安装nginx(源码安装，需要gcc编译器)
1.下载
cd /usr/local
mkdir nginx
cd nginx
wget http://nginx.org/download/nginx-1.13.7.tar.gz
tar -xvf nginx-1.13.7.tar.gz
2.首先安装 gcc、pcre、zlib、openssl
yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel
3.安装nginx
./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module
4.编译源文件
make
make install
5.启动nginx
[root@localhost nginx-1.12.0]# cd /usr/local/nginx/sbin ##进入目录下
[root@localhost sbin]# pwd
/usr/local/nginx/sbin
[root@localhost sbin]# ./nginx ## 开启
[root@localhost sbin]# netstat -antlp ## 查看端口号
6.测试
可以打开浏览器，输入本机ip或localhost，进入nginx主页即安装成功
或者使用命令测试
[root@localhost sbin]# curl -I localhost ## 测试
HTTP/1.1 200 OK
Server: nginx/1.12.0 ## 环境版本
Date: Tue, 09 Jan 2018 06:20:20 GMT
Content-Type: text/html
Content-Length: 612
Last-Modified: Tue, 09 Jan 2018 06:14:15 GMT
Connection: keep-alive
ETag: "5a545db7-264"
Accept-Ranges: bytes
7.优化
通过上面显示，访问者可以得到服务器版本号，不安全
而且可以查看安装文件，占据空间较大
## 通过du命令查看文件大小
[root@localhost sbin]# du nginx
5.15M nginx
主要原因是安装时，默认安装了Debug模式
但实际服务器是不需要调式功能，可以把它去掉
8.准备工作
删除压缩包重新解压
关闭nginx服务
[root@localhost sbin]# ./nginx -s stop ## 关闭nginx服务
a.修改nginx.h
[root@localhost sbin]# cd nginx-1.12.0/ ## 进入源码目录
[root@localhost nginx-1.12.0]# cd src/core ## 进入此目录下
[root@localhost core]# vim nginx.h ## 编辑 nginx.h
找到#define NGINX_VER
修改值为："nginx"
b.修改gcc
[root@localhost core]# cd nginx-1.12.0/ ## 回到源码目录
[root@localhost nginx-1.12.0]# cd auto/cc/ ## 进入此目录下
[root@localhost cc]# vim gcc ## 编辑gcc
## 找到如下两行(在最后)，注释掉即可
# debug
#CFLAGS="$CFLAGS -g" ## 注释掉此行
9.重新安装
[root@localhost cc]# cd nginx-1.12.0/ ## 回到源码目录
## 重新安装
[root@localhost nginx-1.12.0]# ./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module
## 再执行make 和 make install
[root@localhost nginx-1.12.0]# cd /usr/local/nginx/sbin ##进入目录下
[root@localhost sbin]# ./nginx ## 开启
[root@localhost sbin]# netstat -antlp ## 查看端口号为80
测试
[root@localhost sbin]# curl -I localhost ## 测试
HTTP/1.1 200 OK
Server: nginx ## 版本号已经不再显示

## 通过du命令查看文件大小
[root@localhost sbin]# du nginx

安装jdk，配环境变量
1.解压版(需要配环境变量)
下载后解压到目录下
[root@localhost ~]# tar zxf jdk-8u121-linux-x64.tar.gz -C /usr/local/java ## 将jdk解压到 /usr/local/java 下
2.安装版rpm(不用配环境变量)
直接执行
[root@foundation78 Desktop]# yum install -y jdk-8u121-linux-x64.rpm
3.配环境变量(只针对解压版)
## 配环境变量
[root@localhost ～]# vim /etc/profile ## 编辑该文件
## 在最后一行配环境变量
export JAVA_HOME=/usr/local/java/jdk1.8.0_121
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$PATH:$JAVA_HOME/bin
[root@localhost ~]# source /etc/profile ## 加载配置文件
4.检测
## 查看jdk配置
[root@foundation78 Desktop]# java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)
## 查看jre配置
[root@foundation78 Desktop]# javac -version
javac 1.8.0_121
5.查看jdk路径
[root@foundation78 Desktop]# which java
/usr/bin/java
[root@foundation78 Desktop]# which javac
/usr/bin/javac

