mysql数据库多实例部署
本文系统：rhel5.8
ip : 192.168.100.150
数据库版本：mysql-5.6.15
1、创建部署mysql服务账号：
[root@daf ~]# useradd -d /opt/mysql mysql [root@daf ~]# echo "mysql" |passwd --stdin mysql Changing password for user mysql. passwd: all authentication tokens updated successfully.
2、解压无需免装包：配置环境变量
[mysql@daf ~]$ tar zxvf mysql-5.6.15-linux-glibc2.5-x86_64.tar.gz [mysql@daf ~]$ mv mysql-5.6.15-linux-glibc2.5-x86_64 mysql-5.6.15 [mysql@daf mysql-5.6.15]$ vim ~/.bash_profile MYSQL_HOME=/opt/mysql/mysql-5.6.15 export MYSQL_HOME PATH=$MYSQL_HOME/bin:$PATH export PATH
3、配置多实例数据库配置文件
[root@daf ~]# mkdir /Data_for_Mysql [root@daf ~]# chown mysql.mysql -R /Data_for_Mysql/ [root@daf ~]# su - mysql [mysql@daf ~]$ mkdir -p /Data_for_Mysql/3301/data /Data_for_Mysql/3301/logs [mysql@daf ~]$ touch /Data_for_Mysql/3301/my.cnf [mysql@daf ~]$ mkdir -p /Data_for_Mysql/3302/data /Data_for_Mysql/3302/logs [mysql@daf ~]$ touch /Data_for_Mysql/3302/my.cnf
目录结构：
[mysql@daf Data_for_Mysql]$ pwd /Data_for_Mysql [mysql@daf Data_for_Mysql]$ tree . |-- 3301 | |-- data | |-- logs | `-- my.cnf `-- 3302 |-- data |-- logs `-- my.cnf 6 directories, 2 files [mysql@daf Data_for_Mysql]$
配置my.cnf ######本配置文件只供参考
[mysql@daf 3301]$ vim /Data_for_Mysql/3301/my.cnf [client] port = 3301 socket = /Data_for_Mysql/3301/data/mysql.sock [mysqld] user=msql port=3301 bind-address=192.168.100.150 socket = /Data_for_Mysql/3301/data/mysql.sock.3301 pid-file = /Data_for_Mysql/3301/data/mysql.pid basedir = /opt/mysql/mysql-5.6.15 datadir = /Data_for_Mysql/3301/data server-id=1 log-bin=mysql-bin log-bin-index= mysql-bin.index # LOGGING log_error=/Data_for_Mysql/3301/logs/mysql-error.log slow_query_log_file= /Data_for_Mysql/3301/logs/mysql-slow.log slow_query_log=1 character-sets-dir = /opt/mysql/mysql-5.6.15/share/charsets back_log = 2000 max_connections = 1000 connect-timeout = 60 wait-timeout = 28800 net_buffer_length = 16384 max_allowed_packet = 64M thread_stack = 192K thread_cache_size = 20 thread_concurrency = 128 query_cache_size = 256M query_cache_limit = 2M query_cache_min_res_unit = 2 default-time-zone = system character-set-server = utf8 default-storage-engine = InnoDB tmp_table_size = 512M max_heap_table_size = 512M max_binlog_size = 1G max_relay_log_size = 1G [mysql] disable-auto-rehash default-character-set = utf8
4、初始化数据库
[mysql@daf scripts]$ pwd /opt/mysql/mysql-5.6.15/scripts [mysql@daf scripts]$ ./mysql_install_db --defaults-file=/Data_for_Mysql/3301/my.cnf --user=mysql --basedir=/opt/mysql/mysql-5.6.15 --datadir=/Data_for_Mysql/3301/data/
5、启动3301实例数据库 ###启动数据库必须在mysql目录；
[mysql@daf mysql-5.6.15]$ pwd /opt/mysql/mysql-5.6.15 [mysql@daf mysql-5.6.15]$ mysqld_safe --defaults-file=/Data_for_Mysql/3301/my.cnf --user=mysql --basedir=/opt/mysql/mysql-5.6.15 --datadir=/Data_for_Mysql/3301/data/ & [mysql@daf mysql-5.6.15]$ netstat -nat |grep 3301 tcp 0 0 192.168.100.150:3301 0.0.0.0:* LISTEN
Ps:3302 实例操作和上面一样，只需改动端口及相应目录即可；
3302配置文件：
[mysql@daf 3302]$ cat my.cnf [client] port = 3302 socket = /Data_for_Mysql/3302/data/mysql.sock [mysqld] user=mysql port=3302 bind-address=192.168.100.150 socket = /Data_for_Mysql/3302/data/mysql.sock.3302 pid-file = /Data_for_Mysql/3302/data/mysql.pid basedir = /opt/mysql/mysql-5.6.15 datadir = /Data_for_Mysql/3302/data server-id=1 log-bin=mysql-bin log-bin-index= mysql-bin.index # LOGGING log_error=/Data_for_Mysql/3302/logs/mysql-error.log slow_query_log_file= /Data_for_Mysql/3302/logs/mysql-slow.log slow_query_log=1 character-sets-dir = /opt/mysql/mysql-5.6.15/share/charsets back_log = 2000 max_connections = 1000 connect-timeout = 60 wait-timeout = 28800 net_buffer_length = 16384 max_allowed_packet = 64M thread_stack = 192K thread_cache_size = 20 thread_concurrency = 128 query_cache_size = 256M query_cache_limit = 2M query_cache_min_res_unit = 2 default-time-zone = system character-set-server = utf8 default-storage-engine = InnoDB tmp_table_size = 512M max_heap_table_size = 512M max_binlog_size = 1G max_relay_log_size = 1G [mysql] disable-auto-rehash default-character-set = utf8
3302 实例初始化；
[mysql@daf scripts]$ pwd /opt/mysql/mysql-5.6.15/scripts [mysql@daf scripts]$ ./mysql_install_db --defaults-file=/Data_for_Mysql/3302/my.cnf --user=mysql --basedir=/opt/mysql/mysql-5.6.15 --datadir=/Data_for_Mysql/3302/data/
3302 启动该实例：
[mysql@daf mysql-5.6.15]$ mysqld_safe --defaults-file=/Data_for_Mysql/3302/my.cnf --user=mysql --basedir=/opt/mysql/mysql-5.6.15 --datadir=/Data_for_Mysql/3302/data/ & [mysql@daf mysql-5.6.15]$ netstat -nat |grep 330 tcp 0 0 192.168.100.150:3301 0.0.0.0:* LISTEN tcp 0 0 192.168.100.150:3302 0.0.0.0:* LISTEN
6、创建root密码，要区别实例
[mysql@daf mysql-5.6.15]$ mysqladmin -uroot password 'root123' -S /Data_for_Mysql/3301/data/mysql.sock.3301
6.1、关闭mysql，区别实例
[mysql@daf mysql-5.6.15]$ mysqladmin -uroot -proot123 -S /Data_for_Mysql/3301/data/mysql.sock.3301 shutdown Warning: Using a password on the command line interface can be insecure. 150402 15:44:52 mysqld_safe mysqld from pid file /Data_for_Mysql/3301/data/mysql.pid ended [1]- Done mysqld_safe --defaults-file=/Data_for_Mysql/3301/my.cnf --user=mysql --basedir=/opt/mysql/mysql-5.6.15 --datadir=/Data_for_Mysql/3301/data/
