本文章来给大家介绍linux中mysql 5.5二进制文件安装方法,有需要了解的朋友根据下面方法即可实现安装mysql5了.

1、创建相关目录用户,代码如下:

  1. su–root
  2. groupaddmysql
  3. useradd-gmysql-pxifenfei-s/bin/bash-mmysql-d/opt/mysql
  4. MYSQL_BASE=/opt/mysql
  5. mkdir-p$MYSQL_BASE/product/5.5
  6. mkdir-p$MYSQL_BASE/mysqldata
  7. mkdir-p$MYSQL_BASE/mysqllog
  8. mkdir-p/var/run/mysqld/
  9. chmod-R777$MYSQL_BASE
  10. chown-Rmysql:mysql$MYSQL_BASE
  11. chown-Rmysql:mysql/var/run/mysqld

2、环境变量配置,代码如下:

  1. exportMYSQL_BASE=/opt/mysql
  2. exportbasedir=$MYSQL_BASE/product/5.5
  3. exportdatadir=$MYSQL_BASE/mysqldata
  4. exportLD_LIBRARY_PATH=$basedir/lib:/lib:/usr/lib:/usr/local/lib
  5. exportTMPDIR=/tmp
  6. exportPATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
  7. exportPATH=$basedir:$basedir/bin:${PATH}:$LD_LIBRARY_PATH

3、调整mysql 用户系统限制（可选）

编辑文件:/etc/security/limits.conf 加入以下语句:

  1. mysqlsoftnproc2047
  2. mysqlhardnproc16384
  3. mysqlsoftnofile1024
  4. mysqlhardnofile65536

确认如下语句是否存在于/etc/pam.d/login,如果不存在请增加:

session required pam_limits.so

如果用户SHELL 用的是Bourne,Bash,或者Korn shell 修改/etc/profile,并增加如下内容,在SuSe 操作系统上,则需要修改/etc/profile.local,代码如下:

  1. if[$USER="mysql"];then
  2. if[$SHELL="/bin/ksh"];then
  3. ulimit-p16384
  4. ulimit-n65536
  5. else
  6. ulimit-u16384-n65536
  7. fi
  8. fi

4、安装数据库

4.1）解压数据库至/opt/mysql/product/5.5中

4.2）安装数据,代码如下:

  1. [mysql@localhost~]$cdproduct/5.5/scripts/
  2. [mysql@localhostscripts]$./mysql_install_db–basedir=$basedir–datadir=$datadir–user=mysql

4.3)设置my.cnf参数,代码如下:

  1. vi/etc/my.cnf
  2. [mysqladmin]
  3. socket=/var/run/mysqld/mysqld.sock
  4. [client]
  5. port=3306
  6. socket=/var/run/mysqld/mysqld.sock
  7. [mysqld]
  8. port=3306
  9. socket=/var/run/mysqld/mysqld.sock
  10. user=mysql

  29. thread_cache_size=32
  30. thread_concurrency=16
  31. query_cache_size=0M

  39. binlog_format=ROW
  40. max_binlog_size=300M
  41. slow_query_log=1
  42. slow_query_log_file=/opt/mysql/mysqllog/mysqld-slow

  78. write_buffer=8M
  79. [mysqlhotcopy]
  80. interactive-timeout
  81. [mysqld_safe]
  82. open-files-limit=8192

4.4）异常处理

4.4.1)直接通过mysqld_safe不能正常启动数据库,代码如下:

ln -s /opt/mysql/product/5.5 /usr/local/mysql

或者

ln -s /opt/mysql/product/5.5/bin/mysqld /usr/local/mysql/bin/mysqld

4.4.2）mysql_secure_installation不能正常执行.

1)执行:/opt/mysql/product/5.5/bin/mysql_secure_installation出现以下错误,解决方法（ln -s /var/run/mysqld/mysqld.sock /tmp/mysql.sock）

Enter current password for root (enter for none):

ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)

2)修改mysql_secure_installation 脚本的do_query 函数,推荐处理方法,代码如下:

  1. do_query(){
  2. echo“$1″>$command
  3. #sed‘s,^,>,’<$command#Debugging
  4. #mysql--defaults-file=$config<$command----此行修改如下：
  5. mysql--defaults-extra-file=$config<$command
  6. return$?
  7. }

5、添加开机启动服务

修改mysql.server文件,代码如下:

  1. basedir=/opt/mysql/product/5.5
  2. datadir=/opt/mysql/mysqldata
  3. [root@localhost~]#cp/opt/mysql/product/5.5/support-files/mysql.server/etc/init.d/mysqld
  4. [root@localhost~]#chkconfig–addmysqld
  5. [root@localhost~]#chkconfigmysqldon
  6. [root@localhost~]#chkconfig–listmysqld
  7. mysqld0:off1:off2:on3:on4:on5:on6:off
