1、离线安装包下载
https://dev.mysql.com/downloads/mysql/5.5.html?os=31&version=5.1
2、解压并安装
# 解压 tar xf mysql-8.0.33-1.el9.x86_64.rpm-bundle.tar # 安装MySQL dnf -y localinstall mysql-community-common-8.0.33-1.el9.x86_64.rpm dnf -y localinstall mysql-community-client-plugins-8.0.33-1.el9.x86_64.rpm dnf -y localinstall mysql-community-libs-8.0.33-1.el9.x86_64.rpm dnf -y localinstall mysql-community-client-8.0.33-1.el9.x86_64.rpm dnf -y localinstall mysql-community-icu-data-files-8.0.33-1.el9.x86_64.rpm dnf -y localinstall mysql-community-server-8.0.33-1.el9.x86_64.rpm
3、修改配置
# vim /etc/my.cnf [client] port = 3306 socket = /var/lib/mysql/mysql.sock default-character-set = utf8mb4 [mysql] prompt="MySQL [\d]> " no-auto-rehash [mysqld] port = 3306 socket = /var/lib/mysql/mysql.sock default_authentication_plugin = mysql_native_password datadir = /var/lib/mysql pid-file = /var/lib/mysql/mysql.pid user = mysql bind-address = 0.0.0.0 server-id = 1 init-connect = 'SET NAMES utf8mb4' character-set-server = utf8mb4 collation-server = utf8mb4_0900_ai_ci skip-name-resolve #skip-networking back_log = 300 max_connections = 5295 max_connect_errors = 6000 open_files_limit = 65535 table_open_cache = 1024 max_allowed_packet = 500M binlog_cache_size = 1M max_heap_table_size = 8M tmp_table_size = 128M read_buffer_size = 2M read_rnd_buffer_size = 8M sort_buffer_size = 8M join_buffer_size = 8M key_buffer_size = 256M thread_cache_size = 64 ft_min_word_len = 4 log_bin = mysql-bin binlog_format = row binlog_expire_logs_seconds = 604800 log_error = /var/lib/mysql/mysql-error.log slow_query_log = 1 long_query_time = 1 slow_query_log_file = /var/lib/mysql/mysql-slow.log performance_schema = 0 explicit_defaults_for_timestamp lower_case_table_names = 1 skip-external-locking default_storage_engine = InnoDB #default-storage-engine = MyISAM innodb_file_per_table = 1 innodb_open_files = 500 innodb_buffer_pool_size = 1024M innodb_write_io_threads = 4 innodb_read_io_threads = 4 innodb_thread_concurrency = 0 innodb_purge_threads = 1 innodb_flush_log_at_trx_commit = 2 innodb_log_buffer_size = 2M innodb_log_file_size = 32M innodb_log_files_in_group = 3 innodb_max_dirty_pages_pct = 90 innodb_lock_wait_timeout = 120 bulk_insert_buffer_size = 8M myisam_sort_buffer_size = 64M myisam_max_sort_file_size = 10G interactive_timeout = 28800 wait_timeout = 28800 binlog_rows_query_log_events = 1 log_bin_trust_function_creators = 1 log_timestamps = SYSTEM sql_mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION #sql_mode = NO_AUTO_VALUE_ON_ZERO innodb_strict_mode = 0 plugin-load=mysql_clone.so [mysqldump] quick max_allowed_packet = 500M [myisamchk] key_buffer_size = 256M sort_buffer_size = 8M read_buffer = 4M write_buffer = 4M
4、取消初始化密码
if [ ! "$(cat /usr/bin/mysqld_pre_systemd | grep -v ^\# | grep initialize-insecure )" ]; then
sed -i "s@--initialize @--initialize-insecure @g" /usr/bin/mysqld_pre_systemd
fi
5、启动服务
systemctl enable --now mysqld
