mysql自动安装脚本
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：shmysql_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 tmpetc
#chown mysql:mysqldata log tmp etc
####2.安装mysql####
cd $mk_mysqldir
tar -xzfmysql-5.6.16.tar.gz
cd mysql-5.6.16
##cmake install##
cmake\
-DCMAKE_INSTALL_PREFIX=${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#####

####4.初始化数据库并启动####
cd$mysql_dir/scripts
./mysql_install_db--basedir=$mysql_dir --datadir=$mysql_dir/data --user=root
cd $mysql_dir/bin
./mysqld_safe--defaults-file=$mysql_dir/etc/my.cnf --user=root &
####5.添加mysql命令到环境变量中####
echo "exportPATH=$mysql_dir/bin:$PATH" >>/root/.bash_profile
source/root/.bash_profile
