Mysql 5.5以后使用了CMake进行安装，参考与以前的区别请参考：

接上文。

1：必要软件包

yum -y install  gcc gcc-c++ gcc-g77 autoconf automake zlib* fiex* libxml* ncurses-devel libmcrypt* libtool-ltdl-devel* make cmake

＃新增用户组
groupadd mysql

＃新增用户
useradd mysql -g mysql

＃新建数据库执行文件目录
mkdir -p /usr/local/mysql

＃新建数据库数据文件目录
mkdir -p /db/mysql/data

＃修改目录拥有者

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

chown -R mysql:mysql /db/mysql/data

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

chown -R mysql:mysql /db/mysql/data/.

＃编辑PATH搜索路径
vi /etc/profile
添加如下两行：

PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
export PATH

＃生效PATH搜索路径
source /etc/profile

＃安装编译源码所需的工具和库
yum -y install wget gcc-c++ ncurses-devel cmake make perl

＃进入源码压缩包下载目录
cd /usr/src

＃下载源码压缩包
wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.10.tar.gz/from/http://cdn.mysql.com/

＃解压缩源码包
tar -zxv -f mysql-5.6.10.tar.gz

＃进入解压缩源码目录

cd mysql-5.6.10

# 编译并安装

cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_SPHINX_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DMYSQL_DATADIR=/db/mysql/data \
-DMYSQL_USER=mysql \
-DMYSQL_TCP_PORT=3306 \
-DWITH_DEBUG=0

 
make && make install

红色部分表示禁用Debug模式。

＃复制配置文件
cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf

＃进入安装路径
cd /usr/local/mysql

＃执行配置脚本
scripts/mysql_install_db --user=mysql --datadir=/db/mysql/data

＃复制服务启动脚本
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql

＃启动MySQL服务
service mysql start

# 设置开机自动启动服务
chkconfig mysql on

>>>>>>>>>>>>>>>完成

如果发生如下错误：

[root@rekfan mysql]# service mysql restart
MySQL server PID file could not be found![失败]
Starting MySQL...The server quit without updating PID file (/usr/local/mysql/data/rekfan.pid).[失败]

黄海的问题解决办法是：

killall命令

killall命令杀死同一进程组内的所有进程。其允许指定要终止的进程的名称，而非PID。

# killall mysqld

再次查看mysqld进程：

ps -ef|grep mysqld

没有了！世界清静了。

运行 mysql

然后进入mysql> 提示符后，输入status;

查看安装情况。

mysql> status;

#表名全部为小写，避免出现大小写敏感

vi /etc/my.cnf 添加如下内容，解决大小写表名敏感问题。

lower_case_table_names=1

修改MySQL的root用户的密码以及打开远程连接

mysql

mysql> use mysql;

mysql> desc user;

mysql> GRANT ALL PRIVILEGES ON *.* TO root@"%" IDENTIFIED BY "root";    //为root添加远程连接的能力

mysql> update user set Password = password('123456') where User='root'; //设置root用户密码

mysql> select Host,User,Password from user where User='root';

mysql> flush privileges;

mysql> exit

附自动安装脚本如下：

vi installmysql.sh

chmod 777 installmysql.sh

./installmysql.sh

内容如下：

yum -y install wget gcc gcc-c++ gcc-g77 autoconf automake zlib* fiex* libxml* ncurses-devel libmcrypt* libtool-ltdl-devel* make cmake perl

groupadd mysql
useradd mysql -g mysql
mkdir -p /usr/local/mysql
mkdir -p /db/mysql/data

chown -R mysql:mysql /usr/local/mysql
chown -R mysql:mysql /db/mysql/data
chown -R mysql:mysql /usr/local/mysql/.
chown -R mysql:mysql /db/mysql/data/.

echo "PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:\$PATH" >> /etc/profile
echo "export PATH" >> /etc/profile
