mysql服务搭建 mysql

mysql服务搭建
【mysql服务搭建】操作系统 ContOS 6.9
1.下载、解压

下载

# wget https://downloads.mariadb.org/f/mariadb-10.1.25/bintar-linux-x86_64/mariadb-10.1.25-linux-x86_64.tar.gz

解压

# tar -zxvf ./mariadb-10.1.25-linux-x86_64.tar.gz # mv ./mariadb-10.1.25-linux-x86_64/usr/local/mysql

2.安装

安装必要的组件

# yum install –y autoconf automake imake libxml2-devel expat-devel cmake gcc gcc-c++ libaio libaio-devel bzr bison libtool ncurses5-devel

3.创建mysql的用户组和用户

# groupadd mysql # useradd -g mysql mysql -M -s /sbin/nologin

4.修改my.cnf配置文件

# ple MySQL config file for large systems.# This is for a large system with memory = 512M where the system runs mainly # MySQL. # # MySQL programs look for option files in a set of # locations which depend on the deployment platform. # You can copy this option file to one of those # locations. For information about these locations, see: # http://dev.mysql.com/doc/mysql/en/option-files.html # # In this file, you can use all long options that a program supports. # If you want to know which options a program supports, run the program # with the "--help" option.# The following options will be passed to all MySQL clients [client] #password = your_password port = 3306 socket = /tmp/mysql.sock# Here follows entries for some specific programs# The MySQL server [mysqld] port = 3306 socket = /tmp/mysql.sock skip-external-locking key_buffer_size = 256M max_allowed_packet = 1M table_open_cache = 256 sort_buffer_size = 1M read_buffer_size = 1M read_rnd_buffer_size = 4M myisam_sort_buffer_size = 64M thread_cache_size = 8 query_cache_size= 16M # Try number of CPU's*2 for thread_concurrency thread_concurrency = 8datadir = /usr/local/mysql/data log-error = /usr/local/mysql/data/error.log pid-file = /usr/local/mysql/data/mysql.pid user = mysql tmpdir = /tmp# Don't listen on a TCP/IP port at all. This can be a security enhancement, # if all processes that need to connect to mysqld run on the same host. # All interaction with mysqld must be made via Unix sockets or named pipes. # Note that using this option without enabling named pipes on Windows # (via the "enable-named-pipe" option) will render mysqld useless! # #skip-networking# Replication Master Server (default) # binary logging is required for replication log-bin=mysql-bin# binary logging format - mixed recommended binlog_format=mixed# required unique id between 1 and 2^32 - 1 # defaults to 1 if master-host is not set # but will not function as a master if omitted server-id = 1# Replication Slave (comment out master section to use this) # # To configure this host as a replication slave, you can choose between # two methods : # # 1) Use the CHANGE MASTER TO command (fully described in our manual) - # the syntax is: # # CHANGE MASTER TO MASTER_HOST=, MASTER_PORT=, # MASTER_USER=, MASTER_PASSWORD= ; # # where you replace , , by quoted strings and # by the master's port number (3306 by default). # # Example: # # CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306, # MASTER_USER='joe', MASTER_PASSWORD='secret'; # # OR # # 2) Set the variables below. However, in case you choose this method, then # start replication for the first time (even unsuccessfully, for example # if you mistyped the password in master-password and the slave fails to # connect), the slave will create a master.info file, and any later # change in this file to the variables' values below will be ignored and # overridden by the content of the master.info file, unless you shutdown # the slave server, delete master.info and restart the slaver server. # For that reason, you may want to leave the lines below untouched # (commented) and instead use CHANGE MASTER TO (see above) # # required unique id between 2 and 2^32 - 1 # (and different from the master) # defaults to 2 if master-host is set # but will not function as a slave if omitted #server-id = 2 # # The replication master for this slave - required #master-host = # # The username the slave will use for authentication when connecting # to the master - required #master-user = # # The password the slave will authenticate with when connecting to # the master - required #master-password = # # The port the master is listening on. # optional - defaults to 3306 #master-port = # # binary logging - not required for slaves, but recommended #log-bin=mysql-bin# Uncomment the following if you are using InnoDB tables #innodb_data_home_dir = /usr/local/mysql/data #innodb_data_file_path = ibdata1:10M:autoextend #innodb_log_group_home_dir = /usr/local/mysql/data # You can set .._buffer_pool_size up to 50 - 80 % # of RAM but beware of setting memory usage too high #innodb_buffer_pool_size = 256M #innodb_additional_mem_pool_size = 20M # Set .._log_file_size to 25 % of buffer pool size #innodb_log_file_size = 64M #innodb_log_buffer_size = 8M #innodb_flush_log_at_trx_commit = 1 #innodb_lock_wait_timeout = 50[mysqldump] quick max_allowed_packet = 16M[mysql] no-auto-rehash # Remove the next comment character if you are not familiar with SQL #safe-updates[myisamchk] key_buffer_size = 128M sort_buffer_size = 128M read_buffer = 2M write_buffer = 2M[mysqlhotcopy] interactive-timeout

5.添加到系统服务

将mysql添加到服务中

# cp -af /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld_3306 # chkconfig --add mysqld_3306 # chkconfig --level 345 mysqld_3306 on

6.初始化数据库

按照配置文件对数据库进行初始化

# cd /usr/local/mysql # ./scripts/mysql_install_db --user=mysql --defaults-file=/etc/my.cnf

7.启动mysql服务

启动mysql

# service mysqld_3306 start

修改登录root用户密码

# /usr/local/mysql/bin/mysql -p -uroot -S /tmp/mysql.sock #这里直接回车就能进入数据库系统 Mysql> delete from mysql.user where user=''; Mysql> update mysql.user set password=PASSWORD(‘123456’) where user='root'; Mysql> flush privileges;
