[操作系统]MySQL多实例安装


 

1.安装MySQL需要的依赖的包和编译软件
 
(1)安装MySQL需要的依赖包
安装MySQL之前,最好先安装MySQL需要的依赖包,不然后面会出现报错,还得回来安装MySQL的依赖包。
  1. [root@Mysql-server tools]# yum install -y ncurses-devel libaio-devel
  2. [root@Mysql-server tools]# rpm -qa ncurses-devel libaio-devel
  3. ncurses-devel-5.7-4.20090207.el6.x86_64
  4. libaio-devel-0.3.107-10.el6.x86_64

 

(2)安装编译MySQL需要的软件
要安装cmake编译软件:
  1. [root@Mysql-server tools]# tar xf cmake-2.8.8.tar.gz
  2. [root@Mysql-server tools]# cd cmake-2.8.8
  3. [root@Mysql-server cmake-2.8.8]#./configure
  4. [root@mysql cmake-2.8.8]# gmake
  5. [root@mysql cmake-2.8.8]# gmake install

2.开始安装MySQL

2.1 创建用户mysql
  1. [root@mysql tools]# useradd mysql -s /sbin/nologin -M
  2. [root@mysql tools]# id mysqluid=501(mysql) gid=501(mysql) 组=501(mysql)[root@mysql tools]#

2.2 解压编译MySQL

  1. tar zxf mysql-5.5.32.tar.gz cd mysql-5.5.32
  2. cmake .-DCMAKE_INSTALL_PREFIX=/application/mysql-5.5.32 \
  3. -DMYSQL_DATADIR=/application/mysql-5.5.32/data \
  4. -DMYSQL_UNIX_ADDR=/application/mysql-5.5.32/tmp/mysql.sock \
  5. -DDEFAULT_CHARSET=utf8 \
  6. -DDEFAULT_COLLATION=utf8_general_ci \
  7. -DEXTRA_CHARSETS=gbk,gb2312,utf8,ascii \
  8. -DENABLED_LOCAL_INFILE=ON \
  9. -DWITH_INNOBASE_STORAGE_ENGINE=1 \
  10. -DWITH_FEDERATED_STORAGE_ENGINE=1 \
  11. -DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
  12. -DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \
  13. -DWITHOUT_PARTITION_STORAGE_ENGINE=1 \
  14. -DWITH_FAST_MUTEXES=1 \
  15. -DWITH_ZLIB=bundled \
  16. -DENABLED_LOCAL_INFILE=1 \
  17. -DWITH_READLINE=1 \
  18. -DWITH_EMBEDDED_SERVER=1 \
  19. -DWITH_DEBUG=0
  20. #-- Build files have been written to: /home/oldboy/tools/mysql-5.5.32
  21. 提示,编译时可配置的选项很多,具体可参考结尾附录或官方文档:
  22. make
  23. #[100%] Built target my_safe_process
  24. make install
  25. ln -s /application/mysql-5.5.32//application/mysql
  26. 如果上述操作未出现错误,则MySQL5.5.32软件cmake方式的安装就算成功了。

编译过程中出现如下报错,解决方法为:

  1. [root@mysql mysql-5.5.32]# rm CMakeCache.txt ###删除这个文件,重新cmake

 

 
  1. [root@mysql mysql-5.5.32]# mkdir -p /data/{3306,3307}/data
  2. [root@mysql mysql-5.5.32]# tree /data/
  3. /data/
  4. ├──3306
  5. │??└── data ##实例3306的数据文件
  6. ├──3307
  7. │??└── data ##实例3307的数据文件
  8. └── test

2.3 接着创建配置文件,将data.zip文件上传到/(根)下,并且使用unzip命令解压

  1. [root@mysql /]# unzip data.zip ##上传到根下,加压会替换上面创建的/data目录
  2. Archive: data.zip
  3. inflating: data/3306/my.cnf
  4. inflating: data/3306/mysql
  5. inflating: data/3307/my.cnf
  6. inflating: data/3307/mysql
  7. [root@mysql /]# tree /data
  8. data/ data.zip
  9. [root@mysql /]# tree data
  10. data/ data.zip
  11. [root@mysql /]# tree data/
  12. data/
  13. ├──3306
  14. │??├── data
  15. │??├── my.cnf ##实例的配置文件
  16. │??└── mysql ##实例的启动文件
  17. ├──3307
  18. │??├── data
  19. │??├── my.cnf ##实例的配置文件
  20. │??└── mysql ##实例的启动文件
  21. └── test

