CentOS 5.5下安装MySQL 5.5全过程分享

时间:2021-05-25

打开终端

切换到根目录

[shell@localhost ~]# su -安装Mysql5.5之前先卸载CentOS自带的Mysql5.0。

[root@localhost ~]# yum remove mysql

安装cmake

下载cmake源码包cmake-2.8.5.tar.gz

[root@localhost ~]# wget http:///Downloads/MySQL-5.5/mysql-5.5.27.tar.gz解压

[root@localhost ~]# cd /usr/local/[root@localhost local]# tar xzvf mysql-5.5.27.tar.gz[root@localhost local]# cd mysql-5.5.27

cmake运行

[root@localhost mysql-5.5.27]# cmake .

报错:

-- Could NOT find Curses (missing: CURSES_LIBRARY CURSES_INCLUDE_PATH) CMake Error at cmake/readline.cmake:82 (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:126 (FIND_CURSES) cmake/readline.cmake:216 (MYSQL_USE_BUNDLED_LIBEDIT) CMakeLists.txt:250 (MYSQL_CHECK_READLINE) -- Configuring incomplete, errors occurred!

解决办法:

[root@localhost mysql-5.5.27]# rm CMakeCache.txt [root@localhost mysql-5.5.27]# yum -y install ncurses-devel*

重新cmake运行

[root@localhost mysql-5.5.27]# cmake .还是有个警告

Warning: Bison executable not found in PATH有一个警告,也解决了它,缺少Bison就安装一下

[root@localhost mysql-5.5.27]# yum install bison

再次运行,没有报错

[root@localhost mysql-5.5.27]# cmake .在编译安装前,可以设置安装的配置选项

[root@localhost mysql-5.5.27]# ./configure --help根据帮助信息选择自己需要设置的选项,当然也可以跳过这步,按默认设置


#开始编译安装,时间有点稍长...

[root@localhost mysql-5.5.27]# make && make install完成编译安装

进入安装目录,将程序二进制的所有权改为root,数据目录的所有权改为mysql用户,更新授权表

[root@localhost mysql-5.5.27]# cd /usr/local/mysql[root@localhost mysql]# chown -R root . [root@localhost mysql]# chown -R mysql . [root@localhost mysql]# chgrp -R mysql . [root@localhost mysql]# scripts/mysql_install_db --user=mysql 初始化数据库[root@localhost mysql]# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data 安全启动mysql

[root@localhost mysql]# ./bin/mysqld_safe --user=mysql关闭mysql

[root@localhost mysql]# ./bin/mysqladmin -u root shutdown -p默认密码为空方便调用,为mysql设置一个软链接[root@localhost ~]# ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql

其他设置处理:

设置选项文件,将配置文件拷贝到/etc下

[root@localhost mysql]# cp support-files/my-medium.cnf /etc/mysql.cnf 设置开机自启动[root@localhost mysql]# cp support-files/mysql.server /etc/init.d/mysql [root@localhost mysql]# chmod +x /etc/init.d/mysql [root@localhost mysql]# chkconfig –add mysqld[root@localhost mysql]# chkconfg mysqld on

现在可以通过服务来启动和关闭Mysql服务器

[root@localhost ~]# service mysql start [root@localhost ~]# service mysql shutdown

连接服务器

[root@localhost ~]# mysql -u root -pyourpasswordWelcome to the MySQL monitor. Commands end with ; or \g.Your MySQL connection id is 3 to server version: 5.5.27 Source distributinoType 'help;' or '\h' for help. Type '\c' to clear the buffer.mysql> ...mysql> 提示符告诉你mysql准备为你输入命令。

至此MySQL已经正常安装并可以使用
