openEuler 下 Mysql 和 sysbench 测试环境搭建
环境信息
[root@localhost local]# cat /etc/os-release
NAME="openEuler"
VERSION="22.03 (LTS-SP1)"
ID="openEuler"
VERSION_ID="22.03"
PRETTY_NAME="openEuler 22.03 (LTS-SP1)"
ANSI_COLOR="0;31"
概述
/etc/my.cnf 是配置文件，安装后运行前需要配置好。
生成测试数据较费时，可以将生成的数据备份起来，以后直接拷贝到 /data/文件夹下
安装流程
Mysql 安装
配置环境
groupadd mysql
useradd -g mysql mysql
passwd mysqlrm -rf /data/mysql
mkdir -p /data/mysql
cd /data/mysql
mkdir data tmp run log relaylogchown -R mysql:mysql /data[root@localhost mysql]# ll /

[root@localhost ~]# yum install mysql
[root@localhost ~]# which mysql
/usr/bin/mysql
或
[root@localhost sysbench-0.5-script]# which mysql
/usr/local/mysql/bin/mysql[root@localhost /]# rpm -qa | grep mysql
mysql-common-8.0.29-2.oe2203sp1.x86_64
mysql-8.0.29-2.oe2203sp1.x86_64安装mysql-server
在yum install mysql-server 后，才会找到mysqld
[root@localhost local]# yum install mysql-server
[root@localhost local]# find / -name mysqld
/run/mysqld
/usr/libexec/mysqld
/usr/sbin/mysqld
/etc/logrotate.d/mysqld
运行
如果是安装在/usr/local/mysql下
rm -f /etc/my.cnf
touch /etc/my.cnf
vim /etc/my.cnf
[mysqld_safe]
log-error=/data/mysql/log/mysql.log
pid-file=/data/mysql/run/mysqld.pid

tmpdir=/data/mysql/tmp
datadir=/data/mysql/data
default_authentication_plugin=mysql_native_password
port=3306

#skip-grant-tables安装在/usr 下
[mysqld_safe]

tmpdir=/data/mysql/tmp
datadir=/data/mysql/data
default_authentication_plugin=mysql_native_password
port=3306
user=mysql
#skip-grant-tables
修改配置文件“/etc/my.cnf”的用户组和用户权限为mysql:mysql
chown mysql:mysql /etc/my.cnf
ll /etc/my.cnf
注意： 以下3步适用于20.03，而22.03我没有找到mysql.server文件，索性不用这种方式启动。此外2203在yum install之后，就可以找到which mysql，不用配置环境变量
MySQL加入service服务
chmod 777 /usr/local/mysql/support-files/mysql.server
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
chkconfig mysql on
修改“/etc/init.d/mysql”的用户组和用户权限为mysql:mysql
chown -R mysql:mysql /etc/init.d/mysql
ll /etc/init.d/mysql
配置环境变量,并使配置生效
echo export PATH=$PATH:/usr/local/mysql/bin >> /etc/profile
source /etc/profile
env
which mysql
切换到mysql用户
su - mysql
whoami
初始化数据库
mysqld --defaults-file=/etc/my.cnf --initialize
或
/usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --initialize
初始化完成后，查看数据目录下数据文件“/data/mysql/data”的用户组和用户权限为mysql:mysql（因为前面/etc/my.cnf文件中配置的操作系统用户是user=mysql）。初始化会根据my.cnf配置一些环境，并生成一个初始密码,登录的时候会用到。假如终端上没有显示，可能是输出到了/data/mysql/log/ 下面的文件中
[mysql@localhost mysql]$ mysqld --defaults-file=/etc/my.cnf --initialize