安装Redis
1.下载
[root@iZwz991stxdwj560bfmadtZ local]# wget http://download.redis.io/releases/redis-4.0.6.tar.gz
2.解压
[root@iZwz991stxdwj560bfmadtZ local]# tar -zxvf redis-4.0.6.tar.gz
3.yum安装gcc依
[root@iZwz991stxdwj560bfmadtZ local]# yum install gcc
4.跳转到redis解压目录下
[root@iZwz991stxdwj560bfmadtZ local]# cd redis-4.0.6
5.编译安装
[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# make MALLOC=libc
[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src && make install
CC Makefile.dep
Hint: It's a good idea to run 'make test' ;)
INSTALL install
INSTALL install
INSTALL install
INSTALL install
INSTALL install
6.启动redis的三种方式
[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src
a、直接启动redis
[root@iZwz991stxdwj560bfmadtZ src]# ./redis-server
18685:C 13 Dec 12:56:12.507 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
18685:C 13 Dec 12:56:12.507 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18685, just started
18685:C 13 Dec 12:56:12.507 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf

18685:M 13 Dec 12:56:12.508 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.
18685:M 13 Dec 12:56:12.508 * Ready to accept connections
如上图：redis启动成功，但是这种启动方式需要一直打开窗口，不能进行其他操作，不太方便。
按 ctrl + c可以关闭窗口。
b、以后台进程方式启动redis
第一步：修改redis.conf文件
将
daemonize no
修改为
daemonize yes
第二步：指定redis.conf文件启动
[root@iZwz991stxdwj560bfmadtZ src]# ./redis-server /usr/local/redis-4.0.6/redis.conf
18713:C 13 Dec 13:07:41.109 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
18713:C 13 Dec 13:07:41.109 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18713, just started
18713:C 13 Dec 13:07:41.109 # Configuration loaded
第三步：关闭redis进程
首先使用ps -aux | grep redis查看redis进程
[root@iZwz991stxdwj560bfmadtZ src]# ps -aux | grep redis
root 18714 0.0 0.1 141752 2008 ? Ssl 13:07 0:00 ./redis-server 127.0.0.1:6379
root 18719 0.0 0.0 112644 968 pts/0 R+ 13:09 0:00 grep --color=auto redis
# 使用kill命令杀死进程
[root@iZwz991stxdwj560bfmadtZ src]# kill 18714
c、设置redis开机自启动
1、在/etc目录下新建redis目录
2、将/usr/local/redis-4.0.6/redis.conf 文件复制一份到/etc/redis目录下，并命名为6379.conf
3、将redis的启动脚本复制一份放到/etc/init.d目录下
4、设置redis开机自启动
先切换到/etc/init.d目录下
然后执行自启命令
[root@iZwz991stxdwj560bfmadtZ etc]# mkdir redis
[root@iZwz991stxdwj560bfmadtZ redis]# cp /usr/local/redis-4.0.6/redis.conf /etc/redis/6379.conf
[root@iZwz991stxdwj560bfmadtZ init.d]# cp /usr/local/redis-4.0.6/utils/redis_init_script /etc/init.d/redis
[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redis on
service redisd does not support chkconfig
看结果是redisd不支持chkconfig
解决方法：
使用vim编辑redisd文件，在第一行加入如下两行注释，保存退出
#!/bin/sh
# chkconfig: 2345 90 10
# description: Redis is a persistent key-value database
注释的意思是，redis服务必须在运行级2，3，4，5下被启动或关闭，启动的优先级是90，关闭的优先级是10。
再次执行开机自启命令chkconfig redis on，成功
启动：
service redis start
关闭：
方法1：service redisd stop
方法2：redis-cli SHUTDOWN
