linux基本項目環(huán)境搭建

java環(huán)境搭建

獲取java源碼包

將本地jdk-8u144-linux-x64.tar.gz通過xftp上傳到ECS的指定目錄下（一般為/usr/local/java）

解壓

tar zxvf jdk-8u144-linux-x64.tar.gz
z：調(diào)用gzip命令在文件打包過程中壓縮/解壓文件
x：打包文檔中還原出文件
v：顯示命令執(zhí)行過程
f：指定備份文件

配置環(huán)境變量

vim /etc/profile
在文件末尾加上

#set java environment JAVA_HOME=/usr/local/java/jdk1.8.0_144 CLASSPATH=.:$JAVA_HOME/lib.tools.jar PATH=$JAVA_HOME/bin:$PATH export JAVA_HOME CLASSPATH PATH

使配置文件生效

source /etc/profile

驗證

[root@iZwz9938t1plpkhn7ajjkrZ java]# java -version java version "1.8.0_144" Java(TM) SE Runtime Environment (build 1.8.0_144-b01) Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)

nginx安裝

配置(configure)

引用 http://blog.sina.com.cn/s/blog_406127500101dsmy.html
源碼的安裝一般由3個步驟組成：配置(configure)、編譯(make)、安裝(make install)。

Configure是一個可執(zhí)行腳本，它有很多選項，在待安裝的源碼路徑下使用命令./configure –help輸出詳細的選項列表。

其中–prefix選項是配置安裝的路徑，如果不配置該選項，安裝后可執(zhí)行文件默認放在/usr /local/bin，庫文件默認放在/usr/local/lib，配置文件默認放在/usr/local/etc，其它的資源文件放在/usr /local/share，比較凌亂。

如果配置–prefix，如：
./configure --prefix=/usr/local/test
可以把所有資源文件放在/usr/local/test的路徑中，不會雜亂。
用了—prefix選項的另一個好處是卸載軟件或移植軟件。當(dāng)某個安裝的軟件不再需要時，只須簡單的刪除該安裝目錄，就可以把軟件卸載得干干凈凈；移植軟件只需拷貝整個目錄到另外一個機器即可（相同的操作系統(tǒng)）。

當(dāng)然要卸載程序，也可以在原來的make目錄下用一次make uninstall，但前提是make文件指定過uninstall。

[root@iZwz9ezkmfgg9sw1ujpt5zZ nginx-1.12.2]# ./configure --prefix=/usr/local/nginx/ checking for OS+ Linux 3.10.0-693.2.2.el7.x86_64 x86_64 checking for C compiler ... found+ using GNU C compiler+ gcc version: 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) ...checking for PCRE library in /usr/include/pcre/ ... not found checking for PCRE library in /usr/pkg/ ... not found checking for PCRE library in /opt/local/ ... not found./configure: error: the HTTP rewrite module requires the PCRE library. You can either disable the module by using --without-http_rewrite_module option, or install the PCRE library into the system, or build the PCRE library statically from the source with nginx by using --with-pcre=<path> option.

缺少PCRE library，正則表達式庫，nginx中l(wèi)ocation匹配要用到的一種。
安裝正則表達式庫

配置

配置用戶名與郵箱，僅僅作為提交用戶身份證（待測試）

[root@izwz91rl2qyews1sgkymi9z ~]# git config --global user.name "設(shè)置一個用戶名，字符串A" [root@izwz91rl2qyews1sgkymi9z ~]# git config --global user.email "你的郵箱，字符串B"

查看
進入$HOME(/root,可用echo輸出驗證)，會有一個.gitconfig文件。

[root@izwz91rl2qyews1sgkymi9z ~]# cat .gitconfig [user]name = 前面的字符串Aemail = 前面的字符串B [root@izwz91rl2qyews1sgkymi9z ~]# pwd /root [root@izwz91rl2qyews1sgkymi9z ~]#

生成SSH公鑰
將生成的公鑰放在GitHub上面

[root@iZwz9938t1plpkhn7ajjkrZ ~]# cat .gitconfig [user]name = gczxemail = new_thread@yeah.net [root@iZwz9938t1plpkhn7ajjkrZ ~]# ssh-keygen -t rsa -C "new_thread@yeah.net" Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: SHA256:PL0vkEq+FSC0yMsGvUUT0LO8yfiN2p5JHkUSoN0/e04 new_thread@yeah.net The key's randomart image is: +---[RSA 2048]----+ | o+*. | | = =o+ | |o =.*oo | | o +o= o . | | =o o+ S.. | | .. +..ooo . | | .o=..E.. | | +o++= .. | | .o* ... .. | +----[SHA256]-----+ [root@iZwz9938t1plpkhn7ajjkrZ ~]#

這個是已經(jīng)生成ssh的，重新生成的過程。

[root@izwz91rl2qyews1sgkymi9z ~]# ssh-keygen -t rsa -C "new_thread@yeah.net" Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): /root/.ssh/id_rsa already exists. Overwrite (y/n)? [root@izwz91rl2qyews1sgkymi9z ~]#
