# Desc: install mysql5.7.44
#
echo "******** INSTALL MYSQL *********"

BASEDIR=$(cd "$(dirname "$0")"; pwd)

# 卸载原有的mariadb
OLD_MYSQL=`rpm -qa|grep mariadb`
profile=/etc/profile
for mariadb in $OLD_MYSQL
do
	rpm -e --nodeps $mariadb
done

# 删除原有的my.cnf
rm -rf /etc/my.cnf

#添加用户组 用户
groupadd mysql
useradd -g mysql mysql

#解压mysql包并修改名称
tar -zxvf  $BASEDIR/mysql-5.7.44-el7-x86_64.tar.gz -C /usr/local
mv /usr/local/mysql-5.7.44-el7-x86_64 /usr/local/mysql

#更改所属的组和用户
chown -R mysql /usr/local/mysql
chgrp -R mysql /usr/local/mysql

mkdir -p /usr/local/mysql/data
mkdir -p /usr/local/mysql/log
chown -R mysql:mysql /usr/local/mysql/data

#粘贴配置文件my.cnf 内容见八 中的 my.cnf
cp $BASEDIR/config/my.cnf /usr/local/mysql/

# 安装mysql
/usr/local/mysql/bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/

# 设置文件及目录权限：
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

# 启动mysql
/etc/init.d/mysqld start

# 设置开机启动
chkconfig --level 35 mysqld on
chmod +x /etc/rc.d/init.d/mysqld
chkconfig --add mysqld

# 修改环境变量 
ln -s /usr/local/mysql/bin/mysql /usr/bin
