安装Go语言环境（Go版本1.3以上）

git clone https://github.com/flike/kingshard.git src/github.com/flike/kingshard

cd src/github.com/flike/kingshard

source ./dev.sh

make

设置配置文件

./bin/kingshard -config=etc/ks.yaml

./bin/kingshard -config=etc/ks.yaml –fork 后台运行

开启多mysql实例

Create the file mysqld@.service in the /etc/systemd/system/

[Unit]
Description=MySQL Multi Server for instance %i
After=syslog.target
After=network.target

[Service]
User=mysql
Group=mysql
Type=forking
ExecStart=/usr/bin/mysqld_multi start %i

/etc/my.cnf

[mysqld_multi]
mysqld = /usr/bin/mysqld_safe --basedir=/usr

[mysqld1]
port=63132
datadir=/var/lib/mysql/1/
socket=/var/lib/mysql/1/mysql.sock
pid-file=/var/run/mysqld/mysqld1.pid

log-error=/var/log/mysqld1.log
# Disabling symbolic-links is recommended to prevent assorted security
# risks
symbolic-links=0

[mysqld2]
port=63133
datadir=/var/lib/mysql/2/

pid-file=/var/run/mysqld/mysqld2.pid

log-error=/var/log/mysqld2.log

# Disabling symbolic-links is recommended to prevent assorted security
# risks
symbolic-links=0

Create data directories for each instance:

# mkdir /var/lib/mysql/{1,2}

# chcon --reference=/var/lib/mysql/ /target/directory

Create a log file for each instance and give it the correct permissions and security context:

# touch /var/log/mysqld{1,2}.log
# chmod o-r mysqld{1,2}.log  这个重要的，-R 777
# chcon --reference=/var/log/mysqld.log /var/log/mysqld{1,2}.log

Initialize mysql databases:

# mysql_install_db --user=mysql --datadir=/var/lib/mysql/1/
# mysql_install_db --user=mysql --datadir=/var/lib/mysql/2/

Start mysqld instances:

# systemctl start mysqld@1
# systemctl start mysqld@2

Check the logs to make sure everything is running okay:

# systemctl status mysqld@1
# systemctl status mysqld@2
# cat /var/log/mysqld.log
# cat /var/log/mysqld1.log
# cat /var/log/mysqld2.log

Enable services at startup.

# systemctl enable mysqld@1
# systemctl enable mysqld@2
