支持-t 检查语法错误
[root@aminglinux-02 nginx-1.12.1]# /usr/local/nginx/sbin/nginx -tnginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is oknginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
给Nginx创建启动脚本
vim /etc/init.d/nginx
启动脚本内容如下：
#!/bin/bash# chkconfig: - 30 21# description: http service.# Source Function Library. /etc/init.d/functions# Nginx SettingsNGINX_SBIN="/usr/local/nginx/sbin/nginx"NGINX_CONF="/usr/local/nginx/conf/nginx.conf"NGINX_PID="/usr/local/nginx/logs/nginx.pid"RETVAL=0prog="Nginx"start(){echo -n $"Starting $prog: "mkdir -p /dev/shm/nginx_tempdaemon $NGINX_SBIN -c $NGINX_CONFRETVAL=$?echoreturn $RETVAL}stop(){echo -n $"Stopping $prog: "killproc -p $NGINX_PID $NGINX_SBIN -TERMrm -rf /dev/shm/nginx_tempRETVAL=$?echoreturn $RETVAL}reload(){echo -n $"Reloading $prog: "killproc -p $NGINX_PID $NGINX_SBIN -HUPRETVAL=$?echoreturn $RETVAL}restart(){stopstart}configtest(){$NGINX_SBIN -c $NGINX_CONF -treturn 0}case "$1" instart)start;;stop)stop;;reload)reload;;restart)restart;;configtest)configtest;;*)echo $"Usage: $0 {start|stop|reload|restart|configtest}"RETVAL=1esacexit $RETVAL 更改配置文件权限
[root@aminglinux-02 nginx-1.12.1]# chmod 755 !$chmod 755 /etc/init.d/nginx
将nginx加入到服务列表里
chkconfig --add nginx
配置开启启动nginx服务
chkconfig nginx on
定义配置文件 默认conf目录下是有一个配置文件的，但是我们用自己的配置
[root@aminglinux-02 conf]# lsfastcgi.conf fastcgi_params.default mime.types nginx.conf.default uwsgi_paramsfastcgi.conf.default koi-utf mime.types.default scgi_params uwsgi_params.defaultfastcgi_params koi-win nginx.conf scgi_params.default win-utf[root@aminglinux-02 conf]# mv nginx.conf nginx.conf.old[root@aminglinux-02 conf]# lsfastcgi.conf fastcgi_params.default mime.types nginx.conf.old uwsgi_paramsfastcgi.conf.default koi-utf mime.types.default scgi_params uwsgi_params.defaultfastcgi_params koi-win nginx.conf.default scgi_params.default win-utf
创建一个配置文件
[root@aminglinux-02 conf]# vim nginx.conf
配置内容如下
user nobody nobody; // 定义启动nginx的用户worker_processes 2; //定义子进程有几个error_log /usr/local/nginx/logs/nginx_error.log crit; //错误日志pid /usr/local/nginx/logs/nginx.pid; // PID所在worker_rlimit_nofile 51200; //nginx最多可以打开文件的上限events{use epoll; //使用epoll模式worker_connections 6000; // 进行的最大连接数}http{include mime.types;default_type application/octet-stream;server_names_hash_bucket_size 3526;server_names_hash_max_size 4096;log_format combined_realip '$remote_addr $http_x_forwarded_for [$time_local]'' $host "$request_uri" $status'' "$http_referer" "$http_user_agent"';sendfile on;tcp_nopush on;keepalive_timeout 30;client_header_timeout 3m;client_body_timeout 3m;send_timeout 3m;connection_pool_size 256;client_header_buffer_size 1k;large_client_header_buffers 8 4k;request_pool_size 4k;output_buffers 4 32k;postpone_output 1460;client_max_body_size 10m;client_body_buffer_size 256k;client_body_temp_path /usr/local/nginx/client_body_temp;proxy_temp_path /usr/local/nginx/proxy_temp;fastcgi_temp_path /usr/local/nginx/fastcgi_temp;fastcgi_intercept_errors on;tcp_nodelay on;gzip on;gzip_min_length 1k;gzip_buffers 4 8k;gzip_comp_level 5;gzip_http_version 1.1;gzip_types text/plain application/x-javascript text/css text/htmapplication/xml;server //一个server 对应一个虚拟主机，定义这个，才能正常访问网站 下面一整段，就是一个默认的虚拟主机{listen 80;server_name localhost; //网站域名index index.html index.htm index.php;root /usr/local/nginx/html; //网站的根目录location ~ \.php$ //配置解析php的部分{include fastcgi_params;fastcgi_pass unix:/tmp/php-fcgi.sock; //nginx通过这一行配置来调用php-fpm服务fastcgi_pass 127.0.0.1：9000; //如果php-fpm监听的是9000端口，直接这样写配置即可fastcgi_index index.php;fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;}}} 作为一个网站的服务，必须监听一个端口，默认监听的是80端口，假如没有配置 server 这个几行，那么nginx将识别不到监听端口，导致服务不可用
编译好配置，就使用 -t 检查一下是否有错[root@aminglinux-02 conf]# /usr/local/nginx/sbin/nginx -tnginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok // /usr/local/nginx/conf/nginx. nginx:配置文件配置语法好nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful // /usr/local/nginx/conf/nginx. nginx:配置文件配置测试是成功的
启动服务
[root@aminglinux-02 nginx]# service nginx startStarting nginx (via systemctl): Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details. [失败]
提示出错
之后尝试执行提示的命令 “systemctl status nginx.service ”[root@aminglinux-02 111]# systemctl status nginx.service● nginx.service - SYSV: http service.

提示端口已经被占用
查看端口[root@aminglinux-02 111]# netstat -lntpActive Internet connections (only servers)Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program nametcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 4849/nginx: mastertcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1236/sshdtcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 2076/mastertcp6 0 0 :::3306 :::* LISTEN 1691/mysqldtcp6 0 0 :::22 :::* LISTEN 1236/sshdtcp6 0 0 ::1:25 :::* LISTEN 2076/master
发现占用端口的就是nginx本身
只能“杀掉 ”nginx程序再试root@aminglinux-02 111]# killall nginx[root@aminglinux-02 111]# /etc/init.d/nginx startStarting nginx (via systemctl): Warning: nginx.service changed on disk. Run 'systemctl daemon-reload' to reload units. [ 确定 ][root@aminglinux-02 111]# ps aux |grep nginxroot 6623 0.0 0.0 20484 624 ?

这时发现启动成功了
但是有警告提示 再次执行提示的命令“systemctl daemon-reload ”[root@aminglinux-02 111]# systemctl daemon-reload[root@aminglinux-02 111]# service nginx stopStopping nginx (via systemctl): [ 确定 ][root@aminglinux-02 111]# service nginx startStarting nginx (via systemctl): [ 确定 ][root@aminglinux-02 111]#
这下就正常了
启动完成以后看一下进程
[root@aminglinux-02 111]# ps aux |grep nginxroot 6762 0.0 0.0 20484 624 ?

测试一下访问情况
[root@aminglinux-02 ~]# curl localhostWelcome to nginx! Welcome to nginx!
If you see this page, the nginx web server is successfully installed andworking. Further configuration is required.
For online documentation and support please refer tonginx.org.
Commercial support is available atnginx.com.Thank you for using nginx.
