linux 下安裝nginx

1)下載nginx

wget  http://nginx.org/download/nginx-0.8.54.tar.gz

wget  http://nginx.org/download/nginx-0.8.54.tar.gz

默認會下載到當前目錄下面，也就是pwd目錄

2)解壓

tar zxvf nginx-0.8.54.tar.gz

tar zxvf nginx-0.8.54.tar.gz

進入nginx目錄  cd nginx-0.8.54
3)

./configure

./configure 

configure這一步可能會出現，找不到pcre的error
那麼如果可以連網建議用yum命令去安裝依賴包。

yum -y install gcc pcre-devel openssl openssl-devel

yum -y install gcc pcre-devel openssl openssl-devel

如果沒有網絡，可到CentOS 5.5 DVD下找如下包，按順序安裝

rpm -ivh pcre-devel-6.6-2.el5_1.7.i386.rpm
rpm -ivh openssl-0.9.8e-12.el5_4.6.i386.rpm
rpm -ivh e2fsprogs-devel-1.39-23.el5.i386.rpm
rpm -ivh keyutils-libs-devel-1.2-1.el5.i386.rpm
rpm -ivh libsepol-devel-1.15.2-3.el5.i386.rpm
rpm -ivh libselinux-devel-1.33.4-5.5.el5.i386.rpm
rpm -ivh krb5-devel-1.6.1-36.el5_4.1.i386.rpm
rpm -ivh zlib-devel-1.2.3-3.i386.rpm
rpm -ivh openssl-devel-0.9.8e-12.el5_4.6.i386.rpm

rpm -ivh pcre-devel-6.6-2.el5_1.7.i386.rpm
rpm -ivh openssl-0.9.8e-12.el5_4.6.i386.rpm 
rpm -ivh e2fsprogs-devel-1.39-23.el5.i386.rpm 
rpm -ivh keyutils-libs-devel-1.2-1.el5.i386.rpm
rpm -ivh libsepol-devel-1.15.2-3.el5.i386.rpm
rpm -ivh libselinux-devel-1.33.4-5.5.el5.i386.rpm
rpm -ivh krb5-devel-1.6.1-36.el5_4.1.i386.rpm
rpm -ivh zlib-devel-1.2.3-3.i386.rpm
rpm -ivh openssl-devel-0.9.8e-12.el5_4.6.i386.rpm

安裝好後再執行 ./configure
最後會看到類似下面信息，表示編譯成功

Configuration summary
  + using system PCRE library
  + OpenSSL library is not used
  + md5: using system crypto library
  + sha1 library is not used
  + using system zlib library

4)

make

make 

5)

make install

make install

默認會安裝到

/usr/local/nginx

/usr/local/nginx

目錄下面

6) 啓動

/usr/local/nginx/sbin/nginx

/usr/local/nginx/sbin/nginx

查看是否啓動成功

[root@maomao sbin]# ps aux | grep nginx
root     10391  0.0  0.0   4008   456 ?        Ss   10:48   0:00 nginx: [b][color=red]master[/color][/b] process ./nginx
nobody   10392  0.0  0.0   4164   796 ?        S    10:48   0:00 nginx: worker process

[root@maomao sbin]# ps aux | grep nginx
root     10391  0.0  0.0   4008   456 ?        Ss   10:48   0:00 nginx: [b][color=red]master[/color][/b] process ./nginx
nobody   10392  0.0  0.0   4164   796 ?        S    10:48   0:00 nginx: worker process

啓動成功，master是主進程，關閉的時候kill這個進程，其他子進程會自動關掉

打開瀏覽器http://localhost/ 即可看到nginx的默認歡迎頁
Welcome to nginx!

nginx默認是用80端口，我們可以在nginx安裝目錄下的conf/nginx.conf文件中更改。

vim /usr/local/nginx/conf/nginx.conf

vim /usr/local/nginx/conf/nginx.conf

找到以下片段進行更改，然後重啓

server {
       listen       80; //端口
       server_name  localhost; //綁定域名
       location / {
           root   html; //默認目錄
           index  index.html index.htm; //默認首頁名稱
       }
}

 server {
        listen       80; //端口
        server_name  localhost; //綁定域名
        location / {
            root   html; //默認目錄
            index  index.html index.htm; //默認首頁名稱
        }
 }

更改好後，重啓nginx。

kill -HUP `cat /usr/local/nginx/logs/nginx.pid`

kill -HUP `cat /usr/local/nginx/logs/nginx.pid`

HUP信號是平滑重啓

停止nginx

kill  `cat /usr/local/nginx/logs/nginx.pid`
