### 1、准备

创建用户（http://examplecode.cn/2018/09/03/centos-create-user/）

### 2、安装jdk

下载

```

wget http://download.oracle.com/otn-pub/java/jdk/7u75-b13/jdk-7u75-linux-x64.rpm?AuthParam=1423536068_606ebcad3a2baff3dd5a4d7ec00a4e4e

rpm -ivh *.rpm

```

设置环境变量

```

JAVA_HOME=/usr/java/jdk1.7.0_40

CLASSPATH=$JAVA_HOME/lib:$JAVA_HOME/jre/lib

PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin

export PATH CLASSPATH JAVA_HOME

```

### 3、安装tomcat

下载链接：[http://tomcat.apache.org/download-80.cgi](http://tomcat.apache.org/download-80.cgi)

![20180927093334606.png](https://upload-images.jianshu.io/upload_images/1721864-a7e14fb52489b221.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240)

在 /usr/local下创建一个tomcat8文件夹

```

sudo mkdir tomcat8

```

将之前下载的包放到该目录下解包

```

tar -xvf apache-tomcat-8.5.42.tar

// 然后删除安装包

rm apache-tomcat-8.5.42.tar

```

修改环境变量

在 /etc/profile 末尾添加如下配置

```

CATALINA_BASE=/usr/local/tomcat8/apache-tomcat-8.5.42 PATH=$PATH:$CATALINA_BASE/bin

#export 使上述配置⽣效

export CATALINA_BASE PATH

```

sudo vi /etc/profile

```

重新加载环境变量

```

source /etc/profile

```

防火墙相关命令

查看防火墙命令：firewall-cmd --state或者systemctl status firewallld

开启防火墙：systemctl start firewalld

关闭防火墙：systemctl stop firewalld

重启防火墙：firewall-cmd --reload

配置防火墙，开放8080端口

```

firewall-cmd --zone=public --add-port=8080/tcp --permanent

firewall-cmd --reload

```

export ORACLE_BASE=/data/oracle

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1

#oracle启动数据库实例名

export ORACLE_SID=orcl11g

#添加系统环境变量

export PATH=$ORACLE_HOME/bin:/usr/sbin:$PATH

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib

export TNS_ADMIN=$ORACLE_HOME/network/admin

```

7、解压两个安装文件到对应的文件夹下

9、建立swap分区

```

dd if=/dev/zero of=/home/swap bs=1024 count=2097152 #bs为单位，count为设置的大小2048*1024

mkswap /home/swap #格式化交换文件

swapon /home/swap #立即启用交换分区文件, 要停止使用新创建的swap文件,只要执行 swapoff/home/swap命令即可.

```

查看分区情况 free -m

```

`vim /etc/fstab 添加一行`

`/home/swap swap swap defaults 0 0`

`否则重启后 swap分区会失效`

10、进行安装

```

su - oracle #切换为oracle执行以下安装操作

cd /data/database/database

./runInstaller -silent -ignorePrereq -ignoreSysPrereqs -responseFile /data/database/database/response/db_install.rsp

```

10.1、报错

`[oracle@CuteMonkey database]$ [SEVERE] - Email Address Not Specified`

[metalink](https://support.oracle.com/epmos/faces/MosIndex.jspx?_afrLoop=359723547792692&_afrWindowMode=0&_adf.ctrl-state=pbz9bmzer_4)

11、使用root用户运行

```

su - root

/data/oraInventory/orainstRoot.sh

/data/oracle/product/11.2.0/db_1/root.sh

```

12、配置tnsnames.ora

```

vim /data/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora

#新增如下内容：

alioracle =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 主机名称hostname)(PORT = 1521))

)

(CONNECT_DATA =

(SERVICE_NAME = orcl)

)

```

13、建库（oracle用户）

```

cd /data/oracle/product/11.2.0/db_1/bin

./dbca -silent -responseFile /data/database/database/response/dbca.rsp

#需要输入oracle用的用户名和密码

```

验证是否成功

```

cd /data/oracle/product/11.2.0/db_1/bin

./sqlplus "/as sysdba"

select * from tabs;

会有非常多数据输出来

```

14、配置listener.ora

```

vim /data/oracle/product/11.2.0/db_1/network/admin/listener.ora

#新增如下内容：

LISTENER=(DESCRIPTION_LIST=(DESCRIPTION=

(ADDRESS=(PROTOCOL=TCP)(HOST=39.100.46.240)(PORT=1521))

)

SID_LIST_LISTENER=

(SID_LIST=

(SID_DESC=

(GLOBAL_DBNAME=orcl)

(SID_NAME=orcl11g)

(ORACLE_HOME=/data/oracle/product/11.2.0/db_1)

(PRESPAWN_MAX=20)

(PRESPAWN_LIST=

(PRESPAWN_DESC=(PROTOCOL=tcp)(POOL_SIZE=2)(TIMEOUT=1))

)

```

15、创建用户

```

lsnrctl start

(如何提示没有此命令,可以在.bashprofile里增加export PATH=.:${PATH}:$HOME/bin:$ORACLE_HOME/bin)

创建oracle用户

sqlplus "/as sysdba"

create user test identified by test123(这个是口令);

//赋予test登录和创建表等资源权限

grant resource,conn to test;

//赋予test用户dba权限,此权限涵盖较多,一般上面足够

grant dba to test;

revoke 取消权限

```

`Oracle中文乱码的问题¿¿`

[参考链接](https://www.linuxidc.com/Linux/2011-04/34359.htm)

