   – MYSQL PERFORMANCE TUNING PRIMER –
   • By: Matthew Montgomery -

MySQL Version 5.5.52-MariaDB x86_64

Uptime = 0 days 0 hrs 7 min 2 sec
Avg. qps = 0
Total Questions = 39
Threads Connected = 1

Warning: Server has not been running for at least 48hrs.
It may not be safe to use these recommendations //告诉服务运行还不超过48个小时，这样不安全

To find out more information on how each of these
runtime variables effects performance visit:

Visit http://www.mysql.com/products/enterprise/advisors.html
for info about MySQL’s Enterprise Monitoring and Advisory Service

SLOW QUERIES
The slow query log is NOT enabled.
Current long_query_time = 10.000000 sec.
You have 0 out of 60 that take longer than 10.000000 sec. to complete
Your long_query_time seems to be fine

BINARY UPDATE LOG
The binary update log is NOT enabled.
You will not be able to do point in time recovery
See http://dev.mysql.com/doc/refman/5.5/en/point-in-time-recovery.html
//告诉binary log没有设置生存时间，会一直保存下来，只到主服务器重起，
//并且binlog的同步并没有激活，如果服务器崩溃binlog数据将丢失

WORKER THREADS
Current thread_cache_size = 0
Current threads_cached = 0
Current threads_per_sec = 1
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 151
Current threads_connected = 1
Historic max_used_connections = 1
The number of used connections is 0% of the configured maximum.
You are using less than 10% of your configured max_connections.
Lowering max_connections could help to avoid an over-allocation of memory
See “MEMORY USAGE” section to make sure you are not over-allocating
//告诉目前已连接的最大连接和设置的最大连接的比率差不多是0％，
//建议我把最大连接设置小一点，可以节省一点内存

INNODB STATUS
Current InnoDB index space = 0 bytes
Current InnoDB data space = 0 bytes
Current InnoDB buffer pool free = 96 %
Current innodb_buffer_pool_size = 128 M
Depending on how much space your innodb indexes take up it may be safe
to increase this value to up to 2 / 3 of total system memory

MEMORY USAGE
Max Memory Ever Allocated : 274 M
Configured Max Per-thread Buffers : 419 M
Configured Max Global Buffers : 272 M
Configured Max Memory Limit : 691 M
Physical Memory : 3.68 G
Max memory limit seem to be within acceptable norms

KEY BUFFER
Current MyISAM index space = 99 K
Current key_buffer_size = 128 M
Key cache miss rate is 1 : 2
Key buffer free ratio = 81 %
Your key_buffer_size seems to be fine

QUERY CACHE
Query cache is supported but not enabled //查询缓存是支持的，但是没有激活
Perhaps you should set the query_cache_size //建议我设置一下query_cache_size的大小

SORT OPERATIONS
Current sort_buffer_size = 2 M
Current read_rnd_buffer_size = 256 K
No sort operations have been performed
Sort buffer seems to be fine

JOINS
tuning-primer.sh: line 402: export: `2097152’: not a valid identifier
Current join_buffer_size = 132.00 K
You have had 0 queries where a join could not use an index properly
Your joins seem to be using indexes properly

OPEN FILES LIMIT
Current open_files_limit = 1024 files
The open_files_limit should typically be set to at least 2x-3x
that of table_cache if you have heavy MyISAM usage.
Your open_files_limit value seems to be fine

TABLE CACHE
Current table_open_cache = 400 tables
Current table_definition_cache = 400 tables
You have a total of 41 tables
You have 41 open tables.
The table_cache value seems to be fine

TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 16 M
Of 348 temp tables, 9% were created on disk
Created disk tmp tables ratio seems fine

TABLE SCANS
Current read_buffer_size = 128 K
Current table scan ratio = 4 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 0 : 318
Your table locking seems to be fine

10. 最后根据结果做相应的优化

首先查看mariadb数据库最大连接数，默认为151

show variables like ‘max_connections’;

配置/etc/my.cnf
[mysqld]新添加一行如下参数：
max_connections=1000
重启mariadb服务，再次查看mariadb数据库最大连接数，可以看到最大连接数是214，并非我们设置的1000。

这是由于mariadb有默认打开文件数限制。可以通过配置/usr/lib/systemd/system/mariadb.service来调大打开文件数目。

配置/usr/lib/systemd/system/mariadb.service
[Service]新添加两行如下参数：
LimitNOFILE=10000
LimitNPROC=10000

重新加载系统服务，并重启mariadb服务
systemctl daemon-reload
systemctl restart mariadb.service

再次查看mariadb数据库最大连接数，可以看到最大连接数已经是1000

1. Lynis是针对Unix/Linux的安全检查工具，可以发现潜在的安全威胁。这个工具覆盖可疑文件监测、漏洞、恶意程序扫描、配置错误等。
   A. 检查项举例：
   B. 系统允许的登陆操作
   C. 失效的SSL证书
   D. 不需要密码的账户
   E. 未授权的文件
   F. 配置错误
2. 安装epel：
   a. rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
3. 安装lynis：
   a. yum –enablerepo=epel -y install lynis
4. 扫描系统：
   a. lynis audit system

5. 查看分析日志：
   a. 分析日志保存在：/var/log/lynis.log
   b. 分析报告保存在：/var/log/lynis-report.dat
   c. 需要查看的是分析报告：
   d. 搜索 “warning” “suggestion”找到建议内容
   grep -E “^warning|^suggestion” /var/log/lynis-report.dat

根据上面的建议，可以针对性的修复系统漏洞

1. 安装软件包：
   a. yum -y install cockpit
   b. systemctl start cockpit
   c. systemctl enable cockpit.socket
   d. systemctl stop firewalld

2. 服务启动了就可以直接浏览器访问：
   a. https://IP:9090/
   b. root/系统密码

3. 容器管理
   a. “Start Docker”开始安装docker服务

4. 添加其他节点
