MySQL安装
主从同时操作
安装所需要的组件包
[root@chicken ~]# yum -y install gcc gcc-c++ ntp vim net-tools ncurses-devel autoconf
上传mysql安装包mysql-5.6.36.tar.gz和cmake-2.8.6.tar.gz
解压，编译安装cmake
[root@chicken ~]# tar zxf cmake-2.8.6.tar.gz
[root@chicken ~]# cd cmake-2.8.6/
[root@chicken cmake-2.8.6]# ./configure && gmake && gmake install解压mysql并编译安装mysql
[root@chicken ~]# tar zxf mysql-5.6.36.tar.gz
[root@chicken ~]# cd mysql-5.6.36/
[root@chicken mysql-5.6.36]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DSYSCONFDIR=/etc -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all
[root@chicken mysql-5.6.36]# make && make install
创建mysql用户和组
[root@chicken ~]# groupadd mysql
[root@chicken ~]# useradd -M -s /sbin/nologin mysql -g mysql
修改mysql安装目录权限，复制默认配置文件
[root@chicken ~]# chown -R mysql:mysql /usr/local/mysql
[root@chicken ~]# cp support-files/my-default.cnf /etc/my.cnfMySQL数据库初始化
[root@chicken ~]# ./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data添加mysql到系统服务
[root@chicken ~]# cp support-files/mysql.server /etc/init.d/mysqld
[root@chicken ~]# chmod +x /etc/init.d/mysqld
[root@chicken ~]# chkconfig --add mysqld
####启动MySQL服务#######
[root@chicken ~]# systemctl start mysqld
添加mysq操作指令关联系统
[root@chicken ~]# echo "PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile && . /etc/profile
####用户登录测试#####
[root@chicken ~]# mysql -u rootMySql主从复制
主配置
[root@chicken mysql]# cat << EOF >> /etc/ntp.conf
> server 127.127.1.0
> fudge 127.127.1.0 stratum 8
> EOF
[root@chicken mysql]# systemctl start ntpd
Ntp服务slave从配置
[root@chicken ~]# yum -y install ntpdate
[root@chicken ~]# ntpdate 192.168.223.124 ##主服务的IP地址主服务master配置
[root@chicken ~]# sed -i 's/# server_id = .*/server_id = 11/' /etc/my.cnf
[root@chicken ~]# sed -i '/server_id = 11/a\log_bin = master-bin' /etc/my.cnf
[root@chicken ~]# sed -i '/log_bin = master-bin/a\log-slave-updates = true' /etc/my.cnf
[root@chicken ~]# systemctl restart mysqld创建授权用户myslave
[root@chicken ~]# mysql -u root
mysql> grant replication slave on *.* to 'root'@'192.168.223.%' identified by '123456';
mysql> flush privileges;
mysql> show master status;
从服务器配置
[root@chicken ~]# sed -i 's/# server_id = .*/server_id = 22/' /etc/my.cnf
[root@chicken ~]# sed -i '/server_id = 22/a\relay-log = relay-log-bin' /etc/my.cnf
[root@chicken ~]# sed -i '/relay-log = relay-log-bin/a\relay-log-index = slave-relay-bin.index' /etc/my.cnf
####重启MySql服务######
[root@chicken ~]# systemctl restart mysqld
连接主服务器
[root@chicken ~]# mysql -u root
mysql> change master to master_host='192.168.160.51',master_user='myslave',master_password='123456',master_log_file='master-bin.000001',master_log_pos=120;
mysql> start slave;
mysql> show slave status\G;
MySQL读写分离
部署Java运行环境，上传安装包jdk-6u14-linux-x64.bin
[root@chicken ~]# chmod +x jdk-6u14-linux-x64.bin
[root@chicken ~]# ./jdk-6u14-linux-x64.bin
[root@chicken ~]# mv jdk1.6.0_14 /usr/local/jdk1.6添加Java运行环境变量
[root@chicken ~]# vim /etc/profile
####在export下面提添加变量######
export JAVA_HOME=/usr/local/jdk1.6
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$JAVA_HOME/lib:/$JAVA_HOME/jre/bin:$PATH:$HOME/bin
export AMOEBA_HOME=/usr/local/amoeba/
[root@chicken ~]# java -version部署amoeba，解压amoeba软件包并创建主目录
[root@chicken ~]# mkdir /usr/local/amoeba
[root@chicken ~]# tar zxf amoeba-mysql-binary-2.2.0.tar.gz -C /usr/local/amoeba
编辑主配置文件
[root@chicken ~]# cd /usr/local/amoeba/
[root@chicken amoeba]# vim conf/amoeba.xml
<property name="user">root</property> 客户端连接的用户
<property name="password">123456</property> 客户端连接密码
取消注释
<property name="writePool">server1</property> 写入数据池名称
<property name="readPool">server2</property> 读取数据池名称编辑数据库连接文件
[root@chicken amoeba]# vim conf/dbServers.xml
<property name="port">3306</property>
<property name="schema">test</property> 默认库 名称
<property name="user">root</property> 链接数据库用户名
<property name="password">123456</property> 链接数据库密码
修改ipaddress 127.0.0.1 为mysql 主和从的IP
<dbServer name="server1" parent="abstractServer">
<factoryConfig>
<!-- mysql ip -->
<property name="ipAddress">192.168.223.124</property>
</factoryConfig>
</dbServer>
<dbServer name="server2" parent="abstractServer">
<factoryConfig>
<!-- mysql ip -->
<property name="ipAddress">192.168.223.125</property>
</factoryConfig>
</dbServer>
启用amoeba
[root@chicken amoeba]# nohup ./bin/amoeba start 2>&1 &
查看端口
