV6网关

3.创建/etc/sysconfig/network-scripts/ifcfg-sit1 配置文件

ONBOOT=yes
DEVICE=sit1
BOOTPROTO=none
IPV6INIT=yes
IPV6TUNNELIPV4=隧道服务器的IPV4
IPV6TUNNELIPV4LOCAL=本机的IPV4地址
IPV6ADDR=本机IPV6开始地址

4.设置完成后,执行/sbin/service network restart,IPV6隧道就应该可以正常工作了,并且在重启之后系统也可以自动加载IPV6地址.
