安装MySql步骤如下：
- 依赖包检查安装
- 配置防火墙
- 配置hosts文件
- 配置sysctl.cnf
- 检查是否安装mysql 如果有卸载掉（指的是没有用的mysql）
- 创建用户属组
- 创建相应目录并修改权限
- 上传压缩包并解压
- 配置环境变量
- Cmake编译 make && make install
- 初始化数据库
- 开启服务并登陆，设置开机启动
1. 依赖包检查安装
rpm -q cmake make gcc gcc-c++ bison ncurses ncurses-devel openssl openssl-devel boost-devel
yum -y install cmake make gcc gcc-c++ bison ncurses ncurses-devel openssl openssl-devel
注意这里的boot版本需要1.59的 如果直接yum安装版本是不对的（1.53）
2. 配置防火墙
service iptables stop
chkconfig iptables off
vim /etc/selinux/config
修改为SELINUX=disabled
3. 配置hosts文件
vim /etc/hosts #看下hosts文件有没有配置过，没有的话 增加IP和 主机名，不然编译时候会报错提示hostsname识别不了的错误
4. 配置sysctl.cnf (因为只是做测试，暂时不设置，需要可以去百度，我初学也不大董怎么设置最优)
5. 检查是否安装mysql 如果有卸载掉（指的是没有用的mysql）
[root@lscj ~]# rpm -qa| grep mysql
mysql-libs-5.1.71-1.el6.x86_64
[root@lscj ~]# rpm -e mysql-libs-5.1.71-1.el6.x86_64
6. 创建用户属组，配置环境变量
groupadd mysql
useradd -g mysql mysql
passwd mysql
id mysql
su - mysql
vim .bash_profile
MYSQL_HOME=/u01/app/mysql/mysql3306
PATH=$PATH:$MYSQL_HOME/bin
export PATH MYSQL_HOME
source .bash_profile
7. 创建相应目录并修改权限
mkdir -p /u01/app/mysql/mysql3306
mkdir -p /u01/app/mysql/mysql3306/data
mkdir -p /u01/app/mysql/mysql3306/log/iblog
mkdir -p /u01/app/mysql/mysql3306/log/binlog
mkdir -p /u01/app/mysql/mysql3306/run
mkdir -p /u01/app/mysql/mysql3306/temp
chown -R mysql:mysql /u01/app/mysql
8. 上传压缩包并解压
yum -y install lrzsz ftp工具
mysql安装包上传到/tmp/mysql下
tar -zxvf mysql-5.6.40.tar.gz
9. Cmake编译 make && make install
[mysql@lscj ~]$ cd /tmp/mysql/mysql-5.6.40
cmake \
-DCMAKE_INSTALL_PREFIX=/u01/app/mysql/mysql3306 \
-DINSTALL_DATADIR=/u01/app/mysql/mysql3306/data \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DEXTRA_CHARSETS=all \
-DWITH_SSL=yes \
-DWITH_EMBEDDED_SERVER=1 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DMYSQL_UNIX_ADDR=/u01/app/mysql/mysql3306/run/mysql.sock \
-DMYSQL_TCP_PORT=3306 \
-DENABLED_LOCAL_INFILE=1 \
-DSYSCONFDIR=/etc \
-DWITH_READLINE=on
make && make install
之前的操作是root用户执行的，下面我们要进行赋权操作
chmod –R mysql:mysql /u01/app/mysql
11. 初始化数据库
./scripts/mysql_install_db --defaults-file=/u01/app/mysql/mysql3306/my.cnf --datadir=/u01/app/mysql/mysql3306/data --basedir=/u01/app/mysql/mysql3306 --user=mysql
12. 检查数据库初始化是否成功
cd到我们之前设置的 datadir路径下，看对应的文件夹是否生成
13.服务
cp $MYSQL_HOME/support-files/mysql.server /etc/init.d/mysql
这样以后就可以直接 service mysql status|start|stop 管理服务
最后附上我的参数文件信息
