Centos7下nginx-1.12.2编辑安装与脚本安装的记录

一、安装工具及依赖

yum install -y wget make cmake gcc gcc-c++

yum install -y pcre pcre-devel lib zlib-devel  &&

openssl openssl-devel

二、下载及解压nginx

wget http://nginx.org/download/nginx-1.12.2.tar.gz &&

tar -xzvf  nginx-1.12.2.tar.gz && rm -f nginx-1.12.2.tar.gz && cd nginx-1.12.2
[root@localhost nginx-1.12.2]# pwd
/usr/local/nginx-1.12.2

三、编译安装

./configure --prefix=/usr/local/nginx &&
make && make install

四.检查安装

启动Nginx，启动完之后检查nginx是否已经正常启动

[root@localhost nginx-1.12.2]# /usr/local/nginx/sbin/nginx
[root@localhost nginx-1.12.2]# ps -ef |grep nginx
root      12563      1  0 14:44 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
nobody    12564  12563  0 14:44 ?        00:00:00 nginx: worker process

root      12568   3627  0 14:45 pts/1    00:00:00 grep --color=auto nginx

五、nginx常用命令

/usr/local/nginx/sbin/nginx -s start 启动nginx
/usr/local/nginx/sbin/nginx -s stop 关闭nginx
/usr/local/nginx/sbin/nginx -s reload 重启nginx

六、配置防火墙

[root@localhost nginx-1.12.2]# firewall-cmd --zone=public --add-port=80/tcp --permanent
success
[root@localhost nginx-1.12.2]# firewall-cmd --reload
success

七、测试nginx访问

通过浏览器访问nginx欢迎页，在地址栏输入：http://192.1680.122，如下图所示。

八、配置nginx

nginx最重要的配置文件nginx.conf

[root@localhost nginx-1.12.2]# vi /usr/local/nginx/conf/nginx.conf

#user  nobody;

#开启进程数 <=cpu数
worker_processes  1;

#错误日志保存位置
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#进程号保存文件
#pid        logs/nginx.pid;


#每个进程最大连接数（最大连接=连接数x进程数）每个worker允许同时产生多少个链接，默认1024
events {
    worker_connections  1024;
}


http {
	#文件扩展名与文件类型映射表
    include       mime.types;
	 #默认文件类型
    default_type  application/octet-stream;

	#日志文件输出格式 这个位置相于全局设置
    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

	#请求日志保存位置
    #access_log  logs/access.log  main;

	#打开发送文件
    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
	#连接超时时间
    keepalive_timeout  65;

    #打开gzip压缩
	#gzip  on;

    server {
		#监听端口
        listen       80;
        #监听域名
		server_name  localhost;

        #charset koi8-r;

        #nginx访问日志放在logs/host.access.log下，并且使用main格式（还可以自定义格式）
		#access_log  logs/host.access.log  main;
		
		#如果没有location更明确的匹配访问路径的话，访问请求都会被该location处理
        location / {
			#root指定nginx的根目录为/usr/local/nginx/html
            root   html;
			 #默认访问文件，欢迎页先去html目录下找index.html，如果找不到再去找index.htm
            index  index.html index.htm;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
		#错误页面及其返回地址，错误码为500、502、503、504都会返回50.html错误页面。
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ .php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ .php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /.ht {
        #    deny  all;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

配置文件里可以添加多个server，server监听的端口不同，可以根据需要让nginx代理多个端口，每个端口指定去做某些事情。

9、脚本安装

#!/usr/bin/env bash
echo -e 'e[31mInstallation tools and dependenciese[0m'
yum install -y wget make cmake gcc gcc-c++ && 
pcre-devel lib zlib-devel && 
openssl openssl-devel
if [ $? -eq 0 ];then
    echo -e 'e[32mSuccessful!e[0m'
else
    echo -e 'e[31mFailede[0m'
    exit 0
fi
echo -e 'e[31mInstallation nginxe[0m'
wget http://nginx.org/download/nginx-1.12.2.tar.gz && 
tar -xzvf  nginx-1.12.2.tar.gz && rm -f nginx-1.12.2.tar.gz && cd nginx-1.12.2 &&
./configure --prefix=/usr/local/nginx && 
make && make install
if [ $? -eq 0 ];then
    echo -e 'e[32mSuccessful!e[0m'
else
    echo -e 'e[31mFailede[0m'
    exit 0
fi
echo -e 'e[31mStart nginxe[0m'
/usr/local/nginx/sbin/nginx
echo -e 'e[32mSuccessful!e[0m'

亲测成功！主要防火墙开放80端口！
