通过二进制包安装mysql5.7数据库

1.下载mysql二进制安装包和依赖包

wget http://mirror.centos.org/centos/7/os/x86_64/Packages/libaio-devel-0.3.109-13.el7.x86_64.rpm wget http://mirror.centos.org/centos/7/os/x86_64/Packages/libaio-0.3.109-13.el7.x86_64.rpm wget https://mirrors.tuna.tsinghua.edu.cn/mysql/downloads/MySQL-5.7/mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz

2.安装依赖包并解压mysql二进制安装包

#yum -y install numactl  ##error while loading shared libraries: libnuma.so.1 #yum -y install openssl  ##[ERROR]   Could not find OpenSSL on the system rpm -ivh libaio-0.3.109-13.el7.x86_64.rpm rpm -ivh libaio-devel-0.3.109-13.el7.x86_64.rpm tar -xzvf mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz mv ./mysql-5.7.25-linux-glibc2.12-x86_64  /usr/local/mysqlrun

3.创建mysql运行用户和用户组

groupadd mysql useradd -M -g mysql -s /sbin/nologin mysql

4.创建数据目录和日志目录并授予权限

mkdir -p /usr/local/mysqldata/data mkdir -p /usr/local/mysqldata/binlogs mkdir -p /usr/local/mysqldata/relaylogs touch /usr/local/mysqldata/mysql-error.log chown -R mysql:mysql  /usr/local/mysqldata chmod -R 770  /usr/local/mysqldata chown -R mysql:mysql  /usr/local/mysqlrun chmod -R 770  /usr/local/mysqlrun

5.创建并配置my.cnf

mv  /etc/my.cnf  /etc/my.cnf_bak`date "+%Y%m%d%H%M"` cat << EOF >  /etc/my.cnf [mysqld] user=mysql port=3306 #server-id=1 #binlog_format = ROW #max_binlog_size = 1G #expire_logs_days = 7 #log-bin=/usr/local/mysqldata/binlogs/mysql-bin #relay-log=/usr/local/mysqldata/relaylogs/slave-relay-bin skip-grant-tables log-error=/usr/local/mysqldata/mysql-error.log datadir=/usr/local/mysqldata/data basedir=/usr/local/mysqlrun socket=/usr/local/mysqlrun/mysql.sock pid-file=/usr/local/mysqlrun/mysql.pid skip-name-resolve symbolic-links = 0 lower_case_table_names = 1 character-set-server = utf8 default-storage-engine = InnoDB innodb_file_per_table = 1 max_connections = 2000 max_allowed_packet = 1G interactive_timeout = 120 wait_timeout = 864000 [mysql] socket=/usr/local/mysqlrun/mysql.sock EOF

6.初始化mysql数据库

/usr/local/mysqlrun/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysqlrun --datadir=/usr/local/mysqldata/data /usr/local/mysqlrun/bin/mysql_ssl_rsa_setup  --datadir=/usr/local/mysqldata/data

7.设定启动脚本中basedir和datadir的路径

sed   -i   '/^basedir/c\basedir=\/usr\/local\/mysqlrun'   /usr/local/mysqlrun/support-files/mysql.server sed   -i   '/^datadir/c\datadir=\/usr\/local\/mysqldata\/data'   /usr/local/mysqlrun/support-files/mysql.server

8.将mysql工具添加到环境变量中

echo 'export PATH=/usr/local/mysqlrun/bin:$PATH' >> /etc/profile source /etc/profile

9.设置mysql服务开机自启并启动

ln -s /usr/local/mysqlrun/support-files/mysql.server  /etc/init.d/mysqld chmod +x /etc/init.d/mysqld chkconfig --add mysqld chkconfig mysqld on chkconfig --list systemctl enable mysqld systemctl restart mysqld && systemctl status mysqld #/usr/local/mysqlrun/bin/mysqld_safe --defaults-file=/etc/my.cnf & #ps -ef | grep mysql | grep -v grep | awk '{print $2}' |xargs kill -9

10.重置mysql数据库root密码(无需重启)

ROOT_PASSWD='m4r!adbOP' ROOT_PASSWD_T='m4r\!adbOP' mysql -uroot -e "update mysql.user set authentication_string=password('${ROOT_PASSWD_T}') where user='root';" mysql -uroot -e "flush privileges;" sed -i 's/^skip-grant-tables/#&/'   /etc/my.cnf mysql --connect-expired-password -uroot -p"${ROOT_PASSWD}" -e "ALTER USER 'root'@'localhost' IDENTIFIED BY '${ROOT_PASSWD_T}';" mysql --connect-expired-password -uroot -p"${ROOT_PASSWD}" -e "flush privileges;" mysql -uroot -p"${ROOT_PASSWD}" -e "show databases;"

11.设置mysql远程访问

mysql -uroot -p"${ROOT_PASSWD}" -e "update mysql.user set host='%' where user='root' and host='localhost';" mysql -uroot -p"${ROOT_PASSWD}" -e "select user,host from mysql.user;"

12.放开防火墙(防火墙关闭也无需操作)

firewall-cmd --permanent --zone=public --add-port=3306/tcp firewall-cmd --reload
