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:
[root@web01 conf]# egrep -v '#|^$' nginx.conf.default > nginx.conf
[root@web01 conf]# cat nginx.confworker_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。
