# -c 指定了配置文件的路径
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
停止：
# 查找主进程号
ps -ef | grep nginx
# 从容停止
kill -QUIT nginx主进程号
# 快速停止
kill -TERM nginx主进程号
kill -INT nginx主进程号
# 强制停止
kill -9 nginx主进程号
# 强制停止所有nginx
pkill -9 nginx
killall nginx
nginx主进程号可以使用
`cat /usr/local/nginx/logs/nginx.pid` 或 $( cat /usr/local/nginx/logs/nginx.pid )
平滑重启：
# 判断配置文件是否正确
/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
# 平滑重启
kill -HUP nginx主进程号
alias用法：
# 一般情况下，在location /中配置root，在location /other中配置alias
location /mydir/ {
alias /var/myuser/mydir/;
# 激活/关闭自动索引 默认为 off
autoindex on;
# 设定索引文件大小的单位(B,KB,MB,GB) 默认为 on
autoindex_exact_size off;
# 开启以本地时间来显示文件时间 默认为 off
autoindex_localtime on;
}
rewrite用法:
# 目录不存在
if ( !-d $request_filename )
{
rewrite "/epg/([0-9]{8})(.*)" /mydir/current/ last;
}
http负载均衡用法:
# 总体格式
http
{
# weight-权重，越高，被分的客户端连接越多。默认权重1
# max_fails-在参数 fail_timeout 指定时间内 请求失败的次数。默认为1，设置为0关闭此检查
# down-永久离线状态
# backup-仅仅在非backup服务器全部宕机或繁忙时启用
upstream epg_server_pool {
server 192.168.3.227:80 weight=1 max_fails=2 fail_timeout=30s;
server 192.168.3.228:80 weight=1 max_fails=2 fail_timeout=30s;
server 192.168.3.229:80 down
server 192.168.3.243:80 backup
}
server {
listen 80;
server_name localhost;
location / {
#ip_hash
proxy_pass http://epg_server_pool
}
}
}
tcp负载均衡用法
# 总体格式
tcp {
upstream auth_pool {
# the upstream server will be dispatched by ip_hash.
# ip_hash
server 192.168.3.242:5203;
server 192.168.3.243:5203;
# interval-the check request's interval time.
# rise-After rise_count check success, the server is marked up.
# fall-After rise_count check success, the server is marked up.
# timeout-the check request's timeout.
# type-the check protocol type.
check interval=3000 rise=2 fall=5 timeout=1000;
}
server {
listen 5203;
proxy_pass auth_pool;
# set the timeout value with clients. default: 60000 milliseconds
timeout 60000;
}
# set the timeout value of connection to backends.default: 60000 milliseconds
#proxy_connect_timeout 60000
# set the timeout value of reading from backends.default: 60000 milliseconds
#proxy_read_timeout 60000
# set the timeout value of sending to backends.default: 60000 milliseconds
#proxy_send_timeout 60000
}
切割Nginx日志脚本:
#1-编辑脚本
vi /usr/local/nginx/sbin/cut_nginx_log.sh
#!/bin/bash
# This script run at 00:00
# The Nginx logs path
logs_path="/usr/local/nginx/logs/"
mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 `cat /usr/local/nginx/logs/nginx.pid`
#2-设置crontab
crontab -e
00 00 * * * /usr/local/nginx/sbin/cut_nginx_log.sh