特别说明:
本文多实例启动文件的启动mysql服务实质命令:
mysqld_safe --defaults-file=/data /3306/my.cnf 2>&1 /dev/null &
mysqld_safe --defaults-file=/data /3307/my.cnf 2>&1 /dev/null &

 
本文多实例启动文件的停止mysql服务实质命令:

mysqladmin -u root -p123456 -S /data/3306/mysql.sock shutdown
mysqladmin -u root -p123456 -S /data/3307/mysql.sock shutdown
 
2.4 修改数据文件/data 权限
  1. [root@mysql /]# chown -R mysql.mysql /data
  2. [root@mysql /]# find /data -type f -name "my.cnf"|xargs ls -l ##将my.cnf文件权限设置成644
  3. -rw-r--r--.1 mysql mysql 189910月292013/data/3306/my.cnf
  4. -rw-r--r--.1 mysql mysql 190110月292013/data/3307/my.cnf
  5. [root@mysql /]# find /data -type f -name "mysql"|xargs ls -l ##由于mysql脚本中保存了登录数据库的密码,需要将文件权限设置成700,只允许root,mysql访问
  6. -rw-r--r--.1 mysql mysql 13077月152013/data/3306/mysql
  7. -rw-r--r--.1 mysql mysql 13077月212013/data/3307/mysql
  8. [root@mysql /]# find /data -type f -name "mysql"|xargs chmod 700
  9. [root@mysql /]# find /data -type f -name "mysql"|xargs ls -l
  10. -rwx------.1 mysql mysql 13077月152013/data/3306/mysql
  11. -rwx------.1 mysql mysql 13077月212013/data/3307/mysql

2.5 配置MySQL命令全局使用路径

     如果不为MySQL的命令配置全局路径,就无法直接在命令行输入mysql,这样只能用全路径/application/msyq/bin/mysql 这样带着路径输出会比较麻烦
 
2.5.1 配置MySQL全局路径方法
1.确认mysql命令所在路径
  1. [root@mysql /]# ll /application/mysql/bin/mysql
  2. -rwxr-xr-x.1 root root 53453564月816:05/application/mysql/bin/mysql

2. 修改PATH路径

  1. [root@mysql /]# tail -1/etc/profile
  2. export PATH=/application/mysql/bin:$PATH ##添加如下行
  3. [root@mysql /]# source /etc/profile ##让其生效

3. 最后检查PATH

  1. [root@mysql /]# echo $PATH
  2. /application/mysql/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

2.6 初始化数据库

  1. cd /application/mysql/scripts/##注意和MySQL 5.1的路径不同,MySQL 5.1 不在mysql/bin下
  2. ./mysql_install_db --basedir=/application/mysql --datadir=/data/3306/data/--user=mysql
  3. ./mysql_install_db --basedir=/application/mysql --datadir=/data/3307/data/--user=mysql

注意:

当初始化的过程中出现两个OK时,表示初始化成功


3. 最后启动mysql
  1. [root@mysql scripts]#/data/3306/mysql start
  2. StartingMySQL...
  3. [root@mysql scripts]#/data/3307/mysql start
  4. StartingMySQL...
  5. 查看是否启动成功
  6. [root@mysql scripts]# netstat -lntup|grep mysql
  7. tcp 000.0.0.0:33060.0.0.0:* LISTEN 4614/mysqld
  8. tcp 000.0.0.0:33070.0.0.0:* LISTEN 5412/mysqld

4. 登录mysql
mysql -uroot -p123456 -S /data/3306/mysql.sock


5. 多实例修改mysql 密码
  1. [root@mysql scripts]# mysqladmin -uroot password 123456 -S /data/3306/mysql.sock
  2. [root@mysql scripts]# mysqladmin -uroot password 123456 -S /data/3307/mysql.sock

6. 修改配置文件中的mysql连接密码,如果不修改否则在停库的时候会报错

  1. [root@mysql scripts]# sed -i '13 s#oldboy#123456#g'/data/3306/mysql
  2. [root@mysql scripts]# sed -n '13p'/data/3306/mysql
  3. mysql_pwd="123456"
  4. [root@mysql scripts]# sed -i '13 s#oldboy#123456#g' /data/3307/mysql[root@mysql scripts]# sed -n '13p' /data/3307/mysql mysql_pwd="123456"[root@mysql scripts]#

7.停止mysql数据库

  1. [root@mysql scripts]#/data/3306/mysql stop
  2. StopingMySQL...
  3. [root@mysql scripts]#/data/3307/mysql stop
  4. StopingMySQL...
  5. [root@mysql scripts]#

 

新增一个多实例库3308,操作命令如下
