[操作系统]安装Nginx服务


Nginx最大特点:

静态小文件(1M),支持高并发,同时占用系统资源很少。3W并发,10个进程,内存150M。

Nginx特点:

1、配置简单,灵活,轻量。

2、高并发(静态小文件),静态几万的并发。

3、占用资源少。2W并发 开10个线程服务,内存消耗几百M。

4、功能种类较多(Web,cache,proxy),每一个功能都不是特别强。

5、支持epoll模型,使得Nginx可以支持高并发!apache(select模型)。

6、Nginx可以配合动态服务(FASTCGI接口)

7、利用nginx可以对IP限速,可以限制连接数。

1.1 Nginx安装

1.1.1 创建Nginx虚拟用户

 

1 [root@Web-lnmp02 ~]# useradd nginx -s /sbin/nologin -M  ##禁止用户用于ssh登录,且不创建家目录2 [root@Web-lnmp02 ~]# id nginx3 uid=501(nginx) gid=501(nginx) groups=501(nginx)4 [root@Web-lnmp02 ~]# 

 

1.1.2 在安装Nginx之前安装配套的pcre

 1 [root@Web-lnmp02 tools]# rpm -qa pcre pcre-devel          2 pcre-7.8-7.el6.x86_64 3 [root@Web-lnmp02 tools]# yum install -y pcre pcre-devel 4 Loaded plugins: fastestmirror, security 5 Setting up Install Process 6 Loading mirror speeds from cached hostfile 7 * base: mirrors.sina.cn 8 * extras: mirrors.opencas.cn 9 * updates: centos.ustc.edu.cn10 Package pcre-7.8-7.el6.x86_64 already installed and latest version11 Resolving Dependencies12 --> Running transaction check13 ---> Package pcre-devel.x86_64 0:7.8-7.el6 will be installed14 --> Finished Dependency Resolution15 16 Dependencies Resolved17 18 ================================================================================19  Package       Arch       Version       Repository   Size20 ================================================================================21 Installing:22 pcre-devel      x86_64      7.8-7.el6      base      320 k23 24 Transaction Summary25 ================================================================================26 Install    1 Package(s)27 28 Total download size: 320 k29 Installed size: 957 k30 Downloading Packages:31 pcre-devel-7.8-7.el6.x86_64.rpm             | 320 kB   00:00   32 Running rpm_check_debug33 Running Transaction Test34 Transaction Test Succeeded35 Running Transaction36  Installing : pcre-devel-7.8-7.el6.x86_64                 1/1 37  Verifying : pcre-devel-7.8-7.el6.x86_64                 1/1 38 39 Installed:40  pcre-devel.x86_64 0:7.8-7.el6                       41 [root@Web-lnmp02 tools]# rpm -qa pcre pcre-devel   42 pcre-7.8-7.el6.x86_6443 pcre-devel-7.8-7.el6.x86_64

1.1.3  安装SSL Modules跟OpenSSL library

 

1 [root@Web-lnmp02 ~]# yum install -y openssl-devel2 [root@Web-lnmp02 ~]# rpm -qa|grep openssl    3 openssl-1.0.1e-42.el6_7.2.x86_644 openssl-devel-1.0.1e-42.el6_7.2.x86_645 openssl098e-0.9.8e-18.el6_5.2.x86_64

 

1.1.4 下载Nginx,并且编译安装

 

 1 [root@Web-lnmp02 tools]# wget http://nginx.org/download/nginx-1.6.3.tar.gz 2 --2015-11-28 20:50:36-- http://nginx.org/download/nginx-1.6.3.tar.gz 3  4 [root@Web-lnmp02 tools]# ll 5 total 788 6 -rw-r--r--. 1 root root 805253 Apr 8 2015 nginx-1.6.3.tar.gz 7 [root@Web-lnmp02 tools]# tar xf nginx-1.6.3.tar.gz ##解压 8 [root@Web-lnmp02 tools]# ll 9 total 79210 drwxr-xr-x. 8 1001 1001  4096 Apr 7 2015 nginx-1.6.311 -rw-r--r--. 1 root root 805253 Apr 8 2015 nginx-1.6.3.tar.gz12 [root@Web-lnmp02 tools]# 

 

编译安装Nginx

 

 1 [root@Web-lnmp02 tools]# cd nginx-1.6.3 2 [root@Web-lnmp02 nginx-1.6.3]# ls -lk 3 total 624 4 drwxr-xr-x. 6 1001 1001  4 Nov 28 20:52 auto 5 -rw-r--r--. 1 1001 1001 232 Apr 7 2015 CHANGES 6 -rw-r--r--. 1 1001 1001 353 Apr 7 2015 CHANGES.ru 7 drwxr-xr-x. 2 1001 1001  4 Nov 28 20:52 conf 8 -rwxr-xr-x. 1 1001 1001  3 Apr 7 2015 configure 9 drwxr-xr-x. 4 1001 1001  4 Nov 28 20:52 contrib10 drwxr-xr-x. 2 1001 1001  4 Nov 28 20:52 html11 -rw-r--r--. 1 1001 1001  2 Apr 7 2015 LICENSE12 drwxr-xr-x. 2 1001 1001  4 Nov 28 20:52 man13 -rw-r--r--. 1 1001 1001  1 Apr 7 2015 README14 drwxr-xr-x. 8 1001 1001  4 Nov 28 20:52 src15 [root@Web-lnmp02 nginx-1.6.3]# ./configure --prefix=/application/nginx-1.6.3 --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_module16 [root@Web-lnmp02 nginx-1.6.3]# make && make install ##编译

 

备注:

参数简单说明:

--prefix=PATH   设置安装路径

--user=USER      进程用户权限

--group=GROUP  进程用户组权限

--with-http_ssl_module   激活ssl功能

--with-http_stub_status_module  激活状态信息

 

接着创建软链接:

 

 1 [root@Web-lnmp02 nginx-1.6.3]# ln -s /application/nginx-1.6.3/ /application/nginx 2 [root@Web-lnmp02 nginx-1.6.3]# ls -l /application/ 3 total 4 4 lrwxrwxrwx. 1 root root  25 Nov 28 21:18 nginx -> /application/nginx-1.6.3/ 5 drwxr-xr-x. 6 root root 4096 Nov 28 21:09 nginx-1.6.3 6 [root@Web-lnmp02 nginx-1.6.3]# cd nginx 7 -bash: cd: nginx: No such file or directory 8 [root@Web-lnmp02 nginx-1.6.3]# cd /application/nginx 9 [root@Web-lnmp02 nginx]# ll10 total 1611 drwxr-xr-x. 2 root root 4096 Nov 28 21:09 conf12 drwxr-xr-x. 2 root root 4096 Nov 28 21:09 html13 drwxr-xr-x. 2 root root 4096 Nov 28 21:09 logs14 drwxr-xr-x. 2 root root 4096 Nov 28 21:09 sbin

 

1.1.5 启动Nginx服务

 

 

 

1 [root@Web-lnmp02 nginx]# /application/nginx/sbin/nginx  ##启动Nginx服务2 [root@Web-lnmp02 nginx]# lsof -i :803 COMMAND PID USER  FD  TYPE DEVICE SIZE/OFF NODE NAME4 nginx  5027 root  6u IPv4 23623   0t0 TCP *:http (LISTEN)5 nginx  5028 nginx  6u IPv4 23623   0t0 TCP *:http (LISTEN)6 [root@Web-lnmp02 nginx]# netstat -lntup|grep nginx|grep -v grep7 tcp    0   0 0.0.0.0:80         0.0.0.0:*          LISTEN   5027/nginx
