修改 $1 -a 安裝 adb access ech and down 基於二進制安裝的mariadb實現多實例
1、mariadb版本：10.2.23
2、二進制安裝mariadb的shell腳本
#!/bin/bash id mysql &>/dev/null if [ `echo $?` -ne 0 ];then userdel -r mysql &>/dev/null useradd -r -u 336 -s /sbin/nologin -d /data/mysql mysql &>/dev/null else useradd -r -u 336 -s /sbin/nologin -d /data/mysql mysql &>/dev/null fi rpm -q libaio &>/dev/null [ `echo $?` -ne 0 ] && yum -y install libaio rpm -q expect &>/dev/null [ `echo $?` -ne 0 ] && yum -y install expect if [ -e mariadb-10.2.23-linux-x86_64.tar.gz ];then #此文件可能會造成影響，所以先清空 > /etc/my.cnf tar xf mariadb-10.2.23-linux-x86_64.tar.gz -C /usr/local/ cd /usr/local/ ln -s mariadb-10.2.23-linux-x86_64/ mysql chown -R root.root /usr/local/mysql/ echo ‘PATH=/usr/local/mysql/bin:$PATH‘ >/etc/profile.d/mysql.sh mkdir /data/mysql -p chown mysql.mysql /data/mysql/ cd /usr/local/mysql ./scripts/mysql_install_db --datadir=/data/mysql --user=mysql mkdir -p /etc/mysql cp /usr/local/mysql/support-files/my-huge.cnf /etc/mysql/my.cnf #禁止主機名解析，建議使用 sed -ri ‘/^\[mysqld\]/askip_name_resolve = on‘ /etc/mysql/my.cnf sed -ri ‘/^\[mysqld\]/adatadir=\/data\/mysql‘ /etc/mysql/my.cnf cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld chkconfig --add mysqld service mysqld start expect <<EOF spawn mysql_secure_installation expect { "Enter current password for root" { send "\n";exp_continue } "Set root password" { send "\n";exp_continue } "New password" { send "123456\n";exp_continue } "Re-enter new password" { send "123456\n";exp_continue } "Remove anonymous users" { send "y\n";exp_continue } "Disallow root login remotely" { send "y\n";exp_continue } "Remove test database and access to it" { send "y\n";exp_continue } "Reload privilege tables now" { send "y\n" } } #expect "]#" { send "exit\n" } expect eof EOF mysqladmin -uroot -p123456 ping &>/dev/null [ `echo $?` -eq 0 ] && echo ‘mysql is running !‘ || echo ‘mysql is stopped‘ else echo -e "mariadb-10.2.23-linux-x86_64.tar.gz is not exist" exit fi
3、實現多示例
1、創建多實例對應的目錄結構
mkdir -p /mysql/{3306,3307,3308}/{data,etc,socket,log,bin,pid}
chown -R mysql.mysql /mysql/
2、創建多實例的數據庫文件
/usr/local/mysql/scripts/mysql_install_db --datadir=/mysql/3306/data/ --user=mysql /usr/local/mysql/scripts/mysql_install_db --datadir=/mysql/3307/data/ --user=mysql /usr/local/mysql/scripts/mysql_install_db --datadir=/mysql/3308/data/ --user=mysql
3、創建對應配置文件
cp /etc/mysql/my.cnf /mysql/3306/etc/ vim /mysql/3306/etc/my.cnf [mysqld] port=3306 加一行 datadir=/mysql/3306/data socket=/mysql/3306/socket/mysql.sock [mysqld_safe] log-error=/mysql/3306/log/mariadb.log pid-file=/mysql/3306/pid/mariadb.pid #3307和3308同步修改 cp /mysql/3306/etc/my.cnf /mysql/3307/etc/my.cnf /mysql/3307/etc/my.cnf 修改 cp /mysql/3306/etc/my.cnf /mysql/3308/etc/my.cnf /mysql/3308/etc/my.cnf 修改
4、準備各實例的啟動腳本並添加執行權限
vi /mysql/{3306,3307,3308}/bin/mysqld
cat /mysql/3306/bin/mysqld
#!/bin/bash
port=3306
mysql_user="root"
mysql_pwd="123456"
#cmd_path="/mysql/3306/bin"
cmd_path="/usr/local/mariadb-10.2.23-linux-x86_64/bin"
mysql_basedir="/mysql"
mysql_sock="${mysql_basedir}/${port}/socket/mysql.sock"
function_start_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "Starting MySQL...\n"
${cmd_path}/mysqld_safe --defaults-file=${mysql_basedir}/${port}/etc/my.cnf &> /dev/null &
else
printf "MySQL is running...\n"
exit
fi
}
function_stop_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "MySQL is stopped...\n"
exit
else
printf "Stoping MySQL...\n"
${cmd_path}/mysqladmin -u ${mysql_user} -p${mysql_pwd} -S ${mysql_sock} shutdown
fi
}
function_restart_mysql()
{
printf "Restarting MySQL...\n"
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: ${mysql_basedir}/${port}/bin/mysqld {start|stop|restart}\n"
esac
#添加執行權限
chmod +x /mysql/{3306,3307,3308}/bin/mysqld
5、啟動服務並做安全加固（如果不做安全加固，則stop時的腳本有問題，密碼不正確）
/mysql/{3306,3307,3308}/bin/mysqld start
#安全加固
/usr/local/mysql/bin/mysql_secure_installation -S /mysql/{3306,3307,3308}/socket/mysql.sock （輸入的密碼與啟動腳本一致）
6、測試連接
mysql -uroot -p123456 -S /mysql/{3306,3307,3308}/socket/mysql.sock基於二進制安裝的mariadb實現多實例
