centos6多实例安装mysql

基本环境：
setenforce 0
service iptables stop

yum install cmake libaio-devel ncurses-devel -y
yum install gcc gcc-c++ -y
yum install cmake -y
useradd mysql -s /sbin/nologin -M -g mysql

下载：
cd /application/
wget https://downloads.mysql.com/archives/get/file/mysql-5.5.33.tar.gz
tar -zxvf mysql-5.5.33.tar.gz
cd /application/mysql-5.5.33

开始编译：
#cmake . -DCMAKE_INSTALL_PREFIX=/application/mysql-5.5.33

-DMYSQL_DATADIR=/application/mysql-5.5.33/data

-DMYSQL_UNIX_ADDR=/application/mysql-5.5.33/tmp/mysql.sock

-DDEFAULT_CHARSET=utf8

-DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=gbk,gb2312,utf8,ascii

-DENABLED_LOCAL_INFILE=ON -DWITH_INNOBASE_STORAGE_ENGINE=1

-DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1

-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 -DWITHOUT_PARTITION_STORAGE_ENGINE=1

-DWITH_ZLIB=bundled -DENABLED_LOCAL_INFILE=1

-DWITH_READLINE=1

-DWITH_EMBEDDED_SERVER=1

-DWITH_DEBUG=0

#make && make install
#ln -s /application/mysql-5.5.33/ /application/mysql

编译成功
若编译过程中出现报错，则一定要先删除
[root@mysql mysql-5.5.32]# rm CMakeCache.txt ###删除这个文件，重新cmake

创建各实例的数据文件目录：
#mkdir -p /data/{3306,3307}/data
#tree /data/
/data/

创建启动文件：

3306的：

#init

mysql_user="root"

CmdPath="/application/mysql/bin"
function_start_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "Starting MySQL... "
else
printf "MySQL is running... "
exit
fi
}

#stop function
function_stop_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "MySQL is stopped... "
exit
else
printf "Stoping MySQL... "
fi
}

#restart function
function_restart_mysql()
{
printf "Restarting MySQL... "
function_stop_mysql
sleep 2
function_start_mysql
}

case $1 in
start)
function_start_mysql
;;
stop)
function_stop_mysql
;;
restart)
function_restart_mysql
;;
*)
printf "Usage: /data/${port}/mysql {start|stop|restart} "
esac

3307的:

#init

port=3307
mysql_user="root"
mysql_pwd="123.asd"
CmdPath="/application/mysql/bin"
function_start_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "Starting MySQL... "
else
printf "MySQL is running... "
exit
fi
}

#stop function
function_stop_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "MySQL is stopped... "
exit
else
printf "Stoping MySQL... "
fi
}

#restart function
function_restart_mysql()
{
printf "Restarting MySQL... "
function_stop_mysql
sleep 2
function_start_mysql
}

case $1 in
start)
function_start_mysql
;;
stop)
function_stop_mysql
;;
restart)
function_restart_mysql
;;
*)
printf "Usage: /data/${port}/mysql {start|stop|restart} "
esac

目录结构如下：
[root@centos6 /data ]#tree
.
├── 3306
│   ├── data
│   ├── my.cnf
│   └── mysql
└── 3307
├── data
├── my.cnf
└── mysql

给启动文件执行权限：

[root@centos6 / ]#find /data -type f -name "mysql"
/data/3306/mysql
/data/3307/mysql
[root@centos6 / ]#find /data -type f -name "mysql" |xargs chmod +x
[root@centos6 / ]#find /data -type f -name "mysql" |xargs ls -l
-rwxr-xr-x. 1 root root 762 Jul 6 16:15 /data/3306/mysql
-rwxr-xr-x. 1 root root 762 Jul 6 16:16 /data/3307/mysql

让mysql用户管理data目录：

[root@centos6 / ]#chown -R mysql.mysql /data/

初始化：

#cd /application/mysql/scripts/

./mysql_install_db --basedir=/application/mysql --datadir=/data/3306/data --user=mysql

./mysql_install_db --basedir=/application/mysql --datadir=/data/3307/data --user=mysql

报错-bash: scripts/mysql_install_db: Permission denied则：修改mysql_install_db的权限，可能该文件没有执行权限
