一.安裝并配置Nginx服務器

- 在nginx1(192.168.1.10)上安裝nginx
# 安裝編譯器
[root@nginx1 ~]# yum install -y gcc pcre-devel zlib-devel

# 編譯安裝nginx
[root@nginx1 ~]# tar xf nginx-1.12.2.tar.gz
[root@nginx1 ~]# cd nginx-1.12.2
[root@nginx1 nginx-1.12.2]# ./configure
[root@nginx1 nginx-1.12.2]# make && make install
```

- 安裝php-fpm

[root@nginx1 ~]# yum install -y php-fpm

[root@nginx1 ~]# systemctl start php-fpm

[root@nginx1 ~]# ss -tlnp | grep :9000
LISTEN???? 0????? 128??? 127.0.0.1:9000???????????????????? *:*?????????????????? users:(("php-fpm",pid=11310,fd=0),("php-fpm",pid=11309,fd=0),("php-fpm",pid=11308,fd=0),("php-fpm",pid=11307,fd=0),("php-fpm",pid=11306,fd=0),("php-fpm",pid=11305,fd=6))
```

- 修改配置文件

[root@nginx1 ~]# vim +65 /usr/local/nginx/conf/nginx.conf
??????? location ~ \.php$ {
??????????? root?????????? html;
??????????? fastcgi_pass?? 127.0.0.1:9000;
??????????? fastcgi_index? index.php;
??????? #??? fastcgi_param? SCRIPT_FILENAME? /scripts$fastcgi_script_name;
??????????? include??????? fastcgi.conf;
??????? }
```

- 啟動nginx服務

[root@nginx1 ~]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

[root@nginx1 ~]# /usr/local/nginx/sbin/nginx

[root@nginx1 ~]# ss -tlnp | grep :80
LISTEN???? 0????? 128????????? *:80?????????????????????? *:*?????????????????? users:(("nginx",pid=11376,fd=6),("nginx",pid=11375,fd=6))
```

- 測試

[root@nginx1 ~]# vim /usr/local/nginx/html/test.php
<?php
??? echo "Hello World!\n";
??? phpinfo();
?>

[root@nginx1 ~]# curl http://127.0.0.1/test.php
Hello World!
... ...
```

二.安裝redis

[root@redis1 ~]# yum install -y gcc
[root@redis1 ~]# wget https://download.redis.io/releases/redis-4.0.8.tar.gz
[root@redis1 ~]# tar xf redis-4.0.8.tar.gz
[root@redis1 ~]# cd redis-4.0.8

# 修改安裝目錄為/usr/local/redis
[root@redis1 redis-4.0.8]# vim +27 src/Makefile
PREFIX?=/usr/local/redis

# 編譯安裝
[root@redis1 redis-4.0.8]# make && make install

# 將redis命令目錄添加至PATH環境變量
[root@redis1 redis-4.0.8]# vim /etc/bashrc?? # 尾部追加
export PATH=$PATH:/usr/local/redis/bin
[root@redis1 redis-4.0.8]# source /etc/bashrc

# 初始化redis服務
[root@redis1 redis-4.0.8]# ./utils/install_server.sh? # 全部問題直接回車采用默認值

三.配置PHP支持Redis

- 安裝php擴展
[root@nginx1 ~]# yum install -y php-devel automake autoconf
```

- 安裝php-redis

下載地址

http://windows.php.net/downloads/pecl/snaps/redis/2.2.5/
[root@nginx1 ~]# tar xf redis-cluster-4.3.0.tgz
[root@nginx1 ~]# cd redis-4.3.0/
[root@nginx1 redis-4.3.0]# phpize
[root@nginx1 redis-4.3.0]# ./configure --with-php-config=/usr/bin/php-config
[root@nginx1 redis-4.3.0]# make && make install

[root@nginx1 redis-4.3.0]# ls /usr/lib64/php/modules/redis.so
/usr/lib64/php/modules/redis.so
?

- 修改php配置文件并重啟服務

[root@nginx1 redis-4.3.0]# vim /etc/php.ini?? # 在730行下添加
extension_dir = "/usr/lib64/php/modules"
extension = "redis.so"

[root@nginx1 ~]# systemctl restart php-fpm
```

- 測試

# 創建腳本，寫入redis數據庫
[root@nginx1 ~]# vim /usr/local/nginx/html/set_redis.php

<?php
??? $redis = new redis();
??? $redis->connect("192.168.1.11", "6379");
??? $redis->auth("tedu.cn");
??? $redis->set("username", "tom");
?>

# 創建腳本，讀取redis數據
[root@nginx1 ~]# vim /usr/local/nginx/html/get_redis.php
<?php
??? $redis = new redis();
??? $redis->connect("192.168.1.11", "6379");
??? $redis->auth("tedu.cn");
??? echo $redis->get("username");
?>

# 訪問測試頁面
[root@nginx1 ~]# curl http://127.0.0.1/set_redis.php
[root@nginx1 ~]# curl http://127.0.0.1/get_redis.php
tom

# 在redis數據庫上查看
[root@redis1 ~]# redis-cli -a tedu.cn
127.0.0.1:6379> KEYS *
1) "username"
127.0.0.1:6379> GET username
"tom"
