Mysql绿色版安装

 适用于绿色版Mysql(编译安装后的Mysql)向其他机器复制安装,将脚本放在mysql目录中执行即可安装

#!/bin/bash
mysqluser=mysql
mysqldata=/data/mysql
mysqldir=$(cd `dirname $0`; pwd)



path=$(cd `dirname $0`; pwd)
#添加mysql用户
/usr/sbin/useradd $mysqluser -s /sbin/nologin
if [ ! -d $mysqldata ];then
	mkdir -p $mysqldata/data
	mkdir -p $mysqldata/logs
fi
chown $mysqluser:$mysqluser $mysqldata -R
chown $mysqluser:$mysqluser $mysqldir -R
#编辑配置文件
#cp ${path}/my.cnf /etc/my.cnf

cp ${path}/support-files/my-innodb-heavy-4G.cnf /etc/my.cnf
sed -i "/\[mysqld\]/ a \pid-file=${mysqldata}\/mysql.pid" /etc/my.cnf
sed -i "/pid-file=.*/ a \basedir=${mysqldir}" /etc/my.cnf
sed -i "/basedir=.*/ a \datadir=${mysqldata}\/data" /etc/my.cnf
sed -i "/datadir=.*/ a \log-error=${mysqldata}\/logs/error.log" /etc/my.cnf


cp ${path}/support-files/mysql.server /etc/init.d/mysqld
#sed -i "0,/basedir=/ s:basedir=:basedir=${mysqldir}:" /etc/init.d/mysqld
#sed -i "0,/basedir=/ s:datadir=:datadir=${mysqldata}\/data:" /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
#初始化mysql
echo "开始初始化mysql。。。"
${path}/scripts/mysql_install_db --user=$mysqluser --datadir=${mysqldata}/data/ --basedir=${mysqldir} >> /dev/null 2>&1
if [ $? -eq 0 ];then
        echo "mysql初始化完成！！！"

绿色版mysql配置主从同步(基本配置)
