리눅스 mysql5.6.23 설치

는 / usr / 지방 / 디렉토리로 업로드 mysql5.6.23 설치 패키지

      cd   /usr/local
     rz命令上传mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz

2. 설치 패키지를 추출하고, 이름을 변경

	tar -zxvf  mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
	mv  mysql-5.6.23-linux-glibc2.5-x86_64   mysql

3. 사용자 그룹 및 사용자 만들기

	groupadd -g 101 dba
	useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin

개인 환경 변수를 구성하는 단계에 따라 사용자의 홈 디렉토리 mysqladmin은 순서에 4. 복사 환경 변수 설정 파일

	cp   /etc/skel/.*    /usr/local/mysql 

5. 수정 프로필 /etc/my.cnf에

	vi  /etc/my.cnf

socket          = /usr/local/mysql/data/mysql.sock

[mysqld]

6. 권한 my.cmf 변경

chown  mysqladmin:dba /etc/my.cnf
chmod  640 /etc/my.cnf 

7.의 경우 / usr / local / mysql 디렉토리 권한을 변경

chown -R mysqladmin:dba /usr/local/mysql
chmod -R 755 /usr/local/mysql

참고 : 수정을 수정하는 것은 또 다른 살펴 보도록하겠습니다로 폴더해야 CD에 완료되면

8. 바이너리 로그 로그 저장 파일을 작성

[root@ruozedata001 ~]# su - mysqladmin
Last login: Fri Jun 28 14:01:40 CST 2019 on pts/2
ruozedata001:mysqladmin:/usr/local/mysql:>pwd
/usr/local/mysql
ruozedata001:mysqladmin:/usr/local/mysql:>mkdir   arch

9. 설치 스크립트 파일을 실행

scripts/mysql_install_db --user=mysqladmin  --basedir=/usr/local/mysql  --datadir=/usr/local/mysql/data
报错：Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory #缺少libaio.so 包
	 yum -y install libaio（安装libaio包）
scripts/mysql_install_db --user=mysqladmin  --basedir=/usr/local/mysql  --datadir=/usr/local/mysql/data

그런 다음 mount 명령을 수행

MySQL의 서비스가 자동으로 시작 10. 구성

#将服务文件拷贝到init.d下，并重命名为mysql
[root@ruozedata001 mysql]# cp  support-files/mysql.server  /etc/rc.d/init.d/mysql 
#赋予可执行权限
[root@ruozedata001 mysql]# chmod +x /etc/rc.d/init.d/mysql
#删除服务
[root@ruozedata001 mysql]#  chkconfig --del mysql
#添加服务
[root@ruozedata001 mysql]# chkconfig --add mysql
[root@ruozedata001 mysql]#  chkconfig --level 345 mysql on
[root@ruozedata001 mysql]#  vi /etc/rc.local(开机最先读取的配置文件)
	su - mysqladmin -c "/etc/init.d/mysql start"

환경 변수를 수정 11

ruozedata001:mysqladmin:/usr/local/mysql:>cat .bash_profile 
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs

export  MYSQL_HOME=/usr/local/mysql
export  PATH=${MYSQL_HOME}/bin:$PATH

unset USERNAME
set unmask to 022
umask 022

PS1=`uname -n`":"'$USER'":"'$PWD'":>";
export PS1
ruozedata001:mysqladmin:/usr/local/mysql:>

(12) 그리고 MySQL의 시작

ruozedata001:mysqladmin:/usr/local/mysql:>/etc/init.d/mysql  start
Starting MySQL. SUCCESS! 
ruozedata001:mysqladmin:/usr/local/mysql:>

참고 :이 서비스로 전환하는 것은 mysqladmin 데이터 mysql을 시작 할 수 있어야합니다

13 착륙 MySQL의 사용자와 수정하고 빈 MySQL의 root 사용자 암호를 삭제

ruozedata001:mysqladmin:/usr/local/mysql:>mysql -uroot -p

注意：只要mysql数据库已装好，就最好删除空用户和修改root的密码，不然会造成很多的bug，尤其是mysql数据库重新安装了后

당신은 데이터베이스 14.mysql를 다시 설치해야하는 경우

service mysql stop
rm -rf /usr/local/mysql/arch/*
rm -rf /usr/local/mysql/data/*
scripts/mysql_install_db  \
--user=mysqladmin \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data 
然后再好删除空用户和修改root的密码，不然会造成很多的bug.