测试一下是否支持PHP解析
[root@aminglinux-02 ~]# curl localhost/1.phpThis is nginx test page.[root@aminglinux-02 ~]#[root@aminglinux-02 ~]# vim /usr/local/nginx/html/1.php[root@aminglinux-02 ~]# curl -x127.0.0.1:80 localhost/1.php -IHTTP/1.1 200 OKServer: nginx/1.12.1Date: Thu, 10 Aug 2017 16:15:02 GMTContent-Type: text/html; charset=UTF-8Connection: keep-aliveX-Powered-By: PHP/5.6.30
返回码是200 证明是通的
12.7 默认虚拟主机
修改nginx.cnf配置，删除默认的虚拟主机配置，重新定义虚拟主机配置所在路径
[root@aminglinux-02 default]#vim /usr/local/nginx/conf/nginx.confuser nobody nobody;worker_processes 2;error_log /usr/local/nginx/logs/nginx_error.log crit;pid /usr/local/nginx/logs/nginx.pid;worker_rlimit_nofile 51200;events{ use epoll; worker_connections 6000;}http{ include mime.types; default_type application/octet-stream; server_names_hash_bucket_size 3526; server_names_hash_max_size 4096; log_format combined_realip '$remote_addr $http_x_forwarded_for [$time_local]' ' $host "$request_uri" $status' ' "$http_referer" "$http_user_agent"'; sendfile on; tcp_nopush on; keepalive_timeout 30; client_header_timeout 3m; client_body_timeout 3m; send_timeout 3m; connection_pool_size 256; client_header_buffer_size 1k; large_client_header_buffers 8 4k; request_pool_size 4k; output_buffers 4 32k; postpone_output 1460; client_max_body_size 10m; client_body_buffer_size 256k; client_body_temp_path /usr/local/nginx/client_body_temp; proxy_temp_path /usr/local/nginx/proxy_temp; fastcgi_temp_path /usr/local/nginx/fastcgi_temp; fastcgi_intercept_errors on; tcp_nodelay on; gzip on; gzip_min_length 1k; gzip_buffers 4 8k; gzip_comp_level 5; gzip_http_version 1.1; gzip_types text/plain application/x-javascript text/css text/htm application/xml; include vhost/*.conf; //新增这一行，定义默认虚拟主机的目录} 第一次配置的时候，出现提示 “ } ”这个所在行语法错误，一直找不到原因，最后重新粘贴配置文件以后，发现只是新增的“include vhost/*.conf ”配置最后没有添加“ ; ”分号结尾。
创建虚拟主机的目录
[root@aminglinux-02 conf]# pwd/usr/local/nginx/conf[root@aminglinux-02 conf]# mkdir vhost[root@aminglinux-02 conf]# lsfastcgi.conf fastcgi_params.default mime.types nginx.conf.default scgi_params.default vhostfastcgi.conf.default koi-utf mime.types.default nginx.conf.old uwsgi_params win-utffastcgi_params koi-win nginx.conf scgi_params uwsgi_params.default定义新增虚拟主机的配置[root@aminglinux-02 conf]# cd vhost/[root@aminglinux-02 vhost]# pwd/usr/local/nginx/conf/vhostserver{ listen 80 default_server; //有这个“default_server ”就是表示这是一个默认虚拟主机 server_name aaa.com; //指定主机名 index index.html index.htm index.php; //指定索引页 root /data/wwwroot/default; //指定root的目录} 创建网站的根目录
[root@aminglinux-02 vhost]# mkdir /data/wwwroot[root@aminglinux-02 vhost]# mkdir /data/wwwroot/default[root@aminglinux-02 vhost]# cd !$cd /data/wwwroot/default[root@aminglinux-02 default]# ls
在“/data/wwwroot/default “下创建索引页
[root@aminglinux-02 default]# vim index.htmlThis is the default site.
