linux mysql 自动安装脚本

 1.先安装依赖，依赖要是安装失败会中断执行

yum install -y cmake make gcc gcc-c++ libaio ncurses ncurses-devel

 2.然后就是  安装包   名字不一 样的替换一下就可以  mysql-5.7.30-linux-glibc2.12-x86_64.tar.gz

#!/bin/bash
  
cd /usr/local/src
pwd
tar -zxvf mysql-5.7.30-linux-glibc2.12-x86_64.tar.gz   
cp -r mysql-5.7.30-linux-glibc2.12-x86_64   /usr/local/mysql
groupadd mysql
useradd -r -g mysql mysql 
cd /usr/local/mysql
chown -R mysql:mysql ./

bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
cp /usr/local/mysql/support-files/mysql.server  /etc/init.d/mysqld
bin/mysql_ssl_rsa_setup --datadir=/usr/local/mysql/data
chown -R mysql:mysql ./
chown -R mysql:mysql data
echo "   
[mysqld]
character_set_server=utf8
init_connect='SET NAMES utf8'
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
socket=/tmp/mysql.sock
#不区分大小写 
lower_case_table_names = 1
#不开启sql严格模式
sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'
log-error=/var/log/mysqld.log
pid-file=/usr/local/mysql/data/mysqld.pid" > /etc/my.cnf
cp /usr/local/mysql/support-files/mysql.server  /etc/init.d/mysqld
sed -i "s#basedir=#basedir=/usr/local/mysql#"  /etc/init.d/mysqld 
sed -i "s#datadir=#datadir=/usr/local/mysql/data#"  /etc/init.d/mysqld 
ln -s /usr/local/mysql/bin/mysql /usr/bin
chmod +x /etc/init.d/mysqld
# 加入开机起动   
#chkconfig --add mysqld 
#5、启动mysql   service mysqld start 
#
# 
##登录修改密码 mysql -uroot -p 上面初始化时的密码
# #grep 'temporary password' /usr/local/mysql/log/mysqld.log
#
#alter user 'root'@'localhost' identified by 'root';   
#
#GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'mysql.7335553' WITH GRANT OPTION;   #授权新用户
#flush privileges;    #刷新权限

最后就是注释的几个 启动mysql  登录mysql  授权就可以了
