centos 安装 nss?centos哪个版本建站好

大家好,今天给各位分享centos 安装 nss的一些知识,其中也会对centos哪个版本建站好进行解释,文章篇幅可能偏长,如果能碰巧解决你现在面临的问题,别忘了关注本站,现在就马上开始吧!

centos5 源码安装Nginx + mysql + apache + php的方法

主要依照的是张宴的一篇博文《》,安装的软件是也是从他提供的列表中下载,这里都是tar.gz格式,如果更希望是rpm格式的话,提供一个网址《》这里列出了比较完全的下载包。

我安装的系统:Centos5

1、下载;

我安装的下载来自张宴博文下的地址,下载保存的是home下自己目录的一个文件夹下:

复制代码

   

代码如下:

cd/home/xuxx/software

   wget

   wget

   wget

   wget

   wget

   wget

   wget

   wget

   wget

   wget

   wget

   wget

   wget

   wget

2、准备编译安装环境,需要编译源码用到gc++

建议如果是新安装的系统,使用yum upgrade更新下系统。

复制代码

   

代码如下:

sudo-s

   LANG=C

   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

注意:这里所有的命令是一行的而不能有换行符,如果是copy的时候,注意要去处该换行符

确保安装成功!才能正确使用编译。

3、安装:

一、安装PHP 5.2.8(FastCGI模式)

1、编译安装PHP 5.2.8所需的支持库:

1] libiconv库

复制代码

   

代码如下:

tar zxvf libiconv-1.13.tar.gz

   cd libiconv-1.13/

   ./configure--prefix=/usr/local

   make

   make install

   make clean

   make distclean

   cd../

make clean和make distclean都是删除安装过程中生成的缓存文件。当然如果你不介意放着也可以跳过这两步清理操作。

2]libmcrypt库

复制代码

   

代码如下:

tar zxvf libmcrypt-2.5.8.tar.gz

   cd libmcrypt-2.5.8/

   ./configure

   make

   make install

   make clean

   make distclean

   /sbin/ldconfig

   cd libltdl/

   ./configure--enable-ltdl-install

   make

   make install

   make clean

   make distclean

   cd

3] mhash库

复制代码

   

代码如下:

tar zxvf mhash-0.9.9.9.tar.gz

   cd mhash-0.9.9.9/

   ./configure

   make

   make install

   cd../

4]mcrypt库

注意:因为该库和libmcrypt有依赖性,所以在安装前必须知道libmcrypt,否则的话会出现:

错误

复制代码

   

代码如下:

checking for libmcrypt– version= 2.5.0…

   ***‘libmcrypt-config–version’ returned 2.4.0, but LIBMCRYPT(2.5.8)

   *** was found! If libmcrypt-config was correct, then it is best

   *** to remove the old version of LIBMCRYPT. You may also be able to fix the error

   *** by modifying your LD_LIBRARY_PATH enviroment variable, or by editing

   ***/etc/ld.so.conf. Make sure you have run ldconfig if that is

   *** required on your system.

   *** If libmcrypt-config was wrong, set the environment variable LIBMCRYPT_CONFIG

   *** to point to the correct copy of libmcrypt-config, and remove the file config.cache

   *** before re-running configure

   configure: error:*** libmcrypt was not found

是因为path的问题,所以执行:

复制代码

   

代码如下:

ln-s/usr/local/lib/libmcrypt.la/usr/lib/libmcrypt.la

   ln-s/usr/local/lib/libmcrypt.so/usr/lib/libmcrypt.so

   ln-s/usr/local/lib/libmcrypt.so.4/usr/lib/libmcrypt.so.4

   ln-s/usr/local/lib/libmcrypt.so.4.4.8/usr/lib/libmcrypt.so.4.4.8

   ln-s/usr/local/lib/libmhash.a/usr/lib/libmhash.a

   ln-s/usr/local/lib/libmhash.la/usr/lib/libmhash.la

   ln-s/usr/local/lib/libmhash.so/usr/lib/libmhash.so

   ln-s/usr/local/lib/libmhash.so.2/usr/lib/libmhash.so.2

   ln-s/usr/local/lib/libmhash.so.2.0.1/usr/lib/libmhash.so.2.0.1

   ln-s/usr/local/bin/libmcrypt-config/usr/bin/libmcrypt-config

然后再安装:

