자체적으로 rotate되는 로그파일에 logrotate 적용하기
tomcat 기본설정 처럼 로그파일 이름이 자체적으로 rotate되어 버리는 경우, logrotate 로의 통합이 어렵다. 네이밍은 자체룰을 이용하고 압축을 하는 등 후작업을 logrotate에 넣는 방식으로 통합하는 방법이다.

Apache 2.4 IP-ACL for ELB (also any other Proxy/LB)
As you all know, we use the ‘X-Forwarded-For’ header to determine the IP of client when the HTTPD is behind the ELB (or other Proxy/LB). However it is very difficult to set the IP-ACL in Apache configuration files common to the cases with and without LB. (due to the Apache environment variables) So I have been operating under this settings for some services.

If you see “syntax error, unexpected $end”, just remove queotes of expressions. This is a bug of apache httpd.

Mysql General Procedures for DML using JSON data type
The new MySQL 5.7 version has some great features. One of them is the ‘JSON data’ type. We can use it for column of table like ‘Virtual Colunm’ with Indexing. But, ‘JSON data’ is also useful for stored procedure. Because we can compact parameters and the procedure could be more flexible.I made the procedures for table insert/update via JSON parameter. When I apply them to my project, data-handling codes in the application decreased dramatically. (These procedures impliment ‘MySQL Procedure Pattern for Nested Transaction‘)

Don’t use utf8 encoding in MySQL (>= 5.5.3)
오늘날 한국어/중국어/일본어등 2바이트 문자권에서의 SW개발 및 다국어를 대비한 문자열 인코딩은 거의 UTF-8로 통일화 되고 있다. 그런데, MySQL의 문자인코딩 중 utf8인코딩은 ‘진짜 UTF-8’이 아니다 ! 원래 UTF-8은 규약상 한 문자가 4바이트까지 사용하는데 MySQL의 utf8인코딩은 3바이트까지만 입력이 가능하기 때문이다. 대부분의 한중일 문자는 3바이트 코드로 표현이 가능한데, 특히 특수문자나 한자를 많이 사용하는 일본어 등에서는 심심치 않게 4바이트 문자에 의한 문제가 나타난다. 𠀋 𡈽 𡌛 𡑮 𡢽 𠮟 𡚴 𡸴 𣇄 𣗄 𣜿 𣝣 𣳾 𤟱 𥒎 𥔎 𥝱 𥧄 𥶡 𦫿 𦹀 𧃴 𧚄 𨉷 𨏍 𪆐 𠂉 𠂢 𠂤 𠆢 𠈓 𠌫 𠎁 ‥‥‥
