centos下安装nginx


[root@iZ258gu0zkwZ tmp]# wget http://nginx.org/download/nginx-1.9.4.tar.gz
[root@iZ258gu0zkwZ tmp]# tar zxvf nginx-1.9.4.tar.gz 
[root@iZ258gu0zkwZ tmp]# cd nginx-1.9.4
[root@iZ258gu0zkwZ nginx-1.9.4]# ./configure --prefix=/opt/nginx --with-http_stub_status_module
出错：
./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.


安装pcre，可提示已是最新版本：
[root@iZ258gu0zkwZ nginx-1.9.4]# yum install pcre
Loaded plugins: security

现在是需要1.7.11以上的支持多线程模型的nginx版本，直接用yum查看nginx版本是0.8几，如下处理：
[root@iZ258gu0zkwZ nginx-1.9.4]# rpm -ivh http://nginx.org/packages/centos/5/i386/RPMS/nginx-1.8.0-1.el5.ngx.i386.rpm

重新安装，好像版本就对了：
[root@iZ258gu0zkwZ nginx-1.9.4]# whereis nginx
nginx: /usr/sbin/nginx /etc/nginx /usr/share/nginx
[root@iZ258gu0zkwZ nginx-1.9.4]# nginx -v
nginx version: nginx/1.8.0




修改nginx.conf文件，增加uwsgi的支持：
     31     server {
     32         listen       80;
     33         server_name  localhost;
     34 
     35         #charset koi8-r;

     37         #access_log  logs/host.access.log  main;

     39         location / {
     40             #root   html;
     41             #index  index.html index.htm;
     42             #aio threads;
     43             include uwsgi_params;

************************************************************************************************************************************************************************************************************************************
编译安装nginx
************************************************************************************************************************************************************************************************************************************
[root@iZ258gu0zkwZ vpoker]# nginx -s reload
nginx: [emerg] "aio threads" is unsupported on this platform in /etc/nginx/nginx.conf:42
不支持多线程模式，而现在需要用到这个特性，不确定到底是不是系统问题，重新带参数编译一下nginx


[root@iZ258gu0zkwZ tmp]# wget http://nginx.org/download/nginx.1.9.4.tar.g
[root@iZ258gu0zkwZ tmp]# tar zxvf nginx-1.9.4.tar.gz
[root@iZ258gu0zkwZ tmp]# cd nginx-1.9.4


[root@iZ258gu0zkwZ nginx-1.9.4]# ./configure --prefix=/usr/local/nginx --with-threads --with-http_stub_status_module
出错：
./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.


解决：
[root@iZ258gu0zkwZ nginx-1.9.4]# yum -y install pcre-devel


再次执行./configure，成功：

编译安装：
make
make install


[root@iZ258gu0zkwZ nginx-1.9.4]# cd /usr/local/nginx/sbin
[root@iZ258gu0zkwZ sbin]# ./nginx -v

configure arguments: --prefix=/usr/local/nginx --with-threads --with-http_stub_status_module


这次在nginx.conf中增加aio threads，重新加载没有出错！




nginx配置状态，修改nginx.conf文件：
     54         location /nginx_status
     55         {
     56                 stub_status on;
     57                 access_log off;
     58                 #allow 127.0.0.1;
     59                 #deny all;
     60         }
 
 通过浏览器访问http://youip/nginx_status进行查看，如下：
 Active connections: 2 
server accepts handled requests
 28 28 38 
Reading: 0 Writing: 1 Waiting: 1 


还可以用如下方式查看：
[root@iZ258gu0zkwZ sbin]# netstat -n | awk '/^tcp/ {++S[$NF]} END {for(a in S) print a, S[a]}'
ESTABLISHED 57
TIME_WAIT 4

碰到这问题的时候一定要仔细看，一定是模块名字写错了！！！