复制代码

   

代码如下:

tar zxvf mcrypt-2.6.8.tar.gz

   cd mcrypt-2.6.8/

   /sbin/ldconfig

   ./configure

   make

   make install

   cd../

二、安装mysql

复制代码

   

代码如下:

/usr/sbin/groupadd mysql

   /usr/sbin/useradd-g mysql xxx

   unzip mysql-5.1.33.zip

   cd mysql-5.1.33/

   ./configure--prefix=/usr/local/webserver/mysql/--enable-assembler--with-extra-charsets=complex--enable-thread-safe-client--with-big-tables

   --with-readline--with-ssl--with-embedded-server--enable-local-infile--with-plugins=innobase

   make

   make install

   make clean

   make distclean

   chmod+w/usr/local/webserver/mysql

   chown-R xxx:mysql/usr/local/webserver/mysql

   cp support-files/my-medium.cnf.sh/usr/local/webserver/mysql/my.cnf

   cd../

注意:这里编译./configure命令是一行的而不能有换行符,如果是copy的时候,注意要去处该换行符

在最后一步拷贝的时候,我安装完在support-files下没有my-medium.cnf而只有my-medium.cnf.sh所以将这个文件拷贝过去。

@张宴原文:

附:以下为附加步骤,如果你想在这台服务器上运行MySQL数据库,则执行以下两步。如果你只是希望让PHP支持MySQL扩展库,能够连接其他服务器上的MySQL数据库,那么,以下两步无需执行。

①、以xxx用户帐号的身份建立数据表:

复制代码

   

代码如下:

/usr/local/webserver/mysql/bin/mysql_install_db--basedir=/usr/local/webserver/mysql--datadir=/usr/local/webserver/mysql/data--user=xxx

②、启动MySQL(最后的表示在后台运行)

复制代码

   

代码如下:

/bin/sh/usr/local/webserver/mysql/bin/mysqld_safe--defaults-file=/usr/local/webserver/mysql/my.cnf

3、编译安装PHP(FastCGI模式)

复制代码

   

代码如下:

tar zxvf php-5.2.8.tar.gz

   gzip-cd php-5.2.8-fpm-0.5.10.diff.gz| patch-d php-5.2.8-p1

   cd php-5.2.8/

   ./configure--prefix=/usr/local/webserver/php--with-config-file-path=/usr/local/webserver/php/etc--with-mysql=/usr/local/webserver/mysql

   --with-mysqli=/usr/local/webserver/mysql/bin/mysql_config--with-iconv-dir=/usr/local--with-freetype-dir--with-jpeg-dir--with-png-dir--with-zlib

   --with-libxml-dir=/usr--enable-xml--disable-rpath--enable-discard-path--enable-safe-mode--enable-bcmath--enable-shmop--enable-sysvsem

   --enable-inline-optimization--with-curl--with-curlwrappers--enable-mbregex--enable-fastcgi--enable-fpm--enable-force-cgi-redirect

   --enable-mbstring--with-mcrypt--with-gd--enable-gd-native-ttf--with-openssl--with-mhash--enable-pcntl--enable-sockets--with-ldap

   --with-ldap-sasl

   make ZEND_EXTRA_LIBS='-liconv'

   make install

   cp php.ini-dist/usr/local/webserver/php/etc/php.ini

   cd../

注意:这里./configure命令是一行的而不能有换行符,如果是copy的时候,注意要去处该换行符

4、编译安装PHP5扩展模块--可选安装

复制代码

   

