MySQL多實例安裝

本文轉載自   查看原文   2016-04-08 21:50   1911    【數據庫 | Mysql】

 

1.安裝MySQL需要的依賴的包和編譯軟件
 
(1)安裝MySQL需要的依賴包
安裝MySQL之前，最好先安裝 MySQL需要的依賴包，不然后面會出現報錯，還得回來安裝 MySQL的依賴包。
  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)安裝編譯 MySQL需要的軟件
要安裝cmake編譯軟件：
  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.開始安裝MySQL
2.1 創建用戶mysql
  1. [root@mysql tools]# useradd mysql -s /sbin/nologin -M
  2. [root@mysql tools]# id mysql uid=501(mysql) gid=501(mysql) 組=501(mysql) [root@mysql tools]#
2.2 解壓編譯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
  21. #-- Build files have been written to: /home/oldboy/tools/mysql-5.5.32
  22. 提示，編譯時可配置的選項很多，具體可參考結尾附錄或官方文檔：
  23. make
  24. #[100%] Built target my_safe_process
  25. make install
  26. ln -s /application/mysql-5.5.32//application/mysql
  27. 如果上述操作未出現錯誤，則MySQL5.5.32軟件cmake方式的安裝就算成功了。
編譯過程中出現如下報錯，解決方法為：
  1. [root@mysql mysql-5.5.32]# rm CMakeCache.txt ###刪除這個文件，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 ##實例3306的數據文件
  6. ├──3307
  7. │??└── data ##實例3307的數據文件
  8. └── test
2.3 接着創建配置文件，將data.zip文件上傳到/(根)下，並且使用unzip命令解壓
  1. [root@mysql /]# unzip data.zip ##上傳到根下，加壓會替換上面創建的/data目錄
  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 ##實例的配置文件
  16. │??└── mysql ##實例的啟動文件
  17. ├──3307
  18. │??├── data

特別說明：
本文多實例啟動文件的啟動mysql服務實質命令：
mysqld_safe --defaults-file=/data  /3306/my.cnf 2>&1 /dev/null &
mysqld_safe --defaults-file=/data  /3307/my.cnf 2>&1 /dev/null &
 
本文多實例啟動文件的停止mysql服務實質命令：
mysqladmin -u root -p123456 -S /data/3306/mysql.sock shutdown
mysqladmin -u root -p123456 -S /data/3307/mysql.sock shutdown
 
2.4 修改數據文件/data 權限
  1. [root@mysql /]# chown -R mysql.mysql /data
  2. [root@mysql /]# find /data -type f -name "my.cnf"|xargs ls -l ##將my.cnf文件權限設置成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 ##由於mysql腳本中保存了登錄數據庫的密碼，需要將文件權限設置成700，只允許root,mysql訪問
  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命令全局使用路徑
     如果不為MySQL的命令配置全局路徑，就無法直接在命令行輸入mysql,這樣只能用全路徑/application/msyq/bin/mysql 這樣帶着路徑輸出會比較麻煩
 
2.5.1 配置 MySQL全局路徑方法
1.確認mysql命令所在路徑
  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路徑
  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 ##讓其生效
3. 最后檢查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 初始化數據庫
  1. cd /application/mysql/scripts/##注意和MySQL 5.1的路徑不同，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：
當初始化的過程中出現兩個OK時，表示初始化成功

3. 最后啟動mysql
  1. [root@mysql scripts]#/data/3306/mysql start
  2. StartingMySQL...
  3. [root@mysql scripts]#/data/3307/mysql start
  4. StartingMySQL...
  6. 查看是否啟動成功
  7. [root@mysql scripts]# netstat -lntup|grep mysql
  8. tcp 000.0.0.0:33060.0.0.0:* LISTEN 4614/mysqld
  9. tcp 000.0.0.0:33070.0.0.0:* LISTEN 5412/mysqld
4. 登錄mysql
mysql -uroot -p123456 -S /data/3306/mysql.sock
5. 多實例修改mysql 密碼
  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連接密碼，如果不修改否則在停庫的時候會報錯
  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數據庫
  1. [root@mysql scripts]#/data/3306/mysql stop
  2. StopingMySQL...
  3. [root@mysql scripts]#/data/3307/mysql stop
  4. StopingMySQL...
  5. [root@mysql scripts]#
 
新增一個多實例庫3308，操作命令如下