```

1、ssh登录，切换到oracle用户

切换用户命令：su -oracle

之后用sqlplus登录oracle，命令：

:sqlplus /nolog

:connect /as sysdba

这样就登录了。

2、更改字符集

首先 sqlplus登录后，关闭oracle数据库

1.shutdown immediate ;

2.startup mount ;

3.alter system enable restricted session ;

4.alter system set JOB_QUEUE_PROCESSES=0;

5.alter system set AQ_TM_PROCESSES=0;

6.alter database open ;

7. alter database character set INTERNAL_USE ZHS16GBK;

8.shutdown immediate ;

9.startup ;

```

### 配置redis

root 用户创建redis文件夹

```

cd /redis

```

1、下载redis

```

wget http://download.redis.io/releases/redis-4.0.2.tar.gz

```

解压

```

tar -xzvf redis-4.0.2.tar.gz

```

2、安装

```

cd redis-4.0.2

```

执行make命令编译：

```

make

```

make命令成功后，执行安装命令

```

make install

```

安装完成

3、配置Redis

centos下配置随机启动需要在目录/etc/init.d中添加启动脚本，启动脚本的模板在redis源代码目录的utils文件夹中：redis_init_script，拷贝到/etc/init.d下并命名为：redis_6379

```

cp redis_init_script /etc/init.d/redis_6379

```

创建目录/etc/redis。配置文件的模板还在在redis源码中找：redis-4.0.2/redis.conf，将这个配置文件复制到/etc/redis目录，并重命名为6379.conf。

![屏幕快照 2019-07-04 下午5.52.31.png](https://upload-images.jianshu.io/upload_images/1721864-f1d165eb42967d12.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240)

```

cp redis.conf /etc/redis/6379.conf

```

修改6379.conf。

```

# 注释掉它，以便让外网访问

# bind 127.0.0.1

# 关闭保护模式

protected-mode no

# Redis默认不是以守护进程的方式运行，可以通过该配置项修改，使用yes启用守护进程

# 启用守护进程后，Redis会把pid写到一个pidfile中，在/var/run/redis.pid

daemonize yes

# 当Redis以守护进程方式运行时，Redis默认会把pid写入/var/run/redis.pid文件，可以通过pidfile指定

pidfile /var/run/redis_6379.pid

# 指定Redis监听端口，默认端口为6379

# 如果指定0端口，表示Redis不监听TCP连接

port 6379

# 工作目录.

# 指定本地数据库存放目录，文件名由上一个dbfilename配置项指定

# Also the Append Only File will be created inside this directory.

# 注意，这里只能指定一个目录，不能指定文件名

dir /var/redis/6379

```

最后一行 /var/redis/6379 这个目录还没有，需要我们创建，用于存放redis的持久化文件。

![屏幕快照 2019-07-04 下午6.00.45.png](https://upload-images.jianshu.io/upload_images/1721864-ad1ce024a7d80a87.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240)

然后执行命令：

```

#设置开机执行redis脚本

chkconfig redis_6379 on

```

错误：`service redis_6379 does not support chkconfig`

在redis_6379开头加两行注释：

```

# chkconfig: 2345 90 10

# description: Redis is a persistent key-value database

```

通过上面的操作后，我们就可以通过如下命令启动，停止redis了

```

service redis_6379 start

service redis_6379 stop

```

### 配置nginx

1、首先安装PCRE pcre功能是让nginx有rewrite功能

```

cd /usr/local/pcre

　　下载PCRE：wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

　　解压安装包：tar zxvf pcre-8.35.tar.gz

　　进入安装包目录：cd pcre-8.35

　　编译：./configure

　　安装：make && make install

　　查看安装版本：pcre-config –version 如果出现版本号，说明安装成功

　　检查系统里是否安装了pcre软件

　　rpm -qa pcre 如果没有显示说明没有安装反之安装过

　　rpm -e –nodeps pcre 删除pcre

```

安装zlib库

```

cd /usr/local/

$ wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.36.tar.gz

$ tar -zxvf pcre-8.36.tar.gz

$ cd pcre-8.36

$ ./configure

$ make

$ make install

```

3、安装nginx

```

cd /nginx

　　下载nginx：wget http://nginx.org/download/nginx-1.6.2.tar.gz

　　解压安装包： tar zxvf nginx-1.6.2.tar.gz

　　进入安装包目录：cd nginx-1.6.2

　　配置：./configure

　　编译安装：make && make install

```

4.nginx 配置

进入 nginx/conf 目录下，配置 nginx.conf 文件

```

vi nginx.conf

```

5.nginx 常用命令

进入到 sbin 目录下:

```

./nginx 启动

./nginx -s stop 相当于 pkill -9 nginx =====》强制杀死 nginx 进程

./nginx -t 测试 nginx 是否配置正确

./nginx -s quit 待nginx进程处理任务完毕进行停止

./nginx -s reload 重启

```

### 其他

Permission denied权限

如果出现Permission denied要么使用sudo权限去执行

如果1不行就说明当前文件夹确实没有指定的权限

```

文件夹

chmod -R 777 【路径】

文件

chmod 777 【路径】

//首先声明这样做有风险，而且请注意这里的r是大写！RRR

```

删除文件

```

1、删除文件夹命令

rm -rf /var/log/httpd/access

将会删除/var/log/httpd/access目录以及其下所有文件、文件夹

2、删除文件命令

rm -f /var/log/httpd/access.log

```
