First of all
If the host is installed docker, he nginx will generate a file in the directory /etc/logrotate.d
nginx and host environment lacks distinction, that is to execute the command to change to change a little on the line
PS: If you look at the nginx docker installation https://blog.csdn.net/wu__peng/article/details/90904409
1, copy a file, change a name docker_nginx, document reads as follows, after a slight modification
(Below the nginx_01, my vessel name, herself to look into their own time on the line;
/ Home / nginx / logs is my log storage path.
)
/home/nginx/logs/*log {
su root root
create 0644 nginx nginx
daily
rotate 30
missingok
notifempty
compress
sharedscripts
postrotate
docker exec nginx_01 bash -c "if [ -f /run/nginx.pid ]; then kill -USR1 `docker exec nginx_01 cat /run/nginx.pid`; echo 日志打包完毕; fi"
endscript
}
2, the detection
logrotate -d -f /etc/logrotate.d/docker_nginx
3. execution (performed manually, automatically executed without waiting)
logrotate -f /etc/logrotate.d/docker_nginx
logrotate arguments detailed:
daily #指定转储周期为每天
weekly #指定转储周期为每周;
monthly #指定转储周期为每月;
rotate count #指定日志文件删除之前转储的次数,0指没有备份,5指保留5个备份;
compress #通过gzip压缩转储以后的日志;
nocompress #不需要压缩时,用这个参数;
delaycompress #延迟压缩,和compress一起使用时,转储的日志文件到下一次转储时才压缩;
nodelaycompress #覆盖delaycompress选项,转储同时压缩;
copytruncate #用于还在打开中的日志文件,把当前日志备份并截断;
nocopytruncate #备份日志文件但是不截断;
create mode owner group #转储文件,使用指定的文件模式创建新的日志文件;
nocreate #不建立新的日志文件;
errors address #专储时的错误信息发送到指定的Email地址;
ifempty #即使是空文件也转储,这个是logrotate的缺省选项;
notifempty #如果是空文件的话,不转储;
mail address #把转储的日志文件发送到指定的E-mail地;
nomail #转储时不发送日志文件;
olddir directory #转储后的日志文件放入指定的目录,必须和当前日志文件在同一个文件系统;
noolddir #转储后的日志文件和当前日志文件放在同一个目录下;
prerotate/endscript #在转储以前需要执行的命令可以放入这个对,这两个关键字必须单独成行;
postrotate/endscript #在转储以后需要执行的命令可以放入这个对,这两个关键字必须单独成行;
tabootext [+] list #让logrotate不转储指定扩展名的文件,缺省的扩展名是:.rpm-orig, .rpmsave,v,和~ ;
size size #当日志文件到达指定的大小时才转储,Size可以指定bytes(缺省)以及KB(sizek)或者MB(sizem);
postrotate <s> endscript #日志轮换过后指定指定的脚本,endscript参数表示结束脚本;
sharedscripts #共享脚本,下面的postrotate <s> endscript中的脚本只执行一次即可;
