linux下nginx安装
nginx安装
可以用root安装，也可以用其他用户sudo安装，还是用root安装简单
需要先装gcc，我的已经安了，
[oracle@dev Server]$ rpm -q gcc
gcc-4.1.2-51.el5
?
prce也安了，不是最新的
[oracle@dev sbin]$ rpm -q pcre
pcre-6.6-6.el5_6.1
?
安装pcre （让nginx支持rewrite）
下载最新PCRE（Perl Compatible Regular Expressions）源码包
http://www.pcre.org/
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.21.tar.gz
?
使用下面命令下载编译和安装 PCRE 包：
# wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.21.tar.gz?下载
# tar zxvf pcre-8.21.tar.gz
# cd pcre-8.21
# ./configure
# make
# sudo make install
?
安装nginx
下载地址
http://nginx.org/en/download.html
[oracle@dev opt]tar zxvf nginx-1.3.12.tar.gz
[oracle@dev opt] cd nginx-1.3.12
[oracle@dev nginx-1.3.12]$ ./configure --with-http_stub_status_module
[oracle@dev nginx-1.3.12]$ make install
[oracle@dev nginx-1.3.12]$ sudo make install
?
启动nginx
oracle@dev nginx-1.3.12]$ cd /usr/local/nginx/sbin
[oracle@dev sbin]$ sudo ./nginx &
[2] 16121
要是出现如下信息说明端口被占用了，我的是被weblogic占用了，可先停止webloigc，或修改weblogic端口
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
?
访问地址
http://localhost/
?
停止nginx
[oracle@dev sbin]$ sudo ./nginx -s stop
或
[oracle@dev sbin]$ sudo ./nginx -s quit
?
Nginx -s stop???????? 快速关闭Nginx，可能不保存相关信息，并迅速终止web服务。（quick exit）
Nginx -s quit???????? 平稳关闭Nginx，保存相关信息，有安排的结束web服务。（graceful exit）
Nginx -s reload?????? 因改变了Nginx相关配置，需要重新加载配置而重载。（changing configuration，start a new worker,quitting an old worker gracefully.)
Nginx -s reopen?????? 重新打开日志文件。(reopenging log files)
?
