mysql版本号：mysql-5.5.32
1）安装mysql所需的依赖包
# adduser mysql -s /sbin/nologin -M
# mkdir -p /data/{3306,3307}/data
# tree /data/
/data/
├── 3306
│?? └── data
└── 3307
└── data
4 directories, 0 files
# yum -y install ncurse-devel libaio-devel
2）安装编译mysql需要的软件
# tar xf cmake-2.8.8.tar.gz # cd cmake-2.8.8 # ./configure # gmake # which cmake /usr/bin/cmake
3）采用编译安装mysql
# ls -l |grep mysql -rw-r--r-- 1 root root 186722932 6月 27 05:03 mysql-5.5.32-linux2.6-x86_64.tar.gz -rw-r--r-- 1 root root 24596474 6月 27 05:10 mysql-5.5.32.tar.gz 说明：mysql-5.5.32-linux2.6-x86_64.tar.gz为二进制安装包、mysql-5.5.32.tar.gz为源码安装包 # tar xf mysql-5.5.32.tar.gz # cd mysql-5.5.32 # cmake . -DCMAKE_INSTALL_PREFIX=/application/mysql-5.5.32 \ -DMYSQL_DATADIR=/application/mysql-5.5.32/data \ -DMYSQL_UNIX_ADDR=/application/mysql-5.5.32/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_FAST_MUTEXES=1 \ -DWITH_ZLIB=bundled \ -DENABLED_LOCAL_INFILE=1 \ -DWITH_READLINE=1 \ -DWITH_EMBEDDED_SERVER=1 \ -DWITH_DEBUG=0 # make # make install
4）创建mysql多实例的数据文件目录
# mkdir -p /data/{3306,3307}/data
# tree /data
# ln -s /application/mysql-5.5.32/ /application/mysql
# ll /application/mysql
lrwxrwxrwx 1 root root 26 10月 8 22:50 /application/mysql -> /application/mysql-5.5.32/
# cd /data/3306
# ls -lrt
总用量 12
drwxr-xr-x 2 root root 4096 10月 8 21:13 data
-rw-r--r-- 1 root root 1899 10月 29 2013 my.cnf
-rw-r--r-- 1 root root 1307 7月 15 2013 mysql
5）编辑mysql实例配置文件
a、创建3306实例配置文件
# vim /data/3306/my.cnf [client] port = 3306 socket = /data/3306/mysql.sock [mysql] no-auto-rehash [mysqld] user = mysql port = 3306 socket = /data/3306/mysql.sock basedir = /application/mysql datadir = /data/3306/data open_files_limit = 1024 back_log = 600 max_connections = 800 max_connect_errors = 3000 table_cache = 614 external-locking = FALSE max_allowed_packet =8M sort_buffer_size = 1M join_buffer_size = 1M thread_cache_size = 100 thread_concurrency = 2 query_cache_size = 2M query_cache_limit = 1M query_cache_min_res_unit = 2k #default_table_type = InnoDB thread_stack = 192K #transaction_isolation = READ-COMMITTED tmp_table_size = 2M max_heap_table_size = 2M long_query_time = 1 #log_long_format #log-error = /data/3306/error.log #log-slow-queries = /data/3306/slow.log pid-file = /data/3306/mysql.pid log-bin = /data/3306/mysql-bin relay-log = /data/3306/relay-bin relay-log-info-file = /data/3306/relay-log.info binlog_cache_size = 1M max_binlog_cache_size = 1M max_binlog_size = 2M expire_logs_days = 7 key_buffer_size = 16M read_buffer_size = 1M read_rnd_buffer_size = 1M bulk_insert_buffer_size = 1M #myisam_sort_buffer_size = 1M #myisam_max_sort_file_size = 10G #myisam_max_extra_sort_file_size = 10G #myisam_repair_threads = 1 #myisam_recover lower_case_table_names = 1 skip-name-resolve slave-skip-errors = 1032,1062 replicate-ignore-db=mysql server-id = 1 innodb_additional_mem_pool_size = 4M innodb_buffer_pool_size = 32M innodb_data_file_path = ibdata1:128M:autoextend innodb_file_io_threads = 4 innodb_thread_concurrency = 8 innodb_flush_log_at_trx_commit = 2 innodb_log_buffer_size = 2M innodb_log_file_size = 4M innodb_log_files_in_group = 3 innodb_max_dirty_pages_pct = 90 innodb_lock_wait_timeout = 120 innodb_file_per_table = 0 [mysqldump] quick max_allowed_packet = 2M [mysqld_safe] log-error=/data/3306/mysql_oldboy3306.err pid-file=/data/3306/mysqld.pid
b、创建3306实例启动脚本
# vim /data/3306/mysql
#!/bin/sh
