nginx是本身就可以實現靜態資源的web服務
1、檢查安裝nginx的依賴性，nginx的模塊需要第三方庫的支持，檢查是否安裝下列庫：
zlib、zlib-devel、openssl、openssl-devel、prce、prce-devel
[root@mgmserver ~]# rpm -qa |grep zlib
zlib-devel-1.2.3-3
zlib-1.2.3-3
[root@mgmserver tar_packet]# rpm -qa |grep openssl
openssl-0.9.8e-12.el5
openssl-devel-0.9.8e-12.el5
[root@mgmserver tar_packet]# rpm -qa |grep pcre
pcre-6.6-2.el5_1.7
pcre-devel-6.6-2.el5_1.7
[root@mgmserver tar_packet]# rpm -qa |grep gcc
compat-libgcc-296-2.96-138
compat-gcc-34-g77-3.4.6-4
gcc-c++-4.1.2-46.el5
libgcc-4.1.2-46.el5
compat-gcc-34-3.4.6-4
compat-gcc-34-c++-3.4.6-4
gcc-java-4.1.2-46.el5
gcc-4.1.2-46.el5
gccp-gfortran-4.1.2-46.el5
[root@mgmserver tar_packet]# rpm -qa |grep autoconf
autoconf-2.59-12
[root@mgmserver tar_packet]# rpm -qa |grep automake
automake-1.9.6-2.1
automake16-1.6.3-8
automake15-1.5-16
automake17-1.7.9-7
automake14-1.4p6-13
2、添加nginx使用的用戶和組 ，
[root@mgmserver ~]# groupadd nginx #nginx使用的組；
[root@mgmserver ~]# useradd -g nginx nginx #nginx使用用戶；
3、安裝
[root@mgmserver ~]# cd /home/tar_packet/
[root@mgmserver tar_packet]# tar -zxvf nginx-0.8.48.tar.gz -C /home/install_packet/
[root@mgmserver tar_packet]# cd ../install_packet/
[root@mgmserver install_packet]# cd nginx-0.8.48/
[root@mgmserver nginx-0.8.48]# ls
auto CHANGES CHANGES.ru conf configure contrib html LICENSE README src
[root@mgmserver nginx-0.8.48]# ./configure --prefix=/usr/local/nginx \
> --user=nginx \
> --group=nginx \
> --with-http_stub_status_module \ #啓用“server status"頁
> --with-http_ssl_module #開啓http ssl模塊，使nginx可以支持https請求，這個模塊需要已經

[root@mgmserver nginx-0.8.48]#make
[root@mgmserver nginx-0.8.48]#make install
二、啓動nginx
[root@mgmserver nginx]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
參數"-c"指定了配置文件的路徑，如果不加'-c"參數， nginx，會默認加載其安裝目錄中conf子目錄中的nginx.conf文件。
[root@mgmserver nginx-0.8.48]# ps -ef |grep nginx
可以看到一個主nginx的進程信息，一個子進程；如果在安裝過程指定了“-pid-path=<path>那麼該文件就指定了nginx的主進程號，如果沒有指定pid文件的存放路徑，nginx.pid默認存放在nginx安裝目錄的logs子目錄下，
[root@mgmserver logs]# ls
access.log error.log nginx.pid
[root@mgmserver logs]# cat nginx.pid
6019
三、nginx的信號控制
TERM,INT 快速關閉
QUIT 從容關閉
HUP 平滑重啓，重新加載配置文件
USR1 重新打開日誌文件，在切割日誌時用途較大；
USR2 平滑升級可執行程序
WINCH 從容關閉工作進程
我們可以直接通過以下命令來完成平滑重啓，省下尋找nginx主進程號的步驟；
kill -"信號類型” ‘/usr/local/nginx/logs/nginx.pid'或者nginx的主進程號
(1）、從容停止nginx
[root@mgmserver ~]# kill -QUIT 6019 #nginx主進程號
[root@mgmserver logs]# kill -QUIT `cat /usr/local/nginx/logs/nginx.pid`
(2)、快速停止nginx
[root@mgmserver logs]# kill -TERM /INT nginx主進程號
[root@mgmserver logs]# kill -TERM /INT `cat
/usr/local/nginx/logs/nginx.pid
(3)、強制停止所有的nginx進程
#pkill -9 nginx
(4)、平滑重啓nginx
修改了nginx的配置文件要重啓nginx；重啓之前要檢查配置文件是否正確：
[root@mgmserver html]# /usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@mgmserver conf]# kill -HUP `cat /usr/local/nginx/logs/nginx.pid`
注意符號；
nginx的平滑重啓
kill -HUP Nginx主進程號
或者
kill -HUP ·nginx.pid文件按存放路徑·
