CentOS6.5源码安装mysql-5.5.21

本文参考自 http://www.cnblogs.com/ShanFish/p/6531365.html，但不局限于它。

一. 卸载旧版本

.检查是否安装mysql组件
# rpm -qa | grep mysql

.如果有，就卸载
# rpm -ev mysql-libs-5.1.-.el6.x86_64
# rpm -ev mysql-libs-5.1.-.el6.x86_64 --nodeps  //强力删除

.删除相关目录
# whereis mysql
# find / -name 'mysql'

//在卸载掉第2步的mysql组件后，下面的目录应该就被删除了（如果还存在的话，手动删除）
# rm -rf /usr/share/mysql
# rm -rf /usr/lib64/mysql

二. 编译安装

1.安装编译所需的软件包

yum -y install make gcc-c++ cmake bison-devel ncurses-devel

2.下载解压
终端的文件下载地址我也没有，可以去这个网址 http://download.csdn.net/download/lhat_7/9863714 下载压缩包

tar xvf mysql-5.5..tar.gz
cd mysql-5.5.

3.编译安装

cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DSYSCONFDIR=/etc \
-DWITH_MYISAM_STORAGE_ENGINE= \
-DWITH_INNOBASE_STORAGE_ENGINE= \
-DWITH_MEMORY_STORAGE_ENGINE= \
-DWITH_READLINE= \
-DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock \
-DMYSQL_TCP_PORT= \
-DENABLED_LOCAL_INFILE= \
-DWITH_PARTITION_STORAGE_ENGINE= \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci

make && make install

报错1：

-- MySQL 5.5.
Warning: Bison executable not found in PATH
-- Configuring done
CMake Warning (dev) in sql/CMakeLists.txt:
  Policy CMP0022 is not set: INTERFACE_LINK_LIBRARIES defines the link
  interface.  Run "cmake --help-policy CMP0022" for policy details.  Use the
  cmake_policy command to set the policy and suppress this warning.

  Target "mysqld" has an INTERFACE_LINK_LIBRARIES property which differs from
  its LINK_INTERFACE_LIBRARIES properties.

  INTERFACE_LINK_LIBRARIES:

    -lpthread;sql;mysys

  LINK_INTERFACE_LIBRARIES:

    rt

This warning is for project developers.  Use -Wno-dev to suppress it.

-- Generating done

百度之后得到答案  yum install bison

重新编译前要清缓存

make clean
rm -f CMakeCache.txt
rm -rf /etc/my.cnf

再次编译有报错2：

CMake Warning (dev) in sql/CMakeLists.txt:
  Policy CMP0022 is not set: INTERFACE_LINK_LIBRARIES defines the link
  interface.  Run "cmake --help-policy CMP0022" for policy details.  Use the

  Target "mysqld" has an INTERFACE_LINK_LIBRARIES property which differs from
  its LINK_INTERFACE_LIBRARIES properties.

  INTERFACE_LINK_LIBRARIES:

    -lpthread;sql;mysys

  LINK_INTERFACE_LIBRARIES:

    rt

This warning is for project developers.  Use -Wno-dev to suppress it.

解决方法：没找到解决方法（我没管它，直接下一步了）

make && make install

这是一个漫长的过程，等待...

三. 配置MySQL

1. 设置权限

查看是否有mysql用户和用户组

cat /etc/passwd
cat /etc/group

如果没有就添加用户和用户组

groupadd mysql
useradd -g mysql mysql

修改 /usr/local/mysql 权限

chown -R mysql:mysql /usr/local/mysql

2.初始化mysql

执行初始化配置脚本，创建系统自带的数据库和表

cd /usr/local/mysql
scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql

3.添加mysql服务

如果/etc目录下之前存在my.cnf文件，将其重命名作为备份

mysql服务启动时，会优先在 /etc 目录下查找 my.cnf

cp support-files/mysql.server /etc/init.d/mysql
chkconfig mysql on
service mysql start

4.配置mysql用户

把 /usr/local/mysql/bin 目录添加到PATH里，这样在任何地方都能直接调用该目录下的命令了。

vim /etc/profile
//在 /etc/profile 的末尾添加
export PATH=$PATH/usr/local/mysql/bin
//关闭文件，运行下面的命令，使配置立即生效
source /etc/profile

mysql启动成功后，root用户默认没有密码，我们需要为它设置密码

mysqladmin -uroot -p password <new_password>

最后使用密码登录