#init
port=3306
mysql_user="root"
mysql_pwd="redhat12345"
CmdPath="/application/mysql/bin"
mysql_sock="/data/${port}/mysql.sock"
#startup function
function_start_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "Starting MySQL...\n"
/bin/sh ${CmdPath}/mysqld_safe --defaults-file=/data/${port}/my.cnf 2>&1 > /dev/null &
else
printf "MySQL is running...\n"
exit
fi
}
#stop function
function_stop_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "MySQL is stopped...\n"
exit
else
printf "Stoping MySQL...\n"
${CmdPath}/mysqladmin -u ${mysql_user} -p${mysql_pwd} -S /data/${port}/mysql.sock shutdown
fi
}
#restart function
function_restart_mysql()
{
printf "Restarting MySQL...\n"
function_stop_mysql
sleep 2
function_start_mysql
}
case $1 in
start)
function_start_mysql
;;
stop)
function_stop_mysql
;;
restart)
function_restart_mysql
;;
*)
printf "Usage: /data/${port}/mysql {start|stop|restart}\n"
esac
c、创建3307实例配置文件
# vim /data/3307/my.cnf [client] port = 3307 socket = /data/3307/mysql.sock [mysql] no-auto-rehash [mysqld] user = mysql port = 3307 socket = /data/3307/mysql.sock basedir = /application/mysql datadir = /data/3307/data open_files_limit = 1024 back_log = 600 max_connections = 800 max_connect_errors = 3000 table_cache = 614 external-locking = FALSE max_allowed_packet =8M sort_buffer_size = 1M join_buffer_size = 1M thread_cache_size = 100 thread_concurrency = 2 query_cache_size = 2M query_cache_limit = 1M query_cache_min_res_unit = 2k #default_table_type = InnoDB thread_stack = 192K #transaction_isolation = READ-COMMITTED tmp_table_size = 2M max_heap_table_size = 2M #long_query_time = 1 #log_long_format #log-error = /data/3307/error.log #log-slow-queries = /data/3307/slow.log pid-file = /data/3307/mysql.pid #log-bin = /data/3307/mysql-bin relay-log = /data/3307/relay-bin relay-log-info-file = /data/3307/relay-log.info binlog_cache_size = 1M max_binlog_cache_size = 1M max_binlog_size = 2M expire_logs_days = 7 key_buffer_size = 16M read_buffer_size = 1M read_rnd_buffer_size = 1M bulk_insert_buffer_size = 1M #myisam_sort_buffer_size = 1M #myisam_max_sort_file_size = 10G #myisam_max_extra_sort_file_size = 10G #myisam_repair_threads = 1 #myisam_recover lower_case_table_names = 1 skip-name-resolve slave-skip-errors = 1032,1062 replicate-ignore-db=mysql server-id = 3 innodb_additional_mem_pool_size = 4M innodb_buffer_pool_size = 32M innodb_data_file_path = ibdata1:128M:autoextend innodb_file_io_threads = 4 innodb_thread_concurrency = 8 innodb_flush_log_at_trx_commit = 2 innodb_log_buffer_size = 2M innodb_log_file_size = 4M innodb_log_files_in_group = 3 innodb_max_dirty_pages_pct = 90 innodb_lock_wait_timeout = 120 innodb_file_per_table = 0 [mysqldump] quick max_allowed_packet = 2M [mysqld_safe] log-error=/data/3307/mysql_oldboy3307.err pid-file=/data/3307/mysqld.pid
d、创建3307实例启动脚本
#!/bin/sh
#init
port=3307
mysql_user="root"
mysql_pwd="redhat12345"
CmdPath="/application/mysql/bin"
mysql_sock="/data/${port}/mysql.sock"
#startup function
function_start_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "Starting MySQL...\n"
/bin/sh ${CmdPath}/mysqld_safe --defaults-file=/data/${port}/my.cnf 2>&1 > /dev/null &
else
printf "MySQL is running...\n"
exit
fi
}
#stop function
function_stop_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "MySQL is stopped...\n"
exit
else
printf "Stoping MySQL...\n"
