一、Nginx 安装
系统平台：CentOS release 7.2 (Final) 64位。
通过yum安装
1.添加nginx的源
rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
该命令执行之后，会在/etc/yum.respos.d下面多出一个nginx.repo
2.执行安装命令
yum install -y nginx
3.安装之后，可以查看nginx的默认安装目录
whereis nginx
nginx: /usr/sbin/nginx /usr/lib64/nginx /etc/nginx /usr/share/nginx /usr/share/man/man8/nginx.8.gz
pwd
/etc/yum.repos.d
4.以下是Nginx的默认路径：
(1) Nginx配置路径：/etc/nginx/
(2) PID目录：/var/run/nginx.pid
(3) 错误日志：/var/log/nginx/error.log
(4) 访问日志：/var/log/nginx/access.log
(5) 默认站点目录：/usr/share/nginx/html
5.测试指令
nginx 启动
nginx -t 测试命令

通过安装包安装
一、安装编译工具及库文件
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel
二、首先要安装 PCRE
PCRE 作用是让 Nginx 支持 Rewrite 功能。
1、下载 PCRE 安装包，下载地址：http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
[root@bogon src]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
2、解压安装包:
[root@bogon src]# tar zxvf pcre-8.35.tar.gz
3、进入安装包目录
[root@bogon src]# cd pcre-8.35
4、编译安装
[root@bogon pcre-8.35]# ./configure[root@bogon pcre-8.35]# make && make install
5、查看pcre版本
[root@bogon pcre-8.35]# pcre-config --version
安装 Nginx
1、下载 Nginx，下载地址：http://nginx.org/download/nginx-1.9.9.tar.gz
[root@bogon src]# wget http://nginx.org/download/nginx-1.9.9.tar.gz
2、解压安装包
[root@bogon src]# tar zxvf nginx-1.9.9.tar.gz
3、进入安装包目录
[root@bogon src]# cd nginx-1.9.9
4、编译安装
[root@bogon nginx-1.9.9]# ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35
[root@bogon nginx-1.9.9]# make[root@bogon nginx-1.9.9]# make install
5、查看nginx版本
[root@bogon nginx-1.9.9]# /usr/local/webserver/nginx/sbin/nginx -v
到此，nginx安装完成。
二、Nginx 配置
创建 Nginx 运行使用的用户 www：
[root@bogon conf]# /usr/sbin/groupadd www
[root@bogon conf]# /usr/sbin/useradd -g www www
配置nginx.conf ，将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容
[root@bogon conf]# vim /usr/local/webserver/nginx/conf/nginx.conf
user www www;
worker_processes 1;
error_log logs/error.log;
error_log logs/error.log notice;
error_log logs/error.log info;
pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log logs/access.log main;
sendfile on;
tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
gzip on;
include conf.d/*.conf;
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
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;
# }
#}
}
创建conf.d文件夹
mkdir confi.d
指定配置文件地址
/usr/local/webserver/nginx/sbin/nginx -c /usr/local/webserver/nginx/conf/nginx.conf
增加环境变量
vim /etc/profile
添加 export PATH=/usr/local/webserver/nginx/sbin/nginx
使环境变量生效
source /etc/profile
执行 nginx -v，出现nginx版本及配置成功
执行 nginx -s start，启动服务
三、nginx常用指令
nginx -s start #启动nginx
nginx -s reload # 重新载入配置文件
nginx -s reopen # 重启 Nginx
nginx -s stop # 停止 Nginx
