工作需要，为一台空白服务器安装apache，小白程序员，搞了一个下午，惭愧！ 工具需要，也可以自己到apache下载 http://httpd.apache.org/download.cgi 遇到的bug apr-1.5.1.tar.gz apr-util.1.5.4.tar.gz 都是不是最新版本的，因为我用最新版安装，总是make install失败。所以放弃了 1.第一步 准备工作，先安装gcc C++ （百度有些文档是最后安装，我这里先安装了，这里需要root权限） [root@localhost /]# yum install gcc-c++2. 第二步 1.下载安装包，需要下面3个安装包，把安装包用ftp拉到对应的目录下去。 [root@bes2 apache]# ll -rw-r--r--. 1 root root 1020833 9月 18 17:47 apr-1.5.1.tar.gz -rw-r--r--. 1 root root 874462 9月 18 17:48 apr-util-1.5.3.tar.gz -rw-r--r--. 1 root root 6820719 9月 18 17:40 httpd-2.4.10.tar.gz [apps@app-srm-dev-1 ~]$ cd svr [apps@app-srm-dev-1 svr]$ ll

Why does using the u and i modifiers cause one version of a pattern to take ~10x more steps than another?

由 ▼魔方 西西 提交于 2020-01-23 04:03:21
问题 I was testing two almost identical regexes against a string (on regex101.com), and I noticed that there was a huge difference in the number of steps that they were taking. Here are the two regexes: (Stake: £)(\d+(?:\.\d+)?) (winnings: £)(\d+(?:\.\d+)?) This is the string I was running them against (with modifiers g , i , m , u ): Start Game, Credit: £200.00game num: 1, Stake: £2.00Spinning Reels:NINE SEVEN KINGKING STAR ACEQUEEN JACK KINGtotal winnings: £0.00End Game, Credit: £198Start...

“'\w' is an unrecognized escape” in grep

由 自闭症网瘾萝莉.ら 提交于 2020-01-21 03:02:56
问题 I'm using grep in some projects in R (which uses a perl=TRUE flag) and for the life of me I can't figure out why R keeps throwing errors. My query is as follows: d$SomeColumn[grep("(?ix)<VNW[^;]*;(dis|dat)> \w*<N\(", d$Right, perl=TRUE)] <- 1 However, R throws the following error: Error: '\w' is an unrecognized escape in character string starting ""<VNW[^;]*;(dis|dat)> \w" 回答1: You need to escape the backslashes one more time in r. d$SomeColumn[grep("(?ix)<VNW[^;]*;(dis|dat)> \\w*<N\\(", d

PCRE: pattern for unicode characters (hex code)

由 烂漫一生 提交于 2020-01-16 19:39:09
问题 What is the PCRE pattern, in PHP, for characters with hex code from \x00 to \xFF ? 回答1: To match a specific Unicode code point, use \uFFFF where FFFF is the hexadecimal number of the code point you want to match. You must always specify 4 hexadecimal digits . E.g. \u00E0 matches "à", but only when encoded as a single code point U+00E0.
