如何搭建直播系统LNMP环境,下面先教如何配置mysql。

一、前期准备

1.关闭防火墙及selinux

service iptables stop

chkconfig iptables off

setenforce 0

vi /etc/sysconfig/selinux

   SELINUX=disabled      #enforcing改为disabled

2.依赖包安装

yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel openldap-clients openldap-servers make  libtool* git tree bison pcre-devel perl gd gd-devel

3.安装libiconv(支持编码转换为函数)

tar xf libiconv-1.14.tar.gz

cd libiconv-1.14/

./configure --prefix=/usr/local make && make install

 

4.安装libmcrypt (加密算法扩展库,支持DES, 3DES, RIJNDAEL, Twofish, IDEA, GOST, CAST-256, ARCFOUR, SERPENT, SAFER+等算法)

tar xf libmcrypt-2.5.8.tar.gz

cd libmcrypt-2.5.8

./configuremake && make install

cd libltdl/

./configure --enable-ltdl-install    #加载动态库make && make install

 

5.安装mhash(Mhash是基于离散数学原理的不可逆向的php加密方式扩展库,其在默认情况下不开启。 mhash的可以用于创建校验数值,消息摘要,消息认证码,以及无需原文的关键信息保存)

tar xf mhash-0.9.9.9.tar.bz2

cd mhash-0.9.9.9

./configure

make && make install

 

6.安装mcript(mcrypt 是 php 里面重要的加密支持扩展库,Mcrypt扩展库可以实现加密解密功能,就是既能将明文加密,也可以密文还原。)

cd /usr/local/src

tar zxvf mcrypt-2.6.8.tar.gz cd mcrypt-2.6.8/ export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH    #暂时生效

./configure

make && make install

 

7.亦可以通过以下两种方法增加库文件

ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la 

ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so 

ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4

ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8

ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a 

ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la 

ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so 

ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2

ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1

ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config

 

vim /etc/ld.so.conf

    /usr/local/lib/     

ldconfig

8.安装cmake (MySQL从5.5版本开始,通过./configure进行编译配置方式已经被取消,取而代之的是cmake工具)

tar xf cmake-3.4.1.tar.gz

cd cmake-3.4.1

./bootstrap

make && make install

二、MySQL安装

1.新增mysql用户

groupadd -r mysql

useradd -r -g mysql mysql

2.新建MySQL所需目录

mkdir -p /usr/local/mysql

mkdir -p /data/mysqldb

3.编译安装

tar xf mysql-5.6.23.tar.gz

cd mysql-5.6.23

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1-DMYSQL_DATADIR=/data/mysqldb -DMYSQL_TCP_PORT=3306 -DENABLE_DOWNLOADS=1-DSYSCONFDIR=/etc -DWITH_SSL=system -DWITH_ZLIB=system -DWITH_LIBWRAP=0

make&& make install

4.修改mysql目录权限

cd /usr/local/mysql

chown -R mysql:mysql .

cd /data/mysqldb

chown -R mysql:mysql .

 

5.初始化mysql数据库

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

6.编译修改/etc/my.cnf

[mysql]

 # CLIENT #port                           = 3306socket                         = /data/mysqldb/mysql.sock 

[mysqld]

 # GENERAL #user                           = mysqldefault-storage-engine         = InnoDBsocket                         = /data/mysqldb/mysql.sockpid-file                       = /data/mysqldb/mysql.pid

 # MyISAM #key-buffer-size                = 32Mmyisam-recover                 = FORCE,BACKUP

 # SAFETY #max-allowed-packet             = 16Mmax-connect-errors             = 1000000

 # DATA STORAGE #datadir                        = /data/mysqldb/

 # BINARY LOGGING #log-bin                        = /data/mysqldb/mysql-binexpire-logs-days               = 14sync-binlog                    = 1

 # REPLICATION #skip-slave-start               = 1relay-log                      = /data/mysqldb/relay-binslave-net-timeout              = 60

 # CACHES AND LIMITS #tmp-table-size                 = 32Mmax-heap-table-size            = 32Mquery-cache-type               = 0query-cache-size               = 0max-connections                = 500thread-cache-size              = 50open-files-limit               = 65535table-definition-cache         = 4096table-open-cache               = 4096

 # INNODB #innodb-flush-method            = O_DIRECTinnodb-log-files-in-group      = 2innodb-log-file-size           = 64Minnodb-flush-log-at-trx-commit = 1innodb-file-per-table          = 1innodb-buffer-pool-size        = 592M

 # LOGGING #log-error                      = /data/mysqldb/mysql-error.loglog-queries-not-using-indexes  = 1slow-query-log                 = 1slow-query-log-file            = /data/mysqldb/mysql-slow.log

7.复制MySQL启动文件及其命令加入PATH

cp support-files/mysql.server /etc/init.d/mysqld   

vim /etc/profile.d/mysql.sh

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

    export PATH

source /etc/profile.d/mysql.sh

8.启动MySQL并增加启动项

service mysqld start 

chkconfig  mysqld on

9.设置MySQL登录权限

drop user ''@localhost;drop user ''@hostname;update mysql.user set password=password('*******');flush privileges;

到这里,MySQL编译完成
