生产环境安装mysql5.7及备份

一：规划目录

yum install -y libaio     #安装依赖
tar zxf /root/mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz -C /usr/local/      #需要事先下载好二进制包
mv /usr/local/mysql-5.7.22-linux-glibc2.12-x86_64/ /usr/local/mysql
echo "export PATH=$PATH:/usr/local/mysql/bin" >/etc/profile.d/mysql.sh
source /etc/profile.d/mysql.sh
useradd mysql;echo 123456|passwd --stdin mysql
mkdir -p /data/mysql
chown -R mysql:mysql /data/mysql
chmod -R 755 /data/mysql

二：修改配置文件

vim /etc/my.cnf

[mysqld]
datadir=/data/mysql
socket=/data/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
character_set_server=utf8
init_connect='SET NAMES utf8'
lower_case_table_names=1

# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd

[mysqld_safe]
log-error=/data/mysql/mysql.log
pid-file=/data/mysql/mysql.pid

# include all files from the config directory
!includedir /etc/my.cnf.d

三：开始二进制编译并启动

/usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql --initialize-insecure
cp /usr/local/mysql/support-files/mysql.server  /etc/init.d/mysql
/etc/init.d/mysql start
netstat -lntup|grep 3306

四：设置并初始化数据库

mysql -uroot -S /data/mysql/mysql.sock
ALTER USER 'root'@'localhost' IDENTIFIED BY 'passwd';
grant all privileges on *.* to root@'%' identified by 'passwd' with grant option;
flush privileges;