代码如下:

tar zxvf memcache-2.2.5.tgz

   cd memcache-2.2.5/

   /usr/local/webserver/php/bin/phpize

   ./configure--with-php-config=/usr/local/webserver/php/bin/php-config

   make

   make install

   make clean

   make distclean

   cd../

   tar jxvf eaccelerator-0.9.5.3.tar.bz2

   cd eaccelerator-0.9.5.3/

   /usr/local/webserver/php/bin/phpize

   ./configure--enable-eaccelerator=shared--with-php-config=/usr/local/webserver/php/bin/php-config

   make

   make install

   make clean

   make distclean

   cd../

   tar zxvf PDO_MYSQL-1.0.2.tgz

   cd PDO_MYSQL-1.0.2/

   /usr/local/webserver/php/bin/phpize

   ./configure--with-php-config=/usr/local/webserver/php/bin/php-config--with-pdo-mysql=/usr/local/webserver/mysql

   make

   make install

   make clean

   make distclean

   cd../

   tar zxvf ImageMagick.tar.gz

   cd ImageMagick-6.5.1-2/

   ./configure

   make

   make install

   make clean

   make distclean

   cd../

   tar zxvf imagick-2.2.2.tgz

   cd imagick-2.2.2/

   /usr/local/webserver/php/bin/phpize

   ./configure--with-php-config=/usr/local/webserver/php/bin/php-config

   make

   make install

   make clean

   make distclean

   cd../

5、修改php.ini文件

STRONG手工修改:/STRONG查找/usr/local/webserver/php/etc/php.ini中的extension_dir="./"

修改为extension_dir="/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"

并在此行后增加以下几行,然后保存:

extension="memcache.so"

extension="pdo_mysql.so"

extension="imagick.so"

再查找output_buffering= Off

修改为output_buffering= On

6、配置eAccelerator加速PHP:

mkdir-p/usr/local/webserver/eaccelerator_cache

vi/usr/local/webserver/php/etc/php.ini

按shift+g键跳到配置文件的最末尾,加上以下配置信息:

复制代码

   

代码如下:

[eaccelerator]

   zend_extension="/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"

   eaccelerator.shm_size="128"

   eaccelerator.cache_dir="/usr/local/webserver/eaccelerator_cache"

   eaccelerator.enable="1"

   eaccelerator.optimizer="1"

   eaccelerator.check_mtime="1"

   eaccelerator.debug="0"

   eaccelerator.filter=""

   eaccelerator.shm_max="0"

   eaccelerator.shm_ttl="300"

   eaccelerator.shm_prune_period="120"

   eaccelerator.shm_only="0"

   eaccelerator.compress="1"

   eaccelerator.compress_level="9"

修改配置文件:

vi/etc/sysctl.conf

kernel.shmmax= 134217728

然后执行以下命令使配置生效:/sbin/sysctl-p

以下的步骤和张宴步骤中一样配置,不再赘诉

centos6.5安装wps提示缺libc.so.6(GLIBC_2.15)(64bit),怎办

1.试图运行程序,提示"libc.so.6: version `GLIBC_2.14' not found",原因是系统的glibc版本太低,软件编译时使用了较高版本的glibc引起的:

[ghui@StuOS bin]$ pwd

/var/VMdisks/cross/mingw32/bin

[ghui@StuOS bin]$ ls

lrelease QtCore4.dll QtNetwork4.dll QtSql4.dll QtXml4.dll

moc QtDeclarative4.dll QtOpenGL4.dll QtSvg4.dll rcc

phonon4.dll QtGui4.dll QtScript4.dll QtTest4.dll uic

qmake QtMultimedia4.dll QtScriptTools4.dll QtWebKit4.dll

[ghui@StuOS bin]$./qmake

./qmake:/lib64/libc.so.6: version `GLIBC_2.14' not found(required by./qmake)

2.查看系统glibc支持的版本:

