sysbench壓測環境：

sysbench server：172.16.7.105

壓測資料庫伺服器：MHA架構，172.16.7.100（主節點）、172.16.7.101、172.16.7.102

MySQL在172.16.7.105（安裝MySQL5.7.26）部署目錄：/opt/mysql/

主要壓測172.16.7.100主節點

172.16.7.100配置：

MySQL5.7.26

CPU：4核

記憶體：8G

innodb_buffer_pool_size = 28G

innodb_log_file_size = 512M

innodb_log_files_in_group = 2

innodb_log_buffer_size=16M

MySQL8.0.17

CPU：4核

記憶體：8G

innodb_buffer_pool_size = 28G

innodb_log_file_size = 512M

innodb_log_files_in_group = 2

innodb_log_buffer_size=16M

前置工作

1.完成MySQL的安裝

2.完成動態庫檔案的安裝

yum install -y openssl libtool

#可能遇到的報錯

1.在make之前，需要修改lib庫，否則會得到一個報錯:/usr/bin/ld: cannot find -lmysqlclient_r

因為安裝中指向的lib是/opt/mysql/lib

cd /opt/mysql/lib

ln -s libmysqlclient.so.20.3.9 libmysqlclient_r.so

2.make的時候沒有明顯錯誤，執行./sysbench時報錯

./sysbench: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory

ln -s /opt/mysql/lib/libmysqlclient.so.18 /usr/lib64

如果報錯為

/usr/local/sysbench/bin/sysbench: error while loading shared libraries: libmysqlclient.so.20: cannot open shared object file: No such file or directory

那麼就執行

ln -s /opt/mysql/lib/libmysqlclient.so.20 /usr/lib64

下載sysbench：

wget

部署：

tar -xf sysbench-0.4.12-1.1.tgz

mv sysbench-0.4.12-1.1 sysbench

cp -r sysbench /usr/local/sysbench

cd /usr/local/sysbench

./autogen.sh

#生成configure檔案

./configure --prefix=/usr/local/sysbench/ --with-mysql=/opt/mysql/ --with-mysql-includes=/opt/mysql/include/ --with-mysql-libs=/opt/mysql/lib/

注意此處的includes必須是mysql對應的include目錄，libs也是mysql對應的lib目錄

完成安裝

make&&make install

（確認沒有報錯）

驗證安裝

/usr/local/sysbench/bin/sysbench --help

如果出現下列文字，說明部署成功

[root@GTID01 bin]# /usr/local/sysbench/bin/sysbench --help

Missing required command argument.Usage: sysbench [general-options]... --test= [test-options]... command

General options:

--num-threads=N number of threads to use [1]

--max-requests=N limit for total number of requests [10000]

...

增加環境變數

echo -e "export PATH=\$PATH:/usr/local/sysbench/bin" >> /etc/profile

source /etc/profile

使用sysbench進行測試

先到被測試的庫裡建庫，建使用者，授權（這裡透過105去測試100庫）

mysql -h 172.16.7.100 -uroot -p

...

create database sbtest; ##因為lua指令碼里面這裡設定的就是sbtest庫，庫名需要與指令碼里的內容保持一致

create user tpcc@'%' identified by 'tpcc';

grant all privileges on sbtest.* to tpcc@'%';

flush privileges;

MySQL8.0需要加：

alter user tpcc@'%' identified with 'mysql_native_password' by 'tpcc';

會產生報錯的操作（將oltp.lua中的mysiam修改成innodb後，會找不到表）

cd /usr/local/sysbench/sysbench/tests/db/

cp oltp.lua oltp_innodb.lua

sed -i 's/myisam/innodb/g' /usr/local/sysbench/sysbench/tests/db/oltp_innodb.lua

測試多表的壓測

執行prepare

sysbench --mysql-host=172.16.7.100 --mysql-port=3306 --mysql-user=tpcc --mysql-password=tpcc --test=/usr/local/sysbench/sysbench/tests/db/oltp.lua --oltp_tables_count=10 --oltp-table-size=100000 --rand-init=on prepare

執行run

sysbench --mysql-host=172.16.7.100 --mysql-port=3306 --mysql-user=tpcc --mysql-password=tpcc --test=/usr/local/sysbench/sysbench/tests/db/oltp.lua --oltp_tables_count=10 --oltp-table-size=100000 --num-threads=4 --oltp-read---report-interval=5 --rand-type=uniform --max-time=30 --max-requests=0 --percentile=99 run

--num-threads=4　　　　//執行緒數為4

--max-time=30　　　　　　//測試時間為30s

--report-interval=5　　　　//報告列印週期為5s

--oltp-read->

--max-requests=0 //最大執行次數這裡不做限制，只由max-time進行限制

MySQL8.0我是用的30001埠

MySQL5.7用32執行緒壓測結果：

需要重點關注的幾個測試結果

★總的事物數，每秒事務數TPS，QPS，時間統計資訊（最大、最小、平均、99%以上語句響應時間）★

透過sysbench結果來判定資料庫的能力主要還是透過TPS