编辑好之后检查一下是否有语法的错误
[root@aminglinux-02 default]# /usr/local/nginx/sbin/nginx -tnginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is oknginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
重新加载nginx服务（更改配置文件以后，要重新加载或者重启一下服务）
[root@aminglinux-02 default]# /usr/local/nginx/sbin/nginx -s reload
测试一下访问默认页
[root@aminglinux-02 default]# curl localhostThis is the default site.[root@aminglinux-02 default]# lsindex.html
因为修改了nginx.conf的配置，现在看到的默认索引页，是我们刚刚新增的vhost的虚拟主机的索引页了
定义默认虚拟主机的两种办法：
- 默认虚拟主机，是根据目录的第一个.conf了进行选择，所以只需要在vhost目录下依次创建就可以了，当然这种方法不智能
- 只需要在vhost目录的.conf配置文件内，加上一个“default_server ”即可，把当前的这个配置对应的网站设置为第一个默认虚拟主机
12.8 Nginx用户认证
配置Nginx用户认证
新建一个虚拟主机配置文件[root@aminglinux-02 vhost]# vim test.com.confserver{ listen 80 ; server_name test.com; index index.html index.htm index.php; root /data/wwwroot/test.com;location / //表示全站，都需要进行用户认证#location /admin // 这个地方只要加上" /admin " 就变成 针对这个站点的“admin” 这个目录需要用户认证#location ~ admin.php //如果把这行这样写，就会变成，匹配 “ admin.php ”这个页面的时候才需要用户认证 { auth_basic "Auth"; //定义用户认证的名字 auth_basic_user_file /usr/local/nginx/conf/htpasswd; //用户名、密码文件 }} 虚拟机创建好之后，创建所需的目录及文件
[root@aminglinux-02 vhost]# cd /data/wwwroot/[root@aminglinux-02 wwwroot]# lsdefault[root@aminglinux-02 wwwroot]# mkdir test.com[root@aminglinux-02 wwwroot]# lsdefault test.com[root@aminglinux-02 test.com]# vim index.htmltest.com
配置弄好了，需要生产密码文件
需要用到Apache生成密码文件的工具“ htpasswd ” 两种情况： 1.如果本机安装有Apache，可以直接到所在目录运行htpasswd进行生成 2.如果没有安装，直接“ yum install -y httpd ”安装，因为yum安装的，所以工具存放在/usr/bin/下，可以直接使用htpasswd生成密码文件
[root@aminglinux-02 vhost]# htpasswd -c /usr/local/nginx/conf/htpasswd amingNew password:Re-type new password:Adding password for user aming[root@aminglinux-02 vhost]# cat /usr/local/nginx/conf/htpasswdaming:$apr1$45TTsuN4$9sOnkf8GUOVuCoWI2PcyL/
==关于htpasswd -c 命令 第一次创建的时候因为没有htpasswd这个文件，需要-c创建，第二使用的时候因为已经有这个htpasswd文件了，将不再需要-c 选项，如果还继续使用-c 这个选项，将会重置 htpasswd里的东西==
测试-c 是否会重置htpasswd文件
[root@aminglinux-02 vhost]# htpasswd -c /usr/local/nginx/conf/htpasswd user1New password:Re-type new password:Adding password for user user1[root@aminglinux-02 vhost]# !catcat /usr/local/nginx/conf/htpasswduser1:$apr1$I/VKfzgJ$KTWtCG4aZhrvLU69tgvhl1[root@aminglinux-02 vhost]# htpasswd /usr/local/nginx/conf/htpasswd amingNew password:Re-type new password:Adding password for user aming[root@aminglinux-02 vhost]# !catcat /usr/local/nginx/conf/htpasswduser1:$apr1$I/VKfzgJ$KTWtCG4aZhrvLU69tgvhl1aming:$apr1$idtTK3wd$RLibX1IYqH1x.rc6VibVg1
测试一下语法
[root@aminglinux-02 vhost]# /usr/local/nginx/sbin/nginx -tnginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is oknginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
重新加载服务
[root@aminglinux-02 vhost]# /usr/local/nginx/sbin/nginx -s reload
==重新加载服务的好处在于，如果配置里面出错，将不会生效；如果是直接使用restart，如果配置有错，将会直接影响到网站的运行==
测试 location / 针对整个站点进行用户认证
因为修改配置的时候做的配置，就是针对整个站点配置的，直接对域名进行curl即可
[root@aminglinux-02 test.com]# curl -x127.0.0.1:80 test.com -IHTTP/1.1 401 UnauthorizedServer: nginx/1.12.1Date: Thu, 10 Aug 2017 17:33:37 GMTContent-Type: text/htmlContent-Length: 195Connection: keep-aliveWWW-Authenticate: Basic realm="Auth"
