为适应自己工作习惯和需要，花一点时间写了一个mysql自动安装脚本，供大家参考学习。

注意：

1、需要先安装cmake

2、数据库版本需要在第二步安装mysql时修改

3、该脚本是以root用户安装并启动

脚本内容如下：

########################################################################

#mysql自动安装脚本，其中变量/mysql_v_dir/和/port/可根据实际需要修改    #

#执行脚本命令：sh mysql_install.sh >mysql_install.log                  #

########################################################################

####0.定义mysql目录####

mk_mysqldir=/tmp/setup                ##mysql安装包所在目录

mysql_v_dir=mysql_5611                ##mysql version directry

mysql_dir=/home/mysql/$mysql_v_dir    ##the path where mysql install

port=5611                             ##端口号

####1.创建mysql用户和组####

#user=`cat /etc/passwd |grep mysql`

#if [ -z $user ]

#then

#groupadd mysql

#useradd mysql -d /home/mysql -g mysql

#else

#userdel mysql

#groupdel mysql

#groupadd mysql

#useradd mysql -d /home/mysql -g mysql

#fi

cd /home/mysql

mkdir $mysql_v_dir

cd $mysql_dir

mkdir data log tmp etc

#chown mysql:mysql data log tmp etc

####2.安装mysql####

cd $mk_mysqldir

tar -xzf mysql-5.6.16.tar.gz

cd mysql-5.6.16

##cmake install##

cmake  \

-DCMAKE_INSTALL_PREFIX=${mysql_dir}  \

-DINSTALL_MYSQLDATADIR=${mysql_dir}/data  \

-DMYSQL_DATADIR=${mysql_dir}/data \

-DSYSCONFDIR=${mysql_dir}/etc    \

-DWITH_INNOBASE_STORAGE_ENGINE=1  \

-DDEFAULT_CHARSET=utf8   \

-DDEFAULT_COLLATION=utf8_general_ci  \

-DMYSQL_TCP_PORT=5535  \

-DMYSQL_UNIX_ADDR=${mysql_dir}/tmp/mysql.sock  \

-DWITH_EXTRA_CHARSETS=all

make ; make install

####3.创建并修改配置文件#####
