安装和使用nginx

1下载 
pcre-8.10.tar.gz
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/ 
nginx-1.1.1.tar.gz
http://nginx.org/
2安装 pcre 让nginx支持rewrite

[root@localhost pcre-8.33]# ./configure 
[root@localhost pcre-8.33]# make
[root@localhost pcre-8.33]# make install 

默认是不会编译进Nginx的,如果你要使用该模块,则要在编译安装Nginx时指定:

[root@localhost nginx-1.6.1]#  ./configure --prefix=/usr/local/nginx --with-http_stub_status_module
[root@localhost nginx-1.6.1]# make
[root@localhost nginx-1.6.1]# make install

默认安装的路径是/usr/local/nginx

更多的安装配置
./configure --prefix=/usr/local/nginx
--with-openssl=/usr/include (启用ssl)
--with-pcre=/usr/include/pcre/ (启用正规表达式)
--with-http_stub_status_module (安装可以查看nginx状态的程序)
--with-http_memcached_module (启用memcache缓存)
--with-http_rewrite_module (启用支持url重写)


3 检查是否安装成功

[root@localhost ~]# cd  /usr/local/nginx/sbin
[root@localhost sbin]# ./nginx -t

错误提示：
./nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory
解决方案：

[root@localhost sbin]# whereis libpcre.so.1
libpcre.so: /lib/libpcre.so.0 /usr/local/lib/libpcre.so.1 /usr/local/lib/libpcre.so
[root@localhost sbin]# ldd /usr/local/nginx/sbin/nginx
        linux-gate.so.1 =>  (0x00e10000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x00bbd000)
        libcrypt.so.1 => /lib/libcrypt.so.1 (0x04133000)
        libpcre.so.1 => not found
        libcrypto.so.6 => /lib/libcrypto.so.6 (0x00206000)
        libz.so.1 => /usr/lib/libz.so.1 (0x00bd6000)
        libc.so.6 => /lib/libc.so.6 (0x00a49000)
        /lib/ld-linux.so.2 (0x00a26000)
        libdl.so.2 => /lib/libdl.so.2 (0x00bb7000)
[root@localhost sbin]# ln -s /lib/libpcre.so.0.0.1 /lib/libpcre.so.1 

成功提示：
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

4启动nginx 
cd  /usr/local/nginx/sbin 目录下面 输入 ./nginx 启动 nginx
5检查是否启动成功
ie 浏览器中输入 http://192.168.15.132


6重启
/usr/local/nginx/sbin/nginx -s reload



6关闭nginxkillall -s HUP nginx 

7配置nginx_status模块监控nginx

location /nginx_status {
   stub_status on;
   access_log off;
   allow 192.168.31.1;
   deny all;
}

8nginx tomcat集群配置

vi /usr/local/nginx/conf/nginx.conf
upstream mysrv {
   #weigth参数表示权值，权值越高被分配到的几率越大 
   #ip_hash;
   server 127.0.0.1:11080 weight=1;
   server 127.0.0.1:11081 weight=1;
   server 127.0.0.1:11082 weight=1;
}

location / {
   root   html;
   index  index.html index.htm;
   proxy_pass http://mysrv/;  
}
