Centos7下mysql5.7二进制包安装

准备

mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz

注意：如果是虚拟机安装，建议设置的磁盘空间不要低于16G，否则安装时磁盘空间不够，会导致mysql初始化失败

环境准备

#解压二进制包到/usr/local/ ，重命名为mysql，并创建安装时需要的目录
tar -zxvf mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz -C /usr/local/
mv /usr/local/mysql-5.7.11-linux-glibc2.5-x86_64 /usr/local/mysql
cd /usr/local
mkdir mysql/arch mysql/data mysql/tmp mysql/relay_log
yum -y install libaio

添加配置文件

#在文件中添加下面配置信息，若配置文件已经存在，清空文件内容，在添加下面的配置
vi /etc/my.cnf

添加用户及用户组

groupadd -g 101 mysql
useradd -u 514 -g mysql -G root -d /usr/local/mysql mysql
usermod -u 514 -g mysql -G root -d /usr/local/mysql mysql
cp /etc/skel/.* /usr/local/mysql

配置mysql用户的环境变量

#清空文件，并添加下面内容
vi mysql/.bash_profile

.bash_profile文件内容

# .bash_profile
# Get the aliases and functions

if [ -f ~/.bashrc ]; then
	. ~/.bashrc
fi

# User specific environment and startup programs
export MYSQL_BASE=/usr/local/mysql
export PATH=${MYSQL_BASE}/bin:$PATH


unset USERNAME

#stty erase ^H
set umask to 022
umask 022
PS1=`uname -n`":"'$USER'":"'$PWD'":>"; export PS1

赋权限和用户组

chown  mysql:mysql /etc/my.cnf 
chmod  640 /etc/my.cnf
chown -R mysql:mysql /usr/local/mysql
chmod -R 755 /usr/local/mysql

配置服务及开机自启动

#将服务文件拷贝到init.d下，并重命名为mysql
cp mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld 
#赋予可执行权限
chmod +x /etc/rc.d/init.d/mysqld
#删除服务
chkconfig --del mysqld
#添加服务
chkconfig --add mysqld
chkconfig --level 345 mysqld on

安装mysql并初始化

#切换到mysql用户
su - mysql

#初始化mysql的db
bin/mysqld --defaults-file=/etc/my.cnf --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ --initialize
#在初始化时如果加上 –initial-insecure，则会创建空密码的 root@localhost 账号，否则会创建带密码#的 root@localhost 账号，密码直接写在 log-error 日志文件中
#（在5.6版本中是放在 ~/.mysql_secret 文件里，更加隐蔽，不熟悉的话可能会无所适从）

查看临时密码

cat data/hostname.err |grep password
#2019-07-27T07:23:18.351344Z 1 [Note] A temporary password is generated for root@localhost: (13dRixi_pIs
#临时密码：(13dRixi_pIs)


#启动mysql
/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &

#登录及修改用户密码，'(13dRixi_pIs' 是临时密码
bin/mysql -urot -p'(13dRixi_pIs'

#修改密码，以及添加mysql远程访问
alter user root@localhost identified by '123456';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION ;
flush privileges;
exit;
#重启mysql
service mysqld restart
#登录mysql
mysql -uroot -p123456
