如何在CentOS 6使用yum安装nginx

Answer 1

开始安装Nginx和PHP-FPM之前,你必须卸载系统中以前安装的Apache和PHP。用root登录输入下面的命令：
[plain] view plain copy
# yum remove httpd* php*

增加额外资源库

默认情况下，CentOS的官方资源是没有php-fpm的, 但我们可以从Remi的RPM资源中获得，它依赖于EPEL资源。我们可以这样增加两个资源库：

[plain] view plain copy
# yum install yum-priorities -y
# rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-7.noarch.rpm
# rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

输出样例

[plain] view plain copy
Retrieving http://download.fedora.redhat.com/pub/epel/6/x86_64/epel-release-6-7.noarch.rpm

安装Nginx

输入下列命令

[plain] view plain copy
# yum install nginx

Answer 2

一、更改yum源为网易的源加快速度

vi /etc/yum.repos.d/CentOS-Base.repo
更改内容如下

# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the

# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
#

[base]
name=CentOS-$releasever - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/

gpgcheck=1

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

二、update yum

yum -y update

三、利用CentOS Linux系统自带的yum命令安装、升级所需的程序库

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

四、安装php和mysql

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

五、安装nginx
由于centos没有默认的nginx软件包，需要启用REHL的附件包

rpm -Uvh http://download.Fedora.RedHat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm
yum -y install nginx

设置开机启动

chkconfig nginx on

六、安装spawn-fcgi来运行php-cgi

yum install spawn-fcgi

七、下载spawn-fcgi 的启动脚本

wget http://bash.cyberciti.biz/dl/419.sh.zip
unzip 419.sh.zip
mv 419.sh /etc/init.d/php_cgi
chmod +x /etc/init.d/php_cgi

启动php_cgi

/etc/init.d/php_cgi start

查看进程

netstat -tulpn | grep :9000

若出现如下代表一切正常

tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 4352/php-cgi

八、配置nginx(详细配置见nginx.conf详细说明)

location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html$fastcgi_script_name;
include fastcgi_params;
}

九、查看phpinfo
编写脚本

phpinfo();

十、安装phpmyadmin
修改/var/lib/php/session的权限和nginx和php_cgi一致

chown -R www.www /var/lib/php/session
