学搭建Nginx环境，必须要配置的Nginx.conf文件中，如下：
#user nobody;
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;
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
}
一般我们初学的，不可能一下子把配置文件一下子搭出来。要逐个模块去了解，注释部分可以先去掉，接下来就可以用这个命令进行排除掉#和空行
语法
grep -v ‘#|^$‘ filename
egrep -v ‘#|^$‘ filename
命令的作用
grep, egrep, fgrep - print lines matching a pattern
参数：
-v, --invert-match 排除
-E, --extended-regexp
egrep -i ‘devops‘ file 不考虑sam的大小写,含有sam的行.
egrep -l "dear ken" * 包含dear ken的所有文件的清单.
egrep -n tom file 包含tom的行, 每行前面追加行号.
egrep -s "$name" file 找到变量名$name的, 不打印而是显示退出状态. 0表示找到. 1表示表达式没找到符合要求的, 2表示文件没找到.
实例：
[[email protected] conf]# egrep -v ‘#|^$‘ nginx.conf.default > nginx.conf
[[email protected] conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
去掉注释#和空行后，看起来就舒服多了。