[ghui@StuOS bin]$ strings/lib64/libc.so.6|grep GLIBC_

GLIBC_2.2.5

GLIBC_2.2.6

GLIBC_2.3

GLIBC_2.3.2

GLIBC_2.3.3

GLIBC_2.3.4

GLIBC_2.4

GLIBC_2.5

GLIBC_2.6

GLIBC_2.7

GLIBC_2.8

GLIBC_2.9

GLIBC_2.10

GLIBC_2.11

GLIBC_2.12

GLIBC_PRIVATE

[ghui@StuOS bin]$ rpm-qa|grep glibc

glibc-static-2.12-1.80.el6_3.6.x86_64

glibc-headers-2.12-1.80.el6_3.6.x86_64

glibc-common-2.12-1.80.el6_3.6.x86_64

glibc-devel-2.12-1.80.el6_3.6.x86_64

glibc-static-2.12-1.80.el6_3.6.i686

glibc-devel-2.12-1.80.el6_3.6.i686

glibc-2.12-1.80.el6_3.6.i686

glibc-2.12-1.80.el6_3.6.x86_64

3.可以看到最高只支持2.12版本,所以考虑编译解决这个问题:

a.到下载最新版本,我这里下载了glibc-2.14.tar.xz这个版本,解压到任意目录准备编译

b.这里解压到/var/VMdisks/glibc-2.14/

[ghui@StuOS bin]$ cd/var/VMdisks/glibc-2.14/

[ghui@StuOS glibc-2.14]$ pwd

/var/VMdisks/glibc-2.14

[ghui@StuOS glibc-2.14]$ ls

c.在glibc源码目录建立构建目录,并cd进入构建目录

[ghui@StuOS glibc-2.14]$ mkdir build

[ghui@StuOS glibc-2.14]$ cd build

d.运行configure配置,make&& sudo make install

[ghui@StuOS build]$../configure--prefix=/opt/glibc-2.14

[ghui@StuOS build]$ make-j4

[ghui@StuOS build]$ sudo make install

[sudo] password for ghui:

4.临时修改环境变量

[ghui@StuOS bin]$ export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH

[ghui@StuOS glibc-2.14]$ cd/var/VMdisks/cross/mingw32/bin/

[ghui@StuOS bin]$./qmake

Usage:./qmake [mode] [options] [files]

QMake has two modes, one mode for generating project files based on

some heuristics, and the other for generating makefiles. Normally you

shouldn't need to specify a mode, as makefile generation is the default

mode for qmake, but you may use this to test qmake on an existing project

CentOS下CronTab任务周期计划详解

CronTab任务周期计划

格式:

***** command

分(0-59)、时(0-23)、日(1-31)、月(1-12)、周(0-6)

说明:

1、星号可以匹配所有字符

2、一个整数、必须精确匹配

3、用短划线隔开的两个整数,它们匹配的是值的范围。

4、时间范围后加斜扛和一个步长值。1-10/2

普通用户流程:

crontab-e crontab是设置了setuid的,所以用户具有他的权限也就是root,并会在/tmp/cron....文件处理后保存在/var/spool/cron/$username中。

日志:

/var/log/cron

配置目录:

/var/run/crond.pid进程号地址

/etc/crontab使用指导文件

/etc/$weekday.等分别时日月周的目录,即可以把脚本放进去他会按时执行。

/etc/cron.{deny,allow}拒绝和允许用户使用crontab

Vixie-Cron:

centos安装时会默认安装此包,此包可以包括一个步长值。也就是如1,3,6,9,12可以写成,1-12/3除以3。所谓的*/1*/2也就是每一分钟每两分钟运行command。即1-59/{2,3}。

%号的运用:

%百分号表示command中的换行,只有第一个百分号之前的文本才包含在实际命令中,其余的行则作为该命令的标准输入。

安装:

yum install-y crontabs

使用:

crontab--help

crontab-e#检出一个crontab副本,调用vi编辑它,并重新保存在crontab目录。

crontab-l#将crontab的内容打印到标准输出。

crontab-r#册除并不留任何内容。

......

root册除其它用户。

crontab-r$username

[root@nagios~]# crontab--help

crontab: invalid option--'-'

crontab: usage error: unrecognized option

usage:crontab [-u user] file

crontab [-u user] [-e|-l|-r ]

(default operation is replace, per 1003.2)

-e(edit user's crontab)

-l(list user's crontab)

-r(delete user's crontab)

-i(prompt before deleting user's crontab)
