这篇文章主要介绍了MySQL 5.7.21如何在Linux平台中安装Part 2，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。 1. 目录规划 目录名称 参数名称 路径地址 安装目录 basedir /usr/local/mysql 数据文件目录 datadir /data/mysql/data 临时文件目录 tmpdir /data/mysql/tmp socket文件目录 socket /data/mysql/data/mysql.sock bin日志文件目录 log_bin /datalog/mysql/binlog relay日志文件目录 relay_log /datalog/mysql/relaylog 2. MySQL 5.7 下载 目前MySQL 社区的GA 提供5 和8 的下载 由于目前大多数系统用的还是5的版本 这里统一使用5的版本 注意，下面是按照5.7.21的版本安装，5.25相同 MySQL Community Server 5.7.25 MySQL 5.7.21如何在Linux平台中安装Part 2 3. 新建用户及目录 /usr/sbin/groupadd -g 105 mysql /usr/sbin/useradd -u 105 -g mysql mysql echo "mysql123" |passwd mysql --stdin 4. 新建目录 mkdir -p /data/mysql/software mkdir -p /usr/local/mysql mkdir -p /data/mysql/data mkdir -p /datalog/mysql/binlog mkdir -p /datalog/mysql/relaylog chown -R mysql:mysql /usr/local/mysql mkdir -p /data/mysql/tmp chown -R mysql:mysql /data/mysql chown -R mysql:mysql /datalog/mysql/ 5. 配置环境变量 su - mysql vim ~/.bash_profile export MYSQL_HOME=/usr/local/mysql export PATH=$HOME/bin:$MYSQL_HOME/bin:$PATH export LD_LIBRARY_PATH=$MYSQL_HOME/lib:$LD_LIBRARY_PATH source ~/.bash_profile 6. 建立配置文件 我们这里建立 /etc/my.cnf [mysql] user = password = [mysqld] #-----------------MySQL Basic Setting-----------------# server-id = 1723161113 port = 3306 user = mysql pid-file = mysql.pid character_set_server = utf8mb4 default_storage_engine = InnoDB skip_name_resolve = 1 lower_case_table_names = 1 explicit_defaults_for_timestamp = 1 open_files_limit = 65535 max_connections = 1000 max_connect_errors = 100000 basedir = /usr/local/mysql datadir = /data/mysql/data tmpdir = /data/mysql/tmp socket = /data/mysql/data/mysql.sock query_cache_type = query_cache_size = join_buffer_size = 64M tmp_table_size = 64M max_allowed_packet = 32M read_buffer_size = 16M read_rnd_buffer_size = 32M sort_buffer_size = 32M #-----------------MySQL Log Setting-----------------# log_error = mysql-error.log log_bin = /datalog/mysql/binlog/mysql-bin.log slow_query_log_file = mysql-slow.log relay_log = /datalog/mysql/relaylog/mysql-relay.log log_slave_updates = 1 sync_binlog = 1 relay_log_recovery = 1 binlog_format = row expire_logs_days = 14 slow_query_log = 1 long_query_time = 2 log_queries_not_using_indexes = 1 log_throttle_queries_not_using_indexes = 10 log_slow_admin_statements = 1 log_slow_slave_statements = 1 min_examined_row_limit = 1000 #-----------------MySQL Replication Setting-----------------# slave_skip_errors = ddl_exist_errors master_info_repository = TABLE relay_log_info_repository = TABLE gtid_mode = on enforce_gtid_consistency = 1 binlog_rows_query_log_events = 1 #-----------------MySQL InnoDB Setting-----------------# innodb_page_size = 16384 innodb_buffer_pool_size = 25600M innodb_data_file_path = ibdata1:1G:autoextend innodb_buffer_pool_instances = 8 innodb_file_per_table = 1 innodb_buffer_pool_load_at_startup = 1 innodb_buffer_pool_dump_at_shutdown = 1 innodb_flush_log_at_trx_commit = 1 innodb_lock_wait_timeout = 5 innodb_io_capacity = 800 innodb_io_capacity_max = 2000 innodb_flush_method = O_DIRECT innodb_file_format = Barracuda innodb_file_format_max = Barracuda innodb_undo_logs = 128 innodb_undo_tablespaces = 3 innodb_flush_neighbors = 1 innodb_log_file_size = 2G innodb_log_buffer_size = 16777216 innodb_print_all_deadlocks = 1 innodb_strict_mode = 1 innodb_sort_buffer_size = 67108864 #-----------------MySQL semi Replication Setting-----------------# #plugin_dir = /usr/local/mysql/lib/plugin #plugin_load = "rpl_semi_sync_master=semisync_master.so;rpl_semi_sync_slave=semisync_slave.so" #loose_rpl_semi_sync_master_enabled = 1 #loose_rpl_semi_sync_slave_enabled = 1 #loose_rpl_semi_sync_master_timeout = 5000 修改my.cnf权限 chown mysql:mysql /etc/my.cnf 7. 依赖包检查 libaio-0.3.107-10.el6.x86_64 libaio-devel-0.3.107-10.el6.x86_64 lvm2-2.02.143-7.el6_8.1.x86_64 8. 卸载以前版本 如果有以前版本的MySQL ，则需要先下载 如只有lib库则可以不用动 RedHat Enterprise Linux 6适用】 # rpm -qa|grep -i mysql mysql-libs-5.1.71-1.el6.x86_64 qt-mysql-4.6.2-26.el6_4.x86_64 mysql-5.1.71-1.el6.x86_64 mysql-server-5.1.71-1.el6.x86_64 #yum remove mysql-5.1.71-1.el6.x86_64 qt-mysql-4.6.2-26.el6_4.x86_64 mysql-libs-5.1.71-1.el6.x86_64 mysql-server-5.1.71-1.el6.x86_64 【RedHat Enterprise Linux 7适用】 # rpm -qa|grep -i mariadb* mariadb-server-5.5.52-1.el7.x86_64 mariadb-libs-5.5.52-1.el7.x86_64 mariadb-embedded-5.5.52-1.el7.x86_64 mariadb-test-5.5.52-1.el7.x86_64 mariadb-bench-5.5.52-1.el7.x86_64 mariadb-5.5.52-1.el7.x86_64 mariadb-devel-5.5.52-1.el7.x86_64 mariadb-embedded-devel-5.5.52-1.el7.x86_64 # yum remove -y mariadb* 9. 解压文件 9.1 解压安装文件 su - mysql tar xzvf mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz -C /usr/local/mysql/ --strip-components=1 9.2 配置服务文件 这里将mysql.server文件拷贝值init.d目录使其可以当作服务启停 cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld 这里修改下面几处 vim /etc/init.d/mysqld basedir=/usr/local/mysql datadir=/data/mysql/data lockdir='/data/mysql/data' mysqld_pid_file_path=/data/mysql/data/mysql.pid 10. 初始化数据库 接下来我们初始化MySQL # su - mysql $cd /usr/local/mysql $/usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --initialize --user=mysql 初始化过程中可以通过error文件查看进度 tail -f /data/mysql/data/mysql-error.log 11. 启动数据库 $ /usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf --user=mysql & $ netstat -lntp|grep mysqld 后续可以使用如下命令启停数据库 service mysqld stop service mysqld start service mysqld restart 设置MySQL自启动 chkconfig mysqld on 12. 连接数据库 默认密码在error文件中有 cat /data/mysql/data/mysql-error.log |grep password 使用如下命令连接 mysql -S /data/mysql/data/mysql.sock -uroot -ppassword  （编辑：威海站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