${CmdPath}/mysqladmin -u ${mysql_user} -p${mysql_pwd} -S /data/${port}/mysql.sock shutdown
fi
}
#restart function
function_restart_mysql()
{
printf "Restarting MySQL...\n"
function_stop_mysql
sleep 2
function_start_mysql
}
case $1 in
start)
function_start_mysql
;;
stop)
function_stop_mysql
;;
restart)
function_restart_mysql
;;
*)
printf "Usage: /data/${port}/mysql {start|stop|restart}\n"
esac
6）配置mysql多实例的文件权限
# chown -R mysql.mysql /data # find /data -name mysql|xargs ls -l -rw-r--r-- 1 mysql mysql 1312 10月 8 23:03 /data/3306/mysql -rw-r--r-- 1 mysql mysql 1312 10月 8 23:03 /data/3307/mysql # find /data -name mysql|xargs chmod 700 # find /data -name mysql|xargs ls -l -rwx------ 1 mysql mysql 1312 10月 8 23:03 /data/3306/mysql -rwx------ 1 mysql mysql 1312 10月 8 23:03 /data/3307/mysql
7）将mysql相关命令加入全局路径
# ls /application/mysql/bin/mysql /application/mysql/bin/mysql # echo 'export PATH=/application/mysql/bin:$PATH'>>/etc/profile # tail -1 /etc/profile export PATH=/application/mysql/bin:$PATH # source /etc/profile # echo $PATH /application/mysql/bin:/application/mysql/bin/:/application/nginx/sbin/:/application/mysql/bin/:/application/nginx/sbin/:/usr/lib64/qt-3.3/bin:/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
8）初始化实例的数据库文件
# ./mysql_install_db --basedir=/application/mysql --datadir=/data/3306/data --user=mysql # ./mysql_install_db --basedir=/application/mysql --datadir=/data/3307/data --user=mysql # echo $? 0
# 启动多实例
# /data/3306/mysql start Starting MySQL... # /data/3307/mysql start Starting MySQL...
# 查看数据库是否启动
# netstat -tunlp | grep 330* tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 28533/mysqld tcp 0 0 0.0.0.0:3307 0.0.0.0:* LISTEN 29250/mysqld
# 配置mysql多实例数据库开机自启动
# echo "# mysql multi instances startup">>/etc/rc.local # echo "/data/3306/mysql start">>/etc/rc.local # echo "/data/3307/mysql start">>/etc/rc.local
# 登录mysql进行测试：
# mysql -S /data/3306/mysql.sock # mysql -S /data/3307/mysql.sock
9) mysql安全设置
# mysqladmin -u root -S /data/3306/mysql.sock password 'redhat12345' # mysqladmin -u root -S /data/3307/mysql.sock password 'redhat12345'
10) 登录进入mysql
# mysql -uroot -S /data/3306/mysql.sock -p
Enter password:

-rwx------ 1 root root 1312 10月 8 23:03 /data/3307/mysql
11) mysql的启停测试
# /data/3306/mysql stop Stoping MySQL... # netstat -tunlp | grep 330* tcp 0 0 0.0.0.0:3307 0.0.0.0:* LISTEN 29250/mysqld # /data/3306/mysql start Starting MySQL... # netstat -tunlp | grep 330* tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 30168/mysqld tcp 0 0 0.0.0.0:3307 0.0.0.0:* LISTEN 29250/mysqld
12) 在远程主机进行测试
a、服务器端创建数据库并添加授权账号 mysql> create database wanlong; Query OK, 1 row affected (0.00 sec) mysql> create user wan identified by "redhat"; Query OK, 0 rows affected (0.00 sec) mysql> grant all privileges on wanlong.* to 'wan'@'10.10.10.%' identified by 'redhat' with grant option; Query OK, 0 rows affected (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | test | | wanlong | +--------------------+ 5 rows in set (0.00 sec)
b、客户端进行访问：
# mysql -uwan -predhat -h 10.10.10.129 -u：用户名 -p：密码 -h：远程主机 mysql> select user(); +------------------+ | user() | +------------------+ | wan@10.10.10.130 | +------------------+ 1 row in set (0.00 sec) mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | test | | wanlong | +--------------------+ 3 rows in set (0.01 sec)
到此，mysql的多实例已经完成
