GreatSQL是mysql的国产分支版本，使用上与MySQL一致。

一、系统信息部署前提：准备一个干净的系统，确认先前没有安装过MySQL、Mariadb等相关服务，造成不必要的冲突。
1.确认OS信息

[root@mgr1 opt]# cat /etc/redhat-release CentOS Linux release 7.5.1804 (Core)[root@mgr1 opt]# uname -r 3.10.0-862.el7.x86_64

2.OS优化调整
其他一些OS调整这里不涉及，跳过。
3.临时关闭 firewall 和 selinux

systemctl stop firewalld.service setenforce 0

二、rpm安装 1.下载安装包
将这4个文件下载并上传到 /opt 目录

greatsql-client-8.0.25-16.1.el7.x86_64.rpm
greatsql-devel-8.0.25-16.1.el7.x86_64.rpm
greatsql-server-8.0.25-16.1.el7.x86_64.rpm
greatsql-shared-8.0.25-16.1.el7.x86_64.rpm

下载地址：https://gitee.com/GreatSQL/GreatSQL/releases/GreatSQL-8.0.25-16
2.安装依赖包

yum install openssl-devel net-tools perl-devel -y

3.依次安装下列软件包

rpm -ivh greatsql-shared-8.0.25-16.1.el7.x86_64.rpm rpm -ivh greatsql-client-8.0.25-16.1.el7.x86_64.rpm rpm -ivh greatsql-server-8.0.25-16.1.el7.x86_64.rpm rpm -ivh greatsql-devel-8.0.25-16.1.el7.x86_64.rpm

安装过程 greatsql-server-8.0.25-16.1.el7.x86_64.rpm 如果出现如下报错
【RPM方式安装GreatSQL 8.0.25-16】file /etc/my.cnf from install of greatsql-server-8.0.25-16.1.el7.x86_64 conflicts with file from package mariadb-libs-1:5.5.56-2.el7.x86_64
file /usr/lib64/mysql/plugin/dialog.so from install of greatsql-server-8.0.25-16.1.el7.x86_64 conflicts with file from package mariadb-libs-1:5.5.56-2.el7.x86_64
则先卸载mariadb-libs，然后再执行

yum remove mariadb-libs -y

执行 rpm -qa|grep greatsql 确认下都装上了

greatsql-shared-8.0.25-16.1.el7.x86_64 greatsql-server-8.0.25-16.1.el7.x86_64 greatsql-client-8.0.25-16.1.el7.x86_64 greatsql-devel-8.0.25-16.1.el7.x86_64

