linux系统下mysql的安装步骤

这篇文章主要讲解了“linux系统下mysql的安装步骤”，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习“linux系统下mysql的安装步骤”吧！

1：首先下载mysql 二进制安装文件
mysql-5.6.17.tar.gz
存放目录/u01/soft/mysql-5.6.17.tar.gz
tar -xf mysql-5.6.17.tar.gz
cd mysql-5.6.17
进行cmake，但是提示没有安装cmake

2:下载cmake
cmake-2.8.10.2.tar.gz
tar -xf cmake-2.8.10.2.tar.gz
./configure
make && make install

3:进行cmake
    先创建mysql 安装目录以及数据文件存放目录
        mkdir -p /mysql
        mkdir -p /mysql/data
    同时需要创建mysql 账号
        useradd mysql
        passwd mysql
    再进行目录授权：
        chown -R mysql:mysql /mysql
   cd mysql-5.6.17
 cmake \
        -DCMAKE_INSTALL_PREFIX=/mysql/ \               //mysql软件安装的根目录
        -DMYSQL_DATADIR=/mysql/data \                   //mysql 数据文件存放目录
        -DSYSCONFDIR=/etc \                                    //mysql 配置文件(my.cnf)目录
        -DWITH_MYISAM_STORAGE_ENGINE=1 \         //存储引擎选项
        -DWITH_INNOBASE_STORAGE_ENGINE=1 \    //以启用InnoDB、引擎支持：
        -DWITH_MEMORY_STORAGE_ENGINE=1 \
        -DWITH_READLINE=1 \                                 
        -DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock \   
        -DMYSQL_TCP_PORT=3306 \
        -DENABLED_LOCAL_INFILE=1 \                          //启用加载本地数据
        -DWITH_PARTITION_STORAGE_ENGINE=1 \        
        -DEXTRA_CHARSETS=all \
        -DDEFAULT_CHARSET=utf8 \                           //默认字符集
        -DDEFAULT_COLLATION=utf8_general_ci          //字符集校对
    进行编译，编译时报错如下：
            heck size of wctype_t - done
            -- Check size of wint_t
            -- Check size of wint_t - done
            -- Could NOT find Curses (missing:  CURSES_LIBRARY CURSES_INCLUDE_PATH) 
                CMake Error at cmake/readline.cmake:85 (MESSAGE):
                  Curses library not found.  Please install appropriate package,               remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev, on Redhat and derivates it is ncurses-devel.
            Call Stack (most recent call first):
              cmake/readline.cmake:128 (FIND_CURSES)
              cmake/readline.cmake:202 (MYSQL_USE_BUNDLED_EDITLINE)
              CMakeLists.txt:411 (MYSQL_CHECK_EDITLINE)
    这个报错是提示缺少ncurses-devel依赖包
    进行下载：ncurses-devel-5.7-3.20090208.el6.x86_64.rpm
        rpm -ivh ncurses-devel-5.7-3.20090208.el6.x86_64.rpm 
        warning: ncurses-devel-5.7-3.20090208.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY
        Preparing...                ########################################### [100%]
       1:ncurses-devel          ########################################### [100%]
    同时rm -rf CMakeCache.txt 然后进行重新cmake
        完成之后，进行make &&　make install 进行mysql 安装
        - Installing: /mysql/man/man1/msql2mysql.1
        -- Installing: /mysql/man/man8/mysqld.8
        -- Installing: /mysql/support-files/solaris/postinstall-solaris
        算安装完成了，接下来就需要进行配置
4： 进入到mysql的安装目录，/mysql下：进行mysql 数据库初始化
        scripts/mysql_install_db --basedir=mysql --datadir=/mysql/data --user=mysql  //初始化mysql数据库
      但是报错
        [root@db_test scripts]# ./mysql_install_db  --basedir=mysql --datadir=/mysql/data --user=mysql
            FATAL ERROR: Could not find ./bin/my_print_defaults
               cd  /u01/soft/mysql-5.6.17/support-files
         
            cp  my-default.cnf /usr/local/mysql/my.cnf //copy配置文件

            [root@db_test support-files]# chown -R mysql:mysql /mysql
        vi /my.cnf 添加以下内容
    [mysqld]
    basedir = /mysql          
    datadir = /mysql/data  
    log-error = /mysql/mysql_error.log          
    pid-file = /mysql/mysql.pid          
    user = mysql
    tmpdir = /tmp 

    初始化mysql数据库
[root@db_test scripts]# ./mysql_install_db  --basedir=/mysql --datadir=/mysql/data --user=mysql
