CentOS 7 - MySQL 5.7 소스설치

MySQL 은 데이타베이스의 한 종류로 많은 사용자를 가진 무료 RDBMS 입니다.

리눅스 DB 서버라고 하면 대부분 MySQL 이 설치되어있으며, 홈페이지의 회원정보, 결제정보, 게시물 내용 등을 저장하거나 ERP 데이타 수집 및 관리 목적으로도 사용되는 등 데이타 저장 및 조회를 위해 다양하게 활용이 됩니다.

Oracle 데이타베이스를 개발하는 썬마이크로시스템즈사에서 에서 MySQL을 인수하여 대대적인 버그 수정을 하고 퍼포먼스를 향상 시켜왔기 때문에 어느정도 안정적이라 볼 수 있으며 무엇보다 무료로 사용할 수 있기에 인기가 많습니다.

아래 설치과정은 CentOS7 환경에서 진행했습니다.

Mysql 설치

1. 필수 구성요소 설치

imap 관련 64비트 32비트 라이브러리 설정

# ln -s /usr/lib64/libc-client.a /usr/lib/libc-client.a

# unlink /usr/include/db.h

# ln -s /usr/include/libdb4/db.h /usr/include/db.h

# ln -s /usr/include/sqlext.h /usr/local/include/sqlext.h

# ln -s /usr/lib64/libgdbm_compat.so /usr/local/lib64/libdbm.so

openldap 호환

# \cp -arpf /usr/lib64/libldap* /usr/lib/

# ln -sf /usr/lib64/libm.so /usr/lib/libm.so

# ln -sf /usr/lib64/libssl.so /usr/lib/libssl.so

2. default 환경변수 설정

# echo " " >> /etc/profile

# echo "####default PATH#####" >> /etc/profile

# echo "export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:" >> /etc/profile

# echo "#####################" >> /etc/profile

3. MySQL 계정 추가

# groupadd -g 400 mysql

# useradd -u400 -g400 -d /usr/local/mysql -s /bin/false mysql

* MySQL 설치 및 실행하기 위해서는 mysql 계정이 필요합니다.

4. MySQL 설치

# mkdir -p /usr/local/src/APM_Setup

# cd /usr/local/src/APM_Setup

# wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.40.tar.gz

# tar zxvf mysql-5.7.40.tar.gz

# mkdir -p /usr/local/src/APM_Setup/mysql-5.7.40/build

# cd mysql-5.7.40/build

# cmake ../ \

# make -j쓰레드 갯수

# make install

※ 언어셋을 euckr로 설치를 원할 경우, -DDEFAULT_CHARSET=euckr -DDEFAULT_COLLATION=euckr_korean_ci로 변경해줍니다.

5. my.cnf 파일 설정

# mv /etc/my.cnf /etc/my.cnf_source_beforce

# echo "####### Tin light and shade

[client]
default-character-set = utf8
port = 3306
socket = /tmp/mysql.sock

[mysqld]
#default-character-set = utf8
socket = /tmp/mysql.sock
datadir = /usr/local/mysql/data
basedir = /usr/local/mysql
user = mysql
bind-address = 0.0.0.0
skip-external-locking

server-id=1

#long_query_time = 3
#log-slow-queries = /usr/local/mysql/logs/mysql-slow-queries.log

6. boost 설치

# cd /usr/local/include/boost/boost_1_59_0

# ./bootstrap.sh

# ./b2 install

* MySQL 5.7 부터는 기하연산에 쓰이는 코드들이 들어있는 라이브러리를 사용합니다. 그렇기 때문에 설치를 해야합니다.

7. 데이터베이스 구성 및 권한 설정

# mkdir -p /usr/local/mysql/tmp

# mkdir -p /usr/local/mysql/logs

# chmod 711 /usr/local/mysql

# mkdir /usr/local/mysql/data

# chmod 700 /usr/local/mysql/data

# chmod 751 /usr/local/mysql/bin/

# chmod 750 /usr/local/mysql/bin/*

# chmod 755 /usr/local/mysql/bin/mysql

# chmod 755 /usr/local/mysql/bin/mysqldump

# chown -R mysql:mysql /usr/local/mysql/

8. MySQL 데이터 실행 초기화 생성

# /usr/local/mysql/bin/mysqld --initialize-insecure --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

* 여기서 --initialize-insecure 해당 옵션이 설치할때 mysql root 비밀번호를 임시 발급받는 패스워드로 설정하지 않겠다는 옵션입니다.

9. 자동 실행 설정 및 환경 변수 적용

# \cp -arpf /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

# chmod 700 /etc/init.d/mysqld

# chkconfig --add mysqld

# chkconfig --level 3 mysqld on

10. MySQL root 초기패스워드 설정

# /etc/init.d/mysqld restart

# /usr/local/mysql/bin/mysql -u root -e 'use mysql; update user set authentication_string=password("설정할 패스워드") where user="root"; flush privileges;'

11. 소스 설치한 MySQL 환경변수 설정

# echo " " >> /etc/profile

# echo "APACHE_HOME=/usr/local/apache" >> /etc/profile

# echo "MySQL_HOME=/usr/local/mysql" >> /etc/profile

# echo "PHP_HOME=/usr/local/php" >> /etc/profile

# echo " " >> /etc/profile

# echo "export PATH="\$"APACHE_HOME/bin:"\$"MySQL_HOME/bin:"\$"PHP_HOME/bin:"\$"PHP_HOME/sbin"\$"{PATH:+:"\$"{PATH}}" >> /etc/profile

# echo " " >> /etc/profile

# source /etc/profile

12. 데몬 구동 확인

# netstat -ntlp