4.替换配置文件
备份下原来的/etc/my.cnf文件

mv /etc/my.cnf /etc/my.cnf.`date +"%F"`

添加配置文件，直接复制到窗口执行即可。
以下配置在2核2G内存正常运行，根据硬件情况自己微调。

echo #my.cnf [client] socket = /data/GreatSQL/mysql.sock [mysql] loose-skip-binary-as-hex prompt="(\\\\D)[\\\\u@GreatSQL][\\\\d]> " no-auto-rehash [mysqld] user= mysql port= 3306 server_id = 3306213 basedir = /usr datadir= /data/GreatSQL socket= /data/GreatSQL/mysql.sock pid-file = mysql.pid character-set-server = UTF8MB4 skip_name_resolve = 1#若你的MySQL数据库主要运行在境外，请务必根据实际情况调整本参数 default_time_zone = "+8:00"#performance setttings lock_wait_timeout = 3600 open_files_limit= 65535 back_log = 1024 max_connections = 512 max_connect_errors = 1000000 table_open_cache = 1024 table_definition_cache = 1024 thread_stack = 512K sort_buffer_size = 4M join_buffer_size = 4M read_buffer_size = 8M read_rnd_buffer_size = 4M bulk_insert_buffer_size = 64M thread_cache_size = 768 interactive_timeout = 600 wait_timeout = 600 tmp_table_size = 32M max_heap_table_size = 32M#log settings log_timestamps = SYSTEM log_error = /data/GreatSQL/error.log log_error_verbosity = 3 slow_query_log = 1 log_slow_extra = 1 slow_query_log_file = /data/GreatSQL/slow.log long_query_time = 0.1 log_queries_not_using_indexes = 1 log_throttle_queries_not_using_indexes = 60 min_examined_row_limit = 100 log_slow_admin_statements = 1 log_slow_slave_statements = 1 log_bin = /data/GreatSQL/binlog binlog_format = ROW sync_binlog = 1 binlog_cache_size = 4M max_binlog_cache_size = 2G max_binlog_size = 1G binlog_rows_query_log_events = 1 binlog_expire_logs_seconds = 604800 #MySQL 8.0.22前，想启用MGR的话，需要设置binlog_checksum=NONE才行 binlog_checksum = CRC32 gtid_mode = ON enforce_gtid_consistency = TRUE#myisam settings key_buffer_size = 32M myisam_sort_buffer_size = 128M#replication settings #master_info_repository = TABLE #relay_log_info_repository = TABLE relay_log_recovery = 1 slave_parallel_type = LOGICAL_CLOCK#可以设置为逻辑CPU数量的2倍 slave_parallel_workers = 64 binlog_transaction_dependency_tracking = WRITESET slave_preserve_commit_order = 1 slave_checkpoint_period = 2#innodb settings transaction_isolation = REPEATABLE-READ innodb_buffer_pool_size = 256M innodb_buffer_pool_instances = 8 innodb_data_file_path = ibdata1:12M:autoextend innodb_flush_log_at_trx_commit = 1 innodb_log_buffer_size = 32M #innodb_log_file_size = 48M #innodb_log_files_in_group = 3 innodb_doublewrite_files = 2 innodb_max_undo_log_size = 4G# 根据您的服务器IOPS能力适当调整 # 一般配普通SSD盘的话，可以调整到 10000 - 20000 # 配置高端PCIe SSD卡的话，则可以调整的更高，比如 50000 - 80000 innodb_io_capacity = 4000 innodb_io_capacity_max = 8000 innodb_open_files = 65534 innodb_flush_method = O_DIRECT innodb_lru_scan_depth = 4000 innodb_lock_wait_timeout = 10 innodb_rollback_on_timeout = 1 innodb_print_all_deadlocks = 1 innodb_online_alter_log_max_size = 4G innodb_print_ddl_logs = 1 innodb_status_file = 1#注意: 开启 innodb_status_output & innodb_status_output_locks 后, 可能会导致log_error文件增长较快 innodb_status_output = 0 innodb_status_output_locks = 1 innodb_sort_buffer_size = 67108864#innodb monitor settings innodb_monitor_enable = "module_innodb" innodb_monitor_enable = "module_server" innodb_monitor_enable = "module_dml" innodb_monitor_enable = "module_ddl" innodb_monitor_enable = "module_trx" innodb_monitor_enable = "module_os" innodb_monitor_enable = "module_purge" innodb_monitor_enable = "module_log" innodb_monitor_enable = "module_lock" innodb_monitor_enable = "module_buffer" innodb_monitor_enable = "module_index" innodb_monitor_enable = "module_ibuf_system" innodb_monitor_enable = "module_buffer_page" innodb_monitor_enable = "module_adaptive_hash"#pfs settings performance_schema = 1 #performance_schema_instrument = %memory%=on performance_schema_instrument = %lock%=on > /etc/my.cnf

5.创建数据目录

mkdir -p /data/GreatSQL chown mysql.mysql /data/GreatSQL

6.启动服务
rpm安装会自动生成一个mysqld.service的启动服务，并设置为开机自启动，所以我们直接开启服务即可。
如果是第一次开启，mysqld.service服务会调用/usr/bin/mysqld_pre_systemd脚本进行数据初始化操作，此过程时间较长，请耐心等待！

systemctl start mysqld.service

如果开启过程出现
Job for mysqld.service failed because the control process exited with error code. See " systemctl status mysqld.service" and " journalctl -xe" for details.
执行 journalctl -xe 发现以下内容，确认下相关的/data/GreatSQL/error.log文件存在且配置权限正常，可以尝试关闭selinux再进行开启

...... [ERROR] [MY-010338] [Server] Cant find error-message file /usr/local/GreatSQL-8.0.25-15-Linux-glibc2.17-x86_64/s [Warning] [MY-010091] [Server] Cant create test file /data/GreatSQL/mysqld_tmp_file_case_insensitive_test.lower-t [Warning] [MY-010159] [Server] Setting lower_case_table_names=2 because file system for /data/GreatSQL/ is case in [ERROR] [MY-010187] [Server] Could not open file /data/GreatSQL/error.log for error logging: Permission denied ......

7.查看开启状态
启动服务后，查看下服务启动状态，关键字active (running)

[root@localhost GreatSQL]# systemctl status mysqld.service ● mysqld.service - MySQL Server Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled) Active: active (running) since Tue 2022-05-17 05:13:09 EDT; 50s ago Docs: man:mysqld(8) http://dev.mysql.com/doc/refman/en/using-systemd.html Process: 32417 ExecStartPre=/usr/bin/mysqld_pre_systemd (code=exited, status=0/SUCCESS) Main PID: 32506 (mysqld) Status: "Server is operational" CGroup: /system.slice/mysqld.service └─32506 /usr/sbin/mysqld

8.启动后查看初始化的密码
记录下输出的初始化密码，稍后改密需要用到

cat /data/GreatSQL/error.log |grep root@localhost|awk print $NF

9.设置下root密码

# 1.使用初始化的密码登陆 mysql -p -uroot -S /data/GreatSQL/mysql.sock# 2.设置修改密码，把 GreatSQL.2022! 改成你需要设置的密码 [root@GreatSQL][(none)]> set password for root@localhost=GreatSQL.2022!; [root@GreatSQL][(none)]> flush privileges; [root@GreatSQL][(none)]> quit# 3.新密码登陆下 mysql -uroot -p -S /data/GreatSQL/mysql.sock

10.查看下版本
