1 安装JDK

1.1 下载JDK1.8

[root@localhost~]# wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u112-b15/jdk-8u112-linux-x64.tar.gz

1.2 解压JDK1.8

[root@localhost~]# tar -zxvf jdk-8u112-linux-x64.tar.gz

1.3 设置环境变量

[root@localhost~]# vi /etc/profile

在profile中添加如下内容:

set java environment
export JAVA_HOME=/zxk175/jdk/8/jdk1.8.0_112
export JRE_HOME=${JAVA_HOME}/jre  
export PATH=${JAVA_HOME}/bin:$PATH  
export CLASSPATH=.:${JAVA_HOME}/lib:${JAVA_HOME}/jre/lib  

1.4 让配置生效

[root@localhost ~]# source /etc/profile

1.5 测试是否成功

[root@localhost ~]# java -version

输出以下内容则配置成功
java version "1.8.0_112"
Java(TM) SE Runtime Environment (build 1.8.0_112-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.112-b15, mixed mode)

2 安装Tomcat

2.1 下载Tomcat8

[root@localhost ~]# wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-8/v8.5.13/bin/apache-tomcat-8.5.13.tar.gz

2.2 解压Tomcat8

[root@localhost ~]# tar -xzvf apache-tomcat-8.5.12.tar.gz

2.3 启动Tomcat8

[root@localhost ~]# ./startup.sh

输出以下内容则启动成功
Using CATALINA_BASE:   /zxk175/tomcats/tomcat8
Using CATALINA_HOME:   /zxk175/tomcats/tomcat8
Using CATALINA_TMPDIR: /zxk175/tomcats/tomcat8/temp
Using JRE_HOME:        /zxk175/jdk/1.8/jdk1.8.0_112/jre
Using CLASSPATH:       /zxk175/tomcats/tomcat8/bin/bootstrap.jar:/zxk175/tomcats/tomcat8/bin/tomcat-juli.jar
Tomcat started.

3 安装Nginx

3.1 下载Nginx

[root@localhost ~]# wget http://mirrors.sohu.com/nginx/nginx-1.10.3.tar.gz

3.2 编译Nginx

3.2.1 安装编译软件

[root@localhost ~]# yum -y install gcc gcc-c++ make libtool zlib zlib-devel openssl openssl-devel pcre pcre-devel

3.2.2 添加用户

[root@localhost src]# groupadd -r nginx
[root@localhost src]# useradd -r -g nginx nginx

3.2.3 编译Nginx

[root@localhost ~]# cd nginx-1.10.3 [root@localhost ~]#./configure
--prefix=/zxk175/nginx/nginx
--user=nginx
--group=nginx
--with-http_ssl_module
--with-http_flv_module
--with-http_gzip_static_module
--with-http_stub_status_module
[root@localhost ~]# make

3.2.4 安装Nginx

[root@localhost ~]# make install

3.2.5 配置Nginx

3.2.5.1 查看Nginx信息

[root@localhost ~]# /zxk175/nginx/nginx/sbin/nginx -V

3.2.5.2 修改nginx.conf

nginx.conf proxy.conf zxk175.conf weixin.conf

4 安装MySQL

4.0 准备工作

4.0.1 卸载自带的MySQL

[root@localhost src]# yum remove mysql mysql-server mysql-libs compat-mysql51 [root@localhost src]# rm -rf /var/lib/mysql [root@localhost src]# rm -rf /etc/my.cnf

4.0.2 c++: internal compiler error: Killed (program cc1plus)

原因:内存不足, 在Linux下增加临时swap空间 step 1: [root@localhost src]# dd if=/dev/zero of=/home/swap bs=1024 count=500000 注释:of放置swap的空间; count增加的大小,bs是块的大小,总共空间是bs*count=500M step 2: [root@localhost src]# mkswap /home/swap 注释:把刚才空间格式化成swap格式 step 3: [root@localhost src]# swapon /home/swap 注释:使用刚才创建的swap空间

如果想关闭刚开辟的swap空间,只需命令:[root@localhost src]# swapoff

4.1 下载MySQL

[root@localhost src]# wget http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.35.tar.gz

4.2 解压MySQL

[root@localhost ~]# tar -xzvf mysql-5.6.35.tar.gz

4.3 编译MySQL

4.3.0 添加用户

[root@localhost ~]# groupadd mysql [root@localhost ~]# useradd -r -g mysql mysql [root@localhost ~]# id mysql

4.3.1 安装编译软件

[root@localhost ~]# yum install -y gcc-c++ gdb cmake pcre ncurses-devel bison bison-devel

4.3.2 编译MySQL

[root@localhost ~]# cd mysql-5.6.35 [root@localhost ~]# cmake
--DCMAKE_INSTALL_PREFIX=/zxk175/mysql
--DMYSQL_DATADIR=/zxk175/mysql/data
--DSYSCONFDIR=/zxk175/mysql
--DWITH_INNOBASE_STORAGE_ENGINE=1
--DWITH_PARTITION_STORAGE_ENGINE=1
--DMYSQL_UNIX_ADDR=/zxk175/mysql/sock/mysql.sock
--DMYSQL_TCP_PORT=3306
--DDEFAULT_CHARSET=utf8
--DDEFAULT_COLLATION=utf8_general_ci
[root@localhost ~]# make -j 4

4.3.3 安装MySQL

[root@localhost ~]# make install

4.3.4 改变目录所有者

[root@localhost ~]# chown -R mysql.mysql /zxk175/mysql

4.3.5 加入PATH路径

[root@localhost ~]# vi /etc/profile  

文件尾部插入以下内容
PATH=/zxk175/mysql/bin:/zxk175/mysql/lib:$PATH
export PATH  

[root@localhost ~]# source /etc/profile    

4.3.6 执行初始化配置脚本,创建系统自带的数据库和表

[root@localhost ~]# cd /zxk175/mysql [root@localhost ~]# scripts/mysql_install_db --basedir=/zxk175/mysql --datadir=/zxk175/mysql/data --user=mysql

4.3.7 添加服务,拷贝服务脚本到init.d目录,并设置开机启动

4.3.9.1 赋予任何主机访问数据的权限并刷新权限 mysql> grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option; mysql> flush privileges; mysql> exit;

退出MySQL服务器,就可以在其它任何主机上以root身份登录
