最近开始梳理服务器的部署文档，先记录一下Nginx的安装和配置
Nginx 安装
安装编译工具及库文件
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel安装 PCRE
yum install -y pcre pcre-devel
PCRE 作用是让 Nginx 支持 Rewrite 功能。
查看PCRE版本：[root@bogon pcre-8.35]# pcre-config --version
- 下载 Nginx
[root@bogon src]# cd /usr/local/src/
[root@bogon src]# wget http://nginx.org/download/nginx-1.6.2.tar.gz解压nginx
[root@bogon src]# tar zxvf nginx-1.6.2.tar.gz- 编译安装
[root@bogon src]# cd nginx-1.6.2
[root@bogon nginx-1.6.2]# ./configure
[root@bogon nginx-1.6.2]# make
[root@bogon nginx-1.6.2]# make install到此，nginx安装完成。
Nginx 配置
- 创建用户
[root@bogon conf]# /usr/sbin/groupadd nginx
[root@bogon conf]# /usr/sbin/useradd -g nginx nginx2.配置nginx.conf
user nginx nginx;
worker_processes 2; #设置值和CPU核心数一致
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别
pid /usr/local/webserver/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;
events
{
use epoll;
worker_connections 65535;
}
http
{
include mime.types;
default_type application/octet-stream;

#下面是server虚拟主机的配置
server
{
listen 80;#监听端口
server_name localhost;#域名
index index.html index.htm index.php;
root /usr/local/webserver/nginx/html;#站点目录
location ~ .*\.(php|php5)?$
{
#fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|ico)$
{
expires 30d;
# access_log off;
}
location ~ .*\.(js|css)?$
{
expires 15d;
# access_log off;
}
access_log off;
}
}检查配置文件nginx.conf的正确性命令：
[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx -t启动Nginx
[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx- Nginx其它命令
/usr/local/webserver/nginx/sbin/nginx -s reload # 重新载入配置文件
/usr/local/webserver/nginx/sbin/nginx -s reopen # 重启 Nginx
/usr/local/webserver/nginx/sbin/nginx -s stop # 停止 Nginx增加nginx虚拟主机配置文件(conf.d)
有时候我们按照了nginx后发现配置文件只有一个,/etc/nginx/nginx.conf
所有的配置包括虚拟目录也在此文件中配置, 这样当虚拟主机多了管理就有些不方便了,
这是需要我们把配置文件拆分开来,在/etc/nginx/conf.d/ 文件建立对应的域名配置文件,比如 /etc/nginx/conf.d/123.com.conf
只需要在原来文件/etc/nginx/nginx.conf 的http 块下加上：include /etc/nginx/conf.d/*.conf;
完整代码：
#user nginx nginx;
worker_processes 2;
#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;
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 $document_root$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;
# }
#}
include /etc/nginx/conf.d/*.conf;
}之后就可以把虚拟主机的配置文件写在/etc/nginx/conf.d/目录下了,如123.conf
server {
listen 80;
server_name 123.com;
#charset koi8-r;
#access_log /var/log/nginx/log/host.access.log main;
location / {
root /var/nginx/html/123.com;
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 /var/nginx/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 /var/nginx/html/123.com;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME $document_root$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;
#}
}
