tony_nginx的安装和配置

yum安装nginx

Centos默认的yum源里没有nginx，需要手动添加源，有两种方法：

使用nginx提供的一个源设置安装包

nginx下载页面：http://nginx.org/en/download.html

nginx提供4个版本的系统的源：

• RHEL 5
• RHEL 6
• CentOS 5
• CentOS 6

我选择Centos6，文件名为：nginx-release-centos-6-0.el6.ngx.noarch.rpm。

在服务器上安装：

rpm -ivh nginx-release-centos-6-0.el6.ngx.noarch.rpm

之后便可以使用yum快速安装了：

yum install nginx

手动添加nginx源

cd /etc/yum.repos.d

vim nginx.repo

#内容为：

[nginx]

name=nginx repo

baseurl=http://nginx.org/packages/centos/6/$basearch/

gpgcheck=

enabled=

baseurl中centos和6可以更改为自己的版本，比如redhat 5版本的链接为：

baseurl=http://nginx.org/packages/rhel/5/$basearch/

详情可以自己看nginx的下载页面，包括其他系统的源安装方法。

相关路径

nginx可执行文件：/usr/sbin/nginx

nginx配置目录：/etc/nginx

nginx log目录：/var/log/nginx

编译安装nginx

我的nginx编译安装代码：

yum install perl-ExtUtils-Embed.x86_64 pcre-devel.x86_64

#根据自己的需求，选择参数，可用的参数可以使用./configure --help命令查看

./configure --prefix=/opt/nginx

                 --with-http_gzip_static_module

                 --with-http_perl_module

                 --with-pcre

                 --with- rtsig_module

                 --with-select_module

                 --with-poll_module

                 --with-file-aio

make

make install

为编译安装的nginx配置init脚本：

vim /etc/init.d/nginx

#内容取自yum安装的nginx后，生成的文件，改下里面的路径即可使用了

#!/bin/sh

#

# nginx        Startup script for nginx

#

# chkconfig: -

# processname: nginx

# config: /opt/nginx/conf/nginx.conf

# config: /etc/sysconfig/nginx

# pidfile: /opt/nginx/logs/nginx.pid

# description: nginx is a HTTP and reverse proxy server

使用chkconfig安装为安装启动项

chkconfig --add nginx

chkconfig nginx on

nginx命令:
启动：nginx
停止：nginx -s stop
重置生效：nginx -s reload
