在centos 7 下，用nginx official repo安装的nginx stable版本的config 默认配置如下:
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/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 /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
include /etc/nginx/conf.d/*.conf;
}
但是很明显, 这个配置过于简单了，结合军哥的LNMP，我们可以稍微改动一下config:
user nginx;
worker_processes auto;
worker_cpu_affinity auto;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 51200;
events {
use epoll;
worker_connections 51200;
multi_accept off;
accept_mutex off;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 50m;
sendfile on;
sendfile_max_chunk 512k;
tcp_nopush on;
keepalive_timeout 60;
tcp_nodelay on;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.1;
gzip_comp_level 2;
gzip_types text/plain application/javascript application/x-javascript text/javascript text/css application/xml application/xml+rss;
gzip_vary on;
gzip_proxied expired no-cache no-store private auth;
gzip_disable "MSIE [1-6]\.";
#limit_conn_zone $binary_remote_addr zone=perip:10m;
##If enable limit_conn_zone,add "limit_conn perip 10;" to server section.
server_tokens off;
access_log off;
server {
listen 80 default_server;
server_name _;
index index.html index.htm index.php;
root /usr/share/nginx/html;
}
include /etc/nginx/conf.d/*.conf;
}
在CentOS7上，nginx的启动是有systemd 来管理的，位置在/usr/lib/systemd/system/nginx.service
配置文件为:
[Unit] Description=nginx - high performance web server Documentation=http://nginx.org/en/docs/ After=network-online.target remote-fs.target nss-lookup.target Wants=network-online.target [Service] Type=forking PIDFile=/var/run/nginx.pid ExecStart=/usr/sbin/nginx -c /etc/nginx/nginx.conf ExecReload=/bin/kill -s HUP $MAINPID ExecStop=/bin/kill -s TERM $MAINPID [Install] WantedBy=multi-user.target
