Mysql5.6.36脚本编译安装及初始化教程
概述
本文为centos7.3自动化编译安装mysql5.3.6的脚本及后续初始化操作,话不多少,直接上脚本。
安装脚本install.py如下:
#coding=utf-8 #!/usr/bin/python import os,commands #定义变量 install_dir = '/data/mysql' data_dir = '/data/mysql/data' package_dir = '/data/mysql' log_dir = '/data/mysql/logs' current_dir = os.getcwd() cmake = 'cmake -DCMAKE_INSTALL_PREFIX=%s -DMYSQL_UNIX_ADDR=%s/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DMYSQL_DATADIR=%s -DMYSQL_TCP_PORT=3306' % (install_dir, install_dir, data_dir) #安装依赖包 os.system('yum install gcc gcc-c++ gcc-g77 autoconf automake zlib* fiex* libxml* ncurses-devel libmcrypt* libtool-ltdl-devel* make cmake perl -y') #安装函数 def install_mysql(): if os.system('groupadd mysql') == 0: print 'group mysql add success!' else: exit('group mysql add failed!') if os.system('useradd -r -g mysql -s /bin/false mysql') == 0: print 'user mysql add success!' else: exit('user mysql add failed!') if not os.path.exists(install_dir): os.system('mkdir -p %s' % install_dir) if not os.path.exists(data_dir): os.system('mkdir -p %s' % data_dir) if not os.path.exists(package_dir): os.system('mkdir -p %s' % package_dir) if not os.path.exists(log_dir): os.system('mkdir -p %s' % log_dir) if os.system('tar zxvf mysql-5.6.36.tar.gz') == 0: print 'uncompress v success!' else: exit('uncompress mysql-5.6.36.tar.gz failed!') os.chdir('mysql-5.6.36') if os.system(cmake) == 0: print '编译成功' else: exit('编译mysql失败') if os.system('make && make install') == 0: print '编译安装mysql成功' else: exit('编译安装mysql失败') if os.system('chown -R mysql:mysql %s' % install_dir) == 0: print '安装目录权限配置成功' else: exit() os.system('chown -R mysql:mysql %s' % data_dir) os.system('cd %s && touch mysql-error.log' % log_dir) os.system('chown -R mysql:mysql %s' % log_dir) os.chdir(install_dir) if os.system('./scripts/mysql_install_db --user=mysql --datadir=%s' % data_dir) == 0: print 'mysql初始化成功' else: exit('mysql初始化失败') os.system('cp support-files/mysql.server /etc/init.d/mysqld') os.system('mv /etc/my.cnf /etc/my.cnf.bak') os.chdir(current_dir) os.system('cp my.cnf /etc/my.cnf') os.system('service mysqld start') os.system('chkconfig mysqld on') install_mysql() if os.path.exists('/etc/profile'): os.system('cp /etc/profile /etc/profile.bak') if os.system('echo "PATH=%s/bin:%s/lib:$PATH" >> /etc/profile' % (install_dir, install_dir)) == 0: print '修改/etc/profile成功' else: exit() if os.system('echo "export PATH" >> /etc/profile') == 0: print '修改/etc/profile文件成功' else: exit()
配置文件my.cnf
[mysqld] basedir = /data/mysql datadir = /data/mysql/data tmpdir = /data/mysql socket = /data/mysql/mysql.sock skip-external-locking skip-name-resolve lower_case_table_names=1 auto_increment_offset = 1 auto_increment_increment = 2 #server-id ########## binlog ########## log_bin = /data/mysql/logs/mysql-bin binlog_format = row binlog_cache_size = 2M expire-logs-days = 7 ########## error log ########## log_error = /data/mysql/logs/mysql-error.log ########## slow log ########## slow_query_log = 1 slow_query_log_file = /data/mysql/logs/mysql-slow.log long_query_time = 5 ########## per_thread_buffers ########## max_connections = 1024 max_connect_errors = 1000 key_buffer_size = 64M max_allowed_packet = 128M table_open_cache = 6144 table_definition_cache = 4096 sort_buffer_size = 512K read_buffer_size = 512K join_buffer_size = 512K tmp_table_size = 64M max_heap_table_size = 64M thread_cache_size = 64 thread_concurrency = 32 bulk_insert_buffer_size = 64M ########innodb######## innodb_buffer_pool_size = 45G innodb_log_file_size = 500M innodb_log_buffer_size = 64M innodb_flush_log_at_trx_commit = 2 innodb_file_per_table = 1 innodb_file_io_threads = 4 innodb_flush_method = O_DIRECT innodb_thread_concurrency = 0 innodb_additional_mem_pool_size = 16M [mysqlhotcopy] interactive-timeout [mysqld_safe] open_files_limit = 65535
使用方法:
1.操作系统需要配置yum源
2.操作系统版本:centos7.3
3.将install.py my.cnf 和mysql安装包放一个文件夹

初始化
由于默认情况下编译安装的mysql5.6.36没有密码,命令行直接输入mysql进行登陆,执行以下sql语句
-- 初始化数据 use mysql; update user set password=PASSWORD("Abcd123") where user='root'; grant all privileges on *.* to weihu@"%" identified by "Abcd123"; delete from mysql.user where user = ''; FLUSH PRIVILEGES; -- 创建demo数据库 CREATE DATABASE `demo` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci; show databases;
