amoeba mysql_从零开始：Mysql基于Amoeba的集群搭建

發(fā)布時(shí)間：2023/12/18 数据库 28 豆豆

生活随笔收集整理的這篇文章主要介紹了 amoeba mysql_从零开始：Mysql基于Amoeba的集群搭建小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

從零開始：Mysql基于Amoeba的集群搭建

準(zhǔn)備環(huán)境

1、mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz

2、amoeba-mysql-binary-2.0.1-BETA.tar.gz

3、Centos7

下載安裝配置運(yùn)行

1、mysql安裝

使用wget命令下載安裝

//創(chuàng)建目錄

mkdir /software/mysql

cd /software/mysql

wget https://dev.mysql.com/get/downloads/mysql-5.7/mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz

下載安裝完成后使用tar命令解壓

tar zxvf mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz /software/mysql/mysql3307

我這里搭建的是一主兩從模式，所以需要三個(gè)mysql實(shí)例。

cp -rf /software/mysql/mysql3307 /software/mysql/mysql3308

cp -rf /software/mysql/mysql3307 /software/mysql/mysql3309

2、mysql配置

在每個(gè)實(shí)例下的根路徑創(chuàng)建一個(gè)my.cnf文件，一個(gè)data目錄。

對(duì)每個(gè)實(shí)例修改相應(yīng)的端口和目錄。

#創(chuàng)建用戶組

groupadd -r mysql

useradd -r -g mysql mysql

#設(shè)置用戶組

chown -R mysql:mysql /software/mysql/

chown -R mysql /software/mysql/

使用mysqld命令初始化mysql。

cd /software/mysql/mysql3307/bin

./mysqld --user=mysql --basedir=/software/mysql/mysql3307 --datadir=/software/mysql/mysql3307/data --initialize

./mysqld --user=mysql --defaults-file=/software/mysql/mysql3307/my.cnf

cd /software/mysql/mysql3308/bin

./mysqld --user=mysql --basedir=/software/mysql/mysql3308 --datadir=/software/mysql/mysql3308/data --initialize

./mysqld --user=mysql --defaults-file=/software/mysql/mysql3308/my.cnf

cd /software/mysql/mysql3309/bin

./mysqld --user=mysql --basedir=/software/mysql/mysql3309 --datadir=/software/mysql/mysql3309/data --initialize

./mysqld --user=mysql --defaults-file=/software/mysql/mysql3309/my.cnf

初始化完成時(shí)會(huì)輸出一個(gè)mysql的初始密碼(Tsiq_elgs7iQ)。

2019-11-24T01:06:22.321101Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

把/usr/local/mysql修改成相應(yīng)的mysql目錄。

#mysq.server的部分代碼

then

basedir=/software/mysql/mysql-5.7.24-linux-glibc2.12-x86_64

sbindir=/software/mysql/mysql-5.7.24-linux-glibc2.12-x86_64/bin

libexecdir=/software/mysql/mysql-5.7.24-linux-glibc2.12-x86_64/bin

else

bindir="$basedir/bin"

if test -z "$datadir"

then

datadir="$basedir/data"

sbindir="$basedir/sbin"

libexecdir="$basedir/libexec"

3、mysql配置主從

在master服務(wù)器上(3307端口)輸入

show master status;

+------------------+----------+--------------+------------------+-------------------+

+------------------+----------+--------------+------------------+-------------------+

| mysql-bin.000006 | 154 | | | |

+------------------+----------+--------------+------------------+-------------------+

1 row in set (0.13 sec)

在slave服務(wù)器上(3308和3309端口)輸入

stop slave;

change master to master_host='localhost', master_user='root', master_password='root',master_log_file='mysql-bin.000006',master_log_pos=154,master_port=3307;

start slave;

測(cè)試：

在從服務(wù)器上輸入show slave status;

mysql> show slave status;

+----------------------------------+-------------+-------------+-------------+---------------+------------------+---------------------+------------------------------------------+---------------+-----------------------+------------------+-------------------+-----------------+---------------------+--------------------+------------------------+-------------------------+-----------------------------+------------+---------------------------------------------------------------------------------------------------------------------------+--------------+---------------------+-----------------+-----------------+----------------+---------------+--------------------+--------------------+--------------------+-----------------+-------------------+----------------+-----------------------+-------------------------------+---------------+---------------+----------------+---------------------------------------------------------------------------------------------------------------------------+-----------------------------+------------------+--------------------------------------+--------------------------------------------+-----------+---------------------+-------------------------+--------------------+-------------+-------------------------+--------------------------+----------------+--------------------+--------------------+-------------------+---------------+----------------------+--------------+--------------------+

1 row in set (0.88 sec)

其中

Slave_IO_StateWaiting for master to send event

Slave_IO_RunningYes

Slave_SQL_RunningYes

表示主從運(yùn)行成功。

4、mysql運(yùn)行

使用mysql.server運(yùn)行mysql實(shí)例

[root@iz2zeaf5jdjve80rjlsjgnz bin]# cd /software/mysql/mysql3307/support-files

[root@iz2zeaf5jdjve80rjlsjgnz support-files]# ./mysql.server start

Starting MySQL.Logging to '/software/mysql/mysql3307/data/iz2zeaf5jdjve80rjlsjgnz.err'.

