001linux mysql源码安装

1、配置dns

 1)编辑文件/etc/resolv.conf

  vi /etc/resolv.conf

 2）添加如下配置

  nameserver 112.4.0.55

  

2、下载mysql安装包：mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz

 https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz

3、上传安装包到/data/soft目录

 /data/soft/mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz

4、卸载已安装mysql

 #查询已安装mysql

 rpm -qa|grep mysql

 #依次卸载上一步查询结果，...代表上一步查询结果项

 rpm -e ...

 #查看是否存在mysql进程，如果存在依次kill -9停止进程

 ps -ef|grep mysql

5、创建mysql用户、家目录、登录密码;创建mysql安装目录，并属主、属主修改为mysql、添加到data用户组

 useradd -d /home/mysql -pData mysql

 mkdir /data/file/mysql/

 chown mysql:mysql /data/file/mysql/

 #添加到data组

 usermod -a -G data mysql

6、把安装包属主、属主修改为mysql

 chown mysql:mysql /data/soft/mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz

7、切换至mysql用户

 su - mysql

8、解压安装包到/data/file/mysql/目录

 tar -xzvf /data/soft/mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz -C /data/file/mysql/

 mv /data/file/mysql/mysql-5.7.22-linux-glibc2.12-x86_64/* /data/file/mysql/

9、初始化数据库

 /data/file/mysql/bin/mysqld --user=mysql --basedir=/data/file/mysql --datadir=/data/file/mysql/data --initialize

    控制台会打印root密码，记录下：QhfhIH4t+8oG

10、修改启动文件配置：

 #编辑文件

 vi /data/file/mysql/support-files/mysql.server

 #找到basedir，datadir，并配置如下：

  basedir=/data/file/mysql

  datadir=/data/file/mysql/data

  

11、切换至root用户，修改/etc/my.cnf配置文件

 su - root

 vi /etc/my.cnf

 #清空后添加如下配置

  [client] 

  port=3306

  socket=/data/file/mysql/mysql.sock

  default-character-set=utf8

  [mysqld]

  port=3306

  character-set-server=utf8

  default_storage_engine = innodb

  log_timestamps = SYSTEM

  socket = /data/file/mysql/mysql.sock

  basedir= /data/file/mysql

  datadir = /data/file/mysql/data # 数据路径

  pid-file = /data/file/mysql/mysql.pid

  max_connections = 1000

  max_connect_errors = 1000

  table_open_cache = 1024

  max_allowed_packet = 128M

  open_files_limit = 65535

  explicit_defaults_for_timestamp=true

  #####====================================[innodb]==============================

  innodb_buffer_pool_size = 1024M

  innodb_file_per_table = 1

  innodb_write_io_threads = 4

  innodb_read_io_threads = 4

  innodb_purge_threads = 2

  innodb_flush_log_at_trx_commit = 1

  innodb_log_file_size = 512M

  innodb_log_files_in_group = 2

  innodb_log_buffer_size = 16M

  innodb_max_dirty_pages_pct = 80

  innodb_lock_wait_timeout = 30

  innodb_data_file_path=ibdata1:1024M:autoextend

  #####====================================[log]==============================

  log_error = /data/file/mysql/mysql-error.log 

  slow_query_log = 1

  long_query_time = 1 

  slow_query_log_file = /data/file/mysql/mysql-slow.log

12、添加mysql命令链接

 ln -s /data/file/mysql/bin/mysql /usr/local/bin/mysql

13、配置mysql启动服务

 cp /data/file/mysql/support-files/mysql.server /etc/init.d/mysqld;

 chmod 755 /etc/init.d/mysqld;

 chkconfig --add mysqld;

 chkconfig mysqld on;

14、启动mysql服务器、设置root密码及远程访问权限

  ps -ef|grep mysql 停掉已有的mysql进程

  service mysqld start;

  mysql -u root -p

  set password=password('Data');

  update mysql.user set host='%' where user='root';

  flush privileges;

15、创建应用数据库、应用帐号及赋权

 create database rddb DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

 grant all privileges on rddb.* to rddb@'%' identified by 'cmsoft#098';

 grant all privileges on mysql.* to rddb @'%' identified by 'cmsoft#098';

16、打开3306端口，允许远程访问

 firewall-cmd --zone=public --add-port=3306/tcp --permanent

 firewall-cmd --reload

Note：

 1、启动错误

  Starting MySQL.. ERROR! The server quit without updating PID file (/data/file/mysql/mysql.pid).

    解决：

  cd /data/file/mysql/data

  rm ibdata1 ib_logfile0 ib_logfile1

  service mysqld start

 2、帐号密码、数据库 

  管理员帐号：root Data

  应用帐号：rddb cmsoft#098

  数据库；10.142.114.99:3306/rddb