[mysql@localhost mysql]$ which mysqld
/usr/sbin/mysqld
以下三种方式都可以，2203推荐第三个，因为service前面没有注册
/usr/sbin/mysqld --defaults-file=/etc/my.cnf &
service mysql start
mysqld --defaults-file=/etc/my.cnf &
以下三种方式登录
mysql -uroot -p -S /data/mysql/run/mysql.sock
/usr/local/mysql/bin/mysql -uroot -p -S /data/mysql/run/mysql.sock
配置数据库帐号密码
(1)登录数据库以后，修改通过root用户登录数据库的密码
alter user 'root'@'localhost' identified by "123456";
(2)创建全域root用户（允许root从其他服务器访问
create user 'root'@'%' identified by '123456';
(3)进行授权
grant all privileges on *.* to 'root'@'%';
flush privileges;
退出数据库
exit
关闭数据库：三种方式
service mysql stop
mysqladmin -uroot -p123456 shutdown -S /data/mysql/run/mysql.sock
/usr/local/mysql/bin/mysqladmin -uroot -p123456 shutdown -S /data/mysql/run/mysql.sock
ps -ef | grep mysql
sysbench 安装及测试
yum -y install automake libtool* mariadb-devel
cd /home
wget https://github.com/akopytov/sysbench/archive/0.5.zip --no-check-certificate
mv 0.5.zip sysbench-0.5.zip
unzip sysbench-0.5.zip
vi /home/sysbench-0.5/sysbench/drivers/mysql/drv_mysql.c
在mysql_drv_real_connect函数末尾找到“return mysql_real_connect(…) == NULL;”。
替换
#if 0return mysql_real_connect(con,db_mysql_con->host,db_mysql_con->user,db_mysql_con->password,db_mysql_con->db,db_mysql_con->port,db_mysql_con->socket,
#if MYSQL_VERSION_ID >= 50000CLIENT_MULTI_STATEMENTS
#else0
#endif) == NULL;
#elseunsigned int timeout = 5;if (mysql_options(con, MYSQL_OPT_CONNECT_TIMEOUT, (const char *)&timeout)) {DEBUG("0x%p mysql_options MYSQL_OPT_CONNECT_TIMEOUT failed", con);}int ret = 0;int i = 0;for (; i < 5; i++) {ret = (mysql_real_connect(con,db_mysql_con->host,db_mysql_con->user,db_mysql_con->password,db_mysql_con->db,db_mysql_con->port,db_mysql_con->socket,
#if MYSQL_VERSION_ID >= 50000CLIENT_MULTI_STATEMENTS
#else0
#endif) == NULL);if (ret == 0) {DEBUG("0x%p mysql_options succeed", con);break;}DEBUG("0x%p mysql_options MYSQL_OPT_CONNECT_TIMEOUT timeout", con);usleep(1000);}return ret;
#endif
编译安装
./autogen.sh./configuremake -j128make -j128 install
上述步骤最好在/home下操作，因为后续调用的测试脚本（比如test_oltp_mix.sh）里面的路径是写死的。
登录数据库后创建sysbench数据库：
create database sysbench;
show databases;
use sysbench;
show tables;
登录Sysbench工具客户端，向MySQL数据库服务器导入数据。
执行如下命令向服务器导入测试数据，数据量为100张表*1万行数据（100*10000）
/home/sysbench-0.5/sysbench/sysbench --db-driver=mysql --test=/home/sysbench-0.5/sysbench/tests/db/parallel_prepare.lua --oltp-test-mode=complex --mysql-host=127.0.0.1 --mysql-port=3306 --mysql-db=sysbench --mysql-user=root --mysql-password=123456 --max-time=7200 --max-requests=0 --mysql-table-engine=innodb --oltp-table-size=10000 --oltp-tables-count=100 --rand-type=special --rand-spec-pct=100 --num-threads=16 prepare
注意根据机器能力和使用场景，生成数据，自己的小虚拟机数据生成小一点。这个脚本末尾时prepare
一些数据库相关的lua测试代码：
[root@localhost sysbench-0.5]# cd sysbench/tests/db/
[root@localhost db]# ls
bulk_insert.lua delete.lua Makefile Makefile.in oltp_simple.lua select.lua select_random_ranges.lua update_non_index.lua
common.lua insert.lua Makefile.am oltp.lua parallel_prepare.lua select_random_points.lua update_index.lua
下面的命令会生成sbtest1~100
[root@localhost db]# /home/sysbench-0.5/sysbench/sysbench --db-driver=mysql --test=/home/sysbench-0.5/sysbench/tests/db/parallel_prepare.lua --oltp-test-mode=complex --mysql-host=127.0.0.1 --mysql-port=3306 --mysql-db=sysbench --mysql-user=root --mysql-password=123456 --max-time=7200 --max-requests=0 --mysql-table-engine=innodb --oltp-table-size=10000 --oltp-tables-count=100 --rand-type=special --rand-spec-pct=100 --num-threads=16 prepare

如果生成的数据量太大，/目录下放不下：
可以建立一个软连接（假设/home空间大）：
mv /data /home/mysql_data
ln -s /home/mysql_data/data /data
删除操作：
[root@localhost sysbench-0.5-script]# /home/sysbench-0.5/sysbench/sysbench --db-driver=mysql --test=/home/sysbench-0.5/sysbench/tests/db/parallel_prepare.lua --oltp-test-mode=complex --mysql-host=127.0.0.1 --mysql-port=3306 --mysql-db=sysbench --mysql-user=root --mysql-password=123456 --max-time=7200 --max-requests=0 --mysql-table-engine=innodb --oltp-table-size=10000 --oltp-tables-count=100 --rand-type=special --rand-spec-pct=100 --num-threads=16 cleanup
sysbench 0.5: multi-threaded system evaluation benchmarkDropping table 'sbtest1'...
Dropping table 'sbtest2'...
Dropping table 'sbtest3'...

里面包含了8个场景和一个mix场景的测试脚本，以mix场景测试为例（需要登录数据库）：
chmod 777 *
./test_oltp_mix.sh -h 127.0.0.1 -P 3306 -u root -p 123456 -D sysbench -C 100 -S 10000 -t 16 -c run
-D sysbench ： 选择sysbench数据库
只要数据库没重启，执行写场景（INDEX、NONINDEX、DELETE）之前，需要执行1次mix场景进行预热。
输出如下：
[root@localhost sysbench-0.5-script]# ./test_oltp_mix.sh -h 127.0.0.1 -P 3306 -u root -p 123456 -D sysbench -C 100 -S 10000 -t 16 -c run

安装mysql，在第一次启动前，要初始化数据库，完成data文件夹初始化，和密码初始化。
启动mysql后，再执行登录操作
一般生成大量数据较慢，频繁测试建议把数据存到/data/路径下，下次拷贝过来直接用
可以参考test_oltp_mix.s 自定义脚本
常用操作
查看数据库进程
ps -ef | grep mysql
查看数据库版本
[mysql@localhost mysql]$ mysql -V
mysql Ver 8.0.29 for Linux on x86_64 (Source distribution)
查看数据库监测端口
yum -y install net-toolsnetstat -anptnetstat -anpt | grep mysqlnetstat -anpt | grep 3306
启动，关闭数据库
mysql> show processlist;
可能遇到的问题
不同yum源 install的路径可能不一样，需要在my.cnf中适配
某些操作失败，尝试关闭selinux
mysqld: Can't create/write to file '/data/mysql/tmp/ibV4zkJM
[root@localhost local]# getenforce
Enforcing
[root@localhost local]# setenforce 0
[root@localhost local]# getenforce
Permissive
查看SELinux状态及关闭SELinux
初始化/启动数据库失败，DATA路径无效