... [ OK ]

進(jìn)入mysql控制臺(tái)

[root@iz2zeaf5jdjve80rjlsjgnz support-files]# cd /software/mysql/mysql-5.7.24-linux-glibc2.12-x86_64/bin

[root@iz2zeaf5jdjve80rjlsjgnz bin]# ./mysql -u root -p

Enter password:

Rows matched: 1 Changed: 1 Warnings: 0

#刷新數(shù)據(jù)庫(kù)

mysql> FLUSH PRIVILEGES;

Query OK, 0 rows affected (0.00 sec)

mysql> exit;

Bye

[root@iz2zeaf5jdjve80rjlsjgnz bin]#

使用navicat測(cè)試連接

5、amoeba安裝

使用wget下載amoeba

//創(chuàng)建目錄

mkdir /software/amoeba

cd /software/amoeba

wget https://jaist.dl.sourceforge.net/project/amoeba/Amoeba%20for%20mysql/2.x/amoeba-mysql-binary-2.0.1-BETA.tar.gz

使用tar命令解壓

tar xf amoeba-mysql-binary-2.0.1-BETA.tar.gz -C /software/amoeba

6、amoeba配置

amoeba配置主要是amoeba.xml和dbServers.xml兩個(gè)文件。

amoeba.xml

8066

${clientConnectioneManager}

128

amoeba

${amoeba.home}/conf/access_list.conf

localhost

true

${clientConnectioneManager}

500

com.meidusa.amoeba.net.ConnectionManager

com.meidusa.amoeba.net.AuthingableConnectionManager

${amoeba.home}/conf/dbServers.xml

${amoeba.home}/conf/rule.xml

${amoeba.home}/conf/ruleFunctionMap.xml

${amoeba.home}/conf/functionMap.xml

1500

master

multiPool

true

dbServers.xml

${defaultManager}

128

3307

amoeba

root

500

600000

true

localhost

3307

localhost

3308

localhost

3309

slave1,slave2

進(jìn)入三個(gè)mysql實(shí)例。

輸入命令，其中的root應(yīng)該設(shè)置為dbServers.xml中設(shè)置的用戶名和密碼。

grant all on *.* to'root'@'%' identified by 'root';

flush privileges;

7、amoeba運(yùn)行

在控制臺(tái)輸入

[root@iz2zeaf5jdjve80rjlsjgnz support-files]# /software/amoeba/bin/amoeba

amoeba start|stop

出現(xiàn)amoeba start|stop說明安裝成功。

輸入/software/amoeba/bin/amoeba start運(yùn)行

[root@iz2zeaf5jdjve80rjlsjgnz support-files]# /software/amoeba/bin/amoeba start

log4j:WARN log4j config load completed from file:/software/amoeba/conf/log4j.xml

log4j:WARN ip access config load completed from file:/software/amoeba/conf/access_list.conf

使用navicat連接8066端口

測(cè)試主從

測(cè)試主從復(fù)制

創(chuàng)建數(shù)據(jù)庫(kù)

mysql> create database rlxy93;

創(chuàng)建表，插入數(shù)據(jù)

mysql> use rlxy93;

Database changed

mysql> CREATE TABLE `admin` (

`user` char(100) DEFAULT NULL,

`password` char(100) DEFAULT NULL

) ENGINE=MyISAM DEFAULT CHARSET=utf8;

Query OK, 0 rows affected (0.32 sec)

mysql> insert into admin values('a','a');

Query OK, 1 row affected (0.28 sec)

測(cè)試讀寫分離

關(guān)閉master服務(wù)器

kill -9 20585 21308

在8066端口測(cè)試

mysql> insert into admin values('e','e');

2013 - Lost connection to MySQL server during query

mysql> select * from admin;

+------+----------+

| user | password |

+------+----------+

| a | a |

| b | b |

| c | c |

| d | d |

| e | e |

+------+----------+

5 rows in set (0.59 sec)

此時(shí)，寫入失敗，讀取正常。

寫入

關(guān)閉兩個(gè)slave服務(wù)器

kill -9 2772 9260 10010 12338

在8066端口測(cè)試

mysql> insert into admin values('r','r');

Query OK, 1 row affected (0.81 sec)

mysql> select * from admin;

2013 - Lost connection to MySQL server during query

此時(shí)，讀取失敗，寫入正常。

踩坑

建立三個(gè)mysql服務(wù)器，一定要配置

log-bin=mysql-bin //日志文件

server-id = 2 //服務(wù)器id，不要和其他的相同

replicate-do-db=test //同步的數(shù)據(jù)庫(kù)，可以不指定，默認(rèn)是所有數(shù)據(jù)庫(kù)

log-slave-updates

sync_binlog=1

slave-net-timeout=60

在使用show slave status;命令時(shí)，要有提示下面的，才會(huì)開啟主從同步。

Slave_IO_StateWaiting for master to send event

Slave_IO_RunningYes

Slave_SQL_RunningYes

同時(shí)，要關(guān)注Replicate_Do_DB的配置，比如配置的是test，那么就要在master創(chuàng)建一個(gè)test數(shù)據(jù)庫(kù)，之后的同步操作才會(huì)在test里面進(jìn)行，不會(huì)在其他數(shù)據(jù)庫(kù)里面執(zhí)行。

常見問題

提示

Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

刪除目錄下的.lock文件，刪除tmp目錄下的.sock和.lock文件。重啟mysql。

使用mysq.server時(shí)報(bào)錯(cuò)

找到[ERROR]行，這里的錯(cuò)誤是沒有權(quán)限

amoeba找不到JAVA_HOME

在amoeba文件中第一行添加

JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64/jre

后面跟著的是jdk的路徑。

amoeba運(yùn)行時(shí)提示The stack size specified is too small, Specify at least 160k.

在amoeba文件中修改

DEFAULT_OPTS="-server -Xms256m -Xmx256m -Xss256k"

總結(jié)