提示错误码401，需要进行认证，认证方式 Basic realm="Auth"
使用指定用户测试
[root@aminglinux-02 test.com]# curl -x127.0.0.1:80 -uaming:123123 test.com -IHTTP/1.1 200 OKServer: nginx/1.12.1Date: Thu, 10 Aug 2017 17:36:04 GMTContent-Type: text/htmlContent-Length: 9Last-Modified: Thu, 10 Aug 2017 17:35:22 GMTConnection: keep-aliveETag: "598c995a-9"Accept-Ranges: bytes
测试 location /admin 针对目录
修改test.com.conf
location /
更改为
location /admin
到站点目录下加创建一个admin 的目录，为了方便测试，创建一测试页
[root@aminglinux-02 test.com]# pwd/data/wwwroot/test.com[root@aminglinux-02 test.com]# mkdir admin[root@aminglinux-02 test.com]# ls1.html admin index.html[root@aminglinux-02 test.com]# echo "admin-->test.com-->auth" > admin/login.php[root@aminglinux-02 test.com]# cat admin/login.phpadmin-->test.com-->auth[root@aminglinux-02 test.com]# curl -x127.0.0.1:80 test.com/admin/login.php -IHTTP/1.1 401 UnauthorizedServer: nginx/1.12.1Date: Thu, 10 Aug 2017 17:43:44 GMTContent-Type: text/htmlContent-Length: 195Connection: keep-aliveWWW-Authenticate: Basic realm="Auth"[root@aminglinux-02 test.com]# curl -x127.0.0.1:80 -uaming:123123 test.com/admin/login.php -IHTTP/1.1 200 OKServer: nginx/1.12.1Date: Thu, 10 Aug 2017 17:44:26 GMTContent-Type: application/octet-streamContent-Length: 24Last-Modified: Thu, 10 Aug 2017 17:41:45 GMTConnection: keep-aliveETag: "598c9ad9-18"Accept-Ranges: bytes
测试 location ~ 1.html 针对固定的URL
修改test.com.conf
location /admin
更改为
location ~ 1.html
创建所需的1.html
[root@aminglinux-02 test.com]# pwd/data/wwwroot/test.com[root@aminglinux-02 test.com]# vim 1.htmlThis is the default site.test.com [root@aminglinux-02 test.com]# ls1.html admin index.html[root@aminglinux-02 test.com]# curl -x127.0.0.1:80 test.com/1.html -IHTTP/1.1 401 UnauthorizedServer: nginx/1.12.1Date: Thu, 10 Aug 2017 17:50:19 GMTContent-Type: text/htmlContent-Length: 195Connection: keep-aliveWWW-Authenticate: Basic realm="Auth"[root@aminglinux-02 test.com]# curl -x127.0.0.1:80 -uaming:123123 test.com/1.html -IHTTP/1.1 200 OKServer: nginx/1.12.1Date: Thu, 10 Aug 2017 17:50:42 GMTContent-Type: text/htmlContent-Length: 35Last-Modified: Thu, 10 Aug 2017 16:57:21 GMTConnection: keep-aliveETag: "598c9071-23"Accept-Ranges: bytes
12.9 Nginx域名重定向
在Nginx里“ server_name ” 支持跟多个域名；但是Apache“ server_name ”只能跟一个域名，需要跟多个域名，需要使用Alisa
在Nginx的conf配置文件里“server_name ” 设置了多个域名，就会使网站的权重变了，到底需要哪个域名为主站点呢 所以需要域名重定向 更改配置“test.com.conf ”文件server{ listen 80 ; server_name test.com; index index.html index.htm index.php; root /data/wwwroot/test.com; if ($host != 'test.com' ) //假如域名，“!=”不等于 test.com，将执行下面的脚本 { rewrite ^/(.*)$ http://test.com/$1 permanent; // ^/(.*)$ 正式写法 http://$host/(.*)$ 这段可以直接省略掉的，同时还可以加上一些规则，“ permanent ”就是301的意思；如果想弄成302，只需要更改为“ redirect ” }location ~ 1.html { auth_basic "Auth"; auth_basic_user_file /usr/local/nginx/conf/htpasswd; }} 改好配置，检查语法，重新加载服务
[root@aminglinux-02 test.com]# /usr/local/nginx/sbin/nginx -tnginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is oknginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful(reverse-i-search)`s': /usr/local/nginx/^Cin/nginx -t[root@aminglinux-02 test.com]# /usr/local/nginx/sbin/nginx -s reload
